开盘是指股票或期货的交易开始进行，通常是指在交易日的早上9点钟开始，结束时间为下午3点钟。开盘是股票或期货市场的一个重要的交易时段，因为它的价格走势往往会影响全天的交易价格。

在开盘时，交易所会公布一个开盘价，这个价格通常是根据集合竞价得出的。集合竞价是一种竞价方式，在开盘前的特定时间内，投资者可以自由地报价和交易。交易所会根据一定的规则，将投资者的报价和交易进行撮合，得出一个开盘价。

在股票市场中，开盘价的重要性不言而喻。如果一只股票的开盘价很高，那么它的全天价格往往会在这个价位附近波动。如果开盘价很低，那么全天价格可能会一路下跌。因此，投资者需要密切关注开盘价的变化，以便做出正确的投资决策。
