A daily switch that uses a “heat” gauge on tech to flip among cash (BIL), leveraged S&P 500 (SPYU), semiconductor bull/bear funds (SOXL/SOXS), or volatility (UVXY). It buys trends when calm, fades extremes, and hides in T‑Bills when stress rises.

Each day it reads a turbo‑Nasdaq “heat” gauge (TQQQ). RSI = a 0–100 heat score of recent moves. - If very hot (RSI>79): short semis (SOXS). - After fast drops (~−12% in 6 days): on a big 1‑day rebound buy volatility (UVXY); if very cold (RSI<32) buy semis (SOXL); else hold T‑Bills (BIL). - Otherwise: if trend is up (QQQ above its 25‑day average) and stress is light, ride a 4× S&P 500 note (SPYU); if stress flags trip (big recent drop or jumpy bonds), stay in BIL.

Out-of-sample: ~21.83% annualized return vs SPY ~19.86%, with max drawdown ~42.12% vs ~18.76%. Tech-driven risk-on/risk-off strategy using hedges and cash in stress—higher upside, but larger swings.
