Rules-based, short-term tactic: when major stock indexes run too hot, it buys volatility funds (that typically pop if stocks wobble), padded with cash/defensive ETFs. On sharp dips it briefly buys leveraged bulls. With no signal, it holds dividend ETFs.

RSI is a 0–100 “speed‑of‑rise” score: 80+ = too hot, <30 = too cold. When big stock funds (like SPY/QQQ) get too hot, it bets on a quick shakeout by buying volatility funds (VIXY/UVXY) that often jump when stocks slip, plus cash‑like T‑bills (BIL) and defensive ETFs (SPLV/BTAL). The hotter it is—and if volatility itself is warming—the larger the VIX slice. If things get too cold, it briefly buys 3× bull funds (TECL/SPXL). If no clear signal, it parks in dividend ETFs (SCHD/DGRO). It also checks other broad/sector funds for the same cues.

RSI-driven tactical strategy trims risk with cash/defenses and volatility hedges to exploit short-term mean reversion. Out-of-sample: max drawdown 3.88% vs SPY 5.07%, Calmar 2.25, beta ~0.47—delivering steadier, risk-adjusted gains versus the S&P 500.
