If the monthly 600 yuan is not a number you don't care about, it is still quite risky to use the money after three years, because none of us can guarantee that today is a big bull market after three years.
So I suggest that you choose one or two stocks or index funds for fixed investment (monthly 400 yuan), and then choose bond funds for fixed investment (monthly 200 yuan). In this way, even if it is a bear market three years later, you can take out your savings and invest in bond funds, while index or stock funds will continue to invest until they return to their original profits.
As for the choice of funds, we should choose the funds of fund companies with stable personnel, strong investment and research ability and complete product lines. The three funds mentioned in your question are all good, but I am more optimistic about Huaxia 300, because index funds follow and copy the index, which is a passive investment, less interfered by human factors, and will not suffer losses due to misjudgment of the economic situation and other reasons, which can better prevent the moral hazard of employees of non-performing funds, such as the well-known mouse warehouse.
If you want to invest in bond funds, you should choose a bond fund with strong strength, and you can buy a 20% share, so the income will be slightly better. I recommend Huaxia Hope Bond. Of course, there are many good bond funds, and you can also look for them on the fund website.
In addition, it is not recommended that you choose a fund with back-end fees, because you only make a fixed investment for three years, and most funds can't reach the subscription fee of 0 within the three-year holding period. Many fund companies stipulate that holding for five years is zero. Moreover, the subscription fee of the fixed investment fund is calculated in batches. At the time of redemption, your first fixed investment in 200 yuan has been completed for three years, and the subscription fee will be very low. The fund you invested in the last year will charge you a high subscription fee of 1.8%-2% due to its holding period of less than one year!
Answer your supplementary question:
If you insist on investing in index funds, of course, we think you are aware of the risks, because as I said above, index funds are risky, and you can choose bond funds to match them, but you gave up, so we put the risk in the second place and said income.
Fixed investment in two index funds has the advantage of fixed investment in two, so you need to choose different indexes and track different targets. The trends of different indexes are also different. You can observe that when the SSE 50 rises, the small and medium-sized board index performs generally, and when the SME index rises, the SSE 50 does not perform well. So if you want to invest in two funds, you must choose different indexes. There are many index funds now, and there is a lot of choice, including connecting ETFs.
Of course, I still suggest that you invest in a fund, which is more convenient to operate and manage. When choosing an index, choose an index with strong industry representation and wide coverage.
The purpose of investing in index funds is to obtain the average return of the market, not the excess return. If you want to get excess returns, you must buy active funds. Therefore, the standard for choosing index funds is to track whether the index is accurate!
Then how can we track it accurately?
First of all, the scale cannot be changed greatly, and fund managers have to be forced to sell or buy stocks to keep their positions. And what kind of fund size will not change dramatically? The scale is large, the bigger the better, and the buying point or selling point does not affect the overall position.
Secondly, the cost should be low. The subscription fees of the major Shanghai and Shenzhen 300 index funds in the market are 1.2% or 1.5%, so we naturally choose 1.2%. The redemption fee is generally 0.5%, and some are free after two years, while Huaxia Shen Hu is free after 300 years; Moreover, the management fee and custody fee of Huaxia CSI 300 are only 0.6% per year, which is also very beneficial for long-term income.
So I suggest you only invest in Huaxia 300.
