Common questions
What are Warberg Asset Management’s 13F holdings worth?
$551 million across 170 positions for the quarter ended 30 June 2026.
What is Warberg Asset Management’s largest 13F holding?
STATE STR SPDR S&P 500 ETF T (TR UNIT) was the largest position at $172 million, or 31.2% of reported 13F value, as of 30 June 2026.
How concentrated is Warberg Asset Management’s 13F portfolio?
The ten largest positions accounted for 68.8% of reported value and the twenty-five largest for 84.7%, across 170 positions as of 30 June 2026.
Does Form 13F show everything Warberg 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 Warberg 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.
