Composite of 4 factors below, ranked against the 3132 U.S. stocks BeStock covers.

How this is scored: each factor above is a 0–100 percentile rank against every other stock BeStock covers (or, for Wall Street, against the five-point Strong Buy–Sell scale). The overall grade is the plain average of whichever factors apply to this stock — no factor is weighted more than another. That average maps to a letter: A ≥ 85, B ≥ 70, C ≥ 50, D ≥ 30, otherwise F. Recomputed from the data on this page as prices and filings update — it describes where a stock ranks today, not a forecast, and not a BeStock recommendation to buy or sell.
