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 report covers how Longleaf Partners Fund performed in Q3 2024. It earned 10.42% (beating major indexes) but deliberately trimmed some winners (like Kellanova, bought out by Mars) and raised cash to 22.6%. The manager thinks stocks are still undervalued but sees risk ahead, so they keep a bigger safety cushion. For regular investors, this is worth reading because it shows how professionals stay disciplined even after good returns, and why focusing on free cash flow and stock buybacks matters more than chasing hot stocks.
Longleaf Partners Fund Q3 2024 Returned 10.42%, Outperforming the S&P 500 (5.89%) and Russell 1000 Value (9.43%), with Half of Holdings Delivering Double-Digit Returns The core view is that the market is beginning to recognize the value of its holdings, but the fund raised its cash position to 22.6%
This section summarizes the performance, portfolio adjustments, and core investment logic of the Longleaf Partners Fund in the third quarter of 2024. In terms of market environment, the fund outperformed major indices but raised its cash position to 22.6%—above normal levels—by reducing holdings in strong-performing stocks, thereby increasing the portfolio's margin of safety.
The author's core investment argument is that the market is beginning to recognize the value of the fund's holdings, but the fund actively reduced positions in strong performers and maintained a high cash position to address the historic valuation gap between the index and its holdings. The counterintuitive judgment is that despite the fund's strong performance, the author is not fully bullish but instead emphasizes maintaining defensiveness through position reductions and cash reserves, believing that signs of market "rationality" are just emerging.
