A rules-based switcher among cash, S&P 500 (and 3×), tech (3×), short S&P, and a volatility hedge. It buys dips, trims euphoria, and uses bond‑vs‑bear and trend checks to decide when to be risk‑on or in cash.

It rotates between a few funds based on simple signals. - BIL = T‑bills (cash). SPY = S&P 500. SPXL = 3× S&P. TECL = 3× tech. SH = short S&P. VXX = volatility hedge. - Uses “hot/cold” scores (RSI: 0–100 speed-of-move gauge). Very hot (>80) ⇒ VXX+BIL; very cold (<30/31) ⇒ SPXL/TECL. - Trend check: above 200‑day avg ⇒ own SPY/SPXL. - Safety check: if bonds (BND) look stronger than a bear fund (SH), stay risk‑on; else sit in BIL. Big one‑day pops/drops in TQQQ can trigger brief defense.

Out-of-sample annualized return ~41% vs 15% for the S&P, with a higher Sharpe (~0.90 vs ~0.86) and Calmar ~1.03. Combines hedges, cash, and strategic leverage to boost returns while keeping risk in check; drawdowns can approach 40%.
