The thesis
Channel-pullback is a classic mean-reversion play dressed for a trending market. It buys pullbacks toward the lower regression channel or volume support within confirmed uptrends, then exits at the upper channel or resistance. The universe is a broad, liquid slice of US large-caps — 24 names spanning tech (AAPL, MSFT, NVDA), financials (JPM, V, MA), healthcare (UNH, JNJ), and staples (PG, KO, WMT). The design intent is sound: only fade dips when the primary trend still favours you.
Recent activity
The strategy is trading actively and cleanly. Across the last six scheduled runs (20–27 Aug), every order executed with zero rejections, and total equity has hovered around $9,400–$9,540. The recent tape is striking for its concentration: nearly every fill is AAPL, cycling in and out in 6-share clips between roughly $308 and $315 — buy the dip, sell the bounce, repeat. UNH, JPM, and CAT make cameo appearances, but AAPL is doing the heavy lifting. That is a coherent expression of the thesis, but it also means the live book is far less diversified than the 24-name universe suggests.
Backtest and validation
Over 451 days the backtest returned +7.62% (final equity $10,761.52), a 4.19% CAGR, with a Sharpe of just 0.40 and a max drawdown of 14.83%. Win rate is a low 39.39% across 137 trades — acceptable only if winners meaningfully outrun losers, which the modest Sharpe suggests they barely do. Turnover is a hefty 2,311%, so fees and slippage are a real, ongoing tax on this style.
The walk-forward picture is the crux. Three of four folds were positive, and fold 3 was genuinely excellent (+20.68%, Sharpe 3.86). But fold 2 lost −11.42% with a −1.70 Sharpe — a reminder that when the uptrend filter fails, buying dips just catches falling knives. Out-of-sample return averaged +3.63% with a 0.74 Sharpe, respectable but thin.
Most importantly: validation did not pass. The probabilistic Sharpe ratio (0.702) is encouraging, but the deflated Sharpe ratio — which penalises for the 7 trials run — collapses to 0.196. Once you account for how many variants were tried, the edge is not statistically distinguishable from luck.
Verdict
Channel-pullback has a defensible thesis and disciplined execution, and it is currently in the black. But the honest read is cautious: a sub-0.5 Sharpe, a sub-40% win rate, a brutal fold-2 drawdown, a failed DSR, and heavy single-name concentration in live trading. Treat it as a promising candidate that needs a stronger trend filter and more robustness before it earns a larger allocation — not a proven engine.
