It takes 30,000 yuan to buy a grade B fund, more than 40 million yuan to buy a currency fund, and 15 million yuan to buy a bond fund.

1. If you buy a currency fund, based on the latest income of 10,000 units of Yu'e Bao, it is 0.6867 yuan; that is, if you buy 10,000 yuan, you can get an income of about 0.7 yuan a day, and you can earn 3,000 yuan a day. How much do you need to buy? 3000/0.7=42.857 million yuan. To round up the number, you probably need to buy a monetary fund worth 42.85 million yuan;

2. If you buy a bond fund, calculate it based on the annualized return of 8%, which is converted into an average daily return. The rate of return is about 20,000 yuan. Applying the above formula, 3000/2=15 million yuan;

3. If you buy a graded B fund, which is the fund with the highest leverage, highest risk and highest return, come every day The daily limit is 10%, and you only need about 30,000 yuan. 30,000 yuan*10%=3,000 yuan. Of course, the market may not rise every day, and Grade B may not necessarily rise every day.

If you encounter a decline, the leverage will also be enlarged, and you will also suffer heavy losses. The lower the risk (such as currency funds), the lower the return, but it is very stable; the higher the risk of the fund (such as graded funds), the higher the return, but it is extremely unstable and is very likely to suffer a big loss.
