Common questions
What are Harbor Advisory’s 13F holdings worth?
$374 million across 82 positions for the quarter ended 30 June 2026.
What is Harbor Advisory’s largest 13F holding?
VANGUARD INDEX FDS (S&P 500 ETF SHS) was the largest position at $20.4 million, or 5.5% of reported 13F value, as of 30 June 2026.
How concentrated is Harbor Advisory’s 13F portfolio?
The ten largest positions accounted for 42.5% of reported value and the twenty-five largest for 76.4%, across 82 positions as of 30 June 2026.
Does Form 13F show everything Harbor Advisory 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 Harbor Advisory 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.
