复权是指对股票进行除权后的一种特殊处理方法，它考虑到了股票在除权前后的价格和数量变化，从而对股票的价格进行修正。在股票除权后，由于股本增加或送股等原因，股票的数量会增加，但价格会下降。复权方法通过将除权前后的价格和数量进行综合处理，从而修正股票价格，使其能够真实反映公司价值和市场表现。

复权的方法有多种，包括前复权、后复权、无复权等。前复权是指将除权前的价格和数量作为基准，对除权后的价格进行修正；后复权是指将除权后的价格和数量作为基准，对除权前的价格进行修正；无复权则是指不对股票价格进行修正。

复权对于投资者的决策具有重要意义。通过复权处理，投资者可以更加准确地了解股票的真实价值和市场表现，从而做出更加明智的投资决策。例如，在判断股票的历史走势和未来走势时，如果不进行复权处理，投资者可能会得到不准确的信息，从而误导投资决策。

总的来说，复权是一种对股票进行除权后修正价格的技术手段，它可以帮助投资者更加准确地了解股票的真实价值和市场表现。
