CLV Claymore/Robeco Boston Partners Large-Cap Value Etf

Claymore Securities, Inc. today launched the Claymore/Robeco Boston Partners Large-Cap Value ETF (AMEX: CLV) on the American Stock Exchange. The ETF tracks an index designed to identify a group of stocks that display characteristics that give them the potential to outperform other large-cap value indices, while maintaining strong risk diversification. �The Claymore/Robeco Boston Partners Large-Cap Value ETF allows investors access to a unique, large-cap value Index with an investment selection process that considers a company�s valuation, positive momentum and favorable business fundamentals,� said Christian Magoon, Senior Managing Director, Claymore Securities. �Constituent stocks are chosen through a quantitative process that goes beyond the traditional market cap and style metrics that many large-cap value investors begin and end with.� The Claymore/Robeco Boston Partners Large-Cap Value ETF (AMEX: CLV) seeks investment results that correspond generally to the performance, before the Fund�s fees and expenses, of an equity index called the Robeco Boston Partners Large Cap Value Index. The index is comprised of approximately 100 to 300 equity securities and American depository receipts (ADRs), selected from a universe of over 1,000 stocks, using a quantitative ranking methodology comprised of three factors: attractive valuation, positive momentum and favorable business fundamentals. The index is rebalanced quarterly.

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. Investment Risk: an investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Equity Risk: a principal risk of investing in the Fund is equity risk, which means that the value of the securities held by the Fund will 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. Foreign Investment Risk: the Fund�s investments in non-U.S. issuers, although limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including, among others, greater market volatility than U.S. securities, currency risk and less complete financial information than for U.S. issuers among other risks. 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. Since the Index constituents may vary on a quarterly basis, the Fund�s costs associated with rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of the cash held by the Fund to meet redemptions and expenses. If the 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 of it purchased all of the stocks in the Index with the same weightings as the Index. Replication Management Index: unlike many investment companies, the Fund is not �actively� managed. Therefore, it would not necessarily sell a stock because the stock�s issuer was in financial trouble unless that stock is removed from 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. Portfolio Turnover Risk: the Fund may engage in active and frequent trading of its portfolio securities in connection with the quarterly rebalancing of the Index and therefore the Fund�s investment. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of a year. A high portfolio turnover rate (over 100%) could result in high brokerage costs. While a high portfolio turnover rate can result in an increase in taxable capital gains distributions to the Fund�s shareholders, the Fund will seek to utilize the creation and redemption in-kind mechanism to minimize capital gains to the extent possible. 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. 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. Claymore ETFs are listed on the AMEX the same way as shares of a publicly-traded company. Claymore ETFs can be purchased through most brokerage accounts. They can be bought and sold throughout the day on the AMEX during normal trading hours. The Fund issues and redeems shares at NAV only in large blocks of 50,000 shares (each block of 50,000 shares is called a �Creation Unit�) or multiples thereof. Only broker-dealers or large institutional investors with creation and redemption agreements, called Authorized Participants (�APs�), can purchase or redeem these Creation Units. Investors buying or selling ETF shares on the secondary market may incur brokerage costs and other transactional fees. Shares of ETFs may fluctuate in price due to daily changes in trading volume. At times, shares may not have a high volume of trading. Except when aggregated in Creation Units, Shares are not redeemable securities of the Fund. Investors should consider the investment objectives and policies, risk considerations, charges and ongoing expenses of the ETFs carefully before they invest. The prospectus contains this and other information relevant to an investment in the ETFs. Please read the prospectus carefully before you invest or send money.
