The largest position increases, new positions, decreases, and confirmed exits this cycle. Percent-change lists below require at least a $1M prior-quarter position, so a fund going from a handful of shares to a few thousand does not crowd out real, sized moves.
A small, non-exhaustive list of well-known funds and passive index giants we checked for by name, not a comprehensive classification of every institution on record.
These alone represent about +31% of total institutional value on record, a rough floor for index-driven (not conviction-driven) ownership.
"Since prior quarter" return uses each holder's prior-quarter value divided by prior-quarter shares as a rough implied entry price, not their real cost basis, which is not disclosed in 13F filings.
