About
Two SPY trend tests drive risk: both up = 100% SPY; one up = 50% SPY; both down = XLK only if QQQ is extremely oversold (RSI<30), else SHV (T‑bills). Daily rebalanced. Exposure toggles among broad U.S. stocks, Tech on selloffs, or cash‑like bonds.
Each day it runs two trend checks on SPY (the S&P 500 fund): 1) Is SPY above its 85‑day average price? 2) Is its 8‑day fast average above its 200‑day long‑term average? If both say up: hold SPY. If one says up: hold 50% SPY. If both say down: if QQQ (Nasdaq‑100) has a 10‑day RSI below 30 (a 0–100 gauge; <30 = very oversold), buy XLK (Tech). Otherwise park in SHV (short‑term Treasuries). Rebalanced daily.
Out-of-sample edge: annualized return 25.62% vs 22.57%; max drawdown 8.42% vs 18.76%; Sharpe 1.59 vs 1.37; Calmar 3.04; beta ~0.84. A risk-managed trend-rotation strategy aiming for higher upside with less downside than the S&P 500.
