Subject: Re: brkb big block on the open,
In recent history they did not pounce when things were looking bad.
I bought Berkshire at book value. Berkshire didn’t.

You mean first part of 2020 during the pandemic dip? That's the last time Berkshire traded at book.
Berkshire did repurchase shares at known book in May 2020.

They were thinking something else in April that year--possibly a deal being thought about?--but bought heavily every other month of the year.
