Sector Rotation: Tech Leads as Dispersion Normalizes

Dispersion sits in a normal regime near its 60-day average. Technology Select Sector SPDR® Fund leads; Materials Select Sector SPDR® Fund gains ground.

US equity sector dispersion across the 11 S&P 500 sector ETFs sits in a normal regime, with a z-score of 0.35 near its 60-day average. Positive dispersion velocity marks a standard rotation backdrop, leaving selection breadth available but not broad-based.

Technology Select Sector SPDR® Fund leads the cross-section and is the confirmed leader. Its 5-day relative strength is firmly positive, its 20-day relative strength ranks 1st, and recent velocity is accelerating. Consumer Discretionary Select Sector SPDR® Fund and Health Care Select Sector SPDR® Fund also sit in the leading quadrant, but both register as secondary leaders against Technology’s stronger short-horizon impulse.

Materials Select Sector SPDR® Fund turns higher from a lagging base and marks the clearest early rotation, with 5-day relative strength inflecting above zero against slightly negative 20-day relative strength. Industrial Select Sector SPDR® Fund shows a similar but smaller improving profile. Defensive and commodity-linked sectors cluster below average on both horizons, forming the lagging pocket.

We favor concentrated exposure to Technology leadership while selectively adding early rotation candidates rather than broad sector beta.
