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 commentary from a small-cap fund says their portfolio returned 3.7% in the second quarter. The manager warns that mega-cap tech stocks (like Apple, Microsoft) may be in a bubble similar to the 2000 dot-com crash: profit margins are peaking, competition and regulation are rising. Instead, they own small- and mid-cap companies (tortillas, beer, insurance, sports teams) with strong balance sheets and pricing power, trading at just 60% of estimated value. They also highlight bonds of Lumen, backed by hard assets, as a better risk-reward than its stock. Takeaway: don't chase big tech; look for unloved small caps or distressed debt with a margin of safety.
Longleaf Partners Small-Cap Fund 2023 Second Quarter Report The fund posted a return of 3.70% for the quarter, bringing its year-to-date gain to 8.10% as of the first half of 2023. This performance outpaced the Russell 2000 Value Index (up 2.50% in the first half) but slightly lagged the Russell 200
This section is the opening part of the Longleaf Partners Small-Cap Fund's second quarter 2023 report, primarily reviewing the fund's performance for the quarter and the first half of the year, and articulating the fund manager's assessment of the current market environment. The report notes that investors are rotating from small- and mid-cap stocks into mega-cap growth stocks, but the author believes this trend may mirror the early stages of the 2000 dot-com bubble, with mega-cap tech stocks facing peak profit margins, intensifying competition, and regulatory risks, potentially leading to significant declines.
Fund P/V ratio approximately 60%, cash position 4.6%, portfolio of 20 holdings
The author's core investment thesis is that the fund has achieved absolute and relative returns in the current market environment through differentiated holdings (e.g., financials and real estate) and defensive allocations (stable brand companies in tortillas, beverages, insurance, sports, etc.), and this differentiated positioning will serve as a source of future outperformance. The counterintuitive judgment is that the author believes mega-cap tech stocks are not a safe haven but rather resemble the early stages of the 2000 dot-com bubble, potentially experiencing more severe declines; meanwhile, the fund's small- and mid-cap holdings, though viewed by the market as more volatile cyclical companies, possess strong balance sheets and pricing power, enabling value creation in challenging markets.
