Claymore Launches Micro-Cap ETF Based on Wilshire Index

Claymore Securities, Inc., an innovator of investment product solutions and a wholly-owned subsidiary of Guggenheim Partners, LLC, today announced the launch of the Wilshire Micro-Cap ETF (NYSE Arca: WMCR), based on the Wilshire US Micro-Cap IndexSM—the marketplace’s Pure and Complete SM micro-cap index. The introduction of WMCR marks the fourth fund in Claymore’s suite of Wilshire-focused ETFs, which also includes the Wilshire 5000 Total Market ETF (NYSE Arca: WFVK), Wilshire 4500 Completion ETF (NYSE Arca: WXSP), and Wilshire US REIT ETF (NYSE Arca: WREI). Claymore is the exclusive provider of ETFs utilizing Wilshire indexes.

“Through our exclusive partnership with Wilshire and our ETF suite, investors now have solutions for both the core and satellite portions of their portfolios that combine the most meaningful features and benefits of ETFs,” said Steven A. Baffico, senior managing director and Head of U.S. Retail Distribution for Claymore Securities, Inc. “Claymore’s new Wilshire Micro-Cap ETF is tied to an index that offers an unbiased and more complete picture of the micro-cap market.”

David Hall, senior managing director, Wilshire Associates Incorporated, the firm that created the index that WMCR is designed to track, noted, “The Wilshire Micro-Cap ETF provides investors an efficient way to gain exposure to a very difficult section of the market to replicate. The introduction of WMCR is the first style or size ETF based on the Wilshire indexes and marks another milestone in our commitment to working with Claymore to deliver a comprehensive suite of world-class Wilshire ETFs.”

Prior to today, the Wilshire Micro-Cap ETF’s name was Claymore/Sabrient Stealth ETF (NYSE Arca: STH) and it sought to replicate an index called the Sabrient Stealth Index. WMCR now seeks investment results that correspond generally to the performance, before fees and expenses, of an equity index called the Wilshire US Micro-Cap Index (“Wilshire Micro-Cap”). The Wilshire Micro-Cap is a rules-based index comprised of, as of July 31, 2010, approximately 1,597 securities of micro-capitalization companies, as defined by Wilshire Associates Incorporated. It is a float-adjusted, market capitalization-weighted index of the issues ranked below 2,500 by market capitalization of the Wilshire 5000 Total Market IndexSM.

RISK CONSIDERATIONS

Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money, including the entire principal amount that you invest. Equity Risk: The value of the 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. 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. In addition the funds are subject to Non-Correlation Risk, Concentration Risk, Replication Management Risk, Issuer-Specific Changes, and Non-Diversified Fund Risk. As with any investment, you should consider how your investment will be taxed. The tax information contained in the prospectus is provided as general information. Investors should consult their own tax professional about the tax consequences of an investment as Claymore Securities, Inc. does not offer tax advice. Please read the Fund’s prospectus for more detailed information on these risks and considerations.
