No, the fund chasing up and down refers to an operation mode of buying at a high level and selling at a low level, which has a high probability of loss and is not a good time for investors to trade. The fund mainly earns the bid-ask price difference, and only by buying at a low price and selling at a high price can it gain income, so selling at a high price is a better operation mode of the fund.

However, the high investment and low investment of funds require investors to have a certain level of investment, and it is difficult to grasp the timing of trading, which requires a higher level of investment for investors. High investment and low investment are suitable for funds with large fluctuations.
