52-Week High Momentum (JP Growth Stocks)
slug: high52w-momentum-jp-growth
52-Week High Momentum (JP Growth Stocks) backtest. Median Sharpe across 320 parameter sets is -0.53. p-value is 0.25. Max DD is -39.9%. Period: 2022-05-02 to 2026-09-01. Best Sharpe +0.27 is not the representative figure.
Verdict: rejected. The median reaches neither promising (Sharpe > 0.5 and p-value < 0.05) nor marginal (Sharpe > 0.05 and best p-value < 0.10). Primary reason: no_edge. It is not regime, frequency, or cost, and the median does not clear the bar.

Hypothesis
George & Hwang (2004): proximity to 52-week high as momentum signal. Stocks near their 52-week high continue to outperform. Signal = Close / max(Close, 250d). LONG highest ratio, SHORT lowest.
Why it didn't work
Across 320 grid combinations, median Sharpe=-0.53, best=0.27. Primary failure mode: no_edge.
Facts (5)
Best grid Sharpe ratio is 0.27 (p=0.61).
