The Guggenheim BRIC ETF (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 DR Index (the “BRIC Index” or the “Index”).

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 24% of the average value of its portfolio.

Strategy Narrative [Text Block]

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the BRIC Index. The BRIC Index is a rules-based index (i.e., an index constructed using specified criteria) comprised of American depositary receipts (“ADRs”), global depositary receipts (“GDRs”) and China H-shares of Chinese equities where appropriate, based on liquidity, from a universe of all listed depositary receipts of companies from Brazil, Russia, India and China currently trading on U.S. and non-U.S. exchanges. China H-shares are issued by companies incorporated in mainland China and listed on the Hong Kong Stock Exchange.

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 80% of its total assets in securities that comprise the Index and in the underlying securities representing ADRs and GDRs that are constituents of the Index. As of November 30, 2015, the Index consisted of 120 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 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 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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the telecommunications, energy and financial services sectors each represented a substantial portion of the Index.

Prior to October 31, 2013, the Fund sought to replicate, before the Fund’s fees and expenses, the performance of the BNY Mellon BRIC Select ADR Index (the “Prior BRIC 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.

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. If the prices of the equity securities held by the Fund fall, the value of your investment in the Fund will be adversely affected. The value of the equity and equity-related securities held by the Fund may fall (sometimes rapidly or unpredictably) 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 generally represents the riskiest investment in an issuer and 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 may generate higher average returns than other investments, common stocks generally experience more volatility in those returns. These risks are generally magnified in the case of investments in equity securities of issuers offered through initial public offerings.

Foreign Investment Risk. The Fund’s investments in or exposure to non-U.S. issuers, although generally limited to ADRs and GDRs, may involve unique or additional risks compared to investing in securities of U.S. issuers, including less market liquidity and generally greater market volatility. Brokerage commissions and other fees are generally higher for foreign investments than for domestic investments and the Fund may have limited or no legal recourse with respect to foreign securities. The Fund may at times find it difficult to value its foreign investments. 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. It may be difficult to obtain reliable information about the securities and business operations of certain foreign issuers as a result of less extensive accounting, financial and other reporting requirements in non-U.S. markets. 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.

Investments in or exposure to securities in emerging markets are generally subject to a greater level of the risks associated with investing in foreign securities, as emerging markets are considered less developed than developing countries. The less developed a country’s securities market is, the greater the level of risks. 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 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. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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.

As a result of recent events involving Ukraine and the Russian Federation, the United States and the European Union have imposed sanctions on certain Russian individuals and a Russian bank. The United States and other nations or international organizations may impose additional economic sanctions or take other actions that may adversely affect Russian-related issuers, including companies in various sectors of the Russian economy, including, but not limited to, the financial services, energy, metals and mining, engineering, and defense and defense-related materials sectors. These sanctions, any future sanctions or other actions, or even the threat of further sanctions or other actions, may negatively affect the value and liquidity of the Fund’s portfolio. For example, the Fund may be prohibited from investing in securities issued by companies subject to such sanctions, which may include securities held by the Fund in the form of ADRs and GDRs. In addition, the sanctions may require the Fund to freeze its existing investments in Russian companies, prohibiting the Fund from buying, selling or otherwise transacting in these investments. Russia may undertake countermeasures or retaliatory actions which may further impair the value and liquidity of the Fund’s portfolio and potentially disrupt its operations.

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; actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China (including both direct and indirect market stabilization efforts, which may affect valuations of Chinese issuers); and both interim and permanent market regulations may affect the ability of certain stockholders to sell Chinese securities when it would otherwise be advisable. In addition, 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.

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. Holders of certain depositary receipts may have limited voting rights and may not have the same rights typically afforded to shareholders in the event of a corporate action and may experience difficulty in receiving company stockholder communications. 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.

In addition, depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

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.

