VPT Divergence (JP Growth Stocks)

slug: vpt-divergence-jp-growth

VPT Divergence (JP Growth Stocks) backtest. Median Sharpe across 144 parameter sets is -0.79. p-value is 0.10. Max DD is -27.2%. Period: 2022-03-01 to 2026-09-01. Best Sharpe +0.31 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

Volume-Price-Trend (VPT) accumulates volume signed by returns; a divergence between the VPT path and the price path is read as hidden accumulation/distribution. Ranking on VPT-price divergence tests whether price subsequently closes the gap.

Why it didn't work

Across 144 grid combinations, median Sharpe=-0.79, best=0.31. Primary failure mode: no_edge.
