# サンユウ (5697.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-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)

Median LONG hit rate is 0 — below a coin flip.

| metric | median | p25 | p75 | n |
|---|---:|---:|---:|---:|
| hit_rate_long | 0 | 0 | 0.3143 | 11 |
| hit_rate_short (thin n) | 0.7273 | 0.5909 | 0.8636 | 2 |

| avg_return_short_bps (thin n) | -0.6400 | -2.3950 | 1.1150 | 2 |
| selection_rate_long | 0.0053 | 0.0039 | 0.0076 | 12 |
| selection_rate_short | 0 | 0 | 0 | 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.
