What it means
Earnings season is the stretch of several weeks each quarter when most public companies report their results. In the United States, the season is traditionally kicked off by the big banks, followed by waves of technology, industrial, consumer, and energy companies. Because so many reports land in a short window, it is the busiest period of the year for market news.
Each report is judged against analyst estimates, and the gap between expectations and reality drives the price reaction. A company can grow profits and still fall if it misses the whisper number, while a modest beat with strong guidance can send shares soaring. Management commentary about the coming quarters often matters more than the quarter just ended.
Earnings season also sets the tone for the broader market. When bellwether companies across sectors report healthy demand, it lifts confidence in the economy; a wave of cautious outlooks does the opposite. Volatility tends to run higher during these weeks as thousands of individual verdicts arrive at once.
An example
For illustration, during earnings season a retailer beats revenue estimates but warns that shoppers are pulling back. The stock drops 8% in a day, and analysts immediately cut their forecasts for rival retailers reporting later that week.
