A quarterly sector-rotation mix: mostly buys recent 2‑week losers (aiming for a bounce) plus a small tilt to the 200‑day winner, using Vanguard sector ETFs. About half stays in cash to reduce volatility.

Each quarter it looks at 11 Vanguard U.S. sector funds (Energy, Tech, Health Care, Financials, Real Estate, Utilities, Materials, Industrials, Comm Services, Staples, Discretionary). It buys the 3 worst over the past 14 days (20% total). Another 30%: 80% again to those 3, 20% to the 200‑day winner. The rest sits in cash.

Diversified sector-rotation with a 50% cash buffer offers steadier growth and lower risk. OOS: ~15% annualized return, ~0.85 beta to SPX, max drawdown ~18.6%, Sharpe ~1.01. Potential mean-reversion upside with downside protection.
