Some people buy funds, they all listen to others, make money, buy them themselves, and then leave them alone. Then when they remember, the fund may lose money to the principal.
In fact, when buying a fund, the same fund may make money or lose money. For example, A investment fund will be redeemed after making money, and A will tell B to make money. When B sees A's fund income, he will think that he wants to make money, so he knows nothing. I don't care if I buy it, thinking that the fund will make money after a while.
Then after a period of time, B will find that there is less money in the fund and will lose money to the principal. This is because when A buys the fund, the fund is at a low level, and then after the fund continues to rise to a certain high level, A redeems the fund to make money.
However, B heard that A made money and bought it. At that time, it was just right to buy at a high fund level. After the fund continued to fall, the foundation suffered losses. This tells us that when buying funds, don't blindly follow the trend, and you must know something before investing in funds, otherwise it is easy to suffer.
