Use your mobile phone to find out which fund has the highest cumulative net worth. You can download a mobile app of Tian Tian Fund Network or Cool Fund Network, especially Tian Tian Fund Network. The above funds are very comprehensive, including the ranking of fund net value and accumulated net value. It is very convenient to distinguish different types of funds for ranking. In addition, buying a fund mainly depends on past performance and the fund manager's stock selection ability. If you choose from the accumulated net value of the fund, it is of little significance, because the time when the fund is established is different, and the stock market opportunities encountered when it is established are also different. Therefore, it is of little value to distinguish the advantages and disadvantages of funds simply by the accumulated net value.