Energy Sector Risk. The energy sector is often cyclical and highly dependent on commodities prices. Securities prices for companies in the energy sector are affected by a variety of factors related to worldwide energy prices, exploration costs, energy conservation efforts and production spending. The performance of these companies and the prices of these securities are subject to changes in currency exchange rates, government regulation, world events and weather, depletion of natural resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Securities of energy companies may be subject to swift price and supply fluctuations as a result of these events, which may adversely affect the Fund. Oil and gas exploration and production can be significantly affected by natural disasters. Companies in the energy sector may be at an increased risk of civil liability and environmental damage claims, and are also subject to the risk of loss from terrorism.

Financial Services Sector Risk. The financial services sector is 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 increased competition. Companies in the financial services sector may be subject to extensive government regulation that affects the scope of their activities, the prices they can charge and the amount of capital they must maintain. The profitability and viability of companies in the financial services sector may be adversely affected by increases in interest rates, by loan losses, which usually increase in economic downturns, and by credit rating downgrades. In addition, the financial services sector is undergoing numerous changes, including continuing consolidations, development of new products and structures and changes to its regulatory framework. Furthermore, some companies in the financial services sector perceived as benefiting from government intervention in the past may be subject to future government-imposed restrictions on their businesses or face increased government involvement in their operations. Increased government involvement in the financial services sector, including measures such as taking ownership positions in financial institutions, could result in a dilution of the Fund’s investments in financial institutions. Adverse developments in the credit markets may cause companies operating in the financial services sector to incur large losses, experience declines in the value of their assets and even cease operations.

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. 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. Since the Index constituents may vary on a quarterly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Due to legal and regulatory rules and limitations, the Fund may not be able to invest in all securities included in the Index. For tax efficiency purposes, the Fund may sell certain securities to realize losses, causing it to deviate from 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 of the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

In the event economic sanctions are imposed by the United States against Russian companies included in the Index, the Fund may not be able to fully replicate the Index by investing in the relevant securities, which may lead to increased tracking error. The Fund may also need to rely on borrowings to meet redemptions, which may lead to increased expenses.

Market Price Risk. Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the net asset value (“NAV”) and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market. Given the fact that Shares can be created and redeemed in Creation Units, the Investment Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. However, the Fund may have a limited number of financial institutions that may act as “Authorized Participants.” Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund (as described under “How to Buy and Sell Shares”). If some or all of these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to create and redeem in either of these cases, Shares may trade at a discount to NAV like closed-end fund shares (and may even face delisting). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade at prices closely correlated to the Fund's next calculated NAV, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, among other factors, may result in market prices that differ significantly from NAV. Although market makers will generally take advantage of differences between the NAV and the market price of Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the NAV and/or market prices for Shares. The bid-ask spread is generally larger during periods of lower than regular trading volume in Shares or reduced market liquidity and can increase significantly during periods of market disruption or steep declines, which may be the time an investor most wants to sell its Shares. The Fund's bid-ask spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities. The Fund’s investment results are measured based upon the daily NAV of the Shares. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund.

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 or defaulted, or whose credit rating was downgraded, unless that security is removed from the Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

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, the Fund's performance may depend on the performance of a small number of issuers and the Fund may be more susceptible to risks associated with and adverse developments affecting a single issuer, including changes in the market value of the issuer's securities and unfavorable market and economic developments. These events could cause a greater impact on the Fund and fluctuations in Share price than would occur in a diversified fund.

Tax Risks. In order to qualify for the favorable tax treatment generally available to regulated investment companies (“RICs”) and avoid Fund-level taxes, the Fund must satisfy certain income and asset composition requirements, as well as certain distribution requirements. If the Fund fails to satisfy the distribution requirement necessary to qualify for treatment as a RIC for any taxable year, the Fund would be treated as a corporation subject to U.S. federal income tax, thereby subjecting any income earned by the Fund to tax at the corporate level. If the Fund fails to satisfy a separate distribution requirement, it will be subject to a Fund-level excise tax.

