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 February 9, 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.

The Fund, using a “passive” or “indexing” investment approach, seeks to replicate, before the Fund’s fees and expenses, the performance of the Index. The Index is designed to measure and monitor the performance of fifty high-yielding global equity securities of companies that engage in various infrastructure-related sub-industries. Index constituents must meet size, listing and liquidity requirements and also be part of the S&P Global BMI Index, which is a rules-based index that measures global stock market performance.

Securities in the Infrastructure Clusters must have a float-adjusted market capitalization (i.e., a market capitalization that is calculated based on the number of shares that are readily available in the market rather than all shares outstanding) greater than $250 million, a three-month average daily value traded of $1 million or higher and be listed on a developed market stock exchange. The top fifty highest-yielding securities that meet these criteria (ranked by 12-month dividend yield) are selected for inclusion in the Index.

The Fund will invest at least 80% of its total assets in common stocks that comprise the Index and depositary receipts representing common stocks included in the Index. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any change in this policy or a material change to the Index. The Board of Trustees (the “Board”) of the 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 generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances, such as: (i) regulatory requirements which may affect the Fund’s ability to hold a security included in the Index, (ii) restrictions or requirements in local markets which may render it infeasible or inefficient for the Fund to purchase or sell a security included in the Index or (iii) liquidity concerns that may affect the Fund’s ability to purchase or sell a security included in the Index, in which the Investment Adviser may choose to overweight another security in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index pursuant to scheduled reconstitutions and rebalancings of the Index. The Fund will concentrate its investments (i.e., hold 25% or more of its assets) in a particular industry or group of industries to the extent the Index is so concentrated. As of the date of this prospectus, the utilities, industrials and energy 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. The value of the equity securities held by the Fund may fall 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 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 have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.

Infrastructure Risk. Companies within one of the Infrastructure Clusters that comprise the Index are subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction and improvement programs, high leverage, costs associated with compliance with and changes in environmental and other regulations, difficulty in raising capital in adequate amounts and on reasonable terms in periods of high inflation and unsettled capital markets or government budgetary constraints that impact publicly funded projects, the effects of economic slowdown or recession and surplus capacity, increased competition from other providers of services, uncertainties concerning the availability of fuel at reasonable prices, the effects of energy conservation policies and other factors.

Other factors that may affect the operations of companies within an Infrastructure Cluster include innovations in technology that could render the way in which a company delivers a product or service obsolete, significant changes to the number of ultimate end-users of a company's products, inexperience with and potential losses resulting from a developing deregulatory environment, increased susceptibility to terrorist attacks, risks of environmental damage due to a company's operations or an accident, and general changes in market sentiment towards infrastructure and utilities assets. Companies operating in an Infrastructure Cluster face operating risks, including the risk of fire, explosions, leaks, mining and drilling accidents or other catastrophic events. In addition, natural risks, such as earthquakes, floods, lightning, hurricanes, tsunamis and wind, are inherent risks in infrastructure company operations.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally 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 the Fund’s investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. 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.

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.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulation, world events and economic conditions may affect the

Energy Sector Risk. The profitability of companies in the energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.

Utilities Sector Risk. Stock prices for companies in the utilities sector are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities and rate caps or rate changes. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. Deregulation may permit certain utility companies to earn more than their traditional regulated rates of return; however, some deregulated companies face greater competition and may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company’s equipment unusable or obsolete and negatively impact profitability.

Depositary Receipt Risk. The Fund may hold the securities of non-U.S. companies in the form of American depositary receipts (“ADRs”), global depositary receipts (“GDRs”) and international depositary receipts (“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. 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.

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% 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, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund.

As of the date of this prospectus, the Fund has not yet completed a full calendar year of investment operations. When the Fund has completed a full calendar year of investment operations, this section will include charts that show annual total returns, highest and lowest quarterly returns and average annual total returns (before and after taxes) compared to the Index and a broad measure of market performance.

The Fund will issue and redeem Shares at net asset value (“NAV”) only in a large specified number of Shares called a “Creation Unit” or multiples thereof. A Creation Unit consists of 50,000 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, Inc. (“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.
