What Is Sector Rotation and Why Does It Matter?
Sector rotation describes changes in relative performance or allocation among industry sectors as economic and market conditions change. Historical cycle frameworks associate some sectors with expansion, peak, contraction, or recovery phases, but timing and leadership are not predictable and can differ materially from prior cycles.

How to Use Sector Rotation in Your Portfolio
- Compare classifications: Review how ETF price changes differ across sectors.
