Oakmark is the mutual fund family launched in 1991 by Harris Associates, the Chicago deep-value firm founded in 1976 (about $105bn AUM). Bill Nygren runs the flagship Oakmark Fund and David Herro the Oakmark International Fund, buying businesses at large discounts to intrinsic value and holding them like owners — publishing quarterly fund commentaries, market commentaries and insight articles.

This report argues that active mutual funds (funds where managers pick stocks, not just track an index) aren't dead—they've just failed to deliver what investors need. Many funds are actually closet index funds, with tiny differences from the benchmark, yet charge high fees. The real cost of their active bets is far higher than it looks. Funds like Oakmark, with high 'active share' (how different their holdings are from the index), give you more genuine active management for a lower effective fee. So don't be fooled by low headline fees; check how much a fund truly deviates from the index.
Oakmark's Q4 2023 report notes that while active management funds have been declared "dead" by the market, this claim is exaggerated. In 2022, mutual funds saw net outflows of $960 billion, and as of November 2023, an additional $430 billion had flowed out, making it the second-worst year for the in
This chapter discusses the market challenges and industry skepticism faced by actively managed mutual funds in 2023. Despite the strong performance of U.S. stocks in 2023, actively managed funds still experienced massive capital outflows, leading to a widespread belief that active management is "dead." The report's author counters this view, arguing that the problem lies in funds failing to meet shareholder needs, rather than a structural flaw in the active management model itself.
The author's central judgment is: Actively managed funds are not dead; their struggles stem from industry-specific issues, not a structural failure. This view stands in stark contrast to the market consensus (that active management is being phased out by the indexing trend). Oakmark believes that differentiated strategies—such as a greater focus on shareholder interests, long-term investing, and concentrated holdings—can avoid the industry's common pitfalls.

U.S. large-cap stock funds hold an average of 256 stocks, with an active share of 60% and a stated expense ratio of 1.10%. However, after adjusting for active share, the actual active expense ratio rises to 1.79%, with value funds at 1.49% lower than growth funds at 1.81%
This chapter discusses how actively managed funds can prove their value through differentiated strategies, in response to market claims of their "death." The author points out that many active funds are essentially "index funds" that fail to deliver genuine active management value, while Oakmark distinguishes itself through a clear strategy.
The author's central thesis is that the problem with actively managed funds is not a structural flaw, but rather that many funds are not "active" enough. Investors should focus on a fund's "Active Share"—the degree to which its portfolio differs from the benchmark index—and assess whether fees are reasonable based on this metric. Counterintuitive insight: Low-fee funds (e.g., 0.23%) may have extremely high "active fees" (2.43%) due to very low Active Share (<20%), far exceeding funds with higher fees but high Active Share.
Funds with Active Share below 20% have a nominal expense ratio of only 0.23%, but an active fee ratio as high as 2.43%; in contrast, the Oakmark Fund has an Active Share of 84% and an active fee ratio of only 1.05%, while the Oakmark Select Fund has an Active Share of 93% and an active fee ratio of 1.06%
