⑴ 沪深两市前50大权重股

权重股（weighted stock）就是总股本巨大的上市公司股票，它的股票总数占股票市场股票总数的比重很大，权重就很大，权重股的涨跌对股票指数的影响很大。
权重只在计算股指时有意义，股指是用加权法计算的，谁的股价乘总股本最大谁占的权重就最大 ，权重是一个相对的概念，是针对某一指标而言。某一指标的权重是指该指标在整体评价中的相对重要程度。中国银行、工商银行总市值位列前两位，其涨跌对指数影响较大，小市值公司一个涨停也许对指数只带来0.01点的影响，工商银行涨停，指数上涨60点。这就是权重股。

2 工商银行1.27
3 建设银行1.00
4 农业银行1.00
5 中国银行0.96
