First, financing channels, securities investment funds objectively have the demand for financing through the money market. Open-end funds have to face the subscription and redemption of fund shares at any time. When there is a huge redemption and the fund assets are difficult to be realized within the specified time, there will be a more urgent temporary capital demand. Second, hedging instruments, the securities market itself has great risks. Objectively, it is required to provide funds with some effective hedging instruments to avoid risks, help funds avoid risks and improve the stability of fund operation. Judging from China's current securities market, securities investment funds can't sell short, there is no stock index futures for investment, and there is a lack of hedging tools to avoid risks, which makes it difficult to avoid risks, especially systemic risks. When the market bears for a long time, most funds are hard to cope with. Thirdly, law and supervision, the operation of securities investment funds needs a set of scientific and perfect laws and regulations to regulate the behavior of relevant parties of securities investment funds, and at the same time, it also needs to establish a strong regulatory agency to implement supervision according to law. Fourthly, the development of fund investors and securities investment funds largely depends on the demand of fund investors for this financial tool. V. Fund Talents: As a new industry in China, the securities investment fund industry has accumulated a large number of professionals after several years of development. However, according to the development requirements of the whole fund industry, there are relatively few professional management talents who have knowledge of financial securities, are proficient in asset management and are good at portfolio management, and the investment analysis, asset management level and operational efficiency of funds need to be improved.
