The heavier the fund position, the greater the impact of the trend of the underlying asset on the trend of the fund. On the contrary, the lighter the fund position, the smaller the impact of the trend of the underlying asset on the trend of the fund.

Therefore, investors can buy and sell funds based on fund positions, that is, when the underlying asset with a heavier position rises, they buy the fund, and when the underlying asset with a heavier position falls, they sell the fund.

It should be noted that fund positions are not announced until 15 trading days from the end of each quarter, which has a certain lag.
