Top institutional buyers and sellers of an exact stock or ETF listing — biggest absolute share additions and reductions versus the previous 13F report date, including new and sold-out positions. Movement is like-for-like: only filers with an observed 13F in both quarters rank, so a fund that has not filed yet, a first filer or a fund that stopped filing under its CIK is never read as a trade, and note names the largest filers left out. A filer that continues under one new CIK is compared through it (continuesFrom); one split across several new CIKs is left out. Movement needs the immediately preceding quarter on record; otherwise note says the comparison is unavailable. Share counts are restated onto today's split basis.

What happened to a requested ticker that no longer trades. "delisted": the company has no current US listing, so the answer is its history. "renamed": the company now trades as successorTicker, its current US presentation ticker (possibly another share class). A listed series (short volume, short interest, off-exchange volume, fails-to-deliver, congressional trades) is the retired ticker's own; a company-level read is the company's data.

Buyers and sellers are compared like-for-like: only filers with an observed 13F in both quarters rank, so a late filer, a first filer or a fund that stopped filing under its CIK is never read as a trade. A filer that continues under one new CIK is compared through it (continuesFrom); one split across several new CIKs is left out.
