The best way is to make a long-term fixed investment, and make a fixed investment every week. There is little difference between a few days a week. Because it is impossible to predict whether the future will rise or fall, and there is generally little difference between the first few days and the next few days.

After the fixed investment, no matter how the market fluctuates, they will buy a fixed amount of funds with different net worth every month, automatically forming an investment mode of lightening positions on rallies and adding positions on dips, so that the average cost is at the middle level of the market.

The fluctuation range of the whole year will be greater, and the risk of direct one-time investment will be greater. However, if you choose to invest regularly and stick to it, it will smooth the investment cost in the long run.

Matters needing attention in purchasing funds

1. To buy a fund, you must first open a fund account, which can be opened in a bank or a fund company.

2. According to your own risk tolerance, choose a fund suitable for your own situation to invest. When buying a fund online, investors are generally assessed for risk, so it is necessary to assess whether investors are suitable to buy the fund.

3. Know what kind of fund you are buying, whether it is a closed-end fund or not. At the same time, we should know that the income of the fund is related to the net growth rate, which can be used as a data reference when purchasing.
