ML Factor 12f-Quality with Meta-Label Filter (JP Growth Stocks)

slug: ml-factor-lgbm-12f-meta-label-jp-growth

ML Factor 12f-Quality with Meta-Label Filter (JP Growth Stocks) backtest. Median Sharpe across 54 parameter sets is +1.08. p-value is 0.15. Max DD is -19.5%. Period: 2024-07-01 to 2025-06-30. Best Sharpe +3.03 is not the representative figure.

Verdict: marginal. Some parameter set has a p-value under 0.10, but the median itself misses promising (Sharpe > 0.5 and p-value < 0.05). Primary reason: no_edge. It is not regime, frequency, or cost, and the median does not clear the bar.

Hypothesis

Combining H1's 12f-quality features (sharpe_60d, max_dd_60d, price_r2_60d) with H4's meta-label P(win) filter produces synergistic improvement: better features yield better base scores, and meta-label filters more accurately on higher-quality inputs. Phase 2c showed 12f-quality (Sharpe 1.28) and meta-label 0.55 (Sharpe 1.16) independently improve over 9f-base (0.58), but the combination is untested.

Why it didn't work

Across 54 grid combinations, median Sharpe=1.08, best=3.03. Primary failure mode: no_edge.
