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.
