September 30, 2016

Slow and steady economic growth, a cautious U.S. Federal Reserve (the "Fed"), low interest rates, and improving oil market supply-demand fundamentals have created a favorable environment for markets, as of the end of August 2016. Gross domestic product (GDP) growth was soft in the second quarter (1.4 percent was the final reading, reported at the end of September), modestly up from the first quarter's 0.8 percent. But, the headline figures belie underlying strength.

Solid fundamentals in the consumer sector underpin our confidence in the near-term growth outlook, thanks to payroll and labor market gains, and household debt and debt service coverage ratios that are well below pre-crisis peaks. We expect third-quarter GDP to be significantly better than the previous two quarter prints.

Despite this relatively healthy economic backdrop, we expect the Fed to delay its next rate hike until December. September and October can be seasonally weak periods for the market in our view, and policymakers will take time to gauge the implications of Brexit, as well as watch for signs of firmer growth and inflation. Meanwhile, the European Central Bank and Bank of Japan are likely to follow the Bank of England in increasing accommodation, but skepticism abounds about the effectiveness of additional monetary easing and negative rates.

Monetary policy divergence is likely to benefit the U.S. dollar in the near term, which would pose headwinds for the recovery in crude oil prices. Our oil price model calls for a period of seasonal weakness in the second half of 2016 before prices rise to $55 by mid-2017.

As the world's major economies are mired with record low bond yields, practically non-existent inflationary pressure, and lackluster economic growth, it is increasingly difficult for policymakers to simply hope that even lower rates and more quantitative easing alone will reach the desired employment and inflation targets. The current monetary policy regime appears unable to succeed alone, and it may be time for aggressive fiscal policy to be added into the global policy mix.

The market remains awash in liquidity with global central banks at the ready to do more if necessary. The rally in risk assets is likely to continue at least through the third quarter, although not without intermittent volatility.

For the 12 months ended August 31, 2016, the Standard & Poor's 500^® ("S&P 500") Index returned 12.55%. The MSCI Europe-Australasia-Far East ("EAFE") Index returned -0.12%. The return of the MSCI Emerging Markets Index was 11.83%.

In the bond market, the Bloomberg Barclays U.S. Aggregate Bond Index posted a 5.97% return for the period, while the Bloomberg Barclays U.S. Corporate High Yield Index returned 9.07%. The return of the Bank of America Merrill Lynch 3-Month U.S. Treasury Bill Index was 0.23% for the 12-month period.

GTO Guggenheim Total Return Bond ETF

Fund Overview
The Guggenheim Total Return Bond ETF, NYSE Arca ticker: GTO (the "Fund") seeks maximum total return, comprised of income and capital appreciation.

In managing the Fund, Guggenheim Partners Investment Management ("GPIM") uses a process for selecting securities for purchase and sale that is based on intensive credit research and involves extensive due diligence on each issuer, region, and sector. GPIM also considers macroeconomic outlook and geopolitical issues.

These targets are set based on the interest rate outlook, the macro environment, and can be either absolute or relative to a portfolio's positioning to a benchmark.

The Fund will normally invest in a portfolio of fixed income instruments of varying maturities and of any credit quality. The Fund will normally invest at least 80% of its assets in fixed income instruments and also include exchange traded funds ("ETFs") and closed-end funds ("CEFs") that invest substantially all of their assets in fixed income instruments. The Fund may invest in short-term instruments such as commercial paper, repurchase agreements, reverse repurchase agreements and short-term investment funds.

The fixed-income instruments in which the Fund invests include corporate debt securities of U.S. and non-U.S. issuers, including corporate bonds and other similar instruments, such as Treasury securities, collateralized loan obligations ("CLOs"), mortgage-backed securities ("MBS"), and asset-backed securities ("ABS"), issued by various U.S. and non-U.S. public- or private-sector entities, and municipal securities.

At the end of the period the Fund's shares were trading at a slight market price premium to NAV, which is to be expected from time to time. All NAV returns include the deduction of management fees, operating expenses, and all other Fund expenses.

For comparison, the Bloomberg Barclays U.S. Aggregate Bond Index returned 3.79% for the same period.

The Fund made the following monthly distributions for the abbreviated annual fiscal period ended August 31, 2016:

Performance Review
As the Fund launched, many assets were trading at multi-year low valuations after a bout of volatility that followed the U.S. Federal Reserve's December 2015 rate hike, presenting one of the better investment opportunities in the last several years.

The Fund's positive return for the period resulted from the tightening of credit spreads, the Fund's carry, as well as its duration positioning. Positive spread returns stemmed primarily from collateralized loan obligations (CLOs), as well as from non-agency residential mortgage-backed securities (NA RMBS) and investment grade corporate bonds. The Fund continues to maintain less interest rate duration than the benchmark, particularly at the front end of the curve.

