This tracker follows Duquesne Family Office LLC’s Form 13F disclosures—not Stanley Druckenmiller’s personal brokerage account. 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.
