After the bell
If the information is released during the day, it can have impact on stock prices. However if it is released after the bell, it can impact only the opening prices on the next working day. Positive information can increase opening price, and negative can decrease it. Therefore closing price can be different from the opening price next day.
The name after the bell comes from tradition on many stock markets, e.g. New York Stock Exchange (NYSE) to ring the bell on the beginning and end of the day. Today the trade is mostly electronic, but the bell is still in use as a symbol.
