How We Invest: Active by Nature. Disciplined by Design.

Thornburg Investment Management
19 Jun 2025
2 min read

Discover Thornburg’s investment philosophy: a research-driven, high-conviction approach rooted in disciplined, long-term thinking—focused on uncovering overlooked opportunities and building resilient portfolios.

Forty years ago, Thornburg was founded as an independent investment firm on a clear principle: disciplined, bottom-up and research-led investing leads to better long-term outcomes for our clients. From our base in Santa Fe, New Mexico—far from the noise and short-termism of Wall Street—we take a broader, more patient view of markets, shaped by deep understanding and perspective.

We pursue a high-conviction, research-driven approach to global markets—seeking mispriced opportunities across sectors and asset classes. Guided by a generalist mindset and disciplined risk assessment, we invest only when long-term reward outweighs the risk. Our focus is on durable business models, resilient cash flows, and strong governance—particularly during periods of market dislocation.

"We invest only when long-term reward outweighs the risk—guided by independent thinking, disciplined research, and a commitment to our clients’ goals."
Christian Hoffmann, Head of Fixed Income

Our culture reinforces this approach. We value clarity over complexity and collaboration over hierarchy. With a flat structure and open exchange of ideas, our portfolio managers benefit from the full breadth of insight across the firm. This cross-pollination of perspectives strengthens our ability to make informed, forward-looking decisions for our client.

Santa Fe is more than our location—it reflects our mindset. Distance from financial centres fosters independent thinking, long-term perspective, and accountability. It allows us to stay focused on what matters: building resilient portfolios that are aligned with our clients’ goals.

In short, we combine independent thinking and collaborative discipline to deliver active strategies designed to endure—and built to serve clients for the long term.

Explore our approach to investment success.
