A tactical Materials-sector strategy: ride uptrends with XLB, flip to inverse SMN when the sector looks overheated, and in downtrends mostly hold SMN unless conditions look washed‑out. One ETF at a time; checked and rebalanced daily.

What it trades: XLB = a fund that owns U.S. materials stocks (chemicals, metals, packaging). SMN = an inverse fund for the same sector; it tends to rise when materials fall (roughly 2× the daily move). RSI: a 0–100 “heat meter” (>70 = overheated, <30 = washed‑out). Steps: 1) Check the trend with moving averages (strong, moderate, mild up; or down). 2) In uptrends, hold XLB, but if RSI says XLB is overheated, briefly flip to SMN to fade the spike. 3) In downtrends, prefer SMN, unless XLB looks washed‑out (or SMN is too hot)—then hold XLB. All-in on one fund, reviewed daily.

Out-of-sample edge: ~31.9% annualized return vs SPY ~17.9%; Sharpe ~1.19 vs ~1.02; max DD ~13.2% vs ~18.8%; Calmar ~2.42; beta ~0.17. Disciplined trend/mean-reversion in materials with stronger risk-adjusted upside than the S&P 500.
