What the backtest shows

  • Beat buy-and-hold on 2 of 10 markets by annual return over 5 years.
  • Had a smaller maximum drawdown than buy-and-hold on 9 of 10 markets.
  • Best market by Sharpe ratio: GLD (Sharpe 0.81, CAGR 13.0%).
  • Weakest market: ETH-USD (Sharpe -0.33, CAGR -23.4%).
  • Few or no trades in the window on SPY, DBA, UNG — treat those rows as a sign the rules rarely triggered, not as an edge.

How it held up in sell-offs (SPY)

PeriodStrategyBuy & hold
Q4 2018 sell-off-19.2%-19.2%
COVID crash (Feb–Mar 2020)-33.7%-33.7%
2022 bear market-15.6%-24.5%
Market above its 200-day average (annualized) · 81%+12.0%+12.5%
Market below its 200-day average (annualized) · 19%+4.5%+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)0.93
Same parameters in the following 6 months, when traded (Sharpe)0.84
Default parameters over the same months (Sharpe)0.77
Parameter re-selections / changes28 / 5
Parameter settings with a positive Sharpe (full history)9 of 9
Sharpe across settings: worst / median / best0.70 / 0.74 / 0.78

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.
