Short‑biased, tactical system that fades overbought spikes and otherwise stays in T‑bills. Uses inverse Nasdaq/S&P and volatility when signals fire; falls back to Treasuries, dollar, or gold in risk‑off regimes. Daily rebalanced.

Daily trend check on the S&P 500. If it’s in an uptrend, only bet against short, “too hot” spikes (RSI is a 0–100 hot/cold meter) via SQQQ/SPXS (bearish stock ETFs) or UVXY (volatility). If not, mostly hide in T‑bills (BIL/SHY/SHV/STIP), with occasional flips to TLT (long Treasuries), UUP/UDN (US dollar up/down), or UGL (leveraged gold) based on simple momentum/RSI. Rebalances daily.

Out-of-sample, this tactical short-biased strategy outperforms the S&P: 23.9% vs 16.6% annual return, Sharpe 1.18 vs 0.84, Calmar 2.17, max drawdown ~11% vs ~19%, with hedging and cash-like protection in risk-off regimes.
