Broker B is a graded fund, and its listing was terminated on June 1 2002. At present, there is no graded fund in the market, which is complex, risky and unstable and has a certain leverage effect. There are some defects in this product. The leverage effect is weakened when the fund rises, and the leverage multiple of Grade B is increased when the fund falls.

Graded funds, also known as structured funds, are divided into parent funds, A funds and B funds, forming a variety of funds with multi-level risk-return performance and certain differentiated fund shares.
