About
A cautious, rules-based switch between SPY (stocks) and SHY (short‑term Treasuries). It owns stocks only when recent stock volatility is calm and SPY looks “cool” vs SHY; otherwise it parks in SHY. Fifteen small signals vote; equal‑weighted, rebalanced daily.
Every day, 15 small “checks” vote between two funds: SPY (US stocks) and SHY (1–3yr US Treasuries).
- First, each check asks: Are SPY’s recent daily swings over 2–8 weeks calm (under 1%, 1.5%, or 2%)? If not, it picks SHY.
- If calm, it compares a simple “hot vs. cold” score (RSI). Lower RSI = more beaten‑down. It buys whichever has the lower RSI (SPY or SHY).
- Your money is split equally across all 15 votes. Rebalanced daily.
Out-of-sample, this strategy beats SPY on risk-adjusted terms: Sharpe ~1.90 vs ~1.38, Calmar ~1.39, and max drawdown ~13.3% vs ~18.8%. It switches tactically between SPY and SHY to reduce losses in volatility while preserving upside.
