Who Holds JMUB

Last 8 quarters through Sep 30, 2026 (filing window open)

Each kind of 13F filer's share of the common shares 13F filers report. Holder type comes from regulatory records, never the filer's name; style, turnover and horizon are measured from each filer's own 13F book. The quarter selector does not change this card.

Jun 30, 2026, the newest closed quarter: 511 filers, like-for-like change +9.6%; actively managed books +9.9%; index-like books -10.5%.

Holder type Share Filers Change
Registered adviser 49.9% 370 +13.0%
Exempt adviser 0.0% 1 +5722.4%
Adviser 3.2% 3 +13.1%
Bank 15.7% 13 -2.1%
Broker-dealer 6.4% 1 +9.1%

Holding company 2.9% 5 -0.6%
Unknown 21.9% 117 +12.8%

The Sep 30, 2026 filing window is still open, so its bar shows only the filers that have filed so far.

How the mix is measured

Shares are 13F common shares restated to today's split basis; options and principal amounts are left out. The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none was. Actively managed books are those measured systematic-like, concentrated or diversified active.

Excluded 4 holders with no observed 2026-03-31 13F and 11 holders with no observed 2026-06-30 13F.

Estimated Holder Cost Basis

Quarter ended Jun 30, 2026, on that quarter's share basis

Estimated, never filed: each 13F buy is costed at its quarter's average traded price and each sale keeps the average cost, so this is what holders paid on average if they traded evenly through each quarter.
