老妖股是指那些在股市中具有极高人气和影响力的股票，通常是因为它们在市场上持续表现出色，或者是因为它们具有特殊的题材和概念。这些股票的涨跌往往能够引领整个市场的情绪，因此被称为“老妖股”。

老妖股的涨跌幅度往往很大，有时甚至会出现暴涨暴跌的情况。这是因为这些股票的持有者通常是机构投资者和游资，他们的资金实力和操作手法都与普通投资者有所不同。

在股市中，老妖股往往是比较难以把握的。因为这些股票的价格往往受到多种因素的影响，包括市场情绪、政策变化、行业趋势等等。因此，投资者需要具备较高的技术分析能力和风险控制能力才能在这些股票中获得较好的收益。

但是，对于一些短线交易者来说，老妖股也是一个不错的选择。因为这些股票的波动性较大，所以短线交易者可以通过快进快出的方式来获取短期的收益。

总的来说，老妖股是一种具有极高人气和影响力的股票，对于投资者来说具有一定的挑战性。投资者需要根据自己的实际情况和风险偏好来选择是否参与老妖股的投资。
