Strategy Thesis
Channel-pullback targets large-cap equities from a 24-name universe — tech, financials, healthcare, consumer staples, energy, and industrials — entering when price retraces to the lower regression channel or volume-supported floor within a confirmed uptrend. The exit rule is symmetric: close near the upper channel or at a defined resistance level. It is a classic mean-reversion-within-trend setup, optimized to avoid catching falling knives by requiring trend confirmation before any entry.
Backtest Snapshot
Over 451 days and 137 trades, the strategy returned 7.62% on a starting equity base, finishing at $10,761.52 and implying a CAGR of roughly 4.2%. That headline number is soft. The Sharpe ratio of 0.40 sits well below the 1.0 threshold most practitioners treat as a floor for live deployment. The maximum drawdown of 14.83% is more than twice the return itself — a ratio that raises questions about how much risk is being taken per unit of gain.
Win rate clocks in at 39.4%, which is not alarming for a trend-following/pullback hybrid — these strategies typically make money on the size of winners, not their frequency — but it puts extra pressure on average win/loss ratios that are not visible in the aggregate data. Turnover of 2,311% per year is high and suggests the strategy is entering and exiting positions frequently, making fee drag a real concern even at $1 per trade.
Walk-Forward Validation: Mixed Picture
The four-fold walk-forward splits the picture sharply:
| 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 the standout — a near-perfect environment for pullback strategies, with a Sharpe of 3.86 and a drawdown of just 3.26%. Fold 2 is the mirror image: a −11.42% loss in a regime that likely featured sharp breakdowns where pullbacks to channel support did not hold. Three of four folds are positive, but the depth of the one negative fold heavily erodes the aggregate.
The validation formally did not pass. The Probabilistic Sharpe Ratio of 0.702 means there is roughly a 30% chance the observed Sharpe is noise. The Deflated Sharpe Ratio of 0.196 — which adjusts for the number of trials (7) — is the harder verdict: after accounting for the search over parameter combinations, the edge shrinks to near-zero on a risk-adjusted basis.
Recent Live Activity
Live paper-trading has been subdued. The most recent executed trades were a buy of 9 shares of NVDA at $204.82 and a close of 2 shares of CAT at $912.06 on June 12, both during the same scheduled run. The CAT round-trip — bought at $857.78 on June 10, sold at $912.06 two days later — is a clean example of the thesis working as intended: enter at channel support, exit near resistance for a ~6.3% gain on that position. The prior week also included a quick MSFT entry at $427.54 and exit at $400.31, a losing trade that illustrates the strategy's vulnerability when channel support breaks outright.
The June 15–16 runs show zero executions, with roughly $3,739 in cash against a $10,404 portfolio — about 36% cash. The strategy is being selective, which is appropriate given current market noise, but also means it may be missing opportunities.
Assessment
Channel-pullback demonstrates a real edge in trending, low-volatility regimes (Fold 3 is compelling evidence). The concern is regime dependence: when the market environment shifts — particularly into sharp sell-offs — the strategy can suffer outsized drawdowns relative to its steady-state returns. The failed DSR gate is the honest signal here: with seven parameter trials and a modest Sharpe, the observed results are not yet statistically separable from a lucky run. This strategy warrants continued live observation with constrained position sizing rather than full capital deployment.
