Business Cycle

A period during which business activity reaches a low point, recovers, expands, reaches a high point, decreases to a new low point, and so on.

Business Cycle

The recurring and fluctuating levels of economic activity that an economy experiences over a long period of time. The five stages of the business cycle are growth (expansion), peak, recession (contraction), trough and recovery. At one time, business cycles were thought to be extremely regular, with predictable durations. But today business cycles are widely known to be irregular - varying in frequency, magnitude and duration.

Investopedia Commentary

Since the Second World War, most business cycles have lasted three to five years from peak to peak. The average duration of an expansion is 44.8 months and the average duration of a recession is 11 months. As a comparison, the Great Depression - which saw a decline in economic activity from 1929 to 1933 - lasted 43 months from peak to trough.

business cycle

The somewhat irregular but recurring periods of change in economic activity over time. A business cycle is generally divided into four stages: expansion, prosperity, contraction, and recession. The stage in which an economy operates has a significant impact on a firm's profitability and prospects. This impact is especially severe with respect to firms that experience large swings in sales and profits. Many analysts believe stock prices tend to lead the business cycle. Therefore, it is felt that bull markets begin before a period of expansion and that bear markets begin before a period of contraction.
