Daily, buy the single 2x fund that’s most “beaten down” among utilities, staples, Treasuries, or gold—and keep the other half in cash. If nothing is weak, it parks in cash-like MINT. Simple mean‑reversion with a built-in cash buffer.

Each day it checks five funds and scores their last ~10 days of ups vs downs. The one with the weakest recent score (most “beaten down”) is picked. The portfolio then holds about 50% cash and 50% of that single fund. If nothing is weak, it likely picks MINT, so you sit in cash-like assets. Uses 2x ETFs (high risk).

Out-of-sample annualized return ~27.6% vs SPY ~15.4%; solid risk-adjusted metrics (Calmar ~4.05, Sharpe ~1.26). A simple 2x rotation into beaten-down defensives with a 50% cash buffer aims for bigger upside while capping risk.
