Cyclical-vs-Defensive Regime Rotation
tilt between a cyclical and a defensive sector basket driven by a broad-market trend regime
BlackRock flags the unusual 2026 pairing where both cyclicals (energy, materials, industrials) and defensives (staples, utilities) are outperforming tech — "one of these bets is probably wrong." A rules-based regime switch that leans cyclical in uptrends and defensive in downtrends captures this dispersion without forecasting which side wins.
Universe
Cyclical basket (XLE, XLB, XLI, XLF, XLY) vs defensive basket (XLP, XLU, XLV), plus SPY as the regime gauge.
How it works
Monthly, hold the cyclical basket equal-weighted when SPY is above its 200-day moving average (or when cyclicals' 3-month relative strength vs defensives is positive), otherwise rotate to the defensive basket.
Expected performance
Research-derived Sharpe estimate: 0.5–0.9. .
