The trend of the floor fund is not only influenced by the theme of the fund, but also by the trading volume in the market, that is, when the selling order in the market is greater than the buying order, the fund price will fall, and conversely, when the buying order in the market is greater than the selling order, the fund price will rise. Therefore, for the floor fund, many people selling will increase the empty strength of the market, leading to the decline of the fund.

For OTC funds, the trend of fund net value is affected by the trend of fund target, and the redemption of funds by investors has little effect on fund net value. However, if the fund is profitable on that day and the fund is redeemed at a huge amount, the fund share will be greatly reduced, resulting in a sharp increase in the fund's net value.

Among them, the fund manager can postpone the remaining redemption applications or accept full redemption on the premise that the proportion of redemption accepted on the same day is not less than 10% of the total fund share of the previous day, that is, when the fund manager thinks that he has the ability to pay the investor's full redemption application, the normal redemption procedure will be implemented.
