"Oakmark warns that the S&P 500 has evolved into a highly concentrated, risky growth proxy. It argues that the extreme valuation gap relative to Oakmark's low-P/E portfolio presents an exceptional entry point for value-oriented outperformance."
In the 4Q 2025 commentary, Portfolio Manager William Nygren reviews the extreme outperformance of momentum strategies, which delivered double the S&P 500's return in 2025 and marked the second-strongest two-year momentum period since 1998. This trend has penalized active value managers, but it has also created a historically wide valuation gap: the S&P 500 P/E rose 5 points to 22, while the average stock P/E rose only 1 point. With the S&P 500 increasingly expensive and concentrated (35% Tech, largest holding >7%), the Oakmark Fund has structured a highly differentiated portfolio (<5% Tech, largest holding <3%, trading at 13x expected earnings) that maintains its lowest correlation to the S&P 500 since the dot-com bubble. Nygren argues that the broad index is no longer a low-risk holding and that Oakmark is exceptionally well-positioned to benefit when mean reversion occurs.
