computed asof 2026-10-01T02:33:09

Median hit rate and return when a model selected ダイジェット工業 (6138.T). Model: ml-factor-lgbm-9f-jp-growth. Model–stock fit, not a buy signal.

Median LONG hit rate is 0.96 (n=12). above a coin flip.Median LONG return is +93.5 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.

Decomposes ml-factor-lgbm-9f-jp-growth — strategy verdict: marginal. Standalone walk-forward run of the same LightGBM 9-factor family on the jp-listed universe (~4,100 tickers); the referenced record's verdict applies to the jp-growth universe only.
