<<I have sold BRK when I thought the stock was "over valued" and had BRK stock called away on covered calls I have written. I'm still smarting from the errors and promised never to repeat them.>>

When come close to the expiration day and you think the stock is not overvalued, or in a upward trend, you could buy back the calls. I did that a few months ago when the brk.b is about $460, lost $1000-$2000 per call, now I'm selling the calls again.