The Fund's CLO investments focused on credits from the more highly rated tranches, which by the end of the period had reached post-crisis tights. CLO issuance was weak for the period due to waning demand from foreign investors adversely affected by currency fluctuations, as well as "fast-money" investors still reeling from high volatility at the beginning of 2016. CLO creation was also reduced by limited bank loan supply. Bank loans underperformed other fixed-rate bond markets over the period, although, as anticipated, delivering steady returns with limited volatility.

Residential mortgages provided another source of Fund outperformance. Exposure to NA RMBS benefited from improving housing market conditions, strong borrower credit performance, and favorable market supply dynamics.

U.S. investment grade corporate bonds' attractive yields relative to similarly rated corporate bonds overseas attracted strong demand from foreign as well as domestic investors, supporting robust monthly volumes through most of the period. Investment-grade yields are near all-time lows, but spreads are still wide of the historical ex-recession average. Investment-grade corporate bonds performed strongly with the largest spread moves in energy and metals and mining. Higher commodity prices (particularly oil) have alleviated tail risks globally and attracted buyers of investment-grade credit in the energy and metals and mining sectors.

 

OVLC Guggenheim U.S. Large Cap Optimized Volatility ETF

Fund Overview
The Guggenheim U.S. Large Cap Optimized Volatility ETF, NYSE Arca ticker: OVLC (the "Fund") seeks investment results that correspond generally to the performance, before the Fund's fees and expenses, of the Guggenheim U.S. Large Cap Optimized Volatility Index (the "Index"). The Index, composed of approximately 120 securities, is designed to capture the benefits of low volatility investing while outperforming these strategies during market rallies. The Index's optimized volatility methodology attempts to have a low volatility exposure much of the time but adopts a higher volatility exposure as market reward-to-risk levels dictate. By utilizing a systematic process to optimize the Index methodology's volatility profile, the Index is designed to provide attractive risk-adjusted returns across a market cycle.

Index constituents must be constituents of the S&P 500 Index. Accretive Asset Management, LLC (the "Index Provider") is affiliated with Guggenheim Funds Investment Advisors, LLC (the "Investment Adviser") and Guggenheim Funds Distributors, LLC (the "Distributor"). The Index Provider selects securities from the constituents of the S&P 500 Index for inclusion in the Index using a proprietary methodology that calculates the reward to risk of each security in the investable universe.

The Fund will invest at least 80% of its total assets in securities that comprise the Index. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index.

Fund Performance
All Fund returns cited—whether based on net asset value ("NAV") or market price—assume the reinvestment of all distributions. This report discusses the abbreviated annual fiscal period beginning at the Fund's inception of May 10, 2016, through August 31, 2016.

On a market price basis, the Fund generated a total return of 3.98%, which included an increase in market price over the period to $26.14 on August 31, 2016, from $25.14 at inception. On an NAV basis, the Fund generated a total return of 4.22%, which included an increase in NAV over the period to $26.20 on August 31, 2016, from $25.14 at inception. At the end of the period the Fund's shares were trading at a market price discount to NAV, which is to be expected from time to time. All NAV returns include the deduction of management fees, operating expenses, and all other Fund expenses.

For comparison, the Index returned 4.35%, and the S&P 500 Index returned 6.24% for the abbreviated fiscal period.

Performance Attribution
For the abbreviated fiscal period ended August 31, 2016, the information technology sector contributed the most to the Fund's return, followed by the consumer staples sector. The consumer discretionary sector was the only sector to detract from the Fund's return.

Positions that contributed the most to the Fund's return included eBay, Inc., an e-commerce company that provides consumer-to-consumer and business-to-consumer sales services; Apple, Inc., a technology company that designs, develops, and sells consumer electronics, computer software, and online services; and Kinder Morgan, Inc., the largest energy infrastructure company in North America specializing in owning and controlling oil and gas pipelines and terminals (1.5%, 3.3%, and 1.4%, respectively, of the Fund's long-term investments at period end).

Positions that detracted the most from the Fund's return included Bristol-Myers Squibb Co., a pharmaceutical company (1.3% of the Fund's long-term investments at period end); McDonald's Corp., the world's largest chain of hamburger fast food restaurants (1.5% of the Fund's long-term investments at period end); and Nike, Inc., Class B, which is engaged in the design, development, manufacturing, and worldwide marketing and sales of footwear, apparel, equipment, accessories, and services (not held in the portfolio at period end).

