Subject: How high will this thing go?
Every day, BRK-B marches up.
Market up? BRK up.
Market down? BRK up.

Every day, up 4-6 points.

Latest P/B is 1.6. IIRC, BRK's P/B generally swings between 1.35 and 1.55 and its well beyond that now.

How high is it going to go? And how fast will the fall be, when it stumbles? 'course the other question is, Who is doing all this buying?

I now look back and regret selling my DITM calls when P/B hit 1.5 with BRKB at 383, but who knew.
