What is Mainstream Capital Management’s largest 13F holding?

How concentrated is Mainstream Capital Management’s 13F portfolio?

Does Form 13F show everything Mainstream Capital 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 Mainstream Capital 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.
