Closing price

The closing price of a stock, bond, option, or futures contract is the last trading price before the exchange or market on which it is traded closes for the day.

With after-hours trading, however, the opening price at the start of the next trading day may be different from the closing price the day before.

When a security is valued as part of an estate or charitable gift, its value is set at the closing price on the day of the valuation of the estate.
