Wilshire 4500 Completion ETF

Wilshire 4500 Completion ETF (WXSP)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Wilshire 4500 Completion Index^SM (the “Wilshire 4500” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Wilshire 4500 Completion ETF
Management fees		0.18%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Acquired Fund Fees and Expenses	[2]	0.02%
Total annual Fund operating expenses		0.20%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Wilshire 4500 Completion ETF	20	119	227	543

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the Fund’s fiscal year ended August 31, 2012, the Fund’s portfolio turnover rate was 15% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire 4500 (Index Ticker: W4500). The Wilshire 4500 is a rules-based index comprised of, as of November 30, 2012, approximately 3,218 securities of U.S. issuers, including common stocks, real estate investment trusts (“REITs”) and business development companies (“BDCs”). The Index may include securities of companies of all categories of market capitalizations (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire 4500 is a subset of the Wilshire 5000 Total Market IndexSM (the “Wilshire 5000”). Designed to represent the extended market, the Wilshire 4500 is the Wilshire 5000 with the components of the S&P 500 Index® excluded.

The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire 4500. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire 4500. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser and Investment Sub-Adviser use quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The 1940 Act, imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund utilizes a sampling approach (or if it otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one year and since inception compare with those of the Index and a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available at www.guggenheimfunds.com.

Calendar Year Total Return as of 12/31

The Fund commenced operations on March 9, 2010. The Fund’s year-to-date return was 14.25% as of September 30, 2012.

During the periods shown in the chart above, the Fund’s highest and lowest calendar quarter returns were 13.22% and -20.61%, respectively, for the quarters ended December 31, 2011 and September 30, 2011. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local tax. Your own actual after-tax returns will depend on your tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Shares of the Fund in tax-deferred accounts such as individual retirement accounts (IRAs) or employee-sponsored retirement plans.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees of Claymore Exchange-Traded Fund Trust (the "Trust") has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] Acquired fund fees and expenses refer to the Fund's pro rata portion of the management fees and operating expenses of the business development companies in which the Fund invests. Since acquired fund fees and expenses are not directly borne by the Fund, they are not reflected in the Fund's financial statements with the result that the information presented in the table will differ from that presented in the Fund's financial highlights.

Guggenheim Spin-Off ETF

Guggenheim Spin-Off ETF (CSD)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Beacon Spin-off Index (the “Spin-off Index” or “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Spin-Off ETF	66	262	560	1,408

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 77% of the average value of its portfolio

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Spin-off Index (Index Ticker: CLRSOTR). As of November 30, 2012, the Spin-off Index was comprised of approximately 24 securities selected, based on investment and other criteria, from a broad universe of U.S.-traded stocks, American depositary receipts (“ADRs”) and master limited partnerships (“MLPs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of companies eligible for inclusion in the Index includes companies that have been spun-off within the past 30 months (but not more recently than six months prior to the applicable rebalancing date), without limitations on market capitalization (including micro-cap securities), but which are primarily small- and mid-cap companies with capitalizations under $10.0 billion. The time period from being spun-off may be extended to compensate for periods where there are too few new spin-offs to populate the Index. Beacon Indexes LLC (“Beacon” or the “Index Provider”) defines a spin-off company as any company resulting from either of the following events: a spin-off distribution of stock of a subsidiary company by its parent company to parent company shareholders or equity “carve-outs” or “partial initial public offerings” in which a parent company sells a percentage of the equity of a subsidiary to public shareholders. The Fund will invest at least 90% of its total assets in common stock, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Industrial Sector Risk. The stock prices of companies in the industrial sector are affected by supply and demand both for their specific product or service and for industrial sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulation, world events and economic conditions may affect the performance of companies in the industrial sector. Companies in the industrial sector may be at risk for environmental damage and product liability claims.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. The telecommunications sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid obsolescence and research and development of new products. Other risks include those related to regulatory changes, such as the uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or futures or other derivative positions, or otherwise holds investments other than those which comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Guggenheim BRIC ETF

Guggenheim BRIC ETF (EEB)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called BNY Mellon BRIC Select ADR Index (the “BRIC Index” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker. 

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim BRIC ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		0.16%
Total annual Fund operating expenses		0.66%
Expense reimbursements	[2]	0.02%
Total annual Fund operating expenses after expense reimbursements		0.64%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim BRIC ETF	65	259	473	1,091

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the BRIC Index (Index Ticker: BKBRICT). The BRIC Index is comprised of American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) selected, based on liquidity, from a universe of all listed depositary receipts of companies from Brazil, Russia, India and China currently trading on U.S. exchanges. The depositary receipts that comprise the Index may be sponsored or unsponsored. The companies in the universe are selected using a proprietary methodology developed by The Bank of New York Mellon (the “Index Provider” or “BNY Mellon”). The Fund will invest at least 90% of its total assets in ADRs and GDRs that comprise the Index and underlying securities representing ADRs and GDRs that comprise the Index. As of November 30, 2012, the Index consisted of 76 securities. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by the depositary receipts comprising the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs and GDRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Brazil has experienced substantial economic instability resulting from, among other things, periods of very high inflation, persistent structural public sector deficits and significant devaluations of the currency of Brazil, and leading also to a high degree of price volatility in both the Brazilian equity and foreign currency markets. Brazilian companies may also be adversely affected by high interest and unemployment rates, and are particularly sensitive to fluctuations in commodity prices.

Investing in securities of Russian companies involves additional risks, including, among others, the absence of developed legal structures governing private or foreign investments and private property; the possibility of the loss of all or a substantial portion of the Fund’s assets invested in Russia as a result of expropriation; certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests; and potentially greater price volatility in, significantly smaller capitalization of, and relative illiquidity of, some of these markets.

Investing in securities of Indian companies involves additional risks, including, but not limited to, greater price volatility, substantially less liquidity and significantly smaller market capitalization of securities markets, more substantial governmental involvement in the economy, higher rates of inflation and greater political, economic and social uncertainty. Furthermore, future actions of the Indian Government or religious and ethnic unrest could have a significant impact on the economy.

Investing in securities of Chinese companies involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, previously the Chinese government has from time to time taken actions that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate in particular industries, induce mergers between companies in certain industries and induce private companies to publicly offer their securities to increase or continue the rate of economic growth, control the rate of inflation or otherwise regulate economic expansion. It may do so in the future as well, potentially having a significant adverse effect on economic conditions in China, the economic prospects for, and the market prices and liquidity of, the securities of China companies and the payments of dividends and interest by China companies.

China Exposure Risk. From time to time, certain of the companies comprising the BNY Mellon BRIC Index that are located in China may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries identified by the U.S. government as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations which could negatively affect the company’s performance, and/or could suffer damage to its reputation if it is identified as a company which invests or deals with countries which are identified by the U.S. government as state sponsors of terrorism or subject to sanctions. As an investor in such companies, the Fund is indirectly subject to those risks.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs and GDRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. GDRs are similar to ADRs, but may be issued in bearer form and are typically offered for sale globally and held by a foreign branch of an international bank. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs and GDRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs and GDRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs and GDRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. The telecommunications sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid obsolescence and research and development of new products. Other risks include those related to regulatory changes, such as the uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ stocks may be more volatile and less liquid than those of larger, more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, or otherwise holds investments other than those which comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Zacks Multi-Asset Income Index (the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Multi-Asset Income ETF	79	300	560	1,304

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 113% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Zacks Multi-Asset Income Index (Index Ticker: ZAXYHTR). As of November 30, 2012, the Zacks Multi-Asset Income Index was comprised of approximately 149 securities selected, based on investment and other criteria, from a universe of domestic and international companies. The securities comprising the Index include stocks of small and medium-sized companies. The universe of securities within the Index includes U.S. listed common stocks and American depositary receipts (“ADRs”) paying dividends, real estate investment trusts (“REITs”), master limited partnerships (“MLPs”), closed-end funds, Canadian royalty trusts and traditional preferred stocks. The depositary receipts included in the Index may be sponsored or unsponsored. The companies in the universe are selected using a proprietary methodology developed by Zacks Investment Research, Inc. (“Zacks” or the “Index Provider”). The Fund will invest at least 90% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its objective. Sampling means that the Investment Adviser uses quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include industry weightings, market capitalization and other financial characteristics of securities. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Preferred Stock Risk. There are certain additional risks associated with investing in preferred securities, including, but not limited to, (i) preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer; (ii) preferred securities are generally subordinated to bonds and other debt instruments in a company’s capital structure in terms of having priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt instruments; preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. Government securities; generally, traditional preferred securities offer no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board; in certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Canadian Royalty Trust Risk. As the Fund invests in Canadian royalty trusts, it is subject to the following risks applicable to Canadian royalty trusts:

Lack of diversification. The royalty trusts in which the Fund invests are heavily invested in oil and gas.

