Not necessarily, investors can choose to buy in one lump sum or in batches. When the market is good, they can buy it once, and when the market is normal, they can buy it in batches. The advantage of buying in batches is that you can share the cost when the fund falls. The lower the cost, the smaller the risk, and the greater the probability of obtaining benefits in the future.

Fund buying skills: If the fund rises that day, you can temporarily stop buying, and if the fund falls that day, you can buy (the buying cost of the fund falling is lower). The rise and fall of the fund on the day depends on the fund's net value estimate, which is the trend of the fund on the day.
