Core Viewpoint

Key data points:

Long-term Advantage: The Oakmark Fund's annualized return since inception (12.89%) exceeds that of the Oakmark Select Fund (12.27%) by 0.62 percentage points, and its 10-year return is also 0.31 percentage points higher.
Short-term Divergence: The 1-year return difference is substantial, with the Oakmark Fund at 11.84% versus the Oakmark Select Fund at -0.08%, a gap of nearly 12 percentage points. The 3-month return also diverges, with the Oakmark Fund at 4.24% and the Select Fund at only 0.28%.
Expense Difference: The Oakmark Select Fund's net expense ratio (0.96%) is higher than that of the Oakmark Fund (0.86%), but this expense gap is insufficient to explain the vast return disparity.

Companies/Assets Involved

Oakmark Fund: The better-performing fund, leading in both long-term and short-term returns with a lower expense ratio. The author does not explicitly express a bullish or bearish view, but the data suggest its investment strategy is more effective in the current market environment.
Oakmark Select Fund: The relatively underperforming fund, with a negative 1-year return and a 5-year return (9.81%) significantly lower than the Oakmark Fund's (12.57%). The author does not explicitly express a bearish view, but the data expose its vulnerability in short- and medium-term performance.

Investment Insights

Focus on Recent Performance Divergence When Selecting Funds: The Oakmark Select Fund's 1-year loss contrasts with the Oakmark Fund's profit, indicating that even funds under the same management company can exhibit significant performance divergence due to differences in portfolios or strategies. Investors should not rely solely on long-term historical returns but should also examine recent performance and strategy adaptability.
Expenses Are Not the Sole Determinant: Although the Oakmark Select Fund has a higher expense ratio, the 0.10 percentage point fee difference cannot explain the nearly 12 percentage point return gap, suggesting that stock selection or allocation capability is the primary driver.
Short-Term Performance Can Serve as a Risk Warning: The Oakmark Select Fund's negative 1-year return and marginal positive 3-month return of only 0.28% may indicate that its holdings exposed it to greater risk during the 2018 market volatility. Investors need to assess their own risk tolerance.
