The national stock market team refers to a collection of specialized investment institutions composed of state capital and government funds. Its main purpose is to protect the national capital security and promote the stability and development of the stock market. The national stock market team is usually composed of state-owned banks, financial institutions and national investment funds, all of which have strong investment ability and long-term stable investment planning.

The emergence of the stock market national team is mainly to stabilize the stock market and avoid the excessive impact of market fluctuations on the whole economy. Its main functions include holding stocks, increasing the liquidity of the capital market, regulating market sentiment and enhancing market confidence. In some special periods, the national team will directly intervene in the stock market and change the relationship between supply and demand in the market by buying or selling stocks on a large scale, thus adjusting the stock market fluctuation.

Although the main purpose of the national stock market team is to maintain the stability of the capital market, there are also certain risks and challenges. The large-scale trading of stocks by the national team will have an impact on market transactions and may lead to market fluctuations. In addition, the national team's actions may cover up the real risks of the stock market and give the market an illusion. Therefore, the national stock market team needs to use it flexibly according to the actual situation and strictly control risks in order to better achieve the set goals.
