The 10 13F filers with the most shares as of Jun 30, 2026, whatever their type (index firms usually come first). “Change”: shares added or cut versus the previous quarter, split-adjusted; “no data” = there is no comparable portfolio for the previous quarter (no filing, or a filing with its holdings under confidential treatment). “% of the company” only where shares outstanding are up to date. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. With a free account: the top 25, the largest buyers and the largest sellers.

Shares reported by the 39 13F filers as of Jun 30, 2026, divided by the shares outstanding on the cover of the company's latest report (May 12, 2026). It is not all institutional ownership: only managers above $100M file a 13F, and it excludes short positions. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. We only publish it where the figure is credible: not for ADRs, companies with more than one share class or stale shares-outstanding data.

Fundamentals

Balance sheet only, for now. YCY has not yet filed its first annual report (10-K) with the SEC, so there are no 12-month figures (revenue, margins, earnings and cash flow). We show the balance sheet from its latest filing; once the 12-month figures are available, this section fills in automatically.
