Domestic Equal Weight ETF | Guggenheim S&P 100® Equal Weight ETF

GUGGENHEIM MULTI-FACTOR LARGE CAP ETF (GMFL)                             

INVESTMENT OBJECTIVE

The investment objective of the Guggenheim Multi-Factor Large Cap ETF (the “Fund”) is to replicate as closely as possible, before fees and expenses, the daily performance of the Guggenheim Multi-Factor Large Cap Index Total Return (the “Underlying Index”).

FEES AND EXPENSES OF THE FUND

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.

EXAMPLE

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:

Expense Example	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years

PORTFOLIO TURNOVER

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when 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. As of the date of this Prospectus, the Fund is new and, therefore, does not have a historical portfolio turnover rate.

PRINCIPAL INVESTMENT STRATEGIES

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, which was developed by Guggenheim Index Services^SM (the “Index Provider”), an affiliate of the Advisor, is composed of approximately 50 equity securities selected from the universe of equity securities that comprise the S&P 500^® Index. The Underlying Index component securities are selected using a Multi-Factor Composite Score, a rules-based methodology, to seek to identify those securities that will enhance returns, reduce risk and improve diversification. The Multi-Factor Composite Score seeks to identify component securities with attractive exposures to several factors or investment characteristics. Generally, these factors include both fundamental factors (i.e., value, growth and quality) and non-fundamental factors (i.e., momentum, short interest, volatility and liquidity). The Multi-Factor Composite Score uses multiple diversifying factors to seek to provide more consistent performance as compared to individual factor strategies that inherently experience cycles of underperformance when a particular factor is out of favor. The selected securities will be rebalanced quarterly to have the same target weighting as every other security in the Underlying Index. The equal weighting provides broader exposure to the majority of securities in the Underlying Index than typically may be found in a market capitalization weighted index. The Underlying Index also seeks to have a similar sector exposure as the S&P 500^® Index. As of May 31, 2017, the Underlying Index included companies with a capitalization range of $3.2 billion to $238 billion.

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 utilized by the Underlying Index.

As long as the Fund invests at least 80% of its assets, exclusive of securities lending collateral, in securities included in the Underlying Index, the Fund may invest up to 20% of its assets in certain index futures, options, options on index futures, swap contracts or other derivatives related to the Underlying Index and its component securities, as well as in securities and other instruments not included in the Underlying Index, cash and cash equivalents, and shares of other investment companies, including money market funds, that the Advisor believes will help the Fund to achieve its investment objective. 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 has significant exposure to a particular sector or is concentrated in a particular industry, the Fund will necessarily have significant exposure to that sector or 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, Health Care 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 net assets in a particular issuer in comparison to a diversified fund.

PRINCIPAL RISKS

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.

Investment Strategy Risk—There can be no assurance that the multi-factor securities selection process of the Underlying Index will identify companies that will enhance performance. Exposure to the selected factors may detract from performance in some market environments, and securities exhibiting the factors selected may underperform others that exhibit different factors.

Large-Capitalization Securities Risk—The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and may not be able to attain the high growth rate of smaller companies, especially during extended periods of economic expansion.

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.

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.

Sector Risk—The Fund is subject to the following Sector Risks:

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.

Health Care Sector Risk.The Fund's investments are exposed to issuers conducting business in the Health Care Sector. The Health Care Sector includes health care providers and services, companies that manufacture and distribute health care equipment and supplies, and health care technology companies. It also includes companies involved in the research, development, production and marketing of pharmaceuticals and biotechnology products. 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 Health Care Sector. The prices of the securities of companies operating in the Health Care Sector are closely tied to government regulation and approval of their products and services, which can have a significant effect on the price and availability of those products and services.

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.

Underlying Index Risk—Neither the Advisor nor the Index Provider is able to guarantee the continuous availability or timeliness of the production of the Underlying Index. The calculation and dissemination of the Underlying Index values may be delayed if the information technology or other facilities of the Underlying Index provider, calculation agent, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Underlying Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Underlying Index provider, calculation agent or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

PERFORMANCE INFORMATION

A comparison of the Fund’s performance with that of a broad measure of market performance may give some indication of the risks of an investment in the Fund; however, the Fund is new and, therefore, does not have a performance history for a full calendar year. Of course, once the Fund has performance, that past performance (before and after taxes) will not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at guggenheiminvestments.com or by calling 800.820.0888.

[1] Other Expenses are estimated to be less than 0.01% for the fiscal year ending October 31, 2017.
