A bear‑market hedge: usually in T‑Bills, but when the S&P 500 breaks its long‑term trend it tactically shorts (or occasionally goes long) the Nasdaq using leveraged ETFs, guided by “hot/cold” readings and trend filters.

Purpose: a bear‑market hedge that mostly parks in BIL (cash‑like T‑Bills). Brakes: if markets look very hot (>79) or very weak (<30) on a 0–100 short‑term heat meter (RSI), stay in BIL. Switch: if SPY (U.S. stocks) falls below its 200‑day average, it tactically shorts or (sometimes) goes long the Nasdaq using PSQ/SQQQ (−1x/−3x) or QQQ/TQQQ (+1x/+3x). A 20‑day trend check and whether Treasuries (TLT/IEF) look stronger than the short fund guide the side. Two similar signals are blended, favoring the steadier one. Daily rebalance.

Out-of-sample: ~33.6% annualized vs ~18.2% for S&P, Sharpe ~1.34 vs ~0.98, drawdown ~13.9% vs ~18.8%. Mostly cash, with disciplined Nasdaq hedges in downturns—stronger upside, better downside protection.
