Note(s): This table compares the risk-adjusted return performance of four Chinese ETFs (CQQQ, FXI, GXC, MCHI) using Calmar, Martin, Omega, and Sharpe ratios across two periods: pre-COVID-19 (9/09/2014 to 1/02/2020) and post-COVID-19 (1/02/2020 to 6/09/2024). Based on all four measures, the Chinese ETFs were outperformed by VT in both periods. While CQQQ came closest to VT in several ratios before COVID-19, post-pandemic results showed a marked decline across all Chinese ETFs, especially in the Sharpe and Martin ratios, where some exhibited negative returns

Source(s): All four measures were calculated in the online lab developed by Shevchenko (2024) on 10 September 2024. Each daily measure utilizes a one-year lookback period, averaged over each period, and the risk-free interest rate is based on the average yield of 90-day Treasury bills
