Common questions
What are Two Sigma Investments’ 13F holdings worth?
$138,117,670,065 across 5,017 positions for the quarter ended 30 June 2026.
What is Two Sigma Investments’ largest 13F holding?
WESTERN DIGITAL CORP (NOTE 3.000%11/1) was the largest position at $1,497,883,248, or 1.1% of reported 13F value, as of 30 June 2026.
How concentrated is Two Sigma Investments’ 13F portfolio?
The ten largest positions accounted for 8.3% of reported value and the twenty-five largest for 16.7%, across 5,017 positions as of 30 June 2026.
Does Form 13F show everything Two Sigma Investments 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 Two Sigma Investments 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.