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 Defensive Equity Index. As of November 30, 2015, 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 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 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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the financial services and utilities sectors each represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Foreign Investment Risk. The Fund’s investments in or exposure to non-U.S. issuers, although generally limited to ADRs, may involve unique or additional risks compared to investing in securities of U.S. issuers, including less market liquidity and generally greater market volatility. Brokerage commissions and other fees are generally higher for foreign investments than for domestic investments and the Fund may have limited or no legal recourse with respect to foreign securities. The Fund may at times find it difficult to value its foreign investments. 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. It may be difficult to obtain reliable information about the securities and business operations of certain foreign issuers as a result of less extensive accounting, financial and other reporting requirements in non-U.S. markets. 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. Holders of certain depositary receipts may have limited voting rights and may not have the same rights typically afforded to shareholders in the event of a corporate action and may experience difficulty in receiving company stockholder communications. 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.

In addition, depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

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.

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. 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. 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. MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region. Furthermore, as partnerships, MLPs may be subject to less regulation (and less protection for investors) under state laws than corporations. Securities issued by MLPs may experience limited trading volumes and, thus, may be relatively illiquid or volatile at times. There are also certain tax risks associated with an investment in units of MLPs. A change in current tax law or a change in the underlying business of a given MLP could adversely affect the Fund's investment in an MLP.

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Insider Sentiment Index. As of November 30, 2015, 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 all 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 may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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.

The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the financial services, consumer discretionary and consumer staples sectors each represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

In addition, depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

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.

Consumer Staples Sector Risk. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumer staples sector are also affected by changes in government regulation, global economic, environmental and political events, economic conditions and the depletion of resources. In addition, companies in the consumer staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions.

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. 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.

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 or defaulted, or whose credit rating was downgraded, unless that security is removed from the Insider Sentiment Index. In addition, the Fund will not otherwise take defensive positions in declining markets unless such positions are reflected in the Index.

Portfolio Turnover Risk. The Fund may engage in active and frequent trading of its portfolio securities to reflect the quarterly rebalancing of the Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of the year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs and may result in higher taxes when Shares are held in a taxable account.

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 Zacks Mid-Cap Core Index. As of November 30, 2015, 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 $2 billion in market capitalization to $16 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 may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the financial services and industrials sectors each represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

In addition, depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

Industrials Sector Risk. The prices of securities of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general, which may be cyclical. 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 industrials sector. Companies in the industrials sector may be at risk for environmental damage and product liability claims and may be adversely affected by changes or trends in commodity prices, imposition of import controls, labor relations and insurance costs.

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. 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.

Risks of Investing in Other Investment Companies. Investing in other investment companies, including exchange-traded funds ("ETFs") and closed-end funds, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying investment companies' expenses and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of substantial premiums above the value of such companies’ portfolio securities or net asset values ("NAVs"). 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. Since the Index constituents may vary on a quarterly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other ETFs that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Market Price Risk. Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market. Given the fact that Shares can be created and redeemed in Creation Units, the Investment Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. However, the Fund may have a limited number of financial institutions that may act as “Authorized Participants.” Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund (as described under “How to Buy and Sell Shares”). If some or all of these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to create and redeem in either of these cases, Shares may trade at a discount to NAV like closed-end fund shares (and may even face delisting). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade at prices closely correlated to the Fund's next calculated NAV, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, among other factors, may result in market prices that differ significantly from NAV. Although market makers will generally take advantage of differences between the NAV and the market price of Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the NAV and/or market prices for Shares. The bid-ask spread is generally larger during periods of lower than regular trading volume in Shares or reduced market liquidity and can increase significantly during periods of market disruption or steep declines, which may be the time an investor most wants to sell its Shares. The Fund's bid-ask spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities. The Fund’s investment results are measured based upon the daily NAV of the Shares. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund.

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Zacks Multi-Asset Income Index. As of November 30, 2015, the Zacks Multi-Asset Income Index was comprised of approximately 148 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 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 may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the financial services and energy sectors each represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

In addition, depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

REIT Risk. REITs are exposed to the risks affecting real estate investments generally in addition to other investment risks. The risks of investing in real estate companies 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; the impact of changes in environmental laws; and intense competition and periodic overbuilding. The value of a REIT can depend on the structure of and cash flow generated by the REIT. REITs whose investments are concentrated in a limited number or type or properties, investments or narrow geography area are subject to the risks affecting those properties or areas to a greater extent than a REIT with less concentrated investments. A REIT may be more volatile and/or more illiquid than other types of equity securities. In addition, like investment companies, 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 the event of a default of an underlying borrower or lessee, a REIT could experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments.

