Stocks Quarterly Institutional Ownership
One row per ticker and quarter: how many 13F filers held it, how many shares they held in all, and what those shares were worth -- the aggregate of the position table.
Shape measured at the next refresh of dataset_cards/facts.json. Refreshed monthly.
Why It Matters
Half the institutional-ownership papers need no position at all, only the breadth: the number of holders of a name and how it changed, the institutional share once the shares held are divided by shares outstanding from the fundamentals, the names institutions were leaving. This table is that aggregate, computed from Stocks-Quarterly-InstitutionalHoldings with option positions excluded, share positions only, and one filing per filer and quarter (an amendment supersedes the original).
Dates. date is the quarter end the positions describe, not the filing date. The aggregate is only known 45 days later, when the last filer has reported, so a strategy must lag this table by at least that much. It is the opposite convention from the position table, where a row is dated when it became public.
