The thesis
channel-pullback is a mean-reversion-within-trend strategy: it buys dips toward the lower regression channel or a volume-support level, but only when the name is in a confirmed uptrend, and it exits into the upper channel or overhead resistance. In plain terms, it tries to buy strong stocks on temporary weakness and sell them back into strength. The tradable universe is 24 large-cap U.S. names spanning tech (AAPL, MSFT, NVDA), financials (JPM, V, MA), healthcare (UNH, JNJ), and staples (PG, KO, WMT). It is currently live.
Recent activity
The strategy trades sparingly. Over the last week of scheduled runs (2026-07-21 through 2026-07-28) it executed just six orders and rejected none, with total equity hovering in a tight band around $10,000—$10,085 on the most recent run. The 2026-07-28 session was the busiest, closing three long positions at once: PG (13 shares at $150.90), KO (24 at $88.05), and CAT (2 at $834.28). Some of these were clean round-trips: PG was bought at $145.99 on 2026-07-23 and sold at $150.90, and KO was accumulated at $81.44 on 2026-07-17 and exited near $88. A UNH position bought at $419.30 and $420.31 was likewise trimmed at $433.57. The pattern is consistent with the stated exit-into-strength logic.
Backtest performance
Over the 451-day backtest the strategy returned 7.62% (final equity $10,761.52), a 4.19% CAGR, with a 0.40 Sharpe and a 14.83% max drawdown. The win rate is a low 39.39% across 137 trades—unsurprising for a pullback style, where a minority of winners are expected to outrun a larger cluster of small losers. Turnover is heavy at 2,311%, though fees were negligible ($137 total, no FX cost). The headline numbers are respectable but not exciting: the return-to-drawdown ratio is roughly 0.5, and a sub-0.5 Sharpe leaves little margin for slippage or regime change.
Validation: the sobering part
Our walk-forward check returns passed: false, and the fold data explains why. Three of four folds were positive—Fold 1 (+6.53%, Sharpe 1.25), Fold 3 (a standout +20.68%, Sharpe 3.86), and Fold 4 (+3.63%)—but Fold 2 (2025-01-22 to 2025-07-05) lost 11.42% with a -1.70 Sharpe and a 16% drawdown. That single window is enough to drag out-of-sample results down to a 3.63% return, and the deflated Sharpe ratio of 0.196 (against a probabilistic Sharpe of 0.702, over 7 trials) signals that the edge is not robust once we account for multiple testing.
Verdict
channel-pullback is a coherent, low-frequency trend strategy that behaves as designed in most regimes. Its strengths are a clear rule set, disciplined round-trips, and strong performance in trending markets like Fold 3. Its risks are concrete: a heavy drawdown when trends break (Fold 2), a fragile Sharpe, and a validation flag that says the backtest edge may not survive live. We'd keep it running on a small allocation and watch how it handles the next choppy tape.