Potential sacrifice of growth. Potential growth may be sacrificed because revenue is passed on to a royalty trust’s unit holders (such as the Fund), rather than reinvested in the business.

No guarantees. Royalty trusts generally do not guarantee minimum distributions or even return of capital. If the assets underlying a royalty trust do not perform as expected, the royalty trust may reduce or even eliminate distributions. The declaration of such distributions generally depends upon various factors, including the operating performance and financial condition of the royalty trust and general economic conditions.

Potential for tax recharacterization or changes. Under amendments to the Income Tax Act (Canada) passed in 2007 (the “SIFT Rules”), certain trusts (defined as “SIFT trusts”) are taxable on certain income and gains on a basis similar to that which applies to a corporation, with the result that tax efficiencies formerly available in respect of an investment in the trust may cease to be available. A royalty trust may be a SIFT trust. In addition, as a result of the SIFT Rules, some trusts may undertake reorganization transactions, the costs of which may affect the return earned on an investment in the trust. After any such conversion, tax efficiencies that were formerly available in respect of an investment in the trust may cease to be available. Accordingly, the SIFT Rules have had and may continue to have an effect on the trading price of investments in royalty trusts, and consequently could impact the value of Shares of the Fund.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ stocks may be more volatile and less liquid than those of larger, more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market.

Below-Investment Grade Securities Risk. The Fund may invest in certain preferred stocks that are rated below investment grade. Preferred stocks that are not investment grade are high yield, high risk securities. These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative by the major credit rating agencies. Preferred stocks rated below investment grade may be issued by companies that are restructuring, are smaller and less creditworthy, or are more highly indebted than other companies. This means that they may have more difficulty making scheduled dividend payments. Changes in the value of preferred stocks rated below investment grade are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade preferred stocks.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund  utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Fund Performance

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees of Claymore Exchange-Traded Fund Trust (the "Trust") has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] Acquired fund fees and expenses refer to the Fund's pro rata portion of the management fees and operating expenses of the closed-end funds in which the Fund invests. Since acquired fund fees and expenses are not directly borne by the Fund, they are not reflected in the Fund's financial statements with the result that the information presented in the table will differ from that presented in the Fund's financial highlights.

[3] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.60% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees of the Trust (the "Board of Trustees"). To the extent the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Guggenheim Raymond James SB-1 Equity ETF

Guggenheim Raymond James SB-1 Equity ETF (RYJ)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Raymond James SB-1 Equity Index (the “SB-1 Equity Index” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Raymond James SB-1 Equity ETF
Management fees		0.75%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Total annual Fund operating expenses		0.75%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Raymond James SB-1 Equity ETF	77	294	528	1,202

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the SB-1 Equity Index (Index Ticker: RJSBITR). The SB-1 Equity Index is composed of all equity securities rated Strong Buy 1 (“SB-1”) by Raymond James & Associates, Inc. (“Raymond James & Associates”), an affiliate of Raymond James Research Services, LLC (“Raymond James” or the “Index Provider”), as of each rebalance and reconstitution date. Index constituents include equity securities of all market capitalizations, as defined by the Index Provider, that trade on a U.S. securities exchange, including common stocks, American depositary receipts (“ADRs”), real estate investment trusts (“REITs”) and master limited partnerships (“MLPs”). The depositary receipts included in the Index may be sponsored or unsponsored. The number of securities in the Index may vary depending on the number of equity securities rated SB-1 by Raymond James & Associates. The Index generally consists of between 100 and 200 securities and, as of November 30, 2012, the market capitalization range of Index constituents was $24 million to $1 billion. Under normal conditions, the Fund will invest at least 80% of its assets in equity securities. The Fund will invest at least 80% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust (the "Board of Trustees")  may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the total return of the Index less any expenses or distributions. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

Concentration Risk. At any given time, the Fund may invest a substantial portion of its assets in the securities of issuers in any single sector of the economy and may invest up to 25% of its total assets in securities of issuers in one particular industry, and may invest more than 25% of its total assets in securities of issuers in one particular industry in the event that the composition of the issuers of securities rated SB-1 on a rebalancing day results in such an industry concentration in the Index. If the Fund’s investments are focused in a specific industry or sector, the Fund will be subject to more risks, including those risks associated with investment in such industry or sector, than if it were broadly diversified over numerous industries and sectors of the economy.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks Relating To Raymond James & Associates Equity Securities Ratings. The Fund will seek to construct and maintain a portfolio consisting of the equity securities rated SB-1 by Raymond James & Associates analysts. Changes in the ratings methodologies or in the scope of equity research by Raymond James & Associates may have an adverse effect on the ability of the Fund to pursue its investment strategy.

— There are currently four rating categories used by Raymond James & Associates analysts, with SB-1 being the highest rating. There is no assurance that Raymond James & Associates will continue to use a rating system substantially similar to that currently used by it, or that its highest rating of equity securities will continue to be referenced as “Strong Buy 1.”

— There are no assurances that Raymond James & Associates will continue to provide equity research to the degree currently provided by it, or that it will continue to provide research services at all. Raymond James & Associates may decrease (i) the number of equity analysts that it employs; (ii) the number of covered industries, or (iii) the number of covered issuers within an industry.

— In the event that an analyst leaves Raymond James & Associates, all securities covered by that analyst are placed “under review.” Any such securities included in the Index would be removed during the next rebalancing period, despite the fact that expectations regarding such security’s performance may be unchanged. Following such review, another Raymond James & Associates analyst could subsequently rate such security SB-1; in which event such security would be included in the Index during the next rebalancing period, which would increase portfolio turnover.

— Raymond James & Associates may have published, and in the future may publish, research reports on one or more of the issuers of equity securities rated SB-1. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding such equity securities, notwithstanding the maintenance by Raymond James & Associates of an SB-1 rating on such securities.

— Activities by Raymond James & Associates in other areas of its business, such as underwriting and advisory engagements, may prevent the equity analysts from publishing or updating research on the companies that are the subject of such engagements. Management, legal or compliance personnel of Raymond James & Associates may determine to suspend or restrict research coverage on certain companies from time to time or at any time. The Fund would continue to hold securities that are and continue to be rated SB-1 during the period of such research restrictions, notwithstanding that such securities could be downgraded upon the termination of such restrictions and the publication of current research reports.

— Federal and state securities laws and rules and regulations of the SEC and of other regulatory agencies may prevent an analyst from timely communicating to investors a change in sentiment pertaining to a covered security.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary twice per calendar month, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one and five years and since inception compare with those of the Index and a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available at www.guggenheimfunds.com.

On September 3, 2008, the Fund acquired the assets and adopted the financial and performance history of the Claymore/Raymond James SB-1 Equity Fund (the “Predecessor Fund”). Therefore, the returns provided below also include those of the Predecessor Fund. The investment goals, strategies and policies of the Fund are substantially similar to those of the Predecessor Fund. The performance information provided for the Fund for the period prior to September 3, 2008, is based upon the NAV performance history (not market price) of the Predecessor Fund and reflects the operating expenses of the Predecessor Fund.

Calendar Year Total Return as of 12/31

The Predecessor Fund commenced operations on May 19, 2006. The Fund’s year-to-date return was 11.22% as of September 30, 2012.

During the periods shown in the chart, the Fund’s highest and lowest calendar quarter returns were 25.61% and -29.22%, respectively, for the quarters ended June 30, 2009 and December 31, 2008.

All after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of any state or local tax. Your own actual after-tax returns will depend on your tax situation and may differ from what is shown here. After-tax returns are not relevant to investors who hold Shares of the Fund in tax-deferred accounts such as individual retirement accounts (IRAs) or employee-sponsored retirement plans.

Guggenheim Defensive Equity ETF

Guggenheim Defensive Equity ETF (DEF)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Sabrient Defensive Equity Index (the “Defensive Equity Index” or “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares of the Fund in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Defensive Equity ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		0.35%
Total annual Fund operating expenses		0.85%
Expense reimbursements	[2]	0.20%
Total annual Fund operating expenses after expense reimbursements		0.65%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Defensive Equity ETF	66	262	521	1,261

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Defensive Equity Index (Index Ticker: SBRDETR). As of November 30, 2012, the Index was comprised of approximately 100 securities selected, based on investment and other criteria developed by Sabrient Systems LLC (“Sabrient” or the “Index Provider”), from a broad universe of U.S.-traded securities, including master limited partnerships (“MLPs”) and American depositary receipts (“ADRs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of potential Index constituents includes approximately 1,000 listed companies, generally with market capitalizations in excess of $1 billion. The Fund will invest at least 90% of its total assets in common stock, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Utilities Sector Risk. The rates that traditional regulated utility companies may charge their customers generally are subject to review and limitation by governmental regulatory commissions. Although rate changes of a utility usually fluctuate in approximate correlation with financing costs due to political and regulatory factors, rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable.

Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants; the effects of energy conservation and the effects of regulatory changes.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the BRIC Index (Index Ticker: BKBRICT). The BRIC Index is comprised of American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) selected, based on liquidity, from a universe of all listed depositary receipts of companies from Brazil, Russia, India and China currently trading on U.S. exchanges. The depositary receipts that comprise the Index may be sponsored or unsponsored. The companies in the universe are selected using a proprietary methodology developed by The Bank of New York Mellon (the “Index Provider” or “BNY Mellon”). The Fund will invest at least 90% of its total assets in ADRs and GDRs that comprise the Index and underlying securities representing ADRs and GDRs that comprise the Index. As of November 30, 2012, the Index consisted of 76 securities. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by the depositary receipts comprising the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs and GDRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Brazil has experienced substantial economic instability resulting from, among other things, periods of very high inflation, persistent structural public sector deficits and significant devaluations of the currency of Brazil, and leading also to a high degree of price volatility in both the Brazilian equity and foreign currency markets. Brazilian companies may also be adversely affected by high interest and unemployment rates, and are particularly sensitive to fluctuations in commodity prices.

Investing in securities of Russian companies involves additional risks, including, among others, the absence of developed legal structures governing private or foreign investments and private property; the possibility of the loss of all or a substantial portion of the Fund’s assets invested in Russia as a result of expropriation; certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests; and potentially greater price volatility in, significantly smaller capitalization of, and relative illiquidity of, some of these markets.

Investing in securities of Indian companies involves additional risks, including, but not limited to, greater price volatility, substantially less liquidity and significantly smaller market capitalization of securities markets, more substantial governmental involvement in the economy, higher rates of inflation and greater political, economic and social uncertainty. Furthermore, future actions of the Indian Government or religious and ethnic unrest could have a significant impact on the economy.

Investing in securities of Chinese companies involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, previously the Chinese government has from time to time taken actions that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate in particular industries, induce mergers between companies in certain industries and induce private companies to publicly offer their securities to increase or continue the rate of economic growth, control the rate of inflation or otherwise regulate economic expansion. It may do so in the future as well, potentially having a significant adverse effect on economic conditions in China, the economic prospects for, and the market prices and liquidity of, the securities of China companies and the payments of dividends and interest by China companies.

China Exposure Risk. From time to time, certain of the companies comprising the BNY Mellon BRIC Index that are located in China may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries identified by the U.S. government as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations which could negatively affect the company’s performance, and/or could suffer damage to its reputation if it is identified as a company which invests or deals with countries which are identified by the U.S. government as state sponsors of terrorism or subject to sanctions. As an investor in such companies, the Fund is indirectly subject to those risks.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs and GDRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. GDRs are similar to ADRs, but may be issued in bearer form and are typically offered for sale globally and held by a foreign branch of an international bank. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs and GDRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs and GDRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs and GDRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. The telecommunications sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid obsolescence and research and development of new products. Other risks include those related to regulatory changes, such as the uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ stocks may be more volatile and less liquid than those of larger, more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, or otherwise holds investments other than those which comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Defensive Equity Index (Index Ticker: SBRDETR). As of November 30, 2012, the Index was comprised of approximately 100 securities selected, based on investment and other criteria developed by Sabrient Systems LLC (“Sabrient” or the “Index Provider”), from a broad universe of U.S.-traded securities, including master limited partnerships (“MLPs”) and American depositary receipts (“ADRs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of potential Index constituents includes approximately 1,000 listed companies, generally with market capitalizations in excess of $1 billion. The Fund will invest at least 90% of its total assets in common stock, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Strategy Portfolio Concentration [Text]

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Utilities Sector Risk. The rates that traditional regulated utility companies may charge their customers generally are subject to review and limitation by governmental regulatory commissions. Although rate changes of a utility usually fluctuate in approximate correlation with financing costs due to political and regulatory factors, rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable.

Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants; the effects of energy conservation and the effects of regulatory changes.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Insider Sentiment Index (Index Ticker: SBRINTR). As of November 30, 2012, the Index was comprised of approximately 100 securities selected, based on investment and other criteria developed by Sabrient Systems LLC (“Sabrient” or the “Index Provider”), from a broad universe of U.S.-traded securities, including master limited partnerships (“MLPs”) and American depositary receipts (“ADRs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of companies eligible for inclusion in the Index includes approximately 5,000 listed companies without limitations on market capitalization. The Fund will invest at least 90% of its total assets in common stocks, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

The Fund will invest at least 90% of its total assets in common stocks, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index).

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risk because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Insider Sentiment Index, or otherwise take defensive positions in declining markets.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Zacks Mid-Cap Core Index (Index Ticker: ZAXMC). As of November 30, 2012, the Index was comprised of 100 securities selected, based on investment and other criteria, from a universe of mid-capitalization securities including master limited partnerships (“MLPs”), American depositary receipts (“ADRs”) and business development companies (“BDCs”). The depositary receipts included in the Index may be sponsored or unsponsored. Currently, the mid-capitalization universe ranges from approximately $1 billion in market capitalization to $14 billion in market capitalization as defined by Zacks Investment Research, Inc. (“Zacks” or the “Index Provider”).The securities in the universe are selected using a proprietary strategy developed by Zacks. The Fund will invest at least 90% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Medium-Sized Company Risk. Investing in securities of medium-sized companies involves greater risk than is customarily associated with investing in more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The Investment Company Act of 1940, as amended (the “1940 Act”), imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Zacks Multi-Asset Income Index (Index Ticker: ZAXYHTR). As of November 30, 2012, the Zacks Multi-Asset Income Index was comprised of approximately 149 securities selected, based on investment and other criteria, from a universe of domestic and international companies. The securities comprising the Index include stocks of small and medium-sized companies. The universe of securities within the Index includes U.S. listed common stocks and American depositary receipts (“ADRs”) paying dividends, real estate investment trusts (“REITs”), master limited partnerships (“MLPs”), closed-end funds, Canadian royalty trusts and traditional preferred stocks. The depositary receipts included in the Index may be sponsored or unsponsored. The companies in the universe are selected using a proprietary methodology developed by Zacks Investment Research, Inc. (“Zacks” or the “Index Provider”). The Fund will invest at least 90% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its objective. Sampling means that the Investment Adviser uses quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include industry weightings, market capitalization and other financial characteristics of securities. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Preferred Stock Risk. There are certain additional risks associated with investing in preferred securities, including, but not limited to, (i) preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer; (ii) preferred securities are generally subordinated to bonds and other debt instruments in a company’s capital structure in terms of having priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt instruments; preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. Government securities; generally, traditional preferred securities offer no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board; in certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Canadian Royalty Trust Risk. As the Fund invests in Canadian royalty trusts, it is subject to the following risks applicable to Canadian royalty trusts:

Lack of diversification. The royalty trusts in which the Fund invests are heavily invested in oil and gas.

Potential sacrifice of growth. Potential growth may be sacrificed because revenue is passed on to a royalty trust’s unit holders (such as the Fund), rather than reinvested in the business.

No guarantees. Royalty trusts generally do not guarantee minimum distributions or even return of capital. If the assets underlying a royalty trust do not perform as expected, the royalty trust may reduce or even eliminate distributions. The declaration of such distributions generally depends upon various factors, including the operating performance and financial condition of the royalty trust and general economic conditions.

Potential for tax recharacterization or changes. Under amendments to the Income Tax Act (Canada) passed in 2007 (the “SIFT Rules”), certain trusts (defined as “SIFT trusts”) are taxable on certain income and gains on a basis similar to that which applies to a corporation, with the result that tax efficiencies formerly available in respect of an investment in the trust may cease to be available. A royalty trust may be a SIFT trust. In addition, as a result of the SIFT Rules, some trusts may undertake reorganization transactions, the costs of which may affect the return earned on an investment in the trust. After any such conversion, tax efficiencies that were formerly available in respect of an investment in the trust may cease to be available. Accordingly, the SIFT Rules have had and may continue to have an effect on the trading price of investments in royalty trusts, and consequently could impact the value of Shares of the Fund.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ stocks may be more volatile and less liquid than those of larger, more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market.

