Research Methodology

TheStreet.com Ratings condenses the available fund performance and risk data into a single composite opinion of each fund's risk-adjusted performance. This allows the unbiased identification of those funds that have historically done well and those that have underperformed the market. While there is no guarantee of future performance, these Investment Ratings provide a solid framework for making informed, timely investment decisions.

The funds listed below have either reached their three year anniversary or are additional share classes of existing funds for which the mutual fund companies have submitted three years of pro-forma results.

Funds rated A or B are considered "Buy" rated based on a track record of higher than average risk-adjusted performance. Funds at the C level are rated as "Hold," while underperformers at the D and E levels our model ranks as "Sell."
