The PRI is the world's leading proponent of responsible investment. It works to understand the investment implications of environmental, social and governance (ESG) factors and to support its international network of investor signatories in incorporating these factors into their investment and ownership decisions.

Our Story & Philosophy

A Way of Seeing

Founded in Santa Fe, New Mexico—deliberately away from the noise of Wall Street—Thornburg’s foundation encourages reflection, integrity, and thoughtful decision-making. As a privately owned, global investment firm, we combine global perspectives with rigorous qualitative and quantitative analysis to identify high-conviction ideas across asset classes, geographies, and market cycles.

What Sets Us Apart

Seeking Investment Excellence

We bring together global perspectives to uncover opportunities and make disciplined, research-driven decisions. Our active portfolios aim to deliver alpha and consistent, risk-adjusted returns aligned with long-term goals.

Committed to Client Success

As an independent firm, we put clients first—acting with integrity and transparency. Beyond portfolio management, we provide tailored insights and practical support to help clients grow and succeed.

Investing in Shared Prosperity

We believe in making a meaningful impact—locally and globally. From sustainable practices to community support, we prioritize long-term decisions that benefit clients, colleagues, and future generations.

Global Investment Generalists

In pursuit of investment truth

Thornburg’s team brings holistic expertise across geographies, sectors and asset classes to the investment process. It is an iterative approach, where continual and open communication among portfolio managers and research is expected. This is how ideas evolve into investment theses and where validation begins to uncover investment truth. We employ a full complement of fundamental analysis and other proprietary research techniques to evaluate an individual investment. Each idea is debated from multiple viewpoints and where it sits in a complex and interconnected global market. A high-conviction position is a decision we make together.

Risk Management

Oversight at All Levels

Risk management is a multi-faceted question. We look across the functions of our firm on a systematic basis to ensure that our investment process, trade functions, accounting and reporting protocols, and operations and technology integrate high standards of risk management.

Within our portfolios, risk is managed through a combination of qualitative portfolio manager peer review and quantitative techniques, providing robust data on factor exposures, credit, interest rates and volatility metrics. Investment risk is analyzed through intensive, bottom-up fundamental analysis and valuation for individual investments.
