Following a period of protracted decline in economic activity, a recovery occurs when business activity is increasing. This is viewed primarily with increases in Gross Domestic Product (GDP) and employment levels. As businesses increase their sales and are more confident about future activity, they hire more people. The new hires are more confident about their future and spend a portion of their income on business, and the cycle continues. The stock market usually leads an economic recovery, because stock investors look to the future. If investors see an economic recovery 12 months from now, they will start to accumulate shares in companies that will benefit.
