Who owns the ASX
Ownership
Super funds, index funds, hedge funds, banks and the rest of the register: every substantial holding notice read from its PDF, the full holdings of the largest index ETFs and super fund options, and where a crowded register meets heavy short interest.
Ownership data is not available yet. It is collected once a day from ASX substantial holding notices, APRA, ASX's investment products report and the funds' own holdings files. Check back later today.
Sources and method
Substantial holdings are the voting power stated in each holder's latest ASX notice (Corporations Act s671B, Forms 603, 604 and 605), read from the notice PDF. A holding is shown until a later notice says it changed or ceased; the date is the notice's. Notices whose voting power cannot be read unambiguously (a scanned form, a figure only in an annexure) are withheld, never estimated.
Holders' interests can overlap: MUFG reports Morgan Stanley's and First Sentier's interests as its own. Sums count each interest once where the overlap is known (a group and its member count the larger figure; two notices disclosing the same voting power on the same date count once), and every holder is still listed. Other overlaps remain, so a sum is what the notices disclose, not a share of the company. Banks' and brokers' notices are mostly securities lending, often to short sellers.
Index ETF holdings are the funds' own holdings files; super fund holdings are each fund's portfolio holdings disclosure for one investment option (its default or balanced option), not the whole fund. Short interest is ASIC's daily short position report. Not financial advice.
