Early Assignment of Covered Calls Position in U.S. Bancorp

I was notified via email early this morning by my broker (Schwab) that the three U.S. Bancorp (ticker USB) June 27th, 2025 Call options were exercised yesterday.  USB's stock price increased from $42.96 when this position was established to $45.76 at yesterday's market close.  The original $.35 time value in the Calls when the position was established had declined on yesterday's market close to $0.00.  So, with fourteen days remaining until the July 11th, 2025 options expiration date, the owner of these Calls exercised their option to buy the 300 shares at the $42.00 strike price in order to receive Monday's $.50 per share ex-dividend.  Although I will not receive the ex-dividend, I am pleased with the +43.0% annualized-return-on-investment (aroi) result achieved since it slightly exceeds the maximum aroi that might have been achieved if this position instead remained in-the-money and would therefore be assigned on the July 11th options expiration date.   

The post when this U.S. Bancorp Covered Calls position was originally established is here.  

As detailed below, the return-on-investment result for this U.S. Bancorp Covered Calls position was +0.8% absolute return in 7 days (equivalent to a +43.0% annualized return-on-investment).
