Yes.

In addition, CSI 300 and Science and Technology 50 are also very important indexes.

The SSE 50 Index selects the 50 most representative stocks with large scale and good liquidity in the Shanghai securities market to form sample stocks based on scientific and objective methods to comprehensively reflect a group of high-quality large-cap companies with the most market influence in the Shanghai securities market.

overall condition.

SSE 50 Index, the index abbreviation is SSE 50, the index code is 000016, and the base date is December 31, 2003.

The existing SSE index system includes SSE (Composite) Index, SSE 180 Index, SSE A-Share Index, SSE B-Share Index and 5 industry classification indices.

Among these indexes, the Shanghai Stock Exchange (Composite) Index has the greatest influence. However, since the market began to undergo profound adjustments in 2001, due to the adjustment of stock price structure, the differentiation between high-quality stocks and low-quality stocks has become increasingly prominent, and the value has grown.

The rise of ideas has further exacerbated this differentiation.

Judging from the actual situation in 2003, as of December 26, the Shanghai Composite Index rose by 11.5% compared with the end of the previous year.

However, if the 66 new stocks listed since 2003 are deducted, the index actually rose by only 5.58% compared with the end of 2002.

In view of the above-mentioned index blurring problem, it is necessary to launch a new component stock index.

The existing 180 index, together with Shenzhen's 100 index***, constitute the value center of the two cities.

However, whether from the experience of mature markets or from the actual needs of the country, this classification is still rough. Therefore, it is very necessary to launch the Shanghai Stock Exchange 50 component stock index in a timely manner.

Judging from the situation of the 50 constituent stocks of the SSE, it has the following characteristics: First, the net profit and total profit of the 50 SSE constituent stocks in the third quarter of 2003 accounted for 42.06% and 43.05% of all A-shares in the same period respectively, which is an outstanding example of high-quality blue chip stocks.

Representative; secondly, overall, the 50 constituent stocks of the SSE have better liquidity than the 180 constituent stocks of the SSE, and can more accurately reflect the market performance of high-quality large-cap blue-chip stocks; thirdly, the market performance since 2003

, the average increase of the 50 constituent stocks is 28.86%, the largest increase is 108.19% of Shanghai Automobile Co., Ltd., and the smallest increase is -34.96% of Hafei Shares. The difference in individual stock market performance is still large; fourth. Among the 50 constituent stocks, in the third quarter,

The number of stocks heavily held by funds reached 35, accounting for 70%.

It can be said that the SSE 50 will become synonymous with value blue-chip stocks and a weather vane reflecting the positions of mainstream institutions.

For investors, they should closely focus on the company's future profit expectations and the prosperity of the industry in which it operates, as well as whether the company's stock price in the secondary market fully reflects its fundamental changes and other factors to grasp the company selection and purchase and sale timing.

In order to obtain maximum benefits.

Since the 50 constituent stocks of the SSE are all large companies and most lack growth potential, the SSE 50 Index is not the best choice for investors who expect to share in the rapid growth of listed companies (the stocks with better growth potential among the SSE 50 constituent stocks may only be

several or even less), most of the companies with good growth are small companies, and most of these companies have a total market value of less than 10 billion yuan. According to data on August 4, 2011, the lowest market value of the 50 constituent stocks of the Shanghai Stock Exchange is

More than 27.9 billion yuan.
