Business Cycles

Understanding business cycles is fundamental for investment advisers. The economy doesn't grow in a straight line—it expands and contracts in recurring patterns that profoundly affect client portfolios, asset allocation decisions, and investment recommendations.

What Is a Business Cycle?

A business cycle is the natural fluctuation in economic activity over time, measured primarily through changes in Gross Domestic Product (GDP). These cycles are inevitable and have occurred throughout modern economic history, though they vary significantly in duration and severity.

The economy moves through four distinct phases, each with characteristic features that investment advisers must recognize to serve clients effectively.

The Four Phases of the Business Cycle

1. Expansion

The expansion phase represents economic growth and is typically the longest phase of the cycle.

Investment Implications: During expansions, cyclical stocks (consumer discretionary, industrials, technology) typically outperform. Corporate earnings grow, and risk appetite increases among investors.

2. Peak

The peak is the high point of economic activity before the economy turns downward. It represents maximum economic output but also maximum risk of overheating.

Warning Signs at Peaks:

• Labor shortages and rising wages
• Asset bubbles forming (real estate, stocks)
• Excessive leverage in the financial system
• Inverted yield curve (short-term rates exceeding long-term rates)

3. Contraction (Recession)

The contraction phase represents economic decline. A recession is technically defined as two consecutive quarters of declining GDP—though the National Bureau of Economic Research (NBER) uses broader criteria including employment, income, and spending.

A depression is a severe, prolonged contraction—technically defined as six consecutive quarters (18 months) of declining GDP. The Great Depression of the 1930s is the primary historical example.

4. Trough

The trough is the lowest point of economic activity before recovery begins.

In Practice: How Investment Advisers Use This Knowledge

Understanding business cycles helps advisers make better recommendations:

During Late Expansion/Peak:

• Review client portfolios for excessive equity exposure
• Consider shifting toward defensive sectors (utilities, consumer staples, healthcare)
• Evaluate bond duration—shorter duration protects against rising rates
• Discuss risk tolerance with clients who may have become overconfident

During Contraction/Trough:

• Reassure clients that cycles are normal and recovery will come
• Look for opportunities to rebalance into depressed assets
• Consider cyclical stocks that historically lead recoveries
• Evaluate high-yield bonds as spreads widen

Economic Indicators: Predicting and Confirming Cycles

Investment advisers and economists use three categories of indicators to understand where the economy stands in the cycle:

Leading Indicators (Predict Future Activity)

Leading indicators change direction before the economy does:

Coincident Indicators (Current Activity)

Coincident indicators confirm what's happening right now:

Lagging Indicators (Confirm Trends)

Lagging indicators change direction after the economy turns:

On the Exam

The Series 65 exam tests your ability to:

1. Identify the four phases of the business cycle and their characteristics
2. Classify indicators as leading, coincident, or lagging
3. Understand the relationship between monetary/fiscal policy and cycles
4. Apply cycle knowledge to investment recommendations
5. Know key definitions: recession (2 quarters declining GDP), depression (6 quarters)

Expect 2-3 questions on business cycles. Common question types include:

• "Which is a leading indicator?"
• "During which phase would an adviser recommend..."
• "A recession is defined as..."

Key Takeaways

• Business cycles have four phases: expansion, peak, contraction, and trough
• Recession = two consecutive quarters of negative GDP growth
• Depression = six consecutive quarters of negative GDP growth
• Leading indicators predict future activity; lagging indicators confirm past trends
• Investment advisers should adjust recommendations based on cycle position
• The stock market itself is a leading indicator
• Understanding cycles helps advisers set appropriate client expectations
