Early Assignment of Covered Calls Position in Exxon Mobil Corporation

Early this morning I was notified by my broker's email that the two Exxon Mobil Corporation (ticker XOM) November 24th, 2023 $101.00 Call options were exercised yesterday.  Exxon Mobil stock has increased from its purchase price of $102.97 last Wednesday when this Covered Calls position was established to $104.84 at the market close yesterday.  The original $.82 time value in the Calls when the position was established had declined on yesterday's market close to $0.01, so I was not surprised that the owner of these Exxon Calls exercised their option to buy the 200 shares at the $101.00 strike price in order to receive today's $.95 per share ex-dividend.  I am pleased for this early assignment despite losing the opportunity to capture the $.95 ex-dividend since the +49.4% annualized-return-on-investment (aroi) achieved by early assignment is greater than the +40.2% aroi that would instead have been achieved if this position was instead assigned on its November 24th options expiration date.   

The post when this Exxon Mobil Covered Calls position was originally established is here.  As detailed below, the return-on-investment result for this Exxon Mobil Covered Calls position was +0.8% absolute return in 6 days (equivalent to a +49.4% annualized return-on-investment).
