Longleaf Partners Fund released its portfolio updates and investor commentary for the second quarter of 2026 [1].
The report highlights the challenges of maintaining a value-oriented strategy in a market heavily influenced by a few high-growth sectors. Because the fund avoids overextended valuations, it often misses short-term surges in specific industries, which can lead to significant relative underperformance against broader benchmarks.
Managed by Southeastern Asset Management, the fund said a vast majority of its recent struggle was due to its sector allocation [2]. Specifically, almost 90% of Longleaf Partners Fund's relative underperformance in the quarter came from its underweight position in information technology [3].
This gap suggests that while the fund's core holdings may remain stable, the lack of exposure to the tech rally created a widening divide between its returns and the overall market. The commentary focuses on the discipline required to avoid sectors that the firm deems overpriced, even when those sectors drive the majority of market gains.
Investment teams at Southeastern Asset Management continue to monitor portfolio updates across their U.S. and international funds [1]. The firm said it maintains its commitment to a long-term value approach, which prioritizes the intrinsic value of a company over momentum-driven price increases.
Throughout the second quarter of 2026 [1], the fund's strategy remained centered on identifying undervalued assets. This approach often results in periods of volatility when the market is led by a narrow group of stocks, particularly in the technology space.
“Almost 90% of Longleaf Partners Fund's relative underperformance in the quarter came from its underweight in Information Technology.”
The fund's struggle illustrates the ongoing tension between traditional value investing and the dominance of the technology sector. By remaining underweight in tech, Longleaf Partners is betting that current valuations are unsustainable and that a market correction will eventually favor the undervalued companies in its portfolio.
