Common questions
What are Mason & Associates’ 13F holdings worth?
$619 million across 161 positions for the quarter ended 30 June 2026.
What is Mason & Associates’ largest 13F holding?
ISHARES TR (RUS 1000 ETF) was the largest position at $68 million, or 11.0% of reported 13F value, as of 30 June 2026.
How concentrated is Mason & Associates’ 13F portfolio?
The ten largest positions accounted for 48.0% of reported value and the twenty-five largest for 72.9%, across 161 positions as of 30 June 2026.
Does Form 13F show everything Mason & Associates 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 Mason & Associates 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.
