Common questions
What are October Effect’s 13F holdings worth?
$106 million across 64 positions for the quarter ended 30 June 2026.
What is October Effect’s largest 13F holding?
WESTERN DIGITAL CORP (COM) was the largest position at $8.04 million, or 7.6% of reported 13F value, as of 30 June 2026.
How concentrated is October Effect’s 13F portfolio?
The ten largest positions accounted for 45.9% of reported value and the twenty-five largest for 78.0%, across 64 positions as of 30 June 2026.
Does Form 13F show everything October Effect 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 October Effect 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.
