ジンジブ (142A.T) quant model fit
Median hit rate and return when a model selected ジンジブ (142A.T). Model: ml-factor-lgbm-9f-jp-growth. Model–stock fit, not a buy signal.
Median LONG hit rate is 0.23 (n=12). below a coin flip.Median LONG return is -277.9 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.

| metric | median | p25 – p75 | n |
|---|---|---|---|
| Hit rate · LONG | 0.2331 | 0.1894 – 0.2576 | 12 |
| Hit rate · SHORT | 0.9180 | 0.8241 – 0.9899 | 12 |
| Avg return · LONG (bps) | -277.9 | -312.2 – -101.3 | 12 |
| Avg return · SHORT (bps) | 448.7 | 398.5 – 645.1 | 12 |
| Selection rate · LONG | 0.0100 | 0.0080 – 0.0127 | 12 |
| Selection rate · SHORT | 0.0053 | 0.0025 – 0.0077 | 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.
