摘要
本文实证检验了上证180和深成指的指数调整效应。发现上证180指数效应逐步凸现,但其价格效应和成交量效应并没有一致性。深成指作为我国历史最长的成份股指数,受到的关注更加广泛,其指数效应也更加明显,但在指数调整后的一段时间后价格发生了反转,说明指数效应的影响是短期的,并不持续。
Case studies of Shanghai 180 and Shenzhen Component reveal an increasing impact of Shanghai 180, with no correlation between its price and trading volume. Shenzhen Component is more popular due to its long history and therefore is accepted on a wider basis. In the period after the adjustment of component stocks of both indices, stock prices reversed, an indication of their short- termi mpact.
