Answer: B For the evaluation of fund performance, it is not enough to simply understand the rate of return achieved by investment products. Investors and fund companies also need to know how the fund manager performs relative to the market and how it performs relative to other fund managers.

Only through complete investment performance evaluation can investors have enough information to understand their investment status.

Investors can decide whether to continue using existing investment managers; fund management companies can decide whether a fund manager can manage more funds, can allocate more resources or needs to be replaced.

Funds with different investment objectives and scopes may have different investment strategies and performance comparison benchmarks, and their performance is not comparable.