Below-Investment Grade Securities Risk. The Fund may invest in certain preferred stocks that are rated below investment grade. Preferred stocks that are not investment grade are high yield, high risk securities. These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative by the major credit rating agencies. Preferred stocks rated below investment grade may be issued by companies that are restructuring, are smaller and less creditworthy, or are more highly indebted than other companies. This means that they may have more difficulty making scheduled dividend payments. Changes in the value of preferred stocks rated below investment grade are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade preferred stocks.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund  utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the SB-1 Equity Index (Index Ticker: RJSBITR). The SB-1 Equity Index is composed of all equity securities rated Strong Buy 1 (“SB-1”) by Raymond James & Associates, Inc. (“Raymond James & Associates”), an affiliate of Raymond James Research Services, LLC (“Raymond James” or the “Index Provider”), as of each rebalance and reconstitution date. Index constituents include equity securities of all market capitalizations, as defined by the Index Provider, that trade on a U.S. securities exchange, including common stocks, American depositary receipts (“ADRs”), real estate investment trusts (“REITs”) and master limited partnerships (“MLPs”). The depositary receipts included in the Index may be sponsored or unsponsored. The number of securities in the Index may vary depending on the number of equity securities rated SB-1 by Raymond James & Associates. The Index generally consists of between 100 and 200 securities and, as of November 30, 2012, the market capitalization range of Index constituents was $24 million to $1 billion. Under normal conditions, the Fund will invest at least 80% of its assets in equity securities. The Fund will invest at least 80% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust (the "Board of Trustees")  may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the total return of the Index less any expenses or distributions. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Risk [Heading]

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

Concentration Risk. At any given time, the Fund may invest a substantial portion of its assets in the securities of issuers in any single sector of the economy and may invest up to 25% of its total assets in securities of issuers in one particular industry, and may invest more than 25% of its total assets in securities of issuers in one particular industry in the event that the composition of the issuers of securities rated SB-1 on a rebalancing day results in such an industry concentration in the Index. If the Fund’s investments are focused in a specific industry or sector, the Fund will be subject to more risks, including those risks associated with investment in such industry or sector, than if it were broadly diversified over numerous industries and sectors of the economy.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks Relating To Raymond James & Associates Equity Securities Ratings. The Fund will seek to construct and maintain a portfolio consisting of the equity securities rated SB-1 by Raymond James & Associates analysts. Changes in the ratings methodologies or in the scope of equity research by Raymond James & Associates may have an adverse effect on the ability of the Fund to pursue its investment strategy.

— There are currently four rating categories used by Raymond James & Associates analysts, with SB-1 being the highest rating. There is no assurance that Raymond James & Associates will continue to use a rating system substantially similar to that currently used by it, or that its highest rating of equity securities will continue to be referenced as “Strong Buy 1.”

— There are no assurances that Raymond James & Associates will continue to provide equity research to the degree currently provided by it, or that it will continue to provide research services at all. Raymond James & Associates may decrease (i) the number of equity analysts that it employs; (ii) the number of covered industries, or (iii) the number of covered issuers within an industry.

— In the event that an analyst leaves Raymond James & Associates, all securities covered by that analyst are placed “under review.” Any such securities included in the Index would be removed during the next rebalancing period, despite the fact that expectations regarding such security’s performance may be unchanged. Following such review, another Raymond James & Associates analyst could subsequently rate such security SB-1; in which event such security would be included in the Index during the next rebalancing period, which would increase portfolio turnover.

— Raymond James & Associates may have published, and in the future may publish, research reports on one or more of the issuers of equity securities rated SB-1. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding such equity securities, notwithstanding the maintenance by Raymond James & Associates of an SB-1 rating on such securities.

— Activities by Raymond James & Associates in other areas of its business, such as underwriting and advisory engagements, may prevent the equity analysts from publishing or updating research on the companies that are the subject of such engagements. Management, legal or compliance personnel of Raymond James & Associates may determine to suspend or restrict research coverage on certain companies from time to time or at any time. The Fund would continue to hold securities that are and continue to be rated SB-1 during the period of such research restrictions, notwithstanding that such securities could be downgraded upon the termination of such restrictions and the publication of current research reports.

— Federal and state securities laws and rules and regulations of the SEC and of other regulatory agencies may prevent an analyst from timely communicating to investors a change in sentiment pertaining to a covered security.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary twice per calendar month, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Spin-off Index (Index Ticker: CLRSOTR). As of November 30, 2012, the Spin-off Index was comprised of approximately 24 securities selected, based on investment and other criteria, from a broad universe of U.S.-traded stocks, American depositary receipts (“ADRs”) and master limited partnerships (“MLPs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of companies eligible for inclusion in the Index includes companies that have been spun-off within the past 30 months (but not more recently than six months prior to the applicable rebalancing date), without limitations on market capitalization (including micro-cap securities), but which are primarily small- and mid-cap companies with capitalizations under $10.0 billion. The time period from being spun-off may be extended to compensate for periods where there are too few new spin-offs to populate the Index. Beacon Indexes LLC (“Beacon” or the “Index Provider”) defines a spin-off company as any company resulting from either of the following events: a spin-off distribution of stock of a subsidiary company by its parent company to parent company shareholders or equity “carve-outs” or “partial initial public offerings” in which a parent company sells a percentage of the equity of a subsidiary to public shareholders. The Fund will invest at least 90% of its total assets in common stock, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Strategy Portfolio Concentration [Text]

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Industrial Sector Risk. The stock prices of companies in the industrial sector are affected by supply and demand both for their specific product or service and for industrial sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulation, world events and economic conditions may affect the performance of companies in the industrial sector. Companies in the industrial sector may be at risk for environmental damage and product liability claims.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. The telecommunications sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid obsolescence and research and development of new products. Other risks include those related to regulatory changes, such as the uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or futures or other derivative positions, or otherwise holds investments other than those which comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire 4500 (Index Ticker: W4500). The Wilshire 4500 is a rules-based index comprised of, as of November 30, 2012, approximately 3,218 securities of U.S. issuers, including common stocks, real estate investment trusts (“REITs”) and business development companies (“BDCs”). The Index may include securities of companies of all categories of market capitalizations (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire 4500 is a subset of the Wilshire 5000 Total Market IndexSM (the “Wilshire 5000”). Designed to represent the extended market, the Wilshire 4500 is the Wilshire 5000 with the components of the S&P 500 Index® excluded.

The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire 4500. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire 4500. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser and Investment Sub-Adviser use quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The 1940 Act, imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund utilizes a sampling approach (or if it otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire 5000 (Index Ticker: W5000FLT). The Wilshire 5000 is a rules-based index comprised of, as of November 30, 2012, approximately 3,707 securities, including common stocks and real estate investment trusts (“REITs”). The Index may include securities of companies of all categories of market capitalizations (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire 5000 is designed to represent the total U.S. equity market and includes all U.S. equity securities that have readily available prices. The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire 5000. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire 5000. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser and Investment Sub-Adviser use quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser or Investment Sub-Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser or Investment Sub-Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund utilizes a sampling approach (or if it otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly, In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

The Fund, using a low cost “passive” or “indexing” investment approach, will seek to replicate, before the Fund’s fees and expenses, the performance of the Wilshire Micro-Cap (Index Ticker: W5KMICRO). The Wilshire Micro-Cap is a rules-based index comprised of, as of November 30, 2012, approximately 1,195 securities of micro-capitalization companies, including real estate investment trusts (“REITs”) and business development companies (“BDCs”), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire Micro-Cap is designed to represent micro-sized companies and is a subset of the Wilshire 5000 Total Market IndexSM (the “Wilshire 5000”). The Wilshire Micro-Cap represents a float-adjusted, market capitalization-weighted index of the issues ranked below 2500 by market capitalization of the Wilshire 5000. Under normal conditions, the Fund will invest at least 80% of its total assets in securities of micro-capitalization companies. In addition, the Fund will invest at least 80% of its total assets in equity securities that comprise the Index. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund.

Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when a Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing return to the Fund on its investment in such company.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The 1940 Act, imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Small Company Risk. Certain of the companies in which the Fund may invest may at times be considered small-capitalization, rather than micro-capitalization, companies. Investing in securities of small companies involves greater risk than is customarily associated with investing in more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. As the Fund utilizes a sampling approach (and/or if the Fund otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire US REIT (Index Ticker: WILREIT). The Wilshire US REIT is a rules-based index comprised of, as of November 30, 2012, approximately 102 securities, which may include securities of companies of all categories of market capitalizations, (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire US REIT is comprised primarily of real estate investment trusts (“REITs”) and is derived from the broader Wilshire 5000 Total Market IndexSM. The Wilshire US REIT is weighted by float-adjusted market capitalization. The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire US REIT. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire US REIT. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions (such as the turmoil experienced since 2007 in the residential and commercial real estate markets); obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company. REITs are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures.

