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 says many popular US tech stocks are too expensive and risky. Instead, it suggests looking for cheap, ignored companies with room to improve profits—like Gruma (a Mexican tortilla maker) or FedEx (splitting up its business).

Southeastern (Longleaf Partners) February 2025 Report The report notes a coexistence of "over-selection" and "under-selection" in the current market: U.S. large-cap growth stocks carry elevated risks due to excessive valuations (the S&P 500's price-to-sales ratio is at historical highs), and high-mu
This chapter explores the current market paradox where "excessive stock-picking" and "insufficient stock-picking" coexist. The report points out that large-cap U.S. growth stocks are accumulating risks due to excessive valuations (the S&P 500 price-to-sales ratio is at historical highs), while value investing, being overlooked, offers long-term return opportunities.
The author's core investment argument is: Low-multiple, unoptimized-margin companies are effective over the long term, but require patience. Counterintuitive judgments include:
The weighted average S&P 500 price-to-sales ratio rose to approximately 10.5x in 2024-2025, close to the 12x peak during the 2000 dot-com bubble and significantly above the historical median level (around 3x)
| Company | Role | Key Data | Bullish/Bearish |
|---|---|---|---|
| Gruma | Global leader in tortillas and corn flour | U.S. operations account for over 75% of company value; Gonzalez family holds approximately 50% stake; per-share FCF has steadily grown since initial holding in 2019 | Bullish (undervalued due to Mexico listing, tariff concerns, GLP-1 drug impact) |
| IAC | Slimming-down conglomerate | Owns 100% of Dotdash Meredith (DDM) and over 20% of MGM Resorts; DDM cash flow growing at double digits; IAC valued below $0.50 per dollar, trading at less than 5x DDM+MGM FCF | Bullish (most undervalued holding; Barry Diller more actively involved, potential buybacks or M&A) |
| FedEx | Logistics company | Has announced the spin-off of its Freight business; tariffs are a clear headwind but already partially reflected in the stock price | Bullish (spin-off will bring clarity and accountability, similar to historical spin-off cases) |
