Refers to the suspension of redemption or redemption of investors' shares by funds or trusts. According to the inquiry of the financial sector, stopping redemption means that the fund or trust suspends redemption or redeems the investor's share, usually because the fund or trust faces liquidity pressure and cannot realize assets immediately to meet the investor's redemption request. This is because the assets invested by funds or trusts have fallen in value or liquidity problems, or the overall market situation has been bad.
