I didn't say that I must learn to trade stocks before buying a fund. This statement is not absolute, but there may be a relationship between the two. When I learn to trade stocks, I will find it easier to make money when I come back as a fund, because the fund is generally a basket of stocks or a combination of some investment varieties. First, the fund reduces the risk nature of investment in terms of risk fluctuation, and then if I can trade stocks myself, it will be easier to identify and choose a fund with good performance.
