This tracker follows Gotham Asset Management, LLC’s Form 13F disclosures—not Joel Greenblatt’s personal brokerage account. The filing is firm-level rather than a personal stock list. Form 13F reports quarter-end U.S.-listed positions and certain options, but it does not reveal exact trade dates, execution prices, short positions or the purpose of an option position.
