Early Assignment of Covered Call Position in DICK'S Sporting Goods Inc.

I was notified by Schwab early this morning that the one DICK'S Sporting Goods Inc. December 20th, 2024 Call option was exercised early yesterday.  Because DICK'S stock price increased from $211.26 when this position was established to $218.86 at yesterday's market close, the original $2.84 time value in the Call when the position was established had declined on yesterday's market close to $0.84.  So, with 7 days remaining until the December 20th options expiration date, the owner of these Calls exercised their option to buy the 100 shares at the $202.50 strike price in order to receive today's $1.10 per share ex-dividend. 

I was surprised that the owner of the Call exercised their option in this instance since they decided to immediately forego $.84 time value profit potential (which I am pleased to have received as an immediate profit addition to my return-on-investment result for this position).  I am also pleased with the +45.6% annualized-return-on-investment (aroi) result achieved today by early assignment since it exceeds the maximum +38.6% aroi that might have been achieved if this position instead remained in-the-money and would therefore be assigned on its December 20th, 2024 options expiration date.   

The post when this DICK'S Sporting Goods Inc. Covered Call position was originally established is here.  As detailed below, the return-on-investment result for this Covered Calls position was +1.2% absolute return in 10 days (equivalent to a +45.6% annualized return-on-investment).
