Summary Prospectus

Before you invest, you may want to review the Fund’s prospectus, which contains more information about the Fund and its risks. You can find the Fund’s prospectus and other information about the Fund online at guggenheiminvestments.com. You can also get this information at no cost by calling 800.820.0888 or by sending an e-mail request to etfinfo@guggenheiminvestments.com. The Fund’s prospectus and statement of additional information, each dated December 29, 2015, are incorporated by reference into (and are considered part of) this Summary Prospectus.

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 17% of the average value of its portfolio.

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the China All-Cap Index. The China All-Cap Index is designed to measure and monitor the performance of the investable universe of publicly-traded companies based in mainland China (as classified by the S&P BMI County Code classification system). The Index was created by AlphaShares, LLC (“AlphaShares” or the “Index Provider”) and is maintained by Standard & Poor's. The Index includes equity securities of companies of all categories of market capitalizations, as defined by AlphaShares (subject to the minimum capitalization requirements set forth in the China All-Cap Index Methodology).

The Index may include Hong Kong listed securities, including China H-shares and Red Chip shares. China H-shares are issued by companies incorporated in mainland China and listed on the Hong Kong Stock Exchange. Red Chip shares are issued by companies with controlling Chinese shareholders that are incorporated outside mainland China and listed on the Hong Kong Stock Exchange. The Index may also include N-Shares, which are issued by companies based in mainland China and listed on the NYSE Arca, Inc. (“NYSE Arca”) or NASDAQ Stock Market

The Fund will invest at least 80% of its total assets in common stock, American depositary receipts (“ADRs”), American depositary shares (“ADSs”), global depositary receipts (“GDRs”) and international depositary receipts (“IDRs”) that comprise the Index and depositary receipts or shares representing common stocks included in the Index (or underlying securities representing ADRs, ADSs, GDRs and IDRs included in the Index). The depositary receipts included in the Index may be sponsored or unsponsored. 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 2 (the “Trust”) may change the Fund’s investment strategy and other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade 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 Guggenheim Funds Investment Advisors, LLC (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 financial services and telecommunications sectors each represented a substantial portion of the Index.

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

Equity Risk. 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.

China Investment Risk. 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 Chinese companies and the payments of dividends and interest by Chinese companies.

Risk of Investing in Hong Kong. The Fund’s investments which are listed and traded in Hong Kong may expose the Fund to certain legal, regulatory, political, currency and economic risks. China is Hong Kong’s largest trading partner, both in terms of exports and imports. Any changes in the Chinese economy, trade regulations or currency exchange rates may have an adverse impact on Hong Kong’s economy. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region of the People’s Republic of China under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. There is no guarantee that China will continue to honor Hong Kong’s autonomy, and China may change its policies regarding Hong Kong at any time. Any attempt by China to tighten its control over Hong Kong’s political, economic or social policies may result in an adverse effect on Hong Kong’s economy. Hong Kong is located in a part of the world that has historically been prone to natural disasters such as earthquakes and flooding and is economically sensitive to environmental events. Any such event could result in a significant adverse impact on the Hong Kong economy.

Foreign Investment Risk. The Fund’s investments in or exposure to non-U.S. issuers 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, 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. The Fund will not enter into transactions to hedge against declines in the value of the Fund’s assets that are denominated in a foreign currency.

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 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.

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.

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.

Limited Exposure Risk. China A-Shares and China B-Shares are not eligible for inclusion in the Index, even if they would otherwise qualify under the other criteria set forth in the Index methodology. China A-Shares are subject to substantial restrictions on foreign investment, while the China B-Share market generally is smaller and offers less liquidity than the categories of securities which may be included in the Index. However, by excluding such shares from the Index, the exposure provided by the Index (and thus the Fund) to the Chinese presence in the sector may be more limited than would be the case if the Index included China A-Shares or China B-Shares.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of ADRs, GDRs and IDRs. 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 and IDRs 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, GDRs and IDRs 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, GDRs and IDRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs, GDRs and IDRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. Securities of these companies present additional risks because their earnings are less predictable and they are more likely than larger companies to have narrower product lines, markets or financial resources. 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. 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 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 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. Further, the securities held by the Fund may be traded in markets that close at a different time than the NYSE Arca. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when NYSE Arca is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the Shares' NAV is likely to widen. 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.

Passive Management Risk. Unlike many investment companies, the Fund is not “actively” managed. Therefore, it would not necessarily sell a security because the security’s issuer was in financial trouble unless that security is removed from the Index. 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. Even though no single security weight may exceed 5.0% of the Index at the time of each annual rebalance, changes in the market value of the Index’s constituent securities may result in the Fund being invested in the securities of individual issuers (and making additional such investments in the case of creations of additional Creation Units) in greater proportions. 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 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.

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

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

The Fund will issue and redeem Shares at NAV only in a large specified number of Shares called a “Creation Unit” or multiples thereof. A Creation Unit consists of 100,000 Shares. The Fund generally issues and redeems Creation Units principally in-kind. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund.Individual Shares of the Fund may only be purchased and sold in secondary market transactions through brokers. Shares of the Fund are listed for trading on NYSE Arca and because Shares trade at market prices rather than NAV, Shares of the Fund may trade at a price greater than or less than NAV.

If you purchase Shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Investment Adviser or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, the support of technology platforms and/or reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
