Generally speaking, the rise or fall of the fund in the past has little effect on the rise behind the fund, but it will have certain reference function. It is an investment strategy for funds to buy down instead of buying up. Generally speaking, the fund buys when the trend falls, and the fund does not buy when it rises.
Because the buying cost will be lower when the fund falls than when it rises, investors can get more shares when the fund falls, reduce the cost of holding positions and spread risks, so the lower the cost of holding positions, the better. The lower the cost, the smaller the risk that investors take, and the higher the probability of earning in the future.
It is not a good idea for funds to buy down and not buy up. It's not that any fund can do it. Some funds have been performing poorly, often falling more and rising less. Some investors may think that they have fallen low enough to buy.
Then it will be locked up. The fund is like a bottomless black hole. If it falls frequently, it will cause losses. Therefore, whether the fund buys up or not depends on the fund. It should be considered from many aspects in combination with reality.
Investors should pay attention to the fact that the transactions during the fund trading hours are calculated according to the net value at the closing time, that is, the fund has only one trading price every day, and investors can decide whether to buy at the closing time of the day, buy when the fund falls, and do not buy when the fund rises.
