" I often think, given when I first started posting on Berk forums was getting close to 30 years ago, that my $500,000-$600,000 or so of Berk wasn't back then considered anything special on the forum. But today the 25 shares is heading to $18,500,000. So on the forums from the beginning the theme was buy when it was a bargain and sell some when it was over-valued."

I was trading brk options before the split so on some days I was the volume, they weren't very liquid, prior to the split lol. Selling puts has been a lay-up, selling calls has been a HUGE mistake. What you did was the correct strategy, period. Well done especially if you are an American. No doubt those who are, factually challenged, will PROUDLY share the brilliance of their brk call sales. If Buffett has NO IDEA what Mr. Market will pay for brkb, and if HE has no idea how to value brk relative to market demand, who here can? Stay healthy and enjoy the score.

Disclosure, we had a seat on the NYSE and the Philly option exchange for decades. When special people here aka, option experts, post on their option strategies, it makes my day!
