Established Covered Calls Position in iShares China Large-Cap ETF

A second Covered Calls position was established in iShares China Large-Cap ETF (FXI). The first position expires today and is likely to be called away since it is in-the-money and near the closing time of today's trading. I want to maintain an ongoing Covered Calls position in iShares China Large-Cap ETF so this second position has a two-week duration and expires on the September 15th, 2023 monthly options expiration date.  This is consistent with my ongoing plan to establish approximately bi-weekly Covered Calls in FXI in upcoming weeks this year.  Finally, the fact that investing in China-based companies improves the diversification of the Covered Calls Advisor Portfolio appeals to me.  In short, it serves as a counterbalance to my normal home country bias.  

One thousand shares of iShares China Large-Cap ETF were purchased at $27.99 and ten Sept. 15th, 2023 Call options were sold at the $28.00 strike price at $.63 per share--a buy/write net debit transaction of $27.36 per share which provides a $.64 per share time value profit potential.  

As detailed below, a potential return-on-investment result is +2.3% absolute return (equivalent to +59.4% annualized return-on-investment for the next 14 days) if the iShares China Large-Cap ETF share price is in-the-money (i.e. above the $28.00 strike price) and therefore assigned on the September 15th, 2023 options expiration date.
