About
Daily trend-and-safety switch: in uptrends, split between SPY and tech‑heavy QQQ, tilted to the steadier one. In weak markets, buy QQQ on sharp dips, or SPY if holding up; otherwise park in short‑term T‑bills.
Each day:
1) If SPY’s short-term average price (~1 month) is above its long-term average (~10 months), the trend is up. Hold SPY (S&P 500) and QQQ (tech‑heavy Nasdaq‑100), giving more to the steadier one (lower 100‑day volatility).
2) Otherwise, if QQQ looks oversold (RSI—a gauge of how fast it’s been dropping—reads low), buy QQQ.
3) Else if SPY is above its ~31‑day average, buy SPY.
4) Else hold BIL (1–3 month U.S. T‑bills). Rebalance daily.
Out-of-sample, this strategy delivers clear outperformance: annualized return ~28% vs ~22% for the S&P 500, higher Sharpe (~1.59 vs ~1.39), and lower drawdown (~17% vs ~19%), thanks to trend-following and volatility-aware weights.