In addition, REITs are subject to certain provisions under federal tax law, including a requirement that REITs distribute substantially all of their net income to their shareholders, which may result in a REIT having insufficient capital for future expenditures. 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.

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.

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. Since the Index constituents may vary on a quarterly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other ETFs that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

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 which comprise the Index, its return may not correlate as well with the return of the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

Market Price Risk. Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market. Given the fact that Shares can be created and redeemed in Creation Units, the Investment Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. However, the Fund may have a limited number of financial institutions that may act as “Authorized Participants.” Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund (as described under “How to Buy and Sell Shares”). If some or all of these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to create and redeem in either of these cases, Shares may trade at a discount to NAV like closed-end fund shares (and may even face delisting). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade at prices closely correlated to the Fund's next calculated NAV, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, among other factors, may result in market prices that differ significantly from NAV. Although market makers will generally take advantage of differences between the NAV and the market price of Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the NAV and/or market prices for Shares. The bid-ask spread is generally larger during periods of lower than regular trading volume in Shares or reduced market liquidity and can increase significantly during periods of market disruption or steep declines, which may be the time an investor most wants to sell its Shares. The Fund's bid-ask spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities. The Fund’s investment results are measured based upon the daily NAV of the Shares. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund.

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. 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”), master limited partnerships (“MLPs”) and business development companies ("BDCs"). 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, 2015, the market capitalization range of Index constituents was $63 million to $500 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 (the "Board") of Claymore Exchange-Traded Fund Trust (the “Trust”) may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the consumer discretionary and financial services sectors each represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

In addition, depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

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. 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.

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 Securities and Exchange Commission (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.

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. 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 ETFs that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

Market Price Risk. Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market. Given the fact that Shares can be created and redeemed in Creation Units, the Investment Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. However, the Fund may have a limited number of financial institutions that may act as “Authorized Participants.” Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund (as described under “How to Buy and Sell Shares”). If some or all of these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to create and redeem in either of these cases, Shares may trade at a discount to NAV like closed-end fund shares (and may even face delisting). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade at prices closely correlated to the Fund's next calculated NAV, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, among other factors, may result in market prices that differ significantly from NAV. Although market makers will generally take advantage of differences between the NAV and the market price of Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the NAV and/or market prices for Shares. The bid-ask spread is generally larger during periods of lower than regular trading volume in Shares or reduced market liquidity and can increase significantly during periods of market disruption or steep declines, which may be the time an investor most wants to sell its Shares. The Fund's bid-ask spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities. The Fund’s investment results are measured based upon the daily NAV of the Shares. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund.

Portfolio Turnover Risk. The Fund may engage in active and frequent trading of its portfolio securities to reflect the semi-monthly rebalancing of the Index. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of the year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs and may result in higher taxes when Shares are held in a taxable account.

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 Spin-Off Index. As of November 30, 2015, the Spin-Off Index was comprised of approximately 40 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 may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the financial services, consumer staples and telecommunications sectors each represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

In addition, depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

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. 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.

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 on a semi-annual basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds ("ETFs") that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

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 of the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

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.

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 30% of the average value of its portfolio.

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund, using a “passive” or “indexing” investment approach, will seek to replicate, before the Fund’s fees and expenses, the performance of the Wilshire Micro-Cap. The Wilshire Micro-Cap is a rules-based index (i.e., an index based on specified criteria) comprised of, as of November 30, 2015, approximately 1,192 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 Index^SM (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 (the "Board") of Claymore Exchange-Traded Fund Trust (the “Trust”) may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the financial services and consumer staples sectors each represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

REIT Risk. REITs are exposed to the risks affecting real estate investments generally in addition to other investment 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; the impact of changes in environmental laws; and intense competition and periodic overbuilding. The value of a REIT can depend on the structure of and cash flow generated by the REIT. REITs whose investments are concentrated in a limited number or type or properties, investments or narrow geography area are subject to the risks affecting those properties or areas to a greater extent than a REIT with less concentrated investments. A REIT may be more volatile and/or more illiquid than other types of equity securities. In addition, like investment companies, 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 the event of a default of an underlying borrower or lessee, a REIT could experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments.

