Shanghai Composite Index 100 points .

The Shanghai Composite Index is a weighted composite stock price index compiled by the Shanghai ** Stock Exchange, with all the ** listed on the Shanghai ** Stock Exchange as the calculation range and the issuance volume as the weight. The index was based on December 19, 1990, with a base day index of 100 points, and was released on July 15, 1991. The index reflects the stock price movements of all A-shares and all B-shares listed on the Shanghai ** Stock Exchange.

The calculation method is broadly the same as that of the Shenzhen Composite Index, except in the treatment of new shares. The calculation of the Shanghai Composite Index will not be included in the calculation until one month later when there are new shares listed.

There are 40 constituent stocks of China's Shenzhen Component Index, with a weighted composite stock price index of 1,000 points with the issuance as the weight, and the base period is 1994, which is basically the same as the rules for compiling stock indexes in major overseas countries.

**Index. It is generally used to reflect the trend of changes in the macro plane and the ** itself. The principle of its compilation is:

The ratio of the market value of the stock price on the current day to the market value of the stock price on the base date. For example, the benchmark date of the Shanghai Composite Index is set on December 19, 1990.

Today's Real-Time Index Last Day's Closing Index Today's Total Market Cap Last Day's Total Market Capitalization. For example, on February 17, 2003, the total market value of the Shanghai Stock Exchange was 100 million yuan, and the index was points.

On February 18, the total market value of the Shanghai Stock Exchange was 100 million yuan. The calculation reads: 18-day index points.

Feb. 18 is up from Feb. 17.

Component index. On January 3, 1995, the Shenzhen Stock Exchange began to compile the Shenzhen Stock Exchange Component Index and released it to the public in real time on February 20 of the same year. The reason for compiling the constituent index is that 2 3 of the share capital in China's ** are not in circulation, so the comprehensive index reflects the changes in ** is not very scientific, and the constituent index is compiled based on the tradable shares, which has a certain degree of rationality.

That is: "who circulates, who counts".

If you don't understand the basics at all, how can you understand what people say? How can you actually ask people to post everything? The ring of knowledge is one ring after another.

You just need to know that the Shanghai Composite Index has grown from 0 in 1990 to about 2880 now, which is simply understood as the temperature of stir-frying. It's 2880 degrees.
