Columbia Threadneedle Investments announced today that it has been ranked by Barron’s as one of the top fund families in the nation, earning top‑ten positions across the 1‑, 5‑, and 10‑year performance periods in its Best Fund Families of 2025 ranking.

• 10 th out of 46 fund families for 1‑year performance
• 10 th out of 42 fund families for 5‑year performance
• 5 th out of 42 fund families for 10‑year performance

“We are proud to deliver investment results that place us among the strongest performers in the industry not just over the past year, but over the long term,” said William Davies, Global Chief Investment Officer at Columbia Threadneedle Investments. “Achieving top ten rankings across 1- and 5-year periods, and top five over ten years, underscores the strength of our global research platform, the discipline of our investment process, the expertise of our talented team members, and our commitment to delivering long‑term value for clients.”

Columbia Threadneedle’s investment process is driven by close collaboration between globally connected portfolio managers and research analysts, who generate forward-looking insights and drive impactful outcomes for clients across asset classes. This active exchange of fundamental and quantitative perspectives ensures that portfolio construction is informed by diverse viewpoints and a rigorous, research‑intensive approach.

Barron’s Best Fund Families Methodology

Barron’s evaluates fund families based on the asset‑weighted returns of their actively managed funds relative to peers in their respective Lipper categories. Key components of the methodology include:

• Each fund’s performance is ranked within its LSEG Lipper category on a percentile basis.
• Rankings are asset‑weighted relative to the fund family’s other assets in its general classification, meaning larger funds have a proportionally greater impact on a firm’s overall score.
• Excluded from consideration are index funds, but actively managed ETFs and so-called smart-beta ETFs, which are passively managed but created from active strategies, are included.
• Finally, the score is multiplied by the weighting of its general classification, as determined by the Lipper universe of funds.

To qualify, a firm must offer a minimum number of funds across equity and fixed income categories.
