Fund decline 100%. No money?
Theoretically, if the fund falls by 100%, the principal will be lost, but in practice, this rarely happens because the foundation is graded. Generally, money funds and bond funds have little risk. They don't invest in the stock market, and their income is calculated on a daily basis, with little loss.
Equity funds, hybrid funds and index funds are relatively risky funds, some of which are invested in the stock market. Although the risk is relatively high, it is unlikely that they will fall by 100%, because some investors will stop their losses when the funds fall, and will not make them lose money. If they redeem a little, they won't lose 100%.
Will the fund net value fall to 0?
Generally speaking, the net value of the fund rarely falls to zero, because when the fund loses money to a certain extent, the fund will be liquidated. If the fund is liquidated, the fund will not continue to lose money and will distribute the remaining shares to investors.
If the fund loses money to the extent of liquidation, there will basically be no more left, so when buying a fund, you should learn to stop loss, that is, you should set a stop loss point. When the fund loses to this stop loss point, it is necessary to stop the loss in time to avoid the loss from expanding. When the fund returns to a certain extent, everyone needs to learn to take profit.
