Exceptional Fund Performance and Dividend Growth
The Thornburg Investment Income Builder Fund achieved a remarkable I share return of 36.93% for the 12-month period ending December 31, 2025, significantly exceeding the blended benchmark return of 17.60%. This outstanding performance highlights the fund's successful investment strategy, which prioritizes dividend-paying companies with resilient business models, robust capital structures, and strong market positioning. The fund's ability to identify and invest in such companies across various sectors, including telecommunications, financials, and technology, contributed significantly to its superior returns. Additionally, the fund increased its ordinary dividends to $1.27 per I share in 2025, representing a 2.6% increase over the previous year, demonstrating its commitment to consistent income distribution to shareholders.
The fund's outperformance was primarily driven by strategic allocations to sectors that exhibited strong growth and stability. Top holdings in telecommunications, financials, and technology played a crucial role in enhancing the fund's overall returns. This disciplined approach to portfolio construction, focusing on companies with durable competitive advantages and attractive valuations, allowed the fund to capitalize on market opportunities while mitigating risks. The fund's equity portfolio trades at a 14.2x 2025e P/E and offers a 4.2% yield, which are more attractive metrics compared to the MSCI ACWI’s 21.6x P/E and 1.7% yield. This favorable valuation and yield profile further underscore the fund's potential for continued strong performance and income generation in the future.
Strategic Portfolio Management in an Uncertain Global Economy
Amidst ongoing geopolitical tensions, including the conflict in Ukraine, and persistent inflation concerns in the U.S., the Thornburg Investment Income Builder Fund has maintained a strategic portfolio composition. The fund remains focused on companies with strong capital structures and significant market presence, ensuring resilience against economic headwinds. Incoming economic data suggests a global economy that, while uncertain, has so far resisted a recession, influenced by evolving U.S. trade policies. The fund's asset allocation reflects a balanced approach, with approximately 84% in equities and 16% in interest-bearing debt and cash, designed to optimize returns while managing risk through sector diversification and currency hedging strategies.
The fund’s management of risk is a critical component of its strategy, particularly in a volatile global economic environment. By diversifying across various sectors and employing currency hedging, the fund aims to protect capital and reduce the impact of adverse market movements. The emphasis on companies that are integral to their respective markets provides a defensive characteristic to the portfolio, allowing it to navigate periods of economic instability more effectively. This strategic positioning, combined with a commitment to dividend-growing companies, enables the fund to pursue both capital appreciation and a reliable income stream for investors, even as global economic conditions continue to evolve and present new challenges and opportunities.
