Class B share refers to the part with higher expected risks and returns and lower priority among the two types of shares divided into basic shares of graded funds, which is called Class B share here. Secondly, share B is the leveraged party in the graded fund. Graded funds generally divide their shares into A and B. B pays interest to A and invests with A's funds, but the overall investment profit and loss after paying interest is borne by B's share.

Precautions for graded funds:

The index tracked by graded funds indicates its overall performance. At present, the targets tracked by stock grading funds involve index, industry and theme. Investors need to analyze the market and choose the graded fund varieties corresponding to the optimistic target.

The discount rate has a significant impact on the prices of graded funds A and B. Due to the mature arbitrage mechanism in the market, the discount rate is usually kept at a low level. If the premium rate is too high, the investment grade B should be considered after the premium returns to normal.
