Many holders are saving customers who are new to the fund market. They lack a certain amount of securities market investment experience and have not recognized or used funds as an important tool for achieving their long-term financial goals. Relevant data shows that most investors hold funds for no more than half a year. Such a frequent trading situation indicates that fund investors are not yet rational. Fund investment is a long-term investment and financial management activity, and fund holders should establish a long-term investment concept. Otherwise, quick in-and-out not only wastes resources but may also affect the investment operation of the fund, further exacerbating the fluctuation of the net asset value of the fund.
