About
A daily, one-position market timer that mostly holds SPY. In downtrends it buys XLK if the Nasdaq looks washed-out; otherwise it hedges with SH or PSQ (inverse funds). Uses a 200-day trend line and simple 0–100 momentum scores (RSI).
Daily, it aims to stay in SPY (the S&P 500). Two quick checks can green-light SPY. If not, and SPY is above its 200-day average, stay in SPY. If SPY is below that and the Nasdaq (QQQ) looks washed-out (RSI, a 0–100 momentum score, under 30), buy XLK (tech). Otherwise buy an inverse fund that rises when stocks fall: SH (S&P 500) or PSQ (Nasdaq). IEF/BSV are Treasury bond funds used only as signals. Exposures: broad US stocks, tech, or inverse S&P/Nasdaq.
Disciplined daily SPY overlay with downside protection and a tech-tilt rebound signal. Out-of-sample Sharpe ~1.13, ~18.8% max drawdown, near-SPY exposure—delivering attractive risk-adjusted results vs the S&P 500.
