Ａｐｐｉｅｒ Ｇｒｏｕｐ (4180.T) quant model fit
Median hit rate and return when a model selected Ａｐｐｉｅｒ Ｇｒｏｕｐ (4180.T). Model: ml-factor-lgbm-9f-jp-growth. Model–stock fit, not a buy signal.
Median LONG hit rate is 0.62 (n=12). above a coin flip.Median LONG return is +72.6 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.

| metric | median | p25 – p75 | n |
|---|---|---|---|

| Avg return · LONG (bps) | 72.6 | 51.7 – 93.2 | 12 |
| Avg return · SHORT (bps) | -16.2 | -119.5 – 36.5 | 12 |
| Selection rate · LONG | 0.0054 | 0.0047 – 0.0063 | 12 |
| Selection rate · SHORT | 0.0006 | 0.0004 – 0.0009 | 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.