Concentration Risk. Real estate companies may lack diversification due to ownership of a limited number of properties and concentration in a particular geographic region or property type.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for real estate companies, which could negatively impact a real estate company’s ability to meet its payment obligations.

Leverage Risk. Real estate companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing and could adversely affect a real estate company’s operations and market value in periods of rising interest rates. Financial covenants related to a real estate company’s leveraging may affect the ability of the real estate company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a real estate company to make payments of any interest and principal on its debt securities will be adversely affected. These risks are especially applicable in conditions of declining real estate values, such as those experienced since 2007.

Liquidity Risk. Real estate is relatively illiquid and, therefore, a real estate company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions. These risks are especially applicable in conditions of declining real estate values, such as those experienced since 2007.

Management Risk. Real estate companies are dependent upon management skills and may have limited financial resources. Real estate companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between real estate companies and their affiliates may be subject to conflicts of interest, which may adversely affect a real estate company’s shareholders. A real estate company may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

Property Risk. Real estate companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.

Repayment Risk. The prices of real estate company securities may drop because of the failure of borrowers to repay their loans, poor management, and the inability to obtain financing either on favorable terms or at all. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the real estate company to make payments of interest and principal on their loans will be adversely affected. Many real estate companies utilize leverage, which increases investment risk and could adversely affect a company’s operations and market value in periods of rising interest rates.

Small and Medium-Sized Company Risk. Investing in real estate companies may involve risks similar to those associated with investing in small or medium-sized capitalization companies. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap companies involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or otherwise holds investments other than those that comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees of Claymore Exchange-Traded Fund Trust (the "Trust") has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

Guggenheim Insider Sentiment ETF

Guggenheim Insider Sentiment ETF (NFO)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Sabrient Insider Sentiment Index (the “Insider Sentiment Index” or “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Insider Sentiment ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		0.28%
Total annual Fund operating expenses		0.78%
Expense reimbursements	[2]	0.13%
Total annual Fund operating expenses after expense reimbursements		0.65%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Insider Sentiment ETF	66	262	504	1,199

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 89% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Insider Sentiment Index (Index Ticker: SBRINTR). As of November 30, 2012, the Index was comprised of approximately 100 securities selected, based on investment and other criteria developed by Sabrient Systems LLC (“Sabrient” or the “Index Provider”), from a broad universe of U.S.-traded securities, including master limited partnerships (“MLPs”) and American depositary receipts (“ADRs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of companies eligible for inclusion in the Index includes approximately 5,000 listed companies without limitations on market capitalization. The Fund will invest at least 90% of its total assets in common stocks, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risk because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Insider Sentiment Index, or otherwise take defensive positions in declining markets.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one and five years and since inception compare with those of the Index and a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available at www.guggenheimfunds.com.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire US REIT (Index Ticker: WILREIT). The Wilshire US REIT is a rules-based index comprised of, as of November 30, 2012, approximately 102 securities, which may include securities of companies of all categories of market capitalizations, (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire US REIT is comprised primarily of real estate investment trusts (“REITs”) and is derived from the broader Wilshire 5000 Total Market IndexSM. The Wilshire US REIT is weighted by float-adjusted market capitalization. The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire US REIT. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire US REIT. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions (such as the turmoil experienced since 2007 in the residential and commercial real estate markets); obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company. REITs are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures.

Concentration Risk. Real estate companies may lack diversification due to ownership of a limited number of properties and concentration in a particular geographic region or property type.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for real estate companies, which could negatively impact a real estate company’s ability to meet its payment obligations.

Leverage Risk. Real estate companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing and could adversely affect a real estate company’s operations and market value in periods of rising interest rates. Financial covenants related to a real estate company’s leveraging may affect the ability of the real estate company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a real estate company to make payments of any interest and principal on its debt securities will be adversely affected. These risks are especially applicable in conditions of declining real estate values, such as those experienced since 2007.

Liquidity Risk. Real estate is relatively illiquid and, therefore, a real estate company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions. These risks are especially applicable in conditions of declining real estate values, such as those experienced since 2007.

Management Risk. Real estate companies are dependent upon management skills and may have limited financial resources. Real estate companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between real estate companies and their affiliates may be subject to conflicts of interest, which may adversely affect a real estate company’s shareholders. A real estate company may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

Property Risk. Real estate companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.

Repayment Risk. The prices of real estate company securities may drop because of the failure of borrowers to repay their loans, poor management, and the inability to obtain financing either on favorable terms or at all. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the real estate company to make payments of interest and principal on their loans will be adversely affected. Many real estate companies utilize leverage, which increases investment risk and could adversely affect a company’s operations and market value in periods of rising interest rates.

Small and Medium-Sized Company Risk. Investing in real estate companies may involve risks similar to those associated with investing in small or medium-sized capitalization companies. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap companies involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or otherwise holds investments other than those that comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Wilshire Micro-Cap ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Acquired Fund Fees and Expenses	[2]	0.08%
Total annual Fund operating expenses		0.58%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Wilshire Micro-Cap ETF	59	240	436	1,002

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, will seek to replicate, before the Fund’s fees and expenses, the performance of the Wilshire Micro-Cap (Index Ticker: W5KMICRO). The Wilshire Micro-Cap is a rules-based index comprised of, as of November 30, 2012, approximately 1,195 securities of micro-capitalization companies, including real estate investment trusts (“REITs”) and business development companies (“BDCs”), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire Micro-Cap is designed to represent micro-sized companies and is a subset of the Wilshire 5000 Total Market IndexSM (the “Wilshire 5000”). The Wilshire Micro-Cap represents a float-adjusted, market capitalization-weighted index of the issues ranked below 2500 by market capitalization of the Wilshire 5000. Under normal conditions, the Fund will invest at least 80% of its total assets in securities of micro-capitalization companies. In addition, the Fund will invest at least 80% of its total assets in equity securities that comprise the Index. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser uses quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when a Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing return to the Fund on its investment in such company.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The 1940 Act, imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Small Company Risk. Certain of the companies in which the Fund may invest may at times be considered small-capitalization, rather than micro-capitalization, companies. Investing in securities of small companies involves greater risk than is customarily associated with investing in more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. As the Fund utilizes a sampling approach (and/or if the Fund otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one and five years and since inception compare with those of the Index and broad measures of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Updated performance information for the Fund is available at www.guggenheimfunds.com.

Guggenheim BRIC ETF

Guggenheim BRIC ETF (EEB)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called BNY Mellon BRIC Select ADR Index (the “BRIC Index” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker. 

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim BRIC ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		0.16%
Total annual Fund operating expenses		0.66%
Expense reimbursements	[2]	0.02%
Total annual Fund operating expenses after expense reimbursements		0.64%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim BRIC ETF	65	259	473	1,091

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the BRIC Index (Index Ticker: BKBRICT). The BRIC Index is comprised of American depositary receipts (“ADRs”) and global depositary receipts (“GDRs”) selected, based on liquidity, from a universe of all listed depositary receipts of companies from Brazil, Russia, India and China currently trading on U.S. exchanges. The depositary receipts that comprise the Index may be sponsored or unsponsored. The companies in the universe are selected using a proprietary methodology developed by The Bank of New York Mellon (the “Index Provider” or “BNY Mellon”). The Fund will invest at least 90% of its total assets in ADRs and GDRs that comprise the Index and underlying securities representing ADRs and GDRs that comprise the Index. As of November 30, 2012, the Index consisted of 76 securities. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by the depositary receipts comprising the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs and GDRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Brazil has experienced substantial economic instability resulting from, among other things, periods of very high inflation, persistent structural public sector deficits and significant devaluations of the currency of Brazil, and leading also to a high degree of price volatility in both the Brazilian equity and foreign currency markets. Brazilian companies may also be adversely affected by high interest and unemployment rates, and are particularly sensitive to fluctuations in commodity prices.

Investing in securities of Russian companies involves additional risks, including, among others, the absence of developed legal structures governing private or foreign investments and private property; the possibility of the loss of all or a substantial portion of the Fund’s assets invested in Russia as a result of expropriation; certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests; and potentially greater price volatility in, significantly smaller capitalization of, and relative illiquidity of, some of these markets.

Investing in securities of Indian companies involves additional risks, including, but not limited to, greater price volatility, substantially less liquidity and significantly smaller market capitalization of securities markets, more substantial governmental involvement in the economy, higher rates of inflation and greater political, economic and social uncertainty. Furthermore, future actions of the Indian Government or religious and ethnic unrest could have a significant impact on the economy.

