Sharp one-week gains are often exits rather than entries. Our sealed backtest measured peer-relative 6-month outcomes, not one-week moves, and the model as a whole did not pass its precision gate; treat this table as a watchlist, not a signal.

Drops on structurally strong sets are the more interesting side of this table. In our sealed backtest the 6-month drawdown relative to peers was the one feature consistently signed across folds; the model as a whole did not pass its precision gate, so read these as research candidates, not calls.
