"Shenzhen Stock Exchange Index" is selected as the Shenzhen Stock Exchange Index, which means that the company has developed from a local listed company into a listed company with representative industry growth, stable return on investment to shareholders, better social responsibility for environmental protection and positive recognition by market investors.

Calculation method of Shenzhen Component Stock Index:

Take the stocks of 5 listed companies with market representativeness as samples from all the stocks listed on Shenzhen Stock Exchange, take the circulating share capital as the weight, calculate by the weighted average method, take July 2, 1994 as the base date, and set the base date index as 1 points.

This is a constituent stock index compiled by Shenzhen Stock Exchange. It is a weighted stock index calculated by taking the shares of 4 listed companies with market representativeness as the calculation object and taking the tradable shares as the weight, which comprehensively reflects the stock price trend of A and B shares listed on Shenzhen Stock Exchange.

Extended information:

"Shenzhen constituent stock index" compiled reason:

Shenzhen constituent stock index was compiled due to the defects of the comprehensive index. In terms of actual operation and reflecting the actual operation state of the stock market, the Shenzhen Composite Index has the following obvious defects:

1. It is not reasonable to use the total share capital as the weight. At present, China stock market is only an individual stock market, and neither state shares nor legal person shares can be listed and circulated. If the total share capital is used as the weight, it is easy to produce deviation.

2. The IPO impact index is lower.

3. The structure changes frequently. Every time a new stock is listed, it is included in the index calculation, from the initial 5 to 142 when the constituent stock index is compiled. The influence of each stock on the index is decreasing, the internal structure is changing, and the comparability before and after the index is not strong.

4. There is deviation in the adjustment calculation during ex-rights. Because the total share capital is used to calculate the ex-dividend price, if the dividend schemes of state shares, legal person shares and individual shares are different, this ex-dividend price is often not an effective indicator for individual shares, and it will be biased when used to calculate the index. Sometimes the right to fill the stock will make the index fall; However, the weighted stocks made the index rise.

It is precisely because of the above defects in the Shenzhen Composite Index that the Shenzhen Stock Exchange began to compile the Shenzhen constituent stock index on January 3, 1995, and released it in real time on February 2 of the same year.
