What big funds hold.

Large investment managers must report their US stock holdings to the SEC every quarter (Form 13F). Pick one to see its biggest positions and what it bought or sold since the last report. The changes are calculated from the filings, not guessed.

Read this first. A 13F shows only long positions in US-listed securities as of the quarter's last day, and it is published up to 45 days later. It does not show short positions, cash, most bonds, or anything held abroad, and a fund may have changed since. It is a delayed, partial picture, not a recommendation to buy or sell anything.
