The securities market is a high-risk market, which is affected by the national economic situation, policy changes and the market's own laws. Under the background of the rapid development of China's securities investment fund market, the number and scale of funds have been expanding, and market risk has rapidly become the main risk facing China's securities investment fund market. In most frameworks, risk measurement is a function of portfolio returns in all possible ranges. Once the behavior of investors can be expressed numerically, it is actually possible to use different optimization methods to calculate the optimal asset allocation for a particular investor.
