What Is Business Cycle?
The business cycle describes the natural fluctuations in economic activity that occur over time, consisting of four phases: expansion (growth), peak (maximum output), contraction/recession (decline), and trough (minimum output). During expansion, GDP grows, unemployment falls, consumer spending increases, and business investment rises. At the peak, the economy operates near or above capacity, often generating inflationary pressures. Contraction sees declining GDP, rising unemployment, and reduced spending. The trough marks the lowest point before recovery begins. The National Bureau of Economic Research (NBER) officially dates U.S. business cycles. Since World War II, the average expansion has lasted about 5 years, while recessions average about 11 months. Understanding business cycles is crucial for investment timing, risk management, and policy decisions.
Business Cycle Example

- 2Cyclical stocks like automakers and luxury retailers tend to outperform during business cycle expansions and underperform during contractions.
- 3A portfolio manager rotated into defensive sectors like utilities and healthcare as leading indicators suggested the business cycle was approaching a peak.
