NEW YORK, Dec. 15 /PRNewswire/ -- The American Stock Exchange(R) (Amex(R)) today announced that it has launched trading in four new exchange traded funds (ETFs) from Claymore Securities, Inc. (Claymore). The four new Claymore ETFs give investors an opportunity to invest in the first ETF to track an index based on the value of corporate intellectual property, the first ETF of stocks that are more likely to perform well in weak market conditions, the first ETF to capture the spin-off effect and an ETF that tracks diversified environmentally-responsible companies. These ETFs are each based on different equity indexes from Ocean Tomo, Sabrient Systems LLC, Clear Indexes LLC and Light Green Advisors, LLC. "The Amex is proud to be working with Claymore on these unique ETF offerings," said Cliff Weber, Senior Vice President of the ETF Marketplace. "Claymore has created innovative products that offer investors new opportunities. We are pleased to have been selected to list these four new exchange traded funds." Claymore/Ocean Tomo Patent ETF (OTP) OTP seeks investment results that correspond generally to the performance of the Ocean Tomo 300(TM) Patent Index and is the first ETF to invest in an index based on the value of corporate intellectual property. The index, which is priced and published by the Amex, identifies those companies across the style and capitalization spectrum with the highest ratio of patent value to book value, as determined by Ocean Tomo's PatentRatings(TM) System. This diversified market-weighted index is comprised of 300 common stocks, selected from a broad universe of U.S.-traded stocks, which own valuable patents. Claymore/Sabrient Defender ETF (DEF) DEF seeks investment results that correspond generally to the performance of the Sabrient Defensive Equity Index and is the first defensive equity ETF to offer the potential upside of the equity markets while seeking to reduce the downside risks associated with equity investing. The index is designed to identify companies with potentially superior risk/return profiles as determined by Sabrient Systems LLC during periods of weakness in the markets and/or the American economy overall. The index is comprised of approximately 100 stocks selected, based on investment and other criteria, from a broad universe of U.S.-traded stocks and American Depository Receipts ("ADRs"). Claymore/LGA Green ETF (GRN) The Claymore/ LGA Green ETF is based on the Light Green Advisors Eco* Index(TM). The index is comprised of approximately 225 stocks selected, based on investment and other criteria from a broad universe of U.S.-traded stocks and ADRs with representation from all economic sectors. Claymore/Clear Spin-Off ETF (CSD) CSD seeks investment results that correspond generally to the performance of the Clear Spin-off Index and is the first ETF to track companies that have been spun off from larger companies. Spin-off companies historically have been able to focus more on their core business and thus unlock their true market value. This process can be described as the spin-off effect. The index is designed to identify companies with potentially superior risk/return profiles, as determined by Clear Indexes LLC, that have been spun-off from larger corporations and have the opportunity to outperform, on a risk-adjusted basis, the Russell Midcap(R) Growth Index and other small-cap-oriented benchmark indexes. The specialist for the four new exchange traded funds is Goldman Sachs Execution & Clearing, LP. The specialist for the options on the four ETFs is LaBranche Structured Products, LLC.
