Why are the constituent stocks of the ChiNext index adjusted?

The purpose of setting up the GEM constituent stocks is to comprehensively reflect the development of the GEM market, so there will be certain criteria when selecting sample stocks, but due to market changes or operational problems, some listed companies cannot meet the corresponding conditions, so the GEM index will be partially adjusted so that all sample stocks can meet the standards.

On June 1, 2010, the Shenzhen ** Stock Exchange officially compiled and released the ChiNext index with the purpose of comprehensively reflecting the market situation of the ChiNext market, providing investors with more tradable index products and financial derivatives of the subject matter, promoting the index ** products and enriching the variety of market products, and there are 5 shortlisted criteria for index selection

Of course, the "SSE 50" index is also a kind of scale index, which refers to the overall situation of the 50** stocks with a large market size in the Shanghai Stock Exchange.

The industry index actually represents the overall situation of a certain industry. For example, the "CSI 300 Pharmaceutical" represents the industry index, which is composed of 17 pharmaceutical and health industries** in the sample stocks of the CSI 300 Index, reflecting the overall performance of companies in this industry**.

The overall situation of the theme (such as artificial intelligence, new energy vehicles, etc.) is expressed by thematic indexes, and the related indices are "technology leaders", "new energy vehicles", etc.

A shares, officially known as RMB ordinary**, are ordinary shares issued by companies registered in China, listed in China, with face value marked in RMB, and available for subscription and trading in RMB by domestic institutions, organizations or individuals (from 1 April 2013, residents of Hong Kong, Macao and Taiwan in China can open A-share accounts). The official name of the B share is RMB Special**.

It is a foreign stock with a face value marked in RMB, subscribed and traded in foreign currency, listed and traded on the ** exchange in China (Shanghai, Shenzhen), and the place of registration and listing of a B-share company is in China.

So far, the ChiNext Index, the Shenzhen Stock Exchange Component Index, and the SME Board Index together constitute the core index reflecting the listing of the Shenzhen Stock Exchange.

GEM **** starts with 300, such as: Pathfinder **** is: 300005.

The GEM index is based on the starting date as a benchmark point, and the stock price of the day is calculated one by one according to the circulating market value of all ** on the GEM, and then the weighted average is compared with the "benchmark point" on the opening date.

The Shanghai Composite Index and the Shenzhen Component Index exclude the SME Board and ChiNext.

The two major indices are actually what we usually call the main board market, the Shanghai Stock Exchange starts with 600, the Shenzhen Stock Exchange starts with 000, the SME Board starts with 002, and the Growth Enterprise Market starts with 300, each with its own index system, just like Dow Jones, NASDAQ, and Standard & Poor's, these are all different index systems.

As for the B-shares, which are commonly said to be China**, which can be bought by foreign currency investors, this is a product of a specific historical period, and it is not uncommon for foreign listings to be listed now, so the investment value of B-shares is slowly being weakened, and due to the liberalization of QIF (foreign institutional investment), B-shares are gradually being marginalized.

What is GEM?

The GEM, also known as the second board market, is a type of market different from the main board market, which is designed to provide financing channels and growth space for entrepreneurial enterprises that cannot be listed on the main board for the time being. GEM is an important supplement to the main board market and occupies an important position in the capital market. China's GEM listed companies start with "300".

Compared with the main board market, the listing requirements of the GEM are often more relaxed, mainly reflected in the requirements of establishment time, capital scale, medium and long-term performance, etc.

The biggest feature of the GEM market is that it has a low threshold for entry and strict requirements for operation, which helps potential small and medium-sized enterprises to obtain financing opportunities. Companies listed on the GEM market have high growth potential, but they tend to be established for a short period of time, with smaller scale and less outstanding performance, but there is a lot of room for growth. It can be said that the GEM is a low-threshold, high-risk, and strictly regulated market, and it is also a cradle for incubating entrepreneurial and small and medium-sized enterprises.

GEM refers to the fact that it is calculated by selecting some constituent stocks, and it is the selection of 100 sample stocks as the index target (currently based on the top 100 stocks). The ChiNext Composite is the same as the calculation method of the Shanghai Composite Index, and all ChiNext ** are used as index targets (there are currently 107 of them). Generally speaking, the Entrepreneurship Comprehensive Board Index has a wider range of applications.
