Hedge fund, long-only 13F filer

Citadel Advisors

Citadel Advisors is the multi-strategy investment firm Ken Griffin founded in 1990, running equities, fixed income and macro, credit, commodities and quantitative strategies. Its books are heavily hedged with options, which inflates the notional value a 13F discloses. It discloses US-listed long equity (and some options) positions each quarter on SEC Form 13F — bonds, cash, private businesses and non-US holdings are not in that filing.
