Investing in overseas funds is the same as investing in other financial products. Investors need to choose the product that suits them best. Investors should first choose one or more fund categories according to their own income and risk preference, combined with investment philosophy, investment period and liquidity requirements. After selecting the fund category, investors can compare similar funds with different historical characteristics under the same benchmark, including quantitative standards such as scale, excess return, tracking error, absolute return, volatility, correlation rate, average market value, style, heavy industry and individual stocks, target quality and total cost, and select a candidate list. Of course, investors can also refer to the rating agencies' ratings of funds and other reference opinions. Finally, investors can analyze the advantages and disadvantages of each product on a qualitative level, and finally choose their favorite funds. These qualitative considerations include the reputation of the fund company, team experience, risk control mechanism and overall service to investors.
