The Fund is a fund among funds, and strives to keep the daily growth rate of fund net value equal to the benchmark growth rate of performance. Theoretically, it has the risk-return characteristics similar to the performance comparison benchmark.

Therefore, the Fund is a fund with high expected returns and expected risks. The Fund may invest in overseas securities investment funds. In addition to the market fluctuation risk similar to that of domestic securities investment funds, the Fund also faces special investment risks such as exchange rate risk.
