N2 - The equity fund is a mutual fund that invests principally in stocks, which can offer better returns and more adequate risk management. We propose a fund-stock network projection model to study the investment laws of the equity fund. This model allows us to calculate the importance of each stock, which can effectively quantify the relative investment strength of the equity fund in stocks. We studied the investment level, investment distribution and investment tendency of the equity fund based on the importance of stocks. The simulation results show that the investment level of the equity fund is better than the average investment level of the market. The investment distribution of the equity fund exhibits a near-power law distribution with fat tails. The equity fund is most biased towards investing in the finance industry, and adjusts the investment ratio of different industries according to the fluctuations of the stock market. Then an investment strategy is proposed based on the importance of stocks, which provides some references for investors.
