Institutional stock holdings for a fund manager, from its latest SEC Form 13F.
13F filings split the actual holdings into a separate "information table" XML document that the filing index does not point at directly; this locates it, parses every position, and rolls up lots reported separately (different share classes, put/call splits) into one row per issuer.
When to use: seeing what a fund or institution holds and how much, tracking "smart money" positioning, portfolio research.
When NOT to use: real-time positions (13F is filed up to 45 days after quarter end, so this is always historical), short positions (13F does not require disclosing shorts), or non-U.S. filers.
Args:
- ticker (string, required): the FILER's ticker (if it has one) or its SEC CIK, e.g. "1067983" for Berkshire Hathaway.
- limit (integer, optional, default 25): maximum holdings to return, largest by value first (1-200).
