Understanding Sector Rotation

Sector rotation is the tendency of money to flow from one industry sector to another as the economy moves through its cycle of expansion, peak, contraction, and recovery.

The Idea

Different sectors perform better during different economic phases:

• Early recovery: Financials and consumer discretionary tend to lead as confidence returns
• Mid-expansion: Technology and industrials often perform well as businesses invest in growth
• Late expansion: Energy and materials may benefit from rising demand and commodity prices
• Contraction: Defensive sectors like healthcare, utilities, and consumer staples tend to hold up better because people need their products regardless of the economy

Why It Happens

Investors anticipate where profits will grow next and shift capital accordingly. This creates a rotating pattern of sector outperformance.

Practical Note

Sector rotation is observed historically, but it is not a precise, predictable clock. Cycles vary in length and magnitude. Many factors beyond the economic cycle — technology shifts, regulation, global events — also influence sector performance.

For Learning

Understanding sector rotation helps explain why different parts of the market lead at different times, rather than everything rising or falling together.
