Our quantitative rating is based on a variety of historical fundamental and pricing data and represents our opinion of a stock's risk-adjusted performance relative to other stocks.

However, it does not incorporate all of the factors that can alter a stock's performance.

For those reasons, we believe a rating alone cannot tell the whole story, and should be part of an investor's overall research.
