Funds are generally divided into: money funds, bond funds, mixed funds, stock funds, index funds, QDII funds and so on. Different funds represent different risks and returns. Generally speaking, money funds and bond funds with relatively low risks basically have very limited returns. It's hard to earn 1000 for a fund of 5000 for several years, let alone a year.
So, let's take the stock fund with relatively high risk as an example to explain it to you. Generally speaking, it is still possible for stock funds to increase by 20% a year when the market is good. Suppose an investor has 5000 yuan, and the expected increase of the fund is 20% in one year, then the money earned is: 5000*20%= 1000 yuan.
So buying a 5000 fund can earn 1000, just saying that it may take a long time, maybe one year, two years, three years and so on. And certainly not in a month or two. The above example means that the fund can earn 1000 yuan when the market is good and lose 1000 yuan when the market is bad.
