The current market value of the fund's high-throwing and low-sucking formula = the accumulated fund share * the current fund net value. According to relevant information, the formula of high selling and low sucking of funds is current market value = accumulated fund share * current fund net value, and subscription amount = target market value-current market value. If the subscription amount is negative, it means that the fund will be redeemed. Selling high and sucking low refers to the behavior of investors selling stocks after the stock price rises for a period of time, and then buying at a low level when the stock price stops falling, which can reduce costs or increase profit margins.
