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 fund commentary warns that today's stock market is driven by a handful of giant tech stocks, much like the 2000 dot-com bubble. It suggests those stocks could crash soon. But the fund itself avoided those hot names and still beat the market by investing in companies like Live Nation (concert ticketing), IAC (digital holdings), and Millicom (telecom in Latin America) — all improving their own businesses. For everyday investors: don't chase hype; look for bargains where companies are fixing themselves. This report offers a useful contrarian perspective.
Southeastern (Longleaf Partners) July 2023 report shows that the Global Fund returned 3.21% in the second quarter and 18.53% year-to-date in the first half, outperforming the FTSE Developed Index (14.86% in the first half), despite lacking exposure to the information technology sector and being over
This chapter is the introduction to the quarterly report of Southeastern (Longleaf Partners) Global Fund, released in July 2023. The report reviews the fund's performance in the second quarter and first half of 2023, with a focus on analyzing the current market environment, which is dominated by a handful of mega-cap growth stocks. It draws a parallel to the early stages of the 2000 internet bubble. The report also details the fund's portfolio activity, as well as the key contributors and detractors among individual holdings.
The author's core investment thesis is that the few mega-cap tech stocks currently driving the market (similar to the early 2000s internet bubble) are at a stage where profit margins are peaking, competition is intensifying, and regulatory risks are rising, potentially leading to a more severe downturn. However, the fund's strong relative performance does not rely on a market correction but is instead based on the operational improvements and robust fundamentals of its portfolio companies. The report also highlights that the fund outperformed the FTSE Developed Index (14.86%) in the first half of 2023 with an 18.53% YTD return, despite having no exposure to the information technology sector and an overweight position in consumer discretionary.
The Global Fund returned 3.21% in Q2 and 18.53% YTD, compared to the FTSE Developed Index's returns of 6.72% and 14.86%, respectively. The fund's returns across all longer-term periods lagged the benchmark.
During the 2000 internet bubble, the NASDAQ 100 first fell 35.7%, rebounded 35.6%, and then plunged a further 80.4% over the next 25 months.
Comparative Data Table:
The NASDAQ 100's trajectory from 2020 to 2023 resembles 2000, first falling 35.0% and then rebounding 42.9% over six months.
