There are two ways to compare fund performance. One is global comparison, which ranks all funds or the same group of funds together. Second, compare the fund with a predetermined benchmark. This predetermined benchmark is the performance comparison benchmark of the Fund. This comparison method measures the fund performance by defining a suitable benchmark portfolio for the evaluated fund and comparing the difference between the fund return rate and the benchmark portfolio return rate. The benchmark portfolio is an investable and unmanaged portfolio with the same style as the fund. Performance comparison benchmark is an important criterion for investors to evaluate the performance of fund management companies.

Since 2002, the regulatory authorities have required open-end funds to publish performance benchmarks at the time of issuance, and funds with different risks and returns track different benchmarks, which is conducive to the stability of fund style and investors' reasonable evaluation of fund performance.
