At the time of initial offering and issuance, the net value of a single share is 1, and the fund manager is responsible for the investment.
If you do well, the net value of the fund will naturally start to rise, and it will double when it reaches 2.
The net value reached 0.5, indicating that the fund manager lost money in investment.
So this shows that any investment is risky, and so is the fund. See the risks clearly and treat them rationally.
