The thesis
Channel-pullback is a trend-continuation strategy with a mean-reversion entry. It waits for a confirmed uptrend, then buys the pullback to the lower regression channel or a volume-support level, aiming to exit at the upper channel or resistance. The idea is to pay less for exposure you already believe in — enter on weakness within strength, rather than chasing breakouts. It runs across a 24-name large-cap universe spanning tech, financials, healthcare, staples and energy (AAPL, MSFT, NVDA, JPM, JNJ, XOM, and peers).
Recent activity
The strategy has been in a holding pattern. Across the six scheduled runs from 13–20 October, most executed nothing: four of six logged "0 executed," with single trades on the 14th (buy NVDA, 9 shares at $220.45) and 16th (sell JNJ, 7 shares at $255.37). As of the 20 October run, the book held $9,058.22 in cash against a total of $11,010.59 — a heavily defensive, cash-dominant posture. Earlier October trades show the pattern more clearly: a tidy PFE round-trip (bought 71 at $27.83 on the 8th, sold at $28.17 on the 9th) alongside trims in KO, CVX, XOM and MA. This is a strategy currently finding few qualifying setups and sitting on its hands — appropriate discipline if entries genuinely aren't there, but worth watching that it isn't simply stalled.
Backtest and validation
The headline backtest covers 451 days: +7.62% total return, 4.19% CAGR, Sharpe 0.40, and a 14.83% max drawdown across 137 trades. The win rate is a low 39.39% — meaning profitability depends on winners being materially larger than losers, consistent with a let-the-trend-run design. Turnover is high at 2,311%, so execution quality and fees matter; the run booked $137 in fees with no FX cost.
The more sobering story is in validation, which did not pass. Three of four walk-forward folds were positive, but the dispersion is the concern:
- Fold 1: +6.53% (Sharpe 1.25)
- Fold 2: −11.42% (Sharpe −1.70)
- Fold 3: +20.68% (Sharpe 3.86)
- Fold 4: +3.63% (Sharpe 0.74)
Out-of-sample return averaged 3.63% at a 0.74 Sharpe — respectable, but propped up by the standout fold 3. The deflated Sharpe ratio of 0.196 (against a PSR of 0.702, across 7 trials) is the red flag: once you account for multiple testing, the edge is statistically thin and could plausibly be noise.
Strengths and risks
Strengths: the entry logic is sound in trending regimes (fold 3 shows what it can do), drawdowns are moderate, and the current cash-heavy stance suggests the model respects its own filters rather than forcing trades.
Risks: fold 2's −11.42% drawdown period reveals the core vulnerability — when the assumed uptrend breaks, "buying the pullback" becomes catching a falling knife. The failed validation and near-zero DSR mean we should treat the backtest return as optimistic. For now, channel-pullback earns continued observation on a small allocation, not conviction sizing.
