How to read this page

How it’s measured. Scores from Stox rank the stock against about 1,200 S&P 500, Nasdaq-100 and Russell 1000 stocks and popular funds, where 100 is best; market beat and staying power use prices, business growth uses revenue, margins and cash flow. Readings on other dashboards come from this site’s pages.

Scores are percentiles: 80 means the stock ranks above 80% of the others on that measure. They describe the recent past and are not advice or a forecast.

Its type follows Stox Atlas: each of the four scores is split at 50. “Steady” means its rank has held, high or low, so it says nothing on its own about direction.

Its group is the cluster of large US stocks whose prices have moved together over five years, with the market’s own moves taken out. The typical daily move is the average true range over 14 days, a measure of how far the price travels in a day including overnight gaps.
