Early Assignment of Covered Calls Position in Citigroup Inc.

My five Citigroup Inc. November 8th, 2024 Call options were exercised on Friday 11/01/2024.  Because Citi's stock price increased from $62.67 when this position was established to $63.71 at yesterday's market close, the original $.53 time value in the Calls when the position was established had declined on yesterday's market close to $0.00, so (with seven days remaining until the November 8th options expiration date), the owner of these Calls exercised their option to buy the 500 shares at the $60.00 strike price in order to receive Monday's $.56 per share ex-dividend. 

The post when this Citigroup Covered Calls position was originally established is here.  As detailed below, the return-on-investment result for this Citigroup Covered Calls position was +0.9% absolute return-on-investment in 8 days (equivalent to a +40.1% annualized return-on-investment).
