Graded funds, also known as "structured funds", refer to the types of funds that show two-level (or multi-level) risk-return performance with a certain differentiated fund share by decomposing the fund income or net assets under a portfolio. Its main feature is to divide the fund products into two types of shares and give different income distribution respectively. The sum of the product of the net value and proportion of each sub-fund of the graded fund is equal to the net value of the parent fund.
If you don't want to take risks and pursue fixed income, you can buy Class A shares, similar to bonds.
If you want to pursue high returns, you can buy a class B share, which is several times that of the parent fund.
The simplest way to buy is to open a securities account in a securities company, and then place an order for trading anytime and anywhere through a computer, mobile phone or telephone.
