ERS's Probability Guidance evaluates a stock using four proprietary ratings.
The system selects the metric with the best historic performance for the stock when ratings were at their most favorable.

Ratings are divided into seven ranks: A+ (best), A, B, C, D, E, and F (worst).
A stock with a current rating closer to "A+" indicates a higher likelihood of future gains.

Returns calculated above use data compiled as of the previous market close.
