I invest in 200 yuan's fund every month in the postal service, and the customer service of the postal service chose 003003 fund for me. What is the income of this fund, suitable for long-term investment? Not suitable. This fund basically does not fluctuate, nor can it play the role of obtaining excess returns. The so-called fixed investment is to spread risks, so you must choose a fund with fluctuations, such as stock funds or index ETF funds, otherwise the function of fixed investment will not be reflected at all. It is suggested to choose stock funds or index funds. Bank customer service generally does not have professional fund knowledge. Instead of believing those people's nonsense, it is better to ask Baidu.
