Among the 93 comparable managers: 11 buyers (opened or added shares) and 15 sellers (trimmed or exited), at least, among listed positions. Their net change in shares is not known from listed positions, because at least one of them lists it in only one of the two quarters.

Managers listing MDB in Q1 2024

Share of 13F value is the position’s reported value over everything the manager reported that quarter. The share change is against Q4 2023, and only where both filings list the position. A rise in value with no rise in shares is the price, not buying.

Every quarter on file. A quarter-end value moves with the price as well as with the shares held; buyers and sellers count comparable managers, by shares.

How much of the picture this is

A 13F is a manager’s long US-listed equity book at a quarter end, filed up to 45 days later. It shows no shorts, cash, bonds or performance, and it is never today’s portfolio. Large books are listed to their largest positions, so a manager missing from this table may still hold a small position below that line. These are 95 tracked managers, not the institutional market.
