S&P 500 Sector Rotation in Standard Regime — Where Leadership Stands

Normal-dispersion tape with selective leadership concentrated in Energy.

US equity sector dispersion remains in a normal regime. The 11 S&P 500 sector ETFs show enough separation to support selective alpha capture, but not the broad dislocation that typically drives a high-dispersion spread environment. The backdrop remains mixed: a narrow leadership cohort against a larger lagging cluster.

Energy is the clearest confirmed leader. Its 5-day relative strength is the strongest in the sector set, 20-day relative strength is also firmly positive, and the recent profile is still accelerating. That leaves Energy as the most convincing area of sustained outperformance, not simply a short-term bounce.

Health Care marks the more important rotation. Its 5-day relative strength has turned positive even though 20-day relative strength remains slightly negative. Improvement is underway, but full structural confirmation is not. We treat that as an early-stage recovery, not established leadership.

Technology and Consumer Staples remain positive participants, but with less tactical thrust than Energy. Broader market positioning remains selective. Most sectors still lag, and leadership remains concentrated rather than expanding.
