52-Week High Momentum
Based on George & Hwang (2004) research. Stocks near their 52-week highs tend to outperform due to investor underreaction (anchoring bias). Enter when price reaches 95% of 52-week high, exit when falling below 85%.

Score and risk profile
Each bar is a percentile against every strategy on the same market and window (100 = best).
How it held up in sell-offs (SPY)
| Period | Strategy | Buy & hold |
|---|---|---|
| Q4 2018 sell-off | -17.5% | -19.2% |
| COVID crash (Feb–Mar 2020) | -31.3% | -33.7% |
| 2022 bear market | -16.4% | -24.5% |
| Market above its 200-day average (annualized) · 81% | +12.0% | +12.5% |
| Market below its 200-day average (annualized) · 19% | -4.9% | +19.8% |
Sell-off dates follow the US stock market. Above/below the 200-day average uses the previous day's position, so there is no look-ahead.
Out-of-sample check (SPY)
| Check | Value |
|---|---|
| Chosen parameters on their 3-year training windows (average Sharpe) | 0.81 |
| Same parameters in the following 6 months, when traded (Sharpe) | 0.76 |
| Default parameters over the same months (Sharpe) | 0.82 |
| Parameter re-selections / changes | 28 / 5 |
| Parameter settings with a positive Sharpe (full history) | 6 of 9 |
| Sharpe across settings: worst / median / best | 0.00 / 0.66 / 0.75 |
Out-of-sample periods start on 2013-01-04. Training-window figures are flattered by picking the best of 9 settings; the out-of-sample figure is what the strategy actually earned. A large drop, or a result that depends on one setting, points to overfitting. How walk-forward testing works.
