A daily switch. If the market’s fear gauge is running hot, take a 3× short on the S&P 500. Otherwise, hold the two calmest among Apple 1.5×, Microsoft 1.5×, NVIDIA, and AMD based on recent volatility.

Each day: - Check VIXM, an ETF linked to market fear/volatility. If its 40‑day RSI (a speed/heat meter) > 69, buy SPXU, a fund targeting 3× the opposite of the S&P 500. - Otherwise, split equally between the two least‑volatile (past 10 days) among: AAPU (Apple 1.5×), MSFU (Microsoft 1.5×), NVDA, AMD. Rebalance daily.

Out-of-sample: 25.5% annualized return vs 22.9% for the S&P, with a Calmar ~0.55 and a built-in risk-off hedge (SPXU) during spikes. Note: max drawdown can reach ~46%.
