Sector Rotation Dynamics
The Money Flow Map
Markets don’t move as one. Money rotates. constantly flowing from sectors that have outperformed into sectors with better risk/reward. Understanding this rotation is essential for timing entries and avoiding lagging positions.
Sector rotation isn’t random. It follows economic cycles, interest rate regimes, and risk appetites in predictable patterns.

Mid Cycle (Expansion)

Rotation Mechanics
Relative Strength Analysis
Compare sector performance to the S&P 500. Sectors showing relative strength deserve attention; those showing weakness require caution.
Momentum Persistence
Rotations don’t happen in a day. Strong sectors typically stay strong for weeks or months. Weak sectors tend to stay weak.
The Lag Effect
By the time rotation is obvious in headlines, it’s often halfway complete. Early detection through relative strength provides the edge.
Trading Rotation
Leadership Following
Identify the leading sectors. Allocate capital proportionally. Reassess weekly.
Contrarian Rotation
When rotation reaches extremes (everyone loves tech, hates utilities), consider mean reversion plays.
ETF Efficiency
Sector rotation is best traded through ETFs (XLK, XLF, XLE, XLU, etc.) rather than individual stock picking.
