Sales Growth Rank (JP Growth Stocks)

slug: sales-growth-rank-jp-growth

Sales Growth Rank (JP Growth Stocks) backtest. Median Sharpe across 48 parameter sets is -0.17. p-value is 0.41. Max DD is -8.9%. Period: 2025-01-06 to 2026-09-01. Best Sharpe +1.06 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). Results split across up, flat, and down markets, so the median is not stable.

Hypothesis

Top-line growth is the simplest growth signal retail screens sort on; ranking on year-over-year sales growth tests whether revenue growth alone predicts returns, or is already priced in (the classic growth-factor disappointment).

Why it didn't work

Across 48 grid combinations, median Sharpe=-0.17, best=1.06. Primary failure mode: regime_dependent.

Facts (5)

Best grid Sharpe ratio is 1.06 (p=0.19).
