Fund companies usually announce the net value of funds after the end of each trading day. Investors can log on to official website, a fund company, or to third-party fund platforms (such as Ant Fund and Tian Tian Fund) to inquire about the rise and fall of fund net value, and check the real-time valuation of funds in the market. For exchange-listed funds, such as trading open-end funds (ETFs) and listed open-end funds (LOF), investors can check the real-time valuation of funds in the securities trading software. These data will be updated in real time during trading hours. Use disk reading software. Download watch software (such as Tong Daxin, Straight Flush, Oriental Fortune, etc.). ). In the quotation pages of these softwares, investors can search for fund codes or keywords to find and view the valuation of funds. In addition, investors can also learn about the changes in the fund's portfolio by paying attention to the fund's regular reports (such as quarterly reports and annual reports) and the information on changes in positions announced by fund companies.
