Thornburg Among First to Launch Actively Managed ETF Share Classes

Why It Matters

The new ETF share classes give investors a more liquid, tax‑efficient way to access Thornburg’s high‑conviction strategies, accelerating the shift toward actively managed ETFs in a market dominated by passive products.

Key Takeaways

• Thornburg adds Nasdaq‑listed ETF share classes for TAOZ and TFGZ.
• Firm’s active ETF platform now exceeds $600 million in assets.
• Exemptive relief enables mutual‑fund portfolios to issue ETF share classes.
• First firm to list mutual‑fund‑based active ETFs on Nasdaq.

Pulse Analysis

The active‑ETF segment has accelerated since the SEC granted exemptive orders that let managers pair mutual‑fund portfolios with exchange‑traded share classes. Thornburg Investment Management, a privately owned firm with roughly $57 billion in client assets, leveraged that regulatory shift to expand its ETF platform, which launched its first active ETF in January 2025 and now holds more than $600 million. By being among the earliest adopters, Thornburg signals confidence that investors are demanding actively managed, high‑conviction strategies that can be bought and sold like traditional ETFs, narrowing the gap between passive and active product offerings.

The newly listed Thornburg American Opportunities Fund (TAOZ) and Thornburg Focus Growth Fund (TFGZ) bring the firm’s equity‑focused, fundamental‑research approach to a Nasdaq‑listed ETF structure. Investors gain intraday pricing, lower minimums and the potential tax‑efficiency associated with ETF share classes, while still accessing the same underlying portfolio as the mutual‑fund shares. Both funds target mid‑ to large‑cap U.S. equities, with the American Opportunities fund emphasizing value‑oriented opportunities and the Focus Growth fund concentrating on high‑growth companies. The dual‑share‑class model also offers financial advisors flexibility in meeting client preferences for liquidity and cost.

Thornburg’s move puts pressure on other active managers to consider similar multi‑class structures, especially as competition intensifies from both traditional mutual‑fund houses and pure‑play ETF sponsors. The Nasdaq listing enhances visibility and may attract a broader retail audience that typically gravitates toward exchange‑traded products. As the active‑ETF market is projected to surpass $200 billion in assets by 2028, firms that can combine rigorous research with the operational advantages of ETFs are likely to capture a larger share of inflows. Thornburg’s early adoption could therefore translate into sustained growth for its active‑ETF platform.
