The thesis
Channel-pullback is a mean-reversion strategy dressed in trend-following clothing. It waits for a confirmed uptrend, then buys pullbacks to the lower regression channel or a volume support level, aiming to exit near the upper channel or overhead resistance. The logic is sound in principle: you are trying to buy strength on temporary weakness rather than catch falling knives. The 24-name universe is large-cap and liquid — mega-cap tech (AAPL, MSFT, NVDA), financials (JPM, BAC, V, MA), staples (PG, KO, WMT) and healthcare (JNJ, UNH) — which keeps slippage assumptions honest.
Backtest performance
Over 451 days the strategy returned 7.62% (4.19% CAGR), ending at $10,761 on a $10k base, with a Sharpe of just 0.40 and a max drawdown of 14.83%. The win rate is a low 39.39% across 137 trades — acceptable for a strategy that lets winners run to the upper channel, but it means the equity curve leans on a handful of good exits. The standout red flag is turnover of 2,311%: this book churns aggressively. Fees were modest here ($137 total), but that level of activity makes the strategy sensitive to any real-world cost or spread assumptions.
Validation: did not pass
Walk-forward validation is where the caution lights come on. Across four folds, three were positive, and out-of-sample returns held at 3.63% with a respectable OOS Sharpe of 0.74. But the folds are wildly inconsistent: fold 2 (Jan–Jul 2025) lost 11.42% at a Sharpe of -1.70, while fold 3 (Jul–Dec 2025) surged 20.68% at a Sharpe of 3.86. That dispersion is the story — the strategy's edge is regime-dependent, not steady.
The probabilistic metrics confirm it. The Probabilistic Sharpe Ratio of 0.702 is decent, but the Deflated Sharpe Ratio of 0.196 — which penalises for the 7 trials run — is far below the confidence we require. Validation failed, and rightly so: after accounting for selection effort, we cannot be confident the Sharpe is genuinely positive.
Recent live activity
Despite failing validation, the strategy is flagged live and trading a paper book. Recent runs have been sparse: most scheduled sessions executed zero trades, with single fills on 2026-08-26, 08-27, and 09-02 (a sell of 31 BAC at $62.48). Live activity has centred on AAPL, with several round-trip swing trades between roughly $308 and $315. The account total sits near $9,599 — slightly below its $10k starting point, a reminder that the live result has not yet matched the backtest.
Verdict
Channel-pullback has a coherent thesis and a plausible OOS Sharpe, but the failed deflated-Sharpe gate, low win rate, high turnover and regime-sensitive folds all argue for keeping it on a short leash. Watch fold-2-style conditions closely before trusting it with real capital.
