# ＹＣＰホールディングス（グローバル）リミテッド　ＪＤＲ (9257.T) — per-stock model accuracy

> Model predictability decomposition: measures how accurately the ml-factor-lgbm-9f-jp-growth model family predicts this stock's returns within the jp-growth 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)

Median LONG hit rate is 0.5640 — above a coin flip — still not a buy signal.

| metric | median | p25 | p75 | n |
|---|---:|---:|---:|---:|
| hit_rate_long | 0.5640 | 0.4993 | 0.6676 | 12 |

| selection_rate_short | 0.0040 | 0.0020 | 0.0079 | 12 |

Hit rate ≈ 0.5 means the model's picks on this stock were near coin-flip. Returns in bps/trade. Metrics with n = 0 are omitted; n < 5 is a thin sample.
