Thesis Recap
Channel-pullback operates on a clean, time-tested premise: identify large-cap stocks in confirmed uptrends, wait for price to pull back to the lower regression channel or a volume-supported floor, then enter long and target the upper channel or a known resistance level for the exit. The universe is deliberately concentrated in 24 liquid, well-covered names across tech, financials, healthcare, consumer, and energy — sectors where channel structure tends to hold.
Backtest Snapshot
Over 451 days and 137 trades, the strategy posted a 7.62% total return (4.19% CAGR) with a max drawdown of 14.83% and a Sharpe ratio of 0.40. Win rate came in at 39.39% — below the psychological halfway mark, which is expected for a mean-reversion/momentum hybrid where winning trades are sized to be larger than losing ones. Total fees exactly matched the trade count ($1 per trade flat), and turnover ran at 2,311% annualised, reflecting the strategy's active rotation through its universe.
Final paper equity sits at $10,006.46 as of June 26, up from a $10,000 starting stake — modest but positive.
Cross-Fold Performance
The four-fold walk-forward tells a more nuanced story:
| 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% |
Three of four folds are positive, and Fold 3 is genuinely impressive: a 20.68% return on a 3.26% max drawdown is exactly what this strategy should look like when market conditions cooperate. Fold 2 is the outlier and the one to watch — a 16% drawdown over six months suggests the strategy has real vulnerability in choppy, range-less environments where channel structure breaks down.
Validation Status: Not Yet
The strategy has not passed the formal validation gate. The Probabilistic Sharpe Ratio sits at 0.702 and the Deflated Sharpe Ratio at 0.196 — the latter accounting for multiple trials (7 in this case) and the associated data-snooping risk. With a DSR under 0.50, there is meaningful probability that the backtest edge doesn't survive out-of-sample. The out-of-sample return of 3.63% (Fold 4, Sharpe 0.74) is directionally positive, but one fold isn't sufficient evidence on its own.
Recent Activity
The strategy has been running daily but operating conservatively. The past week saw five consecutive no-trade days, with cash sitting near $1,867–$3,842 depending on position churn. The most recent execution was a 7-share AAPL buy at $279.39 on June 25, with one signal rejected the same day. Before that, a tidy CAT round-trip (bought at $857.78, sold at $912.06 just two days later) and a MSFT entry/exit pair illustrate the short hold times the strategy favors.
Strengths and Risks
Strengths: Clean, rules-based logic with no look-ahead bias. Universe liquidity means fills are reliable at the simulated prices. Fold 3 demonstrates the strategy can compound aggressively when regime conditions align.
Risks: The Fold 2 drawdown is the central concern — a 16% loss in six months suggests the strategy needs a trending, not oscillating, market to work. The sub-0.20 DSR means the edge may be partially fitted. High turnover (2,311%) will amplify friction costs in a live account beyond the $1 flat fee assumed here.
Bottom Line
Channel-pullback is a structurally sound strategy that deserves continued live observation through Fold 5. The OOS Sharpe of 0.74 is encouraging; the validation gate will require the DSR to climb materially, which means either more OOS data or fewer parameter trials. Worth watching — not yet worth scaling.
