The new fund publishes its net value once a week (usually updated after 9 pm on Friday). Investors can check the net value to see if the fund has any income. When the net value of the fund is greater than 1, the investor gains, and when the net value of the fund is less than 1, the investor loses.

During the opening of new funds, the fund manager will open positions on fund assets according to market conditions, and generate income after opening positions. If the market is poor and the fund manager does not open a position, then there will be no income.
