Bottom-decile momentum with no quality, value, or sector offset. Not a contrarian setup — breakdown continuation.
Momentum has collapsed into the bottom decile of the universe, quality is below mid (so it's not a high-quality drawdown that contrarians would buy), the sector is confirming the move, and accruals aren't cushioning. The contrarian-bottom and deep-value patterns explicitly screen this case OUT via their quality/accruals gates — this pattern catches the rejected residual.
Jegadeesh-Titman 1993 (Returns to Buying Winners and Selling Losers) is one of the strongest published anomalies: the bottom decile of 6-12 month momentum continues underperforming over the following 3-6 months in the absence of value or quality offsets. Brock-Lakonishok-LeBaron 1992 confirmed the technical-breakdown signal on traditional moving-average crossovers.
Mean reversion does eventually catch up — the bottom-decile momentum cohort tends to flip bullish over 24-36 month horizons (De Bondt-Thaler reversal). The pattern is a tactical bearish signal, not a multi-year position. Watch for a regime flip to risk-on or a quality stabilisation as exit signal.
