SAN ANTONIO, June 2 /PRNewswire/ -- South Texas Money Management, Ltd. has been named in the "Top Guns" ranking of Informa Investment Solutions (IIS) in the six star category. The six star ranking is derived from investment performance for the five-year period ended March 31, 2009.

The database that South Texas Money Management was measured in, called the Planned Sponsor Network (PSN), is used by investment professionals to evaluate and select managers nationally. The peer group for South Texas Money Management in this ranking is Domestic All-Cap Core Equity Managers.

"This has been a very challenging environment for investors and managers so we are very pleased with this recognition," said Jeanie Wyatt, CFA, CEO and Chief Investment Officer of South Texas Money Management, Ltd. "I am particularly proud of this ranking because it is based on long term performance. Our portfolios include stocks of large, mid and small capitalization companies in the U.S. as well as international companies. We also balance growth stocks and value stocks. Diversification is our number one rule in investing. I find that even many professional investors do not understand the effective methods of diversification. It can reduce volatility. That is important."

Today, STMM's managed assets total approximately $1.4 billion and the company has over 50 employees that include research analysts, fixed income and equity managers and investment advisors. STMM, with offices in San Antonio, Austin, Dallas, and Houston, currently manages assets for individuals, foundations, trusts, estates, employee benefit plans and endowments.

In presenting its performance results, STMM claims compliance with the Global Investment Performance Standards (GIPS), which are a voluntary set of standards developed by the CFA Institute and based on the fundamental principles of full disclosure and fair representation. This claim of compliance is verified quarterly by an independent third party consultant. For a complete presentation/composite description that adheres to the GIPS standards, contact South Texas Money Management.

* The peer group of All-Cap Core Equity Managers was created using information collected through the PSN investment manager questionnaire and uses only gross of fee returns. In the event net of fee returns had been used, the rankings may have come out differently. The All-Cap Core Equity peer group includes domestic equity investment products for which managers responding to the PSN manager questionnaire selected "core" as the primary equity style and "All-Cap" or "no primary capitalization" as their primary capitalization range. REIT and convertible products are excluded. The peer group of All-Cap Core Equity Managers is comprised of 117 managers who reported to the PSN database and 157 investment products. Investment products must have an R-Squared of 0.80 or greater relative to the style benchmark (S&P 500 Index) for the recent five-year period. Moreover, investment products must have returns greater than the style benchmark for the three latest three-year rolling periods. IIS selects only the investment products which standard deviation for the five-year period is equal or less than the median standard deviation for the peer group. The top ten information ratios for the latest five-year period then become "6 Star Top Guns." The information ratio is an efficiency measure calculated by dividing the Excess Rate of Return by the Standard Deviation of the Excess Rate of Return stream (Tracking Error). PSN database information is intended for use by qualified investment professionals. Past performance is not indicative of future results. There is a possibility of loss.
