1. annualized rate of return is to convert the rate of return in a certain period (which can be less than 1 year or more than 1 year) into the rate of return of 1 year. For example, the monthly rate of return 1%, and the annualized rate of return is 1%* 12= 12%. If the three-year total yield is 45%, the annualized rate of return is 45%/3= 15%. (excluding compound interest)

2. Discount insurance rate. The formula 1 is available on the floor, which is just like clothes discount. 60 yuan sells clothes at 100 yuan to you, which means a discount rate of 40%. Selling clothes at 120 yuan means a premium of 20%.

3. The guarantee is generally based on discount. Generally speaking, it is expressed as "discount rate 20.82%" or "premium 10%", and the discount rate is rarely mentioned. If discount premium rate is used, a positive number means premium and a negative number means discount.

4. The annualized rate of return in the last three years is 45.35%, which means that the fund can get an average annual income of 45.35% in the last three years, and the total income in the three years is (1+45.35%)*3.

If you want to compare with open-end fund, it depends on which one you compare with.
