Four times a year, public companies open their books. These earnings reports are among the biggest scheduled events that move a stock's price.
Public U.S. companies must report their financial results every quarter (and annually) to the SEC. An earnings report tells investors how much money the company made, how fast it's growing, and what management expects next. It's the core input for fundamental analysis.
Prices move on the gap between results and expectations, not the raw numbers. A company can post record profits and still fall if it missed analyst forecasts or gave weak guidance — and vice versa. This is why a stock can drop 10% on “good” earnings: the good news was already priced in.
The few weeks each quarter when most big companies report is called earnings season. Volatility and trading volume rise as results pour in. Long-term investors care about the trend across many reports; short-term traders try to play the single-day move.

Prices move on results versus expectations. If strong results were already expected and priced in, or guidance disappoints, the stock can still fall.
