Ｌ ｉｓ Ｂ (145A.T) quant model fit
Median hit rate and return when a model selected Ｌ ｉｓ Ｂ (145A.T). Model: ml-factor-lgbm-9f-jp-growth. Model–stock fit, not a buy signal.
Median LONG hit rate is 0.51 (n=12). near a coin flip.Median LONG return is -58.6 bps.
Model predictability decomposition: measures how accurately the ml-factor-lgbm-9f-jp-growth model family predicts this stock's returns within the jp-listed universe. High hit_rate_long does NOT mean 'good stock to buy' -- it means 'the model historically predicted this stock well when selecting it LONG'. This is a property of model-stock fit, not intrinsic stock quality.

| Selection rate · SHORT | 0.0003 | 0.0001 – 0.0022 | 12 |
Hit rate ≈ 0.5 means the model's picks on this stock were near coin-flip. Returns in bps per trade (1 bps = 0.01%). Metrics with n = 0 are omitted.
