Thesis
Channel-pullback is a trend-following entry strategy: it waits for a confirmed uptrend, then buys when price retreats to the lower regression channel or a recognised volume-support zone. Exits target the upper channel boundary or a resistance level. The logic is intuitive — enter with the trend, but only after the crowd has already faded. The 24-stock universe spans mega-cap US equities across technology, financials, healthcare, consumer staples, and industrials, providing breadth while keeping execution friction low.
Backtest Overview
Over 451 trading days, the strategy completed 137 trades and delivered a 7.62% total return (CAGR ~4.19%). Turnover was high at 2,311%, reflecting the active entry-and-exit cadence inherent to channel trading. Two metrics stand out as yellow flags:
- Win rate of 39.4% — fewer than two in five trades close profitably. This is structurally common in trend-based systems that use wide channel targets, but it demands generous reward-to-risk on winners to stay solvent. Whether that ratio holds under stress is the central question.
- Max drawdown of 14.83% against a 7.62% total return — the strategy at one point gave back nearly twice its final gain. That ratio leaves little margin for a prolonged losing stretch.
The Sharpe of 0.40 is positive but unexceptional; it sits well below the 1.0 threshold most institutional allocators treat as a starting point.
Walk-Forward Validation
Four sequential folds expose significant regime dependency:
| Fold | Period | Return | Sharpe | Max DD |
|---|---|---|---|---|
| 1 | Aug 2024 – Jan 2025 | +6.53% | 1.25 | 6.16% |
| 2 | Jan 2025 – Jul 2025 | −11.42% | −1.70 | 16.09% |
| 3 | Jul 2025 – Dec 2025 | +20.68% | 3.86 | 3.26% |
| 4 | Dec 2025 – May 2026 | +3.63% | 0.74 | 8.44% |
Fold 3 is exceptional and skews the headline numbers considerably. Fold 2 is the cautionary counterpoint: a 16% drawdown in roughly six months on a strategy meant to trade with the trend suggests the regime-detection component may lag turning points materially. Three of four folds are positive, which is encouraging, but the dispersion is wide.
The Probabilistic Sharpe Ratio (PSR) of 0.702 means there is roughly a 70% chance the true Sharpe is positive — reasonable, but not compelling. More importantly, the Deflated Sharpe Ratio (DSR) falls to 0.196 after adjusting for seven parameter trials. That near-zero figure means the edge could plausibly be the product of fitting rather than a durable signal. The validation gate correctly did not pass this strategy.
Live Activity (1–3 June 2026)
The strategy deployed its full $10,000 allocation on launch day, placing five initial positions including GOOGL, CAT, DIS, JPM, and COST. Over the following two sessions it rotated out of DIS (bought at $101.26, sold at $102.93) and CAT (bought at $860.79, sold at $908.35) while adding UNH and WMT. Portfolio value reached $10,162.17 by end of 3 June, with $1,901.48 held in cash. The 3 June run executed zero trades against two rejections, suggesting the strategy is waiting for qualifying pullback setups rather than forcing entry — a healthy sign of discipline.
Strengths and Risks
Strengths: The thesis is logically coherent and well-suited to the large-cap universe. Fold 4 (the most recent, out-of-sample period) shows a positive return with a 0.74 Sharpe and a contained 8.44% drawdown — the freshest evidence is constructive. Early live behaviour looks orderly.
Risks: The DSR of 0.196 is the headline concern — statistical significance is weak once multiple-testing is accounted for. The 39% win rate and a near-2x drawdown-to-return ratio in the backtest mean the strategy needs its winning trades to be meaningfully larger than its losers; any compression of that ratio (tighter markets, faster reversals) could quickly erode the edge. Fold 2's −11.42% period serves as a live stress scenario to watch for.
