The advantage of the fund's fixed investment is that when the market is unfavorable, the fixed investment can dilute our capital cost, and when we go through a basically formed "smile curve", we will certainly get considerable investment income. However, many investors are entangled in the cycle of fixed investment, so is it better to make a fixed investment in the fund?

is it better to make a weekly investment or a fixed investment?

Monthly fixed investment and weekly fixed investment have their own adaptations:

1 If the market price at the beginning of fixed investment happens to be at the top of the stage, the probability of a bigger gap between stock prices in different periods is higher with a longer fixed investment interval, so monthly fixed investment is more conducive to diluting the cost of opening positions than weekly fixed investment. When the "smile curve" is basically formed, the probability of monthly fixed investment is higher than that of weekly fixed investment.

2 if the market price at the beginning of fixed investment happens to be at the bottom of the stage, the average cost of opening a warehouse for weekly fixed investment is lower than that for monthly fixed investment, so weekly fixed investment can better seize the income.
