US Sector Rotation: Investors Shift Toward Defensives, Cyclicals Lose Momentum
The Iranian crisis is leaving clear marks on the sectoral structure of the S&P 500. Sector rotation analysis — based on data as of March 7, 2026 — shows a market that is still formally in an expansion phase, but with unusual characteristics that warrant attention.
The overall signal remains technically mildly risk-on; however, risk appetite has declined significantly, settling at a modest 0.26, a level suggesting investors are far more cautious than the cycle classification would imply.
The most significant data point concerns market participation: only 36% of sectors display a health score above the neutrality threshold. This means that nearly two-thirds of the market is under pressure — a condition that contrasts with the “expansion” label and suggests ongoing internal deterioration.
Sector dispersion at 33 points indicates a highly selective market (as also observed in the analysis of European equity sectors), where choosing the right sector can make a substantial difference in terms of returns.
Another noteworthy element is rotation speed, measured at 3.27 points, a relatively high level that signals rapid shifts in investor preferences. When capital moves quickly from one sector to another, it often reflects uncertainty about the market’s direction and about the correct interpretation of the macroeconomic environment.
