Summary Prospectus

Before you invest, you may wish to review the Fund’s Prospectus, which contains more information about the Fund and its risks. You may obtain the Prospectus and other information about the Fund, including the Statement of Additional Information (SAI) and most recent reports to shareholders, at no cost by visiting guggenheiminvestments.com/services/prospectuses-and-reports, calling 800.820.0888 or e-mailing services@guggenheiminvestments.com. The Fund’s Prospectus and SAI, both dated February 28, 2017, as revised from time to time, and the Fund’s most recent shareholder reports, are incorporated by reference into this Summary Prospectus.

The investment objective of the Guggenheim S&P MidCap 400^® Equal Weight ETF (the “Fund”) is to correspond as closely as possible, before fees and expenses, to the price and yield performance of the S&P MidCap 400^® Equal Weight Index (the “Underlying Index”).

The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Most investors also will incur customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the table or the Example. If commissions were included in the table and the Example, the costs shown would be higher.



Shareholder Fees (fees paid directly from your investment)	None
Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.40	%
Distribution (12b-1) Fees	0.00	%
Other Expenses	0.01	%
Total Annual Fund Operating Expenses	0.41	%

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

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 Fund shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 101% of the average value of its portfolio. However, the Fund’s portfolio turnover rate is calculated without regard to cash instruments, most derivatives and securities received or delivered as a result of in-kind creations and redemptions of the Fund’s shares. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund invests primarily in equity securities to meet its investment objective of replicating the Underlying Index as closely as possible, before fees and expenses. The Underlying Index is an unmanaged equal weighted version of the S&P MidCap 400^® Index, which measures the performance of the mid-cap segment of the U.S. equity universe. The S&P MidCap 400^® Index consists of U.S. common equities listed on the New York Stock Exchanges (including NYSE Arca and NYSE Amex) and NASDAQ, and also may include equity interests in real estate investment trusts and business development companies. As of December 31, 2016, the Underlying Index included medium-capitalization companies with capitalizations ranging from $1.2 billion to $10.5 billion. In general, the equal weighting provided by the Underlying Index provides equal representation for all securities at the Underlying Index’s rebalance interval(s), thereby providing broader exposure to the majority of securities in the Underlying Index than typically may be found in the Underlying Index’s market capitalization weighted counterpart.

The Fund uses a passive management strategy, known as “replication,” to track the performance of the Underlying Index. “Replication” refers to investing in substantially all of the securities in the Underlying Index in approximately the same proportions as in the Underlying Index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in the equity securities included in the Underlying Index. The Advisor expects that, over time, the correlation between the Fund’s performance, before fees and expenses, and that of the Underlying Index will be 95% or better. A figure of 100% would indicate perfect correlation. The Advisor monitors the Fund’s tracking of the Underlying Index and seeks to maintain an appropriate correlation. The Advisor rebalances the Fund’s portfolio at the same rebalance interval(s) utilized by the Underlying Index.

As long as the Fund invests at least 80% of its total assets in securities included in the Underlying Index, the Fund may hold up to 20% of its assets in securities not included in the Underlying Index, futures contracts, options on futures contracts, options, and swaps related to the Underlying Index, as well as cash and cash equivalents, and shares of investment funds, including money market funds. On a day-to-day basis, the Fund may also hold repurchase agreements, U.S. Government securities or cash equivalents to collateralize its derivatives positions. In an effort to make sure the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets.

To the extent the Underlying Index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. As of the date of this Prospectus, the Fund anticipates that it may have significant exposure to the Consumer Discretionary Sector, Financials Sector, Industrials Sector, and Information Technology Sector, as each sector is defined by the Global Industry Classification Standard, a widely recognized industry classification methodology developed by MSCI, Inc. and Standard & Poor's Financial Services LLC. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

As with all exchange-traded funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value or liquidity of its shares, including:

Authorized Participant Concentration Risk—Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that serve as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund shares may trade at a discount to net asset value ("NAV") and possibly face delisting.

