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 the Longleaf Partners Fund performed in early 2023, when bank failures and a tech stock bounce dominated markets. The fund avoided banks and owned few tech stocks, so its results differed from indexes. For everyday investors, the key takeaway: don't chase big tech like Apple or Microsoft—their rebound may be short-lived. Banks are risky because high debt makes them hard to value. Instead, look at beaten-down stocks like Warner Bros Discovery and FedEx, which the fund sees as undervalued. Worth reading for concrete examples of finding bargains during turmoil.

This section discusses the performance of the Longleaf Partners Fund in the first quarter of 2023 and the prevailing market environment. The market was dominated by two major factors: the banking crisis triggered by the collapse of Silicon Valley Bank (SVB), and a short-term rebound in technology/growth stocks that had declined in 2022. The fund had no direct exposure to banks and limited holdings in technology stocks, resulting in a performance that diverged significantly from the indices.
The author's core investment argument is that bank stocks are difficult to value over the long term due to high leverage and a lack of transparency, while certain large-cap technology stocks (such as Apple and Microsoft) remain overvalued, making their rebound potentially short-lived. The fund's top five contributors were mostly stocks that had been excessively punished in prior years, and the author believes these companies still have significant upside potential.
The fund's P/V ratio is in the low-60s%, with cash at 5.3% and a total of 22 holdings
