Daily switches between CAOS (tail‑risk ETF) and BIL (T‑bills). If CAOS rose >~2% over the past 7 days, shift to BIL; otherwise stay in CAOS. Tries to capture volatility spikes and park in cash after a pop, but may lag in calm markets.

Two ETFs: BIL = cash-like 1–3 month T‑bills; CAOS = a “tail risk” fund that usually drifts down but jumps in market panics. Each day it checks CAOS’s 7‑day return. If CAOS is up more than about 2% over the last week, it moves 100% into BIL. Otherwise, it holds 100% in CAOS.

Out-of-sample edge with clear risk control: Sharpe 3.15, Calmar 9.7, max drawdown <0.5%, and ~4.7% annualized return. Lower downside and steadier risk-adjusted gains versus the S&P 500, powered by simple CAOS/BIL daily switching.
