Who owns ISNRU
Which tracked institutional funds hold ISNRU, how they are positioned, and who is buying versus exiting — from SEC Form 13F-HR filings. See ISNRU company fundamentals →
Ownership as of the 2026-Q2 13F filings (latest filed 2026-08-14). 13F is disclosed up to 45 days after quarter-end, so the most recent quarter fills in over the following weeks.
Conviction spread
ISNRU’s largest tracked holder by dollar value, ADAGE CAPITAL PARTNERS GP, L.L.C., sizes it at 0.0% of its own reported 13F book, while the median holder sizes it at 0.1% of theirs — a 0.1pp gap the other way — the median holder sizes ISNRU more heavily than its largest holder by dollar value does.
Book-share is each fund’s reported value in ISNRU divided by its whole reported 13F book, so it is comparable across funds of different sizes and is unaffected by stock splits. A higher share means a fund has committed more of its book to the name — a starting question about conviction, not a verdict or a signal to trade.
Institutional & insider positioning
Only one quarter (2026-Q2) of 13F history is available — a quarter-over-quarter accumulation delta needs two.
We do not publish a positioning read for a window we cannot measure honestly. A starting question, not a verdict.
Institutional holders
One row per tracked fund, most shares held first (every row is from one quarter; reported value breaks ties). “% of value” is the fund’s share of this security’s tracked institutional value — not of shares outstanding.

Reading this table
Funds hold the same stock for different reasons — an index fund “holds” almost everything, an active manager sizes a name to a mandate and a benchmark, and each fund entered at its own price and time. Because 13F is filed up to 45 days after quarter-end, every row is a backward-looking snapshot; a manager may have traded since. Share-class siblings (a company’s A and C shares) are rolled up to one line so a dual-class name is never double-counted. Compare like-for-like. A large holder is not an endorsement, and a fund exiting is not a warning — this is a starting question, not a verdict.
About 13F filings
A Form 13F is a quarterly disclosure that institutional investment managers with over $100 million in US-listed equities must file with the SEC. In plain English: it is a snapshot of the long stock positions a fund held at the end of a quarter. It covers long US-listed equities only — not short positions, options, cash, or private holdings — and the funds shown are the large sample we track, not the complete 13F universe.
