Selling is a read, too. We rank all 10,000+ funds that must disclose their trades by how their disclosed buys performed, follow only the specialists, and check whether they're still building BRK-B — or already out. Late and crowded is when holders historically got hurt.

Not held
None of the 500 graded funds holds BRK.B right now. That's not a verdict on the company — the specialists we grade simply aren't in it. We'll tell you if that changes.
Watch it — free — we'll email you the day institutional evidence appears.
