Opening is the first transaction in each security or commodity when trading begins for the day occurs at what's known as its opening, or opening price. Sometimes the opening price on one day is the same as the closing price the night before. But that's not always the case, especially with stocks or contracts that are actively traded in the after-hours markets.
