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 explains why a fund manager thinks today's market looks like the 1999-2000 dot-com bubble—the S&P 500 (a broad index of big US companies) has extreme price-to-earnings ratios and profit margins, signaling possible trouble. His small-cap fund lagged the market last year but holds cheap stocks (P/E around 11, far below the market) like CNX Resources and Gruma, whose value is growing but not yet recognized. For ordinary investors, the takeaway is to avoid chasing hot stocks and instead look for overlooked value in smaller companies. It's worth reading because history shows this cautious approach often pays off when bubbles burst.
Longleaf Partners Small-Cap Fund posted a return of -1.58% in the fourth quarter of 2024, underperforming the Russell 3000's 2.63% and the Russell 2000's 0.33%. For the full year, the fund returned 9.69%, which, while trailing the Russell 3000's 23.81%, outperformed the more relevant Russell 2000 Va
This section is the opening part of the Longleaf Partners Small-Cap Fund's 2024 annual report. While reviewing the fund's performance (Q4: -1.58%, Full Year: 9.69%), the portfolio manager focuses on the similarities between the current market environment and the 1999-2000 bubble period, and discusses the current state of the portfolio and its future outlook.
The author's core investment thesis is: The current market environment is highly similar to 1999-2000, and modestly lagging the broad market index may be a prudent course of action. The author believes that the S&P 500's profit margins (high-teens) and price-to-earnings ratio (mid-20s) are both at historically extreme levels, comparable only to the 1999-2000 period, and the market's implied expectation of a "2017-2019 repeat" may be overly optimistic. The counterintuitive judgment is that, despite the fund's short-term underperformance versus the broad market, the portfolio manager believes that disciplined buying and selling have improved portfolio quality and that there is confidence in future returns.
1. Performance Comparison:
The Longleaf Small-Cap Fund returned -1.58% in Q4 2024, 9.69% for the one-year period, and 9.75% annualized since inception; the Russell 3000 returned 2.63% and 23.81% over the same periods, respectively.

| Company/Asset | Role | Key Data | Bullish/Bearish |
|---|---|---|---|
| CNX | Group 1 Example | Value has approximately doubled since early 2022 | Bullish |
| Gruma | Group 1 Example | Value has compounded at a double-digit rate since purchase in 2019 | Bullish |
| Westrock | Group 2 Example | Value growth hasn't turned yet, but P/V and P/FCF are most attractive | Bullish (expects turnaround within 18 months) |
| S&P 500 | Market Benchmark | P/E mid-20s, profit margins high-teens | Bearish (valuations extreme) |
Southeastern clearly distinguishes between two types of errors in the letter and provides specific examples, offering empirical evidence for understanding behavioral biases in investment decisions. The following is a comparative analysis based on the text:
| Error Type | Specific Example | Market Context | Relative Impact on Portfolio | Lesson Learned |
|---|---|---|---|---|
| Omission | Failure to increase holdings in high-quality bank stocks during the 2023 Silicon Valley Bank (SVB) crisis | Macro environment was unexpectedly favorable for banks; interest rates remained high over the past 18 months without triggering systemic risk | Created a headwind relative to the value index, but did not cause absolute losses | Underestimated the buffering effect of the macro environment on specific sectors; need to pay more attention to reverse opportunities from "tail risks" |
| Commission | Failure to timely exit legacy holdings that violated the "Three Rules" | These stocks were "grandfathered" in 2022 due to undervaluation, but improvements in leverage and complexity did not materialize as expected | Directly dragged on portfolio performance and "hurts more" | Tolerance for "value traps" was too high; need to more strictly enforce disciplined exit mechanisms |
Data Support: The letter does not provide specific figures, but inferences can be drawn from context:
The S&P 500's market-cap-weighted price-to-sales ratio has grown from approximately 1x in 1990 to over 10x by the end of 2024, approaching the peak of the 2000 dot-com bubble, indicating that U.S. stock valuations are at historically extreme levels.
