The fund bought is not suitable for covering the position when it goes up. The higher the cost, the greater the risk that investors bear and the greater the probability of future losses. Funds generally cover their positions when they fall, which will reduce the cost for investors. The lower the cost, the less risk investors take and the greater the probability of future profit.

Investors can decide whether to add positions after the market. Looking at the net value of the fund at the end of the day, they can know the ups and downs of the fund that day. They will increase their positions when the fund falls, and they will not increase their positions when the fund rises.
