A fund with a value of 1 yuan rose by 20%, and a fund with a value of 5 yuan rose by 30%. Even if the investment is the same, it is 1 1,000 yuan. Although 5 yuan bought a small amount of stocks, his income was higher than the former. I can always buy a fund when I can't get 2 yuan. There are many times in 3 yuan, 4 yuan and even 5 yuan. As long as I don't suspend sales, I will always increase them. Facts have also proved that it has a higher rate of return than other funds I bought, because I value its rate of return.
