Early Closeout of Covered Calls Position in Halliburton Company

Last Thursday (July 6th, 2023), a Covered Calls position was established in Halliburton Company (ticker HAL) at the $31.00 strike price and for the July 21st, 2023 options expiration date. The stock price has increased from $32.66 when purchased to $36.51 this morning.  I have a "Rule-of-Thumb for Early Close Out" table (shown below), and this Halliburton Covered Calls position exceeded the minimum annualized-return-on-investment (aroi) threshold for closing out a position early.  This position has been held for 5 days now and there were 16 days total duration until the 7/21/2023 options expiration date which corresponds to category #2 in the rules table below.  The category #2 decision criteria is that the aroi if closed early be at least 80% higher than the aroi if the position was instead assigned on the original options expiration date. The aroi if assigned on the 7/21 expiration date would be 39.9% and a minimum threshold of an 80% increase above 39.9% is 71.8%.  As detailed below, this Covered Calls position was closed out early since the +97.4% aroi achieved by this early closeout exceeded the 71.8% minimum threshold in this instance.