Investing in securities of Chinese companies involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, previously the Chinese government has from time to time taken actions that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate in particular industries, induce mergers between companies in certain industries and induce private companies to publicly offer their securities to increase or continue the rate of economic growth, control the rate of inflation or otherwise regulate economic expansion. It may do so in the future as well, potentially having a significant adverse effect on economic conditions in China, the economic prospects for, and the market prices and liquidity of, the securities of China companies and the payments of dividends and interest by China companies.

China Exposure Risk. From time to time, certain of the companies comprising the BNY Mellon BRIC Index that are located in China may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries identified by the U.S. government as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations which could negatively affect the company’s performance, and/or could suffer damage to its reputation if it is identified as a company which invests or deals with countries which are identified by the U.S. government as state sponsors of terrorism or subject to sanctions. As an investor in such companies, the Fund is indirectly subject to those risks.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs and GDRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. GDRs are similar to ADRs, but may be issued in bearer form and are typically offered for sale globally and held by a foreign branch of an international bank. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs and GDRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs and GDRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs and GDRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. The telecommunications sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid obsolescence and research and development of new products. Other risks include those related to regulatory changes, such as the uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ stocks may be more volatile and less liquid than those of larger, more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, or otherwise holds investments other than those which comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one and five years and since inception compare with those of the Index and a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available at www.guggenheimfunds.com.

Calendar Year Total Return as of 12/31

The Fund commenced operations on September 21, 2006. The Fund’s year-to-date return was 1.17% as of September 30, 2012.

Guggenheim Defensive Equity ETF

Guggenheim Defensive Equity ETF (DEF)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Sabrient Defensive Equity Index (the “Defensive Equity Index” or “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares of the Fund in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Defensive Equity ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		0.35%
Total annual Fund operating expenses		0.85%
Expense reimbursements	[2]	0.20%
Total annual Fund operating expenses after expense reimbursements		0.65%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Defensive Equity ETF	66	262	521	1,261

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Defensive Equity Index (Index Ticker: SBRDETR). As of November 30, 2012, the Index was comprised of approximately 100 securities selected, based on investment and other criteria developed by Sabrient Systems LLC (“Sabrient” or the “Index Provider”), from a broad universe of U.S.-traded securities, including master limited partnerships (“MLPs”) and American depositary receipts (“ADRs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of potential Index constituents includes approximately 1,000 listed companies, generally with market capitalizations in excess of $1 billion. The Fund will invest at least 90% of its total assets in common stock, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Utilities Sector Risk. The rates that traditional regulated utility companies may charge their customers generally are subject to review and limitation by governmental regulatory commissions. Although rate changes of a utility usually fluctuate in approximate correlation with financing costs due to political and regulatory factors, rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable.

Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants; the effects of energy conservation and the effects of regulatory changes.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 89% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Insider Sentiment Index (Index Ticker: SBRINTR). As of November 30, 2012, the Index was comprised of approximately 100 securities selected, based on investment and other criteria developed by Sabrient Systems LLC (“Sabrient” or the “Index Provider”), from a broad universe of U.S.-traded securities, including master limited partnerships (“MLPs”) and American depositary receipts (“ADRs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of companies eligible for inclusion in the Index includes approximately 5,000 listed companies without limitations on market capitalization. The Fund will invest at least 90% of its total assets in common stocks, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risk because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Insider Sentiment Index, or otherwise take defensive positions in declining markets.

Guggenheim Mid-Cap Core ETF

Guggenheim Mid-Cap Core ETF (CZA)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an index called the Zacks Mid-Cap Core Index (the “Zacks Mid-Cap Core Index” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Mid-Cap Core ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		0.51%
Total annual Fund operating expenses		1.01%
Expense reimbursements	[2]	0.36%
Total annual Fund operating expenses after expense reimbursements		0.65%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Mid-Cap Core ETF	66	262	558	1,399

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Zacks Mid-Cap Core Index (Index Ticker: ZAXMC). As of November 30, 2012, the Index was comprised of 100 securities selected, based on investment and other criteria, from a universe of mid-capitalization securities including master limited partnerships (“MLPs”), American depositary receipts (“ADRs”) and business development companies (“BDCs”). The depositary receipts included in the Index may be sponsored or unsponsored. Currently, the mid-capitalization universe ranges from approximately $1 billion in market capitalization to $14 billion in market capitalization as defined by Zacks Investment Research, Inc. (“Zacks” or the “Index Provider”).The securities in the universe are selected using a proprietary strategy developed by Zacks. The Fund will invest at least 90% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Medium-Sized Company Risk. Investing in securities of medium-sized companies involves greater risk than is customarily associated with investing in more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The Investment Company Act of 1940, as amended (the “1940 Act”), imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one year and since inception compare with those of the Index and broad measures of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 113% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Zacks Multi-Asset Income Index (Index Ticker: ZAXYHTR). As of November 30, 2012, the Zacks Multi-Asset Income Index was comprised of approximately 149 securities selected, based on investment and other criteria, from a universe of domestic and international companies. The securities comprising the Index include stocks of small and medium-sized companies. The universe of securities within the Index includes U.S. listed common stocks and American depositary receipts (“ADRs”) paying dividends, real estate investment trusts (“REITs”), master limited partnerships (“MLPs”), closed-end funds, Canadian royalty trusts and traditional preferred stocks. The depositary receipts included in the Index may be sponsored or unsponsored. The companies in the universe are selected using a proprietary methodology developed by Zacks Investment Research, Inc. (“Zacks” or the “Index Provider”). The Fund will invest at least 90% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its objective. Sampling means that the Investment Adviser uses quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include industry weightings, market capitalization and other financial characteristics of securities. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Preferred Stock Risk. There are certain additional risks associated with investing in preferred securities, including, but not limited to, (i) preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer; (ii) preferred securities are generally subordinated to bonds and other debt instruments in a company’s capital structure in terms of having priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt instruments; preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. Government securities; generally, traditional preferred securities offer no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board; in certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Canadian Royalty Trust Risk. As the Fund invests in Canadian royalty trusts, it is subject to the following risks applicable to Canadian royalty trusts:

Lack of diversification. The royalty trusts in which the Fund invests are heavily invested in oil and gas.

Potential sacrifice of growth. Potential growth may be sacrificed because revenue is passed on to a royalty trust’s unit holders (such as the Fund), rather than reinvested in the business.

No guarantees. Royalty trusts generally do not guarantee minimum distributions or even return of capital. If the assets underlying a royalty trust do not perform as expected, the royalty trust may reduce or even eliminate distributions. The declaration of such distributions generally depends upon various factors, including the operating performance and financial condition of the royalty trust and general economic conditions.

Potential for tax recharacterization or changes. Under amendments to the Income Tax Act (Canada) passed in 2007 (the “SIFT Rules”), certain trusts (defined as “SIFT trusts”) are taxable on certain income and gains on a basis similar to that which applies to a corporation, with the result that tax efficiencies formerly available in respect of an investment in the trust may cease to be available. A royalty trust may be a SIFT trust. In addition, as a result of the SIFT Rules, some trusts may undertake reorganization transactions, the costs of which may affect the return earned on an investment in the trust. After any such conversion, tax efficiencies that were formerly available in respect of an investment in the trust may cease to be available. Accordingly, the SIFT Rules have had and may continue to have an effect on the trading price of investments in royalty trusts, and consequently could impact the value of Shares of the Fund.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ stocks may be more volatile and less liquid than those of larger, more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market.

Below-Investment Grade Securities Risk. The Fund may invest in certain preferred stocks that are rated below investment grade. Preferred stocks that are not investment grade are high yield, high risk securities. These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative by the major credit rating agencies. Preferred stocks rated below investment grade may be issued by companies that are restructuring, are smaller and less creditworthy, or are more highly indebted than other companies. This means that they may have more difficulty making scheduled dividend payments. Changes in the value of preferred stocks rated below investment grade are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade preferred stocks.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund  utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one and five years and since inception compare with those of the Index and broad measures of market performance.

