Fund clearance refers to the act of selling all the funds held and no longer holding the funds. Fund clearance refers to the behavior of holding some funds without selling all the funds held.

When the market is relatively poor, investors had better clear their positions. If the market is relatively good, then investors can sell some positions without clearing their positions, or they can keep some positions to prevent them from being empty. If the fund rises in the future, you can get higher returns by leaving some positions. If the fund subsequently falls and the position is not heavy, it can be sold in time.
