群馬銀行 (8334.T) quant model fit
Median hit rate and return when a model selected 群馬銀行 (8334.T). Model: ml-factor-lgbm-9f-jp-growth. Model–stock fit, not a buy signal.
Median LONG hit rate is 0.37 (n=12). below a coin flip.Median LONG return is -60.6 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.

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. Rows marked thin n have fewer than 5 observations — do not over-read them.
