| Factors Affecting Performance [Text Block] | How Did the Fund Perform last year and what affected its performance? During the reporting period, the Fund generated a positive total return of 23.01%. This compares to the 33.60% total return for the S&P 500 Index for the same period. Based on our core key themes, we continue to attempt to position the strategy with strong and consistent advantages versus the benchmark and relative to the overall market. Portfolio positions have greater exposure to Mainland China, as we have a larger share of A-shares and H-shares. What Factors Influenced Performance? As interest rates remained high throughout the period, Chinese equities underperformed for most of the year. Furthermore, our A-share and H-share positions didn’t catch as much of the initial western capital rotation after the Chinese stimulus package was announced late September versus their American Depositary Receipt peers. The current market environment will remain uncertain as the market awaits clarity in policies from a new incoming administration. In general, we believe this administration will have more flexibility to constructively collaborate with China vs. opposing it on ideological grounds. | |
