Subject: Re: brkb, short calls the hard part.
This is 25-year-old common in a taxable account, getting called isn't an option...

Well, the response from a sensible advisor would be not to write calls against that position. : )

If you fear you are in danger of having your call exercised against a holding with a large gain, why can't you buy a new lot and tell your broker to deliver this new lot. If it doesn't get exercised sell it after the call expires.

After a couple of times, I decided that the risk and fear was not worth the small amount of money that I got from selling a call was not worth it.
