ミツバ (7280.T) quant model fit
Median hit rate and return when a model selected ミツバ (7280.T). Model: ml-factor-lgbm-9f-jp-growth. Model–stock fit, not a buy signal.
Median LONG hit rate is 0.26 (n=12). below a coin flip.Median LONG return is -140.8 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 · SHORT | 1 | 1 – 1 | 12 |
| Avg return · LONG (bps) | -140.8 | -188.9 – -69.7 | 12 |
| Avg return · SHORT (bps) | 268.3 | 221.5 – 360.3 | 12 |
| Selection rate · LONG | 0.0011 | 0.0010 – 0.0017 | 12 |
| Selection rate · SHORT | 0.0012 | 0.0010 – 0.0015 | 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.