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. These companies’ securities may be more volatile and less liquid than those of more established companies. Securities of small companies tend to have inexperienced management as well as limited product and market diversification and financial resources and may be more vulnerable to adverse economic, market or industry developments than larger, 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. Since the Index constituents may vary on a monthly basis, the Fund’s costs associated with rebalancing may be greater than those incurred by other ETFs that track indices whose composition changes less frequently. In addition, the performance of the Fund and the Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Index resulting from legal restrictions, cash flows or operational inefficiencies.

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 which comprise the Index, its return may not correlate as well with the return of the Index as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.

Market Price Risk. Shares are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market at market prices. The market prices of Shares may fluctuate continuously during trading hours, in some cases materially, in response to changes in the NAV and supply and demand for Shares, among other factors. Although it is expected that the market price of Shares typically will remain closely correlated to the NAV, the market price will generally differ from the NAV because of timing reasons, supply and demand imbalances and other factors. As a result, the trading prices of Shares may deviate significantly from NAV during certain periods, especially those of market volatility. The Investment Adviser cannot predict whether Shares will trade above (premium), below (discount) or at their NAV. Thus, an investor may pay more than NAV when buying Shares in the secondary market and receive less than NAV when selling Shares in the secondary market. Given the fact that Shares can be created and redeemed in Creation Units, the Investment Adviser believes that large discounts or premiums to the NAV of Shares should not be sustained in the long-term. However, the Fund may have a limited number of financial institutions that may act as “Authorized Participants.” Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund (as described under “How to Buy and Sell Shares”). If some or all of these Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to create and redeem in either of these cases, Shares may trade at a discount to NAV like closed-end fund shares (and may even face delisting). Further, while the creation/redemption feature is designed to make it likely that Shares normally will trade at prices closely correlated to the Fund's next calculated NAV, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants or market participants, or during periods of significant market volatility, among other factors, may result in market prices that differ significantly from NAV. Although market makers will generally take advantage of differences between the NAV and the market price of Shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the NAV and/or market prices for Shares. The bid-ask spread is generally larger during periods of lower than regular trading volume in Shares or reduced market liquidity and can increase significantly during periods of market disruption or steep declines, which may be the time an investor most wants to sell its Shares. The Fund's bid-ask spread may also be impacted by the liquidity of the underlying securities held by the Fund, particularly for newly launched or smaller funds or in instances of significant volatility of the underlying securities. The Fund’s investment results are measured based upon the daily NAV of the Shares. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund.

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 11% of the average value of its portfolio.

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 Wilshire US REIT. The Wilshire US REIT is a rules-based index comprised of, as of November 30, 2015, approximately 114 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 Index^SM. 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 (the "Board") of Claymore Exchange-Traded Fund Trust (the “ Trust”) may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

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, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets (to the extent the Fund invests in underlying securities representing ADRs included in the Index) which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, 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 pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of August 31, 2015, the financial services sector represented a substantial portion of the Index.

Risk [Heading]

rr_RiskHeading

Principal Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

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. Interest rates in the United States are at, or near, historic lows, which may increase the Fund's exposure to risks associated with rising rates because interest rates are expected to start increasing in the foreseeable future, with unpredictable impacts on the markets and the Fund's investments. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy (including the Federal Reserve's continued tapering or reversal of its "quantitative easing" policy of purchasing large quantities of securities issued or guaranteed by the U.S. government), rising inflation and changes in general economic conditions. Interest rate changes can be sudden and unpredictable.

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 during 2007 through 2009.

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 during 2007 through 2009.

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. 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.

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 of the Index, as would be the case if it purchased all of the stocks in the Index with the same weightings as the Index.
