The thesis
Channel-pullback is a trend-aligned dip-buyer. It buys pullbacks to the lower regression channel or volume support within confirmed uptrends, then exits at the upper channel or overhead resistance. In other words, it is not a contrarian bottom-fisher — it only leans into weakness when the broader trend is already pointing up. The tradable universe is 24 large-cap U.S. names spanning tech (AAPL, MSFT, NVDA), financials (JPM, V, MA), healthcare (UNH, JNJ), and staples (KO, PG, WMT, COST).
Recent activity
The strategy is live and trading on a scheduled daily cadence. Over the last week it has stayed busy but disciplined: runs from July 10 through July 17 executed between one and six trades each, with zero rejections across the window. Recent fills show the pullback-and-exit rhythm in action — buying KO at $81.44 and adding AAPL twice ($315.56, then $327.54 sold the next day), while trimming PG, COST, DIS, and WMT into strength. Total account equity has hovered tightly around $10,000 (from $10,182 on July 10 to $10,024 on July 17), so recent P&L has been essentially flat rather than trending.
Backtest performance
Over 451 days the backtest returned 7.62% (final equity $10,761), a 4.19% CAGR. The headline numbers are honest-but-unspectacular: a 0.4 Sharpe, a 14.83% max drawdown, and a 39.39% win rate across 137 trades. A sub-40% win rate that still produces positive returns tells a clear story — the average winner is meaningfully larger than the average loser, which is consistent with a strategy that cuts pullbacks that fail and rides the ones that resume the trend.
The one figure that deserves scrutiny is turnover of 2,311%. That is a lot of churn for a 7.62% gross return, and while modeled fees here are light ($137 total), real-world slippage on that many round-trips could erode a non-trivial slice of the edge.
Validation: it did not pass
Walk-forward validation returned passed: false, and the fold detail explains why. Three of four folds were positive, but the dispersion is severe:
- Fold 1 (Aug 2024–Jan 2025): +6.53%, Sharpe 1.25
- Fold 2 (Jan–Jul 2025): −11.42%, Sharpe −1.70
- Fold 3 (Jul–Dec 2025): +20.68%, Sharpe 3.86
- Fold 4 (Dec 2025–May 2026): +3.63%, Sharpe 0.74
Most of the full-period return is carried by a single blockbuster fold. Strip out Fold 3 and the picture is far less flattering. The out-of-sample return of 3.63% (OOS Sharpe 0.74) is respectable but thin, and the deflated Sharpe ratio of 0.196 — against a PSR of 0.702 and 7 trials — signals that the in-sample Sharpe is not robust once you adjust for multiple testing.
Verdict
Channel-pullback has a coherent, defensible thesis and a live track record of clean, low-rejection execution. Its edge, though, is fragile: heavily dependent on one favorable regime, dragged by a deeply negative 2025 fold, and flagged by its own validation gate. Worth keeping live and observed — not yet worth sizing up.
