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 is a letter from a fund that invests in small companies. In 2022, the fund lost 19%, slightly better than the overall small-company market but worse than a similar value-focused index. The manager admits the problem wasn't picking bad stocks but making mistakes in how they managed the portfolio: they bet too heavily on a few stocks, tolerated too much debt, and misjudged the timing on complex firms. They now set three new rules: no single stock over 6.5% of the fund; for companies with high debt (net debt over 3 times earnings), use a stricter valuation method; and only invest in holding companies with top-tier partners. For ordinary investors, this is a useful reminder that even good investments can lose money if you overpay or over-concentrate. Worth reading because the manager honestly admits errors and changes course, which is more credible than just talking up the future.
Longleaf Partners Small-Cap Fund Q4 2022 Performance The Longleaf Partners Small-Cap Fund rose 4.74% in the fourth quarter of 2022 and declined 19.27% for the full year, slightly outperforming the Russell 2000 (which fell 20.44% for the year). The fund's price-to-value (P/V) ratio stood at a high 50
This chapter is the opening section of the Longleaf Partners Small-Cap Fund’s fourth-quarter 2022 letter. The report reviews the fund’s performance in 2022 (full-year -19.27%) and reflects on the underlying reasons for the underperformance. The author believes that while short-term volatility may persist, this is merely the beginning of a performance improvement, and proposes three new investment disciplines to correct past mistakes.
The author’s core investment argument is that the fund’s underperformance stems not from a lack of stock-picking ability, but from systematic errors in portfolio management decisions and investment timing. The counterintuitive judgment is that although the 2022 macro environment (rising interest rates, market returning to rationality) should have favored value investing, the fund did not benefit from it. Instead, it underperformed expectations due to its own mistakes (excessive concentration in holdings, overly high tolerance for highly leveraged companies, and premature judgments on complex holding companies).
1. Limit single stock weight: No stock is allowed to exceed a 6.5% position for an extended period. Data shows that stocks held at high weights for a long time tend to perform worse.
2. Leverage limit: When a company’s net debt/EBITDA exceeds 3x, the core valuation metric shifts from P/V (price-to-value ratio) to P/EV (price-to-enterprise value ratio). The author notes that a highly leveraged company with a P/V of 65% may have a P/EV close to 80%, implying a smaller margin of safety. For companies with leverage above 4x, the requirement is a P/EV below 60% (corresponding to a P/V of 40% or lower).
3. Holding company investment criteria: Must require higher-quality partners (e.g., Berkshire Hathaway, Liberty Media, EXOR level), and when a holding company has publicly traded subsidiaries, the overall value calculation must use the lower of each subsidiary’s price or value.

Market divergence intensified in 2022, but the portfolio generated excess returns by focusing on profitable companies (Westrock, Gruma), asset divestitures (Lumen), and cyclical mispricing (MSG, Anywhere). Current valuations are at historical lows, and management actions are accelerating, laying the foundation for a rebound in 2023.