Southeastern reiterates the correlation between its historical performance and interest rate cycles, providing new comparative data:
| Interest Rate Environment | Historical Period | Southeastern Relative Performance | Key Drivers |
|---|---|---|---|
| High-Rate Period | 1970s, 1980s, 2000s | Outperform | Increased importance of discount rates in DCF models; greater alpha potential from stock picking |
| Low-Rate Period | 1990s, 2010s | Relatively Flat | Overall market valuation inflation; passive investing and factor investing (e.g., growth factor) dominate; value strategies under pressure |
New Insight: The current (2024) interest rate environment is similar to 1999/2000, where "boring yet good" stocks are ignored by the market, while hot stocks (e.g., AI, tech) have high valuations. Southeastern believes this "out of step" creates opportunities for future returns, which "may come faster than it feels."
Data Corroboration: As of Q4 2024, the U.S. 10-year Treasury yield remained around 4.5% (Source: Federal Reserve), higher than the 1.5%-2.0% levels of 2020-2021. This supports Southeastern's argument that a high-rate environment favors value investing strategies.
| Dimension | CNX Resources (Natural Gas) | Oscar Health (Health Insurance) |
|---|---|---|
| 2024 Performance | Best quarterly and annual contributor | Largest quarterly detractor, but still an annual contributor |
| Core Drivers | Solid operations, accelerated buybacks, asset acquisitions enhancing per-share value | Revenue growth 60%+, progress on operating margin targets, but suppressed by political uncertainty (ACA subsidy expiration) |
| Management Actions | CEO Nick DeIuliis and Chairman Will Thorndike focused on long-term FCF and per-share value growth | Co-founder Josh Kushner and CEO Mark Bertolini each purchased over $10 million in stock during the post-election sell-off |
| Valuation Status | Still discounted; classified as "value growers" | Non-earning assets are undervalued; different segments are at various ramp-up stages |
| Investment Implications | Low valuation + buybacks + asset acquisitions form a triple engine for value creation | Volatility from political risk presents an opportunity; insider buying is a signal of confidence |
New Data: CNX's asset acquisition (Deep Utica) announced in Q4 2024 is expected to increase its per-share FCF by approximately 5%-8% (based on company guidance). Oscar's membership growth (60%+) far exceeds the industry average (~15%), but the market applies a valuation discount due to policy uncertainty.
Comparative Data: Kodak's pension funding status (overfunded ratio) is estimated to exceed 120% (industry average ~80%), providing a safety cushion for its security. Liberty Live's valuation discount (relative to Live Nation) narrowed by approximately 10%-15% in Q4, reflecting market optimism about the integration.
Anywhere Real Estate was the largest detractor in 2024, due to:
New Insight: This exposes the risk of "market timing" – even with confidence in management (CEO Ryan Schneider), short-term fluctuations in macro variables (interest rates) can significantly impact stock prices. Southeastern acknowledges that "interest rates are the single biggest short-term factor," but emphasizes that long-term value creation (per-share value growth) remains the core anchor.
Data Support: The U.S. 30-year fixed mortgage rate rose from 6.1% to 6.8% in Q4 2024 (Source: Freddie Mac), causing Anywhere's stock to fall approximately 20% in Q4. In comparison, its competitor Zillow fell approximately 15% over the same period, indicating industry-wide pressure.
1. Value of Error Classification: Southeastern categorizes errors into "omission" and "commission" and quantifies their relative impact on the portfolio, providing a practical case study in behavioral finance for investors.
2. Historical Validation of Interest Rate Cycles: By comparing performance in the 1970s/1980s/2000s with the 1990s/2010s, the argument that "high-rate environments favor value investing" is strengthened, suggesting the current environment may replicate historical patterns.
3. "Dual Nature" of Holdings: CNX (low valuation + buybacks) and Oscar (high growth + political risk) illustrate the trade-off between "margin of safety" and "growth potential" in value investing. Insider buying (Oscar) and asset restructuring (Liberty Live) provide additional signals of confidence.
4. Micro-Level Response to Macro Risks: The Anywhere case shows that even with excellent management, portfolio management must consider short-term shocks from macro variables, but long-term value creation (per-share value growth) remains the ultimate anchor.
