 Overhaul of Shanghai stock indexs establishment method: incorporate it into science and technology innovation board securities to improve the representativeness of index market


According to the Shanghai Stock Exchange, generally speaking, securities listed in new sectors of the securities market usually need to undergo a period of follow-up evaluation before they are considered to be included in the market representative index. Since the listing of the first batch of science and technology innovation board securities on July 22, 2019, the Shanghai Stock Exchange has been continuously tracking and evaluating for nearly a year, and the overall operation of science and technology innovation board is stable. As of the end of May, there are 105 listed companies in the science and technology innovation board with a total market value of 1.6 trillion yuan, which has become an important part of the Shanghai stock market. It is increasingly necessary for science and technology innovation board securities to be included in the Shanghai Composite Index.

The listed companies of science and technology innovation board cover many science and technology innovation enterprises. The inclusion of science and technology innovation board securities can not only improve the market representation of the Shanghai Composite Index, but also further improve the proportion of science and technology innovation emerging industry listed companies in the Shanghai Composite Index, so that the Shanghai composite index can better reflect the structural changes of the Shanghai stock market.

Considering that the revision of the Shanghai composite index involves the adjustment of new shares entry time, science and technology innovation board securities are included into the Shanghai composite index according to the revised rules, which is conducive to ensuring the stability and continuity of the rules of the Shanghai Composite Index.
