Common questions
What are GW&K Investment Management’s 13F holdings worth?

What is GW&K Investment Management’s largest 13F holding?
MACOM TECHNOLOGY SOLUTIONS H (COMMON) was the largest position at $241,439, or 1.9% of reported 13F value, as of 30 June 2026.
How concentrated is GW&K Investment Management’s 13F portfolio?
The ten largest positions accounted for 12.7% of reported value and the twenty-five largest for 25.3%, across 1,109 positions as of 30 June 2026.
Does Form 13F show everything GW&K Investment 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 GW&K Investment 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.
Answered from this filing and the prior quarter's.
