Common questions
What are Stembrook Asset Management’s 13F holdings worth?
$116 million across 51 positions for the quarter ended 30 June 2026.
What is Stembrook Asset Management’s largest 13F holding?
APPLE INC (COM) was the largest position at $40.4 million, or 34.9% of reported 13F value, as of 30 June 2026.
How concentrated is Stembrook Asset Management’s 13F portfolio?
The ten largest positions accounted for 83.6% of reported value and the twenty-five largest for 93.2%, across 51 positions as of 30 June 2026.
Does Form 13F show everything Stembrook 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 Stembrook 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.