Correlation and Tracking Error Risk—A number of factors may affect the Fund’s ability to achieve a high degree of correlation with its Underlying Index, and there can be no guarantee that the Fund will achieve a high degree of correlation with its Underlying Index either on a single trading day or for a longer time period. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and the components of the Underlying Index, rounding of share prices, changes to the composition of the Underlying Index, regulatory policies, a high portfolio turnover rate, and the use of leverage all contribute to tracking error and correlation risk. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective and cause the Fund's performance to be less than you expect.

Equity Risk—The Fund is subject to the risk that the value of the equity securities and equity-based derivatives, if any, in the Fund’s portfolio will decline due to volatility in the equity market caused by general market and economic conditions, perceptions regarding particular industries represented in the equity market, or factors relating to specific companies to which the Fund has investment exposure.

ETF Trading Risks—An unanticipated closing of the Exchange or one or more markets on which either the Fund’s shares trade or the Fund’s portfolio holdings trade or the inability of such markets to open for trading during normal business hours, such as in response to a natural disaster or other event causing severe market disruption, could result in a shareholder’s inability to buy or sell shares of the Fund and the Fund’s inability to buy and sell exchange-traded portfolio securities during that period, or in a disruption of the Fund’s creation and redemption process, and may make it difficult for the Fund to accurately price its investments thereby potentially affecting the price at which Fund shares trade in the secondary market. All of these events could adversely affect the performance of the Fund. Trading in Fund shares also may be halted by the Exchange or other markets because of market conditions or other reasons.

If a trading halt occurs, a shareholder may temporarily be unable to purchase or sell shares of the Fund. Similarly, the Exchange or other markets may issue trading halts on specific securities or derivatives, which will affect the ability of the Fund to buy or sell certain securities or derivatives. In such circumstances, the Fund may be unable to rebalance its portfolio or accurately price its investments and may incur substantial trading losses.

Shares also may trade on the Exchange or on other markets at prices below their NAV. The NAV of shares will fluctuate with changes in the market value of the Fund’s holdings and the exchange-traded prices of the Fund's shares may not reflect these market values. Although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained.

Liquidity and Valuation Risk—In certain circumstances, it may be difficult for the Fund to purchase and sell a particular investment within a reasonable time at a fair price, or the price at which it has been valued by the Advisor for purposes of the Fund’s NAV, causing the Fund to be less liquid. While the Fund intends to invest in liquid securities and financial instruments, under certain market conditions, such as when trading in a particular investment has been halted temporarily by an exchange because the maximum price change of that investment has been realized, it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.

Market Risk—The market value of the securities and derivatives (if any) held by the Fund may fluctuate over time in response to factors affecting individual companies or other factors such as changing economic, political or financial market conditions.

Mid-Capitalization Securities Risk—The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Securities of medium-capitalization companies may experience more price volatility, greater spreads between their bid and ask prices, lower trading volumes, and cyclical or static growth prospects. Medium-capitalization companies often have limited product lines, markets or financial resources, and may therefore be more vulnerable to adverse developments than larger capitalization companies.

Non-Diversification Risk—The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single issuer's securities could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.

Passive Investment Risk—The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.

Consumer Discretionary Sector Risk. The Fund’s investments are exposed to issuers conducting business in the Consumer Discretionary Sector. The manufacturing segment of the Consumer Discretionary Sector includes automotive, household durable goods, leisure equipment and textiles and apparel. The services segment includes hotels, restaurants and other leisure facilities, media production and services, and consumer retailing and services. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Consumer Discretionary Sector. The performance of companies operating in the Consumer Discretionary Sector has historically been closely tied to the performance of the overall economy, and is also affected by economic growth, consumer confidence, attitudes and spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace. Moreover, the Consumer Discretionary Sector encompasses those businesses that tend to be the most sensitive to economic cycles.

