Off-exchange funds will not, and on-exchange funds may. OTC funds are redeemed from fund companies, so there is no need for other investors to take over, so there is no situation that they cannot be sold, and the fund companies will leave some cash to correspond to the daily redemption of investors, so they will not sell.
On-site fund transactions need to be taken over by other investors, so there is a situation that they cannot be sold, and the price of on-site funds is also limited. If the fund goes down, there is a high probability that it will not be sold.
