ヤマシンフィルタ (6240.T) quant model fit
Median hit rate and return when a model selected ヤマシンフィルタ (6240.T). Model: ml-factor-lgbm-9f-jp-growth. Model–stock fit, not a buy signal.
Median LONG hit rate is 0.72 (n=12). above a coin flip.Median LONG return is +107.7 bps.Above a coin flip is still not a buy signal.
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.
Accuracy (median across grid)
| metric | median | p25 – p75 | n |
|---|---|---|---|
| Hit rate · LONG | 0.7154 | 0.5592 – 0.8202 | 12 |
| Hit rate · SHORT | 0.9512 | 0.9152 – 0.9831 | 12 |
| Avg return · LONG (bps) | 107.7 | 24.8 – 197.9 | 12 |
| Avg return · SHORT (bps) | 200.3 | 177.6 – 291.8 | 12 |
| Selection rate · LONG | 0.0004 | 0.0003 – 0.0010 | 12 |
| Selection rate · SHORT | 0.0019 | 0.0017 – 0.0026 | 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.
