Quarterly 13F filings
Citadel Advisors reports its U.S. stock holdings to the SEC every quarter, within 45 days of the quarter's end.
What changed, not just what's held
We compare each filing with the previous one, so the alert opens with new positions, big adds, and exits instead of the full list of holdings.
Straight from the SEC
No middleman data feed. We check EDGAR, the SEC's public filing system, every day and link each alert to the original filing.