Guggenheim Raymond James SB-1 Equity ETF

Guggenheim Raymond James SB-1 Equity ETF (RYJ)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Raymond James SB-1 Equity Index (the “SB-1 Equity Index” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Raymond James SB-1 Equity ETF
Management fees		0.75%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Total annual Fund operating expenses		0.75%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Raymond James SB-1 Equity ETF	77	294	528	1,202

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the SB-1 Equity Index (Index Ticker: RJSBITR). The SB-1 Equity Index is composed of all equity securities rated Strong Buy 1 (“SB-1”) by Raymond James & Associates, Inc. (“Raymond James & Associates”), an affiliate of Raymond James Research Services, LLC (“Raymond James” or the “Index Provider”), as of each rebalance and reconstitution date. Index constituents include equity securities of all market capitalizations, as defined by the Index Provider, that trade on a U.S. securities exchange, including common stocks, American depositary receipts (“ADRs”), real estate investment trusts (“REITs”) and master limited partnerships (“MLPs”). The depositary receipts included in the Index may be sponsored or unsponsored. The number of securities in the Index may vary depending on the number of equity securities rated SB-1 by Raymond James & Associates. The Index generally consists of between 100 and 200 securities and, as of November 30, 2012, the market capitalization range of Index constituents was $24 million to $1 billion. Under normal conditions, the Fund will invest at least 80% of its assets in equity securities. The Fund will invest at least 80% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust (the "Board of Trustees")  may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the total return of the Index less any expenses or distributions. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

Concentration Risk. At any given time, the Fund may invest a substantial portion of its assets in the securities of issuers in any single sector of the economy and may invest up to 25% of its total assets in securities of issuers in one particular industry, and may invest more than 25% of its total assets in securities of issuers in one particular industry in the event that the composition of the issuers of securities rated SB-1 on a rebalancing day results in such an industry concentration in the Index. If the Fund’s investments are focused in a specific industry or sector, the Fund will be subject to more risks, including those risks associated with investment in such industry or sector, than if it were broadly diversified over numerous industries and sectors of the economy.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks Relating To Raymond James & Associates Equity Securities Ratings. The Fund will seek to construct and maintain a portfolio consisting of the equity securities rated SB-1 by Raymond James & Associates analysts. Changes in the ratings methodologies or in the scope of equity research by Raymond James & Associates may have an adverse effect on the ability of the Fund to pursue its investment strategy.

— There are currently four rating categories used by Raymond James & Associates analysts, with SB-1 being the highest rating. There is no assurance that Raymond James & Associates will continue to use a rating system substantially similar to that currently used by it, or that its highest rating of equity securities will continue to be referenced as “Strong Buy 1.”

— There are no assurances that Raymond James & Associates will continue to provide equity research to the degree currently provided by it, or that it will continue to provide research services at all. Raymond James & Associates may decrease (i) the number of equity analysts that it employs; (ii) the number of covered industries, or (iii) the number of covered issuers within an industry.

— In the event that an analyst leaves Raymond James & Associates, all securities covered by that analyst are placed “under review.” Any such securities included in the Index would be removed during the next rebalancing period, despite the fact that expectations regarding such security’s performance may be unchanged. Following such review, another Raymond James & Associates analyst could subsequently rate such security SB-1; in which event such security would be included in the Index during the next rebalancing period, which would increase portfolio turnover.

— Raymond James & Associates may have published, and in the future may publish, research reports on one or more of the issuers of equity securities rated SB-1. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding such equity securities, notwithstanding the maintenance by Raymond James & Associates of an SB-1 rating on such securities.

— Activities by Raymond James & Associates in other areas of its business, such as underwriting and advisory engagements, may prevent the equity analysts from publishing or updating research on the companies that are the subject of such engagements. Management, legal or compliance personnel of Raymond James & Associates may determine to suspend or restrict research coverage on certain companies from time to time or at any time. The Fund would continue to hold securities that are and continue to be rated SB-1 during the period of such research restrictions, notwithstanding that such securities could be downgraded upon the termination of such restrictions and the publication of current research reports.

— Federal and state securities laws and rules and regulations of the SEC and of other regulatory agencies may prevent an analyst from timely communicating to investors a change in sentiment pertaining to a covered security.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary twice per calendar month, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one and five years and since inception compare with those of the Index and a broad measure of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available at www.guggenheimfunds.com.

On September 3, 2008, the Fund acquired the assets and adopted the financial and performance history of the Claymore/Raymond James SB-1 Equity Fund (the “Predecessor Fund”). Therefore, the returns provided below also include those of the Predecessor Fund. The investment goals, strategies and policies of the Fund are substantially similar to those of the Predecessor Fund. The performance information provided for the Fund for the period prior to September 3, 2008, is based upon the NAV performance history (not market price) of the Predecessor Fund and reflects the operating expenses of the Predecessor Fund.

Calendar Year Total Return as of 12/31

The Predecessor Fund commenced operations on May 19, 2006. The Fund’s year-to-date return was 11.22% as of September 30, 2012.

During the periods shown in the chart, the Fund’s highest and lowest calendar quarter returns were 25.61% and -29.22%, respectively, for the quarters ended June 30, 2009 and December 31, 2008.

Guggenheim Spin-Off ETF

Guggenheim Spin-Off ETF (CSD)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Beacon Spin-off Index (the “Spin-off Index” or “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Spin-Off ETF	66	262	560	1,408

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 77% of the average value of its portfolio

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Spin-off Index (Index Ticker: CLRSOTR). As of November 30, 2012, the Spin-off Index was comprised of approximately 24 securities selected, based on investment and other criteria, from a broad universe of U.S.-traded stocks, American depositary receipts (“ADRs”) and master limited partnerships (“MLPs”). The depositary receipts included in the Index may be sponsored or unsponsored. The universe of companies eligible for inclusion in the Index includes companies that have been spun-off within the past 30 months (but not more recently than six months prior to the applicable rebalancing date), without limitations on market capitalization (including micro-cap securities), but which are primarily small- and mid-cap companies with capitalizations under $10.0 billion. The time period from being spun-off may be extended to compensate for periods where there are too few new spin-offs to populate the Index. Beacon Indexes LLC (“Beacon” or the “Index Provider”) defines a spin-off company as any company resulting from either of the following events: a spin-off distribution of stock of a subsidiary company by its parent company to parent company shareholders or equity “carve-outs” or “partial initial public offerings” in which a parent company sells a percentage of the equity of a subsidiary to public shareholders. The Fund will invest at least 90% of its total assets in common stock, ADRs and MLPs that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Industrial Sector Risk. The stock prices of companies in the industrial sector are affected by supply and demand both for their specific product or service and for industrial sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulation, world events and economic conditions may affect the performance of companies in the industrial sector. Companies in the industrial sector may be at risk for environmental damage and product liability claims.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. The telecommunications sector can also be significantly affected by intense competition, including competition with alternative technologies such as wireless communications, product compatibility, consumer preferences, rapid obsolescence and research and development of new products. Other risks include those related to regulatory changes, such as the uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or futures or other derivative positions, or otherwise holds investments other than those which comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Fund Performance

Wilshire 4500 Completion ETF

Wilshire 4500 Completion ETF (WXSP)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Wilshire 4500 Completion Index^SM (the “Wilshire 4500” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Wilshire 4500 Completion ETF
Management fees		0.18%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Acquired Fund Fees and Expenses	[2]	0.02%
Total annual Fund operating expenses		0.20%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Wilshire 4500 Completion ETF	20	119	227	543

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the Fund’s fiscal year ended August 31, 2012, the Fund’s portfolio turnover rate was 15% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire 4500 (Index Ticker: W4500). The Wilshire 4500 is a rules-based index comprised of, as of November 30, 2012, approximately 3,218 securities of U.S. issuers, including common stocks, real estate investment trusts (“REITs”) and business development companies (“BDCs”). The Index may include securities of companies of all categories of market capitalizations (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire 4500 is a subset of the Wilshire 5000 Total Market IndexSM (the “Wilshire 5000”). Designed to represent the extended market, the Wilshire 4500 is the Wilshire 5000 with the components of the S&P 500 Index® excluded.

The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire 4500. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire 4500. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser and Investment Sub-Adviser use quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The 1940 Act, imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund utilizes a sampling approach (or if it otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries, the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Wilshire 5000 Total Market ETF	12	94	182	443

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire 5000 (Index Ticker: W5000FLT). The Wilshire 5000 is a rules-based index comprised of, as of November 30, 2012, approximately 3,707 securities, including common stocks and real estate investment trusts (“REITs”). The Index may include securities of companies of all categories of market capitalizations (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire 5000 is designed to represent the total U.S. equity market and includes all U.S. equity securities that have readily available prices. The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire 5000. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire 5000. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser and Investment Sub-Adviser use quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser or Investment Sub-Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser or Investment Sub-Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund utilizes a sampling approach (or if it otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly, In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one year and since inception compare with those of the Index and a broad measure of market performance.

