Each figure is the stock's typical move in a week when the force moved by the stated amount, after accounting for the stock market, with its 90% range beneath. Grey figures could not be told apart from zero. A row is marked a clear difference only when the two 90% ranges do not overlap.

This describes the past, and it is not a forecast. Relationships change, and nothing here is a recommendation to buy, sell or hold any security.
