Daily, rules-based switching. Above SPY’s 200‑day average: buy the two most oversold funds or hedge with volatility (UVXY) when markets are too hot. Below it: play oversold rebounds, or rotate among UVXY, inverse QQQ (SQQQ), or short‑term bonds.

Step 1: Trend check. If the S&P 500 (SPY) is above its 200‑day average (a long-term trend line), it’s “risk‑on.” Otherwise it’s “risk‑off.” Step 2: Short‑term meter (RSI). RSI is a 0–100 “hot‑or‑cold” gauge. >~80 = very hot; <~31 = very cold. Risk‑on: If the market looks very hot, hold UVXY (a volatility spike play). Otherwise buy the two funds that fell the most recently (mean‑reversion) from a menu of leveraged tech/semis/S&P/small‑caps/financials plus a few defensive bond/commodity choices. Risk‑off: If things look washed out, try quick rebounds in 3× tech or 3× S&P. If volatility is surging, hold UVXY (or, if extreme, pick inverse QQQ or short‑term bonds). If vol is calm, toggle among 3× Nasdaq up (TQQQ), 3× Nasdaq down (SQQQ), or short‑term bonds based on short‑term trend and RSI.

Adaptive regime-switching strategy targets higher long-run gains than the S&P 500. Out-of-sample annualized return: 42.5% vs 24.1% for SPY, with favorable risk-adjusted metrics (Calmar ~0.86) despite larger drawdowns.