Wilshire Micro-Cap ETF

Wilshire Micro-Cap ETF (WMCR)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Wilshire US Micro-Cap Index^SM (the “Wilshire Micro-Cap” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Wilshire Micro-Cap ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Acquired Fund Fees and Expenses	[2]	0.08%
Total annual Fund operating expenses		0.58%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Wilshire Micro-Cap ETF	59	240	436	1,002

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, will seek to replicate, before the Fund’s fees and expenses, the performance of the Wilshire Micro-Cap (Index Ticker: W5KMICRO). The Wilshire Micro-Cap is a rules-based index comprised of, as of November 30, 2012, approximately 1,195 securities of micro-capitalization companies, including real estate investment trusts (“REITs”) and business development companies (“BDCs”), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire Micro-Cap is designed to represent micro-sized companies and is a subset of the Wilshire 5000 Total Market IndexSM (the “Wilshire 5000”). The Wilshire Micro-Cap represents a float-adjusted, market capitalization-weighted index of the issues ranked below 2500 by market capitalization of the Wilshire 5000. Under normal conditions, the Fund will invest at least 80% of its total assets in securities of micro-capitalization companies. In addition, the Fund will invest at least 80% of its total assets in equity securities that comprise the Index. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser uses quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because, the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when a Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for a Fund, including significantly reducing return to the Fund on its investment in such company.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The 1940 Act, imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Small Company Risk. Certain of the companies in which the Fund may invest may at times be considered small-capitalization, rather than micro-capitalization, companies. Investing in securities of small companies involves greater risk than is customarily associated with investing in more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. As the Fund utilizes a sampling approach (and/or if the Fund otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire US REIT (Index Ticker: WILREIT). The Wilshire US REIT is a rules-based index comprised of, as of November 30, 2012, approximately 102 securities, which may include securities of companies of all categories of market capitalizations, (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire US REIT is comprised primarily of real estate investment trusts (“REITs”) and is derived from the broader Wilshire 5000 Total Market IndexSM. The Wilshire US REIT is weighted by float-adjusted market capitalization. The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire US REIT. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire US REIT. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions (such as the turmoil experienced since 2007 in the residential and commercial real estate markets); obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company. REITs are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures.

Concentration Risk. Real estate companies may lack diversification due to ownership of a limited number of properties and concentration in a particular geographic region or property type.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for real estate companies, which could negatively impact a real estate company’s ability to meet its payment obligations.

Leverage Risk. Real estate companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing and could adversely affect a real estate company’s operations and market value in periods of rising interest rates. Financial covenants related to a real estate company’s leveraging may affect the ability of the real estate company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a real estate company to make payments of any interest and principal on its debt securities will be adversely affected. These risks are especially applicable in conditions of declining real estate values, such as those experienced since 2007.

Liquidity Risk. Real estate is relatively illiquid and, therefore, a real estate company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions. These risks are especially applicable in conditions of declining real estate values, such as those experienced since 2007.

Management Risk. Real estate companies are dependent upon management skills and may have limited financial resources. Real estate companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between real estate companies and their affiliates may be subject to conflicts of interest, which may adversely affect a real estate company’s shareholders. A real estate company may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

Property Risk. Real estate companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.

Repayment Risk. The prices of real estate company securities may drop because of the failure of borrowers to repay their loans, poor management, and the inability to obtain financing either on favorable terms or at all. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the real estate company to make payments of interest and principal on their loans will be adversely affected. Many real estate companies utilize leverage, which increases investment risk and could adversely affect a company’s operations and market value in periods of rising interest rates.

Small and Medium-Sized Company Risk. Investing in real estate companies may involve risks similar to those associated with investing in small or medium-sized capitalization companies. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap companies involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or otherwise holds investments other than those that comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.

Fund Performance

Guggenheim Mid-Cap Core ETF

Guggenheim Mid-Cap Core ETF (CZA)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an index called the Zacks Mid-Cap Core Index (the “Zacks Mid-Cap Core Index” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Mid-Cap Core ETF
Management fees		0.50%
Distribution and service (12b-1) fees	[1]	none
Other expenses		0.51%
Total annual Fund operating expenses		1.01%
Expense reimbursements	[2]	0.36%
Total annual Fund operating expenses after expense reimbursements		0.65%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Guggenheim Mid-Cap Core ETF	66	262	558	1,399

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 63% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Zacks Mid-Cap Core Index (Index Ticker: ZAXMC). As of November 30, 2012, the Index was comprised of 100 securities selected, based on investment and other criteria, from a universe of mid-capitalization securities including master limited partnerships (“MLPs”), American depositary receipts (“ADRs”) and business development companies (“BDCs”). The depositary receipts included in the Index may be sponsored or unsponsored. Currently, the mid-capitalization universe ranges from approximately $1 billion in market capitalization to $14 billion in market capitalization as defined by Zacks Investment Research, Inc. (“Zacks” or the “Index Provider”).The securities in the universe are selected using a proprietary strategy developed by Zacks. The Fund will invest at least 90% of its total assets in securities that comprise the Index and depositary receipts representing securities that comprise the Index (or underlying securities representing ADRs that comprise the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security’s corresponding depositary receipt is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although generally limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, to the extent the Fund invests in foreign securities other than ADRs, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange. Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs in the Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Medium-Sized Company Risk. Investing in securities of medium-sized companies involves greater risk than is customarily associated with investing in more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

MLP Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments.

Risks of Investing In Other Investment Companies. Investments in securities of other investment companies involve risks, including, among others, the fact that shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of premiums above the value of such companies’ portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks.

Risk of Investing in BDCs. There are certain risks inherent in investing in BDCs, whose principal business is to invest in and lend capital to privately held companies. The Investment Company Act of 1940, as amended (the “1940 Act”), imposes certain restraints upon the operations of a BDC. For example, BDCs are required to invest at least 70% of their total assets primarily in securities of private companies or thinly traded U.S. public companies, cash, cash equivalents, U.S. government securities and high quality debt investments that mature in one year or less. Generally, little public information exists for private and thinly traded companies, and there is a risk that investors may not be able to make a fully informed investment decision. With investments in debt instruments, there is a risk that the issuer may default on its payments or declare bankruptcy. Additionally, a BDC may incur indebtedness only in amounts such that the BDC’s asset coverage equals at least 200% after such incurrence. These limitations on asset mix and leverage may prohibit the way that the BDC raises capital. BDCs generally invest in less mature private companies, which involve greater risk than well-established, publicly-traded companies.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly. In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Fund Performance

The chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one year and since inception compare with those of the Index and broad measures of market performance. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information for the Fund is available at www.guggenheimfunds.com.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees of Claymore Exchange-Traded Fund Trust (the "Trust") has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.60% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees of the Trust (the "Board of Trustees"). For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Wilshire 5000 Total Market ETF

Wilshire 5000 Total Market ETF (WFVK)

Investment Objective

The Fund seeks investment results that correspond generally to the performance, before the Fund’s fees and expenses, of an equity index called the Wilshire 5000 Total Market Index^SM (the “Wilshire 5000” or the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). Investors purchasing Shares in the secondary market may be subject to costs (including customary brokerage commissions) charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Wilshire 5000 Total Market ETF
Management fees		0.12%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Total annual Fund operating expenses		0.12%

Example

This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other funds. The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	One Year	Three Years	Five Years	Ten Years
Wilshire 5000 Total Market ETF	12	94	182	443

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Wilshire 5000 (Index Ticker: W5000FLT). The Wilshire 5000 is a rules-based index comprised of, as of November 30, 2012, approximately 3,707 securities, including common stocks and real estate investment trusts (“REITs”). The Index may include securities of companies of all categories of market capitalizations (subject to the minimum requirements set forth below), as defined by Wilshire Associates Incorporated (“Wilshire®” or the “Index Provider”). The Wilshire 5000 is designed to represent the total U.S. equity market and includes all U.S. equity securities that have readily available prices. The Fund will invest at least 80% of its total assets in equity securities that comprise the Wilshire 5000. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Wilshire 5000. The Board of Trustees of the Trust (the "Board of Trustees") may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser and the Investment Sub-Adviser seek a correlation over time of 0.95 or better between the Fund’s performance and the performance of the Index. A figure of 1.00 would represent perfect correlation.

The Fund uses a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser and Investment Sub-Adviser use quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These include market capitalization, economic sector, volatility and financial characteristics of the companies. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser or Investment Sub-Adviser may choose to overweight another security in the Index or purchase (or sell) securities not in the Index which the Investment Adviser or Investment Sub-Adviser believes are appropriate to substitute for one or more Index components in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. The Fund’s Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund’s portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Consumer Staples Sector Risk. Companies in this sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drink may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources, or to depend on a small, inexperienced management group. These companies’ securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company.

REIT Risk. Investments in securities of real estate companies involve risks. These risks include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company.

Non-Correlation Risk. The Fund’s return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund’s securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Because the Fund utilizes a sampling approach (or if it otherwise holds investments other than those that comprise the Index), its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Concentration Risk. If the Index concentrates in an industry or group of industries the Fund’s investments will be concentrated accordingly, In such event, the value of the Fund’s Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index, or otherwise take defensive positions in declining markets.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund.
