个股除权对指数的影响？

指数的编制，是按照成份股票的市值加权算出的。个股除权后虽然股价有所下调，但是股份数量也增加了，市值其实没有变化的，这样算下来，对指数就没有什么影响。不过个股分红后出现股价下调，股票市值是对应减少了...

指数的编制，是按照成份股票的市值加权算出的。个股除权后虽然股价有所下调，但是股份数量也增加了，市值其实没有变化的，这样算下来，对指数就没有什么影响。不过个股分红后出现股价下调，股票市值是对应减少了的，所以个股除息对指数是有影响的。一般个股除息就相当于股价短期下跌会拖累指数，但是拖累的幅度会很小甚至忽略不计，但长期而言所有股票都分红除息，指数可能就一直面临向下折价的压力。

然而，除了分红还有增发、配股等，增发和配股相当于增加了个股市值，短期可以提高指数，但幅度同样很小可以忽略，但长期而言所有股票都增发配股，指数可能就一直有向上溢价的空间。综合算下来，由于非业绩因素导致的个股市值增减对股市的影响是存在的，但是具体影响多大没有明确统计，如果不考虑增发配股等因素，个股除权除息对指数的影响可以近似看做指数里面没有包含个股分红的收益率，也就是说指数并不完全反映了个股的真实收益率，计算指数的回报率时还应该加上指数整体的股息率。

However, who has the willpower to actually sit through a self-imposed MCSE training.