 

This information does not represent an offer to sell securities of the Funds and it is not soliciting an offer to buy securities of the Funds. An investment in the various Guggenheim ETFs is subject to certain risks and other considerations. Below are some general risks and considerations associated with investing in a Fund, which may cause you to lose money, including the entire principal that you invest. Please refer to each individual ETF prospectus for a more detailed discussion of Fund-specific risks and considerations.

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

Equity Risk. The value of the securities held by each Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by each Fund participate, or factors relating to specific companies in which such Fund invests.

Foreign Investment Risk. A Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including, among others, greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic, or social developments could undermine the value of such Fund's investments or prevent such Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the U.S. Finally, the value of the currency of the country in which a 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. In addition, 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.

Emerging Markets Risk. Investment in securities of issuers based in developing or "emerging market" countries entails all of the risks of investing in securities of non-U.S. issuers, as previously described, but to a heightened degree.

Micro-, Small-, and Medium-Sized Company Risk. Investing in securities of these companies involves greater risk as their stocks may be more volatile and less liquid than investing in more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market. Micro-cap companies may be newly formed, less developed, and there may be less available information about the company.

Replication Management Risk. The Funds are not "actively" managed. Therefore, a Fund would not necessarily sell a security because the stock's issuer was in financial trouble unless that stock is removed from such Fund's Index.

Non-Correlation Risk. A Fund's return may not match the return of such Fund's 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. A Fund may not be fully invested at times, either as a result of cash flows into such Fund or reserves of cash held by a Fund to meet redemptions and expenses. If a Fund utilizes a sampling approach or futures or other derivative positions, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index.

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

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

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.

China Investment Risk (YAO and CQQQ). Investing in securities of Chinese companies involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources, and capital reinvestment, among others; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China.

Guggenheim Emerging Markets Real Estate ETF may not be suitable for all investors. Investments in the real estate industry, including REITS, subjects the Fund to the same risks as direct investments in real estate, which are particularly sensitive to economic downturns. Investments in foreign securities carry additional risks when compared to U.S. securities, due to the impact of diplomatic, political, or economic developments in the country in question (investments in emerging markets securities are generally subject to an even greater level of risks). Investments in Chinese companies may also involve additional risks. Investments in small- or medium-sized

companies may involve greater risk than investing in larger, more established companies. Investments in securities of smaller issuers can be more volatile than that of larger issuers. Investments in micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable and their shares tend to be more volatile and their markets less liquid than companies with larger market capitalizations.

Recent Market Developments Risk. Global and domestic financial markets have experienced periods of unprecedented turmoil. Recently, markets have witnessed more stabilized economic activity as expectations for an economic recovery increased. However, risks to a robust resumption of growth persist. Continuing uncertainty as to the status of the euro and the European Monetary Union has created significant volatility in currency and financial markets generally. A return to unfavorable economic conditions or sustained economic slowdown could adversely impact the Funds' portfolios. Financial market conditions, as well as various social and political tensions in the U.S. and around the world, have contributed to increased market volatility and may have long-term effects on the U.S. and worldwide financial markets and cause further economic uncertainties or deterioration in the U.S. and worldwide. The Investment Advisor does not know how long the financial markets will continue to be affected by these events and cannot predict the effects of these or similar events in the future on the U.S. and global economies and securities markets.

There is no assurance that the requirements of the NYSE Arca necessary to maintain the listing of the Funds will continue to be met or will remain unchanged.

In addition to the risks described, there are certain other risks related to investing in the Funds. These risks are described further in each Fund's Prospectus and Statement of Additional Information and at guggenheiminvestments.com.

All funds have operating expenses and it is important for our shareholders to understand the impact of costs on their investments. Shareholders of a Fund incur advisory fees and other Fund expenses which are deducted from a Fund's gross income and reduce the investment return of the Fund.

A fund's expenses are expressed as a percentage of its average net assets, which is known as the expense ratio. The following examples are intended to help investors understand the ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other funds.

The examples are based on an investment of $1,000 made at the beginning of the period and held for the entire six-month period beginning February 29, 2016 and ending August 31, 2016.

The following tables illustrate a Fund's costs in two ways:

The table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses paid during the period. The example is useful in making comparisons because the U.S. Securities and Exchange Commission (the "SEC") requires all mutual funds to calculate expenses based on the 5% return. Investors can assess a Fund's costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds.

The calculations illustrated above assume no shares were bought or sold during the period. Actual costs may have been higher or lower, depending on the amount of investment and the timing of any purchases or redemptions.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) on purchase payments, and contingent deferred sales charges ("CDSC") on redemptions, if any. Therefore, the second table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

More information about a Fund's expenses, including annual expense ratios for the past five years, can be found in the Financial Highlights section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate Fund prospectus.
