股价是买卖方博弈的结果。一般来说，高涨之后股票会下跌，超跌之后的股票会反弹。超跌反弹一般涨几天？超跌反弹如何选股？相信这是不少朋友关心的问题。
1.超跌反弹是什么意思
超跌反弹就是股票下跌的程度超过正常范围而产生的上涨行情。当然，这种行情不是持续很长时间的，而是一个短暂行情。
超跌反弹
在恰当的时机抓住超跌反弹的股票，对于股民来说是一个不错的机会。因为超跌意味着股民进场的股价低，一旦上涨获利的空间大。不过，前提是你能分辨得出股票是不是处于超跌反弹阶段。
2.超跌反弹一般涨几天
通常而言，超跌反弹持续时间是一两个星期。但需要具体个股具体分析，有些个股反弹的时间会较短，比如几个交易日；有些个股反弹的时间会长一点，比如十几个交易日。
然而，当超跌的股票上涨到一定程度之后，因为看空情绪的影响，卖方多于买方，股价会掉头下跌。因此，超跌反弹最重要的是抓住时机。一旦超跌反弹之后追涨风险就增大了。
3.超跌反弹如何选股
选择超跌反弹的股票需要注意：1、必须是严重超跌的，违背正常行情的；2、有技术指标佐证的；3、看成交量。股价上涨的同时，成交量也跟着增加。但成交量不能太过于离谱。如果成交量大幅度下滑，超跌反弹可能就要进入尾声了。
