About
Trend-first crash‑avoidance system. Own SPY only when multiple long‑term trends are up. Otherwise hide in Treasuries/staples; in deeper selloffs it tactically flips between tech (QQQ/SMH) and short‑QQQ (PSQ/QID) using short‑term strength signals.
Step 1: Is the S&P 500 (SPY) in a strong uptrend? It checks several 50–200 day averages. If yes, hold SPY.
Step 2: If not, go defensive in Treasuries (SHV/IEI) and Staples (XLP). In deeper selloffs it runs a tech module that flips between owning or shorting Nasdaq/semis (QQQ, SMH, QLD, USD vs PSQ, QID) using short‑term “RSI” (a 0–100 recent‑strength score) and 20‑day trends. It may buy XLK on sharp tech dips.
Out-of-sample, this strategy beats SPY on risk-adjusted return and drawdown: Sharpe 1.76 vs 1.45, annualized 28.7% vs 23.2%, max drawdown 10.2% vs 18.8%. A crash-avoidance, trend-first approach with tactical hedges.
