It is not only a barometer of macro-economy, but also has important functions of capital aggregation and resource allocation. Other derivative financial products exist and develop on the basis of the stock market. When the stocks in the stock capital market do not rise, derivative financial products are like rootless trees, lacking the basis of value change, the trading volume decreases, the risk is amplified, and the meaning of existence is almost lost, which is equivalent to zero. This also reminds us that while paying attention to derivative financial products, we can't ignore the cornerstone and root of the stock capital market.

The stock market also has the function of resource allocation. The rising stock market can guide the flow of funds to enterprises with good efficiency and development potential, and realize the optimal allocation of resources. When the stock price does not rise, the flow of funds may be stagnant or disorderly, and those high-quality enterprises that should have been supported by funds may be ignored, resulting in waste of resources and inefficient allocation.The existence and development of derivative financial commodity market is based on the stock market. The stock market provides the pricing basis and trading objects for derivative financial products. If the stock market does not rise, derivative financial products will lose the source of their price changes. For example, stock index futures are futures contracts with the stock index as the target. If the stock index does not rise for a long time, it will be difficult to attract investors and its market value will be greatly reduced.The stock market is an important channel for enterprises to raise funds. By issuing stocks, enterprises can gather idle funds in society for expanding production and developing new technologies. For example, in the early development stage, Tesla icon invested a lot of money in the research and development of electric vehicle technology and the construction of production base through financing in the stock market. The growth of a large number of enterprises depends on the capital supply of the stock market. If the stock market does not rise, the financing ability of enterprises will be limited, and new investment projects may not be started, which will affect the innovation and development of the whole economy.
