Southeastern Asset Management is a Memphis-based deep-value firm founded in 1975 by O. Mason Hawkins to exploit the bargains left by the 1973-74 bear market. Its flagship Longleaf Partners Funds (launched 1987) invest employees' own money alongside clients'. Following Graham's discipline and its "Business, People, Price" framework, it runs concentrated books of 15-25 undervalued stocks held for the long term — famously closing funds to new investors when opportunities were scarce. CEO and Head of Research Ross Glotzbach now leads the firm, which publishes quarterly Longleaf fund commentaries and Research Perspectives notes.

This article covers Southeastern's Global Fund results for Q3 2023. Instead of chasing the "Magnificent Seven" tech giants (with an average P/E of 29), the fund bought high-quality companies at a low P/E of just 12.5, betting they will outperform when market enthusiasm fades. The fund lost 3.45%, but holds cheap stocks with real upside. For ordinary investors, it’s a reminder to avoid overpriced darlings and look for undervalued firms where management is buying back shares. It’s worth reading as a case study in disciplined value investing.

This chapter discusses the performance and portfolio strategy of the Longleaf Partners Global Fund for the third quarter of 2023. The market was influenced by high inflation, prolonged high interest rates, and a weak Chinese economy, leading to a strong risk-off sentiment, with only the energy and communication services sectors posting positive returns. The fund declined 3.45% during the quarter, roughly in line with the FTSE Developed Index (-3.43%).
The fund's P/V ratio is at a low 60% level, cash accounts for 4.0%, and it holds 25 stocks
The report's core investment thesis argues that by holding high-quality, undervalued companies, the fund has the potential for excess returns in a market characterized by extreme valuation dispersion. A contrarian judgment is that the fund completely avoids the "Magnificent Seven" and 11 other of the most actively traded U.S. stocks globally (with a market cap exceeding $11 trillion and a weighted average P/E of 29x), instead holding a portfolio at a 12.5x P/E, well below the FTSE Developed's 15.54x. The author believes these mega-cap stocks face pressure from intensifying competition and rising interest rates, while the fund's portfolio companies are executing well operationally, delivering a 26% return over the past 12 months, and are poised to achieve relative outperformance in various market environments going forward.
The Global Fund returned -3.45% in Q3, 14.44% year-to-date, 26.11% over one year, and an annualized 4.19% since inception
