Deep-drawdown bounce (capitulation cohort, no MA dependency)

The result

Code: research/drawdown_bounce.py Report: research/drawdown_bounce_report.json (n=31,399 events)

Strips the MA cross out entirely: fires when a stock is 15 %+ below its trailing 252d high, has been falling for at least 60 trading days since that high, has a negative trailing-20d return, and is showing volume confirmation (5d vol ≥ 1.2x 60d baseline).

Bucket n 60d edge 250d edge
dd_deep (-50% to -30%) 7477 +1.7 % +6.4 %
dd_severe (≤ -50%) 1937 +7.6 % +25.4 %
vol_confirmed + dd ≤ -30% 2654 +3.8 % +12.5 %
OOS 2020+ vol_confirmed + dd ≤ -30% 1545 +4.3 % +18.1 %
IS pre-2020 vol_confirmed + dd ≤ -30% 1109 +2.9 % +3.8 %

Three observations: 1. The bounce is monotonically stronger with deeper drawdown. 2. The death-cross + dd combo earns ~3x the edge of dd alone — the cross does add timing on top of pure drawdown context. 3. n is much larger here than in the cross variant, so this is more practical to operationalise as a basket.
