# ＰＩＬＬＡＲ (6490.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 0.5727 — above a coin flip — still not a buy signal.

| metric | median | p25 | p75 | n |
|---|---:|---:|---:|---:|
| hit_rate_long | 0.5727 | 0.3304 | 0.7467 | 12 |
| hit_rate_short (thin n) | 1 | 1 | 1 | 2 |
| avg_return_long_bps | -57.8 | -140.6 | 27.6 | 12 |
| avg_return_short_bps (thin n) | 116.7 | 116.7 | 116.7 | 2 |
| selection_rate_long | 0.0003 | 0.0002 | 0.0004 | 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.
