The most suitable fund for long-term fixed investment is Huaxia Return Fund, which has a stable trend, no ups and downs, less risk, moderate income and the most dividends. No matter how the stock index fluctuates, if such a fund invests for a long time, the probability of overall loss is very small. After the fixed investment, the dividend method will be changed to dividend reinvestment, so that you can get more fund shares for free when the fund pays dividends, which will be higher than the income from choosing dividends.
