Common questions
What are Ursa Fund Management’s 13F holdings worth?
$1.28 billion across 38 positions for the quarter ended 30 June 2026.
What is Ursa Fund Management’s largest 13F holding?
MICROSOFT CORP (COM) was the largest position at $205 million, or 16.0% of reported 13F value, as of 30 June 2026.
How concentrated is Ursa Fund Management’s 13F portfolio?
The ten largest positions accounted for 86.8% of reported value and the twenty-five largest for 99.5%, across 38 positions as of 30 June 2026.
Does Form 13F show everything Ursa Fund 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 Ursa Fund 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.
