How it held up in sell-offs (SPY)

PeriodStrategyBuy & hold
Q4 2018 sell-off-6.8%-19.2%
COVID crash (Feb–Mar 2020)-1.4%-33.7%
2022 bear market-12.0%-24.5%
Market above its 200-day average (annualized) · 81%+3.6%+12.5%
Market below its 200-day average (annualized) · 19%+16.0%+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)

CheckValue
Chosen parameters on their 3-year training windows (average Sharpe)0.87
Same parameters in the following 6 months, when traded (Sharpe)0.69
Default parameters over the same months (Sharpe)0.81
Parameter re-selections / changes28 / 13
Parameter settings with a positive Sharpe (full history)9 of 9
Sharpe across settings: worst / median / best0.61 / 0.69 / 0.73

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.
