Not that I can see, especially since you are doing this all in the same calendar year. The one quirky thing would be if you didn’t lose the shares by the end of the year but did harvest some premiums on the calls. Then you would be paying gains on the collected premiums this year without any loss from the shares being sold to offset it. However, you’d eliminate this problem by making sure you sold the shares outright before the end of the year if they haven’t already been called away.
Curious to hear if you or others might be thinking any differently.
