After buying a fund, the principal will not be fully deducted for a long time. Generally speaking, only when the net value of the fund is 0 can the fund lose money completely after the loss. In fact, the net value of the fund will not be lower than 0. When the net value of the fund is lower than that of 0.3 yuan, it will reach the liquidation line, and some funds will be returned after liquidation. In addition, general fund companies will not let it fall. When the fund falls seriously, they may take the form of discount to restore the net value of the fund to more than one yuan at this time.

It is worth noting that the long-term investment of the fund does not mean staying here for a long time. If investors choose high-quality funds, there may be unexpected surprises in the long run, but if they choose poor funds, they may lose a lot in the long run. If you are not a value investor, you can do this after the stock falls, and you don't have to hold it all the time:

1, covering positions. When the stock price falls, investors can make up their positions when the stock price has obvious support, which can reduce costs.

2. Band operation. That is, when the stock price rises, sell a part, and then sell it when the stock price falls. By repeatedly throwing high and sucking low, the cost is reduced.

Step 3 cut the meat. If the company's fundamentals are not good, cut the meat in time to reduce losses.
