Monthly equal-weight momentum: buy SPY, QQQ, or IWM if their 30-day trend is positive; if none qualify, park in BIL cash. A protective, ETF-based approach across large-, tech-, and small-cap equities.

Every month, the model evaluates three broad US equity ETFs for momentum using a 30-day lookback. If SPY has positive momentum, SPY is considered for allocation; if not, QQQ is evaluated; if QQQ is positive, QQQ is considered; if not, IWM is evaluated; if IWM is positive, IWM is considered. If none of them show positive momentum, the strategy parks in BIL (cash-like). All acceptable assets are then weighted equally (wt-cash-equal) and the portfolio is rebalanced monthly. In plain terms: ride the uptrends when they exist among SPY, QQQ, or IWM, and move to cash when momentum is weak or negative. If more than one asset qualifies in a given month, weights are split evenly among them.

Out-of-sample, this strategy rides SPY/QQQ/IWM uptrends with cash fallback, delivering higher risk-adjusted returns (Sharpe ~2.44 vs 1.41), higher annualized gains (~32% vs 29%), and far lower drawdowns (~6.8% vs 13.7%), with beta ~0.28.
