SEC Form N-PORT Tracker

🎯 Which funds hold a given stock? (reverse-ownership lookup)

The capability that sets this apart: give it a ticker, get back every mutual fund holding that security across recent SEC N-PORT filings.

{ "mode": "by_issuer", "issuer": "AAPL", "daysBack": 45 }

Matching is identifier-first — exact ticker, then exact CUSIP/ISIN — with an exact company-name fallback. It does not substring-match, so a search for National Beverage never returns Federal National Mortgage or Marriott International, and Apple Inc. never returns Apple Hospitality REIT or Applebee's.

Three modes

mode	question
by_issuer	which funds hold this security? (reverse ownership)
by_cik	what does this specific fund hold? (full portfolio)
recent_filings	what got filed recently?

🔀 Two N-PORT actors — which one do you want?

Both read the same public SEC data (N-PORT-P filings on EDGAR). They differ by the question you're asking:

You want to…	Use
Look something up — a named fund's portfolio, or which funds hold a stock.	This actor (Fund Portfolio & Security Ownership Lookup)
Watch new filings — scan recent N-PORT filings by keyword + date, no specific target yet.	SEC Fund Holdings Monitor

Targeted lookup → this one. Discovery/monitoring → the Monitor.
