Economic cycle

long term patterns of alternating periods, or stages, of economic expansion (growth) and contraction that affects all aspects of economic health, including gross domestic product (GDP), employment, consumer spending and financial markets. Stock price trends are influenced by alternating periods of expansion and contraction in different ways. Prices in some industrial sectors tend to precede or predict a change in the cycle, while others tend to lag behind. Also, some industry sectors that perform better during one period of the cycle will underperform in another. Also termed Business cycle.
