Common questions
What are Rafferty Asset Management’s 13F holdings worth?
$43,915,729,091 across 1,133 positions for the quarter ended 30 June 2026.
What is Rafferty Asset Management’s largest 13F holding?
MICRON TECHNOLOGY INC (COM) was the largest position at $3,556,508,313, or 8.1% of reported 13F value, as of 30 June 2026.
How concentrated is Rafferty Asset Management’s 13F portfolio?

Does Form 13F show everything Rafferty Asset Management manages?
No. Form 13F covers only long positions in exchange-traded securities over which the manager has investment discretion, valued at quarter end. It excludes cash, most bonds, private funds, and any assets the firm does not have discretion over, so it is neither the firm's total assets nor any individual client's portfolio.
How often does Rafferty Asset Management file its 13F?
Every quarter. Managers file within 45 days of each quarter's end, so the figures are a snapshot that changes between filings. This page shows the quarter ended 30 June 2026.
Answered from this filing and the prior quarter's.