Financials Sector Risk. The Fund's investments are exposed to issuers conducting business in the Financials Sector. The Financials Sector includes companies involved in banking, thrifts and mortgage finance, specialized finance, consumer finance, asset management and custody banks, investment banking and brokerage and insurance. It also includes Financial Exchanges and Data and Mortgage REITs. The Fund is

subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Financials Sector. Companies operating in the Financials Sector are subject to extensive government regulation, which may limit the financial commitments they can make and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition.

Industrials Sector Risk. The Fund's investments are exposed to issuers conducting business in the Industrials Sector. The Industrials Sector includes manufacturers and distributors of capital goods such as aerospace and defense, building projects, electrical equipment and machinery and companies that offer construction and engineering services. It also includes providers of commercial and professional services including printing, environmental and facilities services, office services and supplies, security and alarm services, human resource and employment services, research and consulting services. It also includes companies that provide transportation services. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Industrials Sector. The prices of the securities of companies operating in the Industrials Sector may fluctuate due to the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Information Technology Sector Risk. The Fund's investments are exposed to issuers conducting business in the Information Technology Sector. The Information Technology Sector includes companies that offer software and information technology services, manufacturers and distributors of technology hardware and equipment such as communications equipment, cellular phones, computers and peripherals, electronic equipment and related instruments and semiconductors. The Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Information Technology Sector. The prices of the securities of companies operating in the Information Technology Sector are closely tied to market competition, increased sensitivity to short product cycles and aggressive pricing, and problems with bringing products to market.

The following bar chart shows the performance of the shares of the Fund from year to year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the performance of the shares of the Fund as an average over different periods of time in comparison to the performance of the Underlying Index and the S&P MidCap 400^® Index, which is the market capitalization weighted version of the Underlying Index. Effective January 26, 2016, the Fund adopted its current investment objective. Prior to January 26, 2016, the Fund sought to correspond as closely as possible, before fees and expenses, to the price and yield performance of the Russell MidCap^® Equal Weight Index Total Return. The performance and average annual total returns shown for periods prior to January 26, 2016 would have differed had the Fund's current investment objective been in effect during those periods. The figures in the bar chart and table assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”).



	Past 1 Year	Past 5 Years	Since Inception (12/3/2010)
Return Before Taxes	22.46%	14.94%	12.68%
Return After Taxes on Distributions	21.87%	14.25%	12.05%
Return After Taxes on Distributions and Sale of Fund Shares	12.68%	11.66%	9.92%
S&P MidCap 400^® Equal Weight Index (reflects no deduction for fees, expenses or taxes)	23.95%	15.21%	12.49%
S&P MidCap 400^® Index (reflects no deduction for fees, expenses or taxes)	20.74%	15.33%	12.58%

Shares may be purchased and redeemed from the Fund only in “Creation Units” of 50,000 shares, or multiples thereof. As a practical matter, only institutions and large investors, such as market makers or other large broker-dealers, purchase or redeem Creation Units. Most investors will buy and sell shares of the Fund on the Exchange. Individual shares can be bought and sold throughout the trading day like other publicly traded securities through a broker-dealer on the Exchange. These transactions do not involve the Fund. The price of an individual Fund share is based on market prices, which may be different from its NAV. As a result, the Fund’s shares may trade at a price greater than the NAV (at a premium) or less than the NAV (at a discount). Most investors will incur customary brokerage commissions and charges when buying or selling shares of the Fund through a broker-dealer on the Exchange.

Fund distributions are generally taxable as ordinary income, qualified dividend income or capital gains (or a combination thereof), unless your investment is in an IRA or other tax-advantaged retirement account. Investments through a tax-advantaged retirement account may be subject to taxation upon withdrawal.

If you purchase Fund shares through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your sales person to recommend the Fund over another investment. Ask your sales person or visit your financial intermediary’s website for more information.
