Value vs. prior quarter

Winslow Capital Management’s reported 13F holdings total $29.06B across 66 positions as of 30 June 2026. The ten largest make up 49.7% of it, and its value rose 13.3% from the prior quarter.

Form 13F lists long positions in exchange-traded securities over which the filer had investment discretion, valued at quarter end. It excludes cash, bonds held outside 13(f) securities, private funds, and assets the firm does not have discretion over, so the $29.06B reported here is not the firm's $28.66B in regulatory assets, and it does not represent any individual client's portfolio.

Common questions

What are Winslow Capital Management’s 13F holdings worth?

$29,059,630,524 across 66 positions for the quarter ended 30 June 2026.

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

NVIDIA Corp (COM) was the largest position at $3,121,479,033, or 10.7% of reported 13F value, as of 30 June 2026.

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

The ten largest positions accounted for 49.7% of reported value and the twenty-five largest for 75.3%, across 66 positions as of 30 June 2026.

Does Form 13F show everything Winslow 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 Winslow 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.
