Oakmark is the mutual fund family launched in 1991 by Harris Associates, the Chicago deep-value firm founded in 1976 (about $105bn AUM).

This report from Oakmark says that when investing in energy stocks, don't try to predict oil prices—they swing wildly and are nearly impossible to get right. Instead, focus on the companies themselves: how disciplined their management is, how low their costs are, and how strong their balance sheets are. Since energy firms often need to reinvest more than their entire market value, the quality of their decisions matters more than oil prices. For ordinary investors, this means you can profit from volatility by sticking with well-run companies that can survive downturns and even make smart acquisitions. It's a calm, thoughtful approach to a famously chaotic sector.

The central question addressed in this chapter is: How can a value investment firm employing a bottom-up methodology make long-term investments in the highly volatile energy sector? The report notes that short-term oil price movements are extremely difficult to predict—just three months ago, oil fell to a four-year low of approximately $55 per barrel due to oversupply, while recently it has surged past $100 per barrel amid supply shortage concerns, and could even head toward $150. Such violent fluctuations cause many investors to either chase trends or sit on the sidelines due to uncertainty.
The author’s core investment argument is: Do not bet on macro oil price forecasts in energy investing; instead, focus on evaluating the companies themselves. The report contends that short-term oil price predictions are almost never consistently accurate, but long-term oil prices are constrained by producers’ cost structures and are therefore relatively stable. Hence, the investment edge comes from assessing a company’s cost curve, capital allocation discipline, and management quality, turning volatility into opportunity.
Counterintuitive insight: Despite sharp short-term oil price swings, the inflation-adjusted average oil price has remained “roughly similar” over the past 5, 10, and 25 years. This long-term stability stems from the “gravitational pull” of producers’ cost structures—when oil prices are too low, producers reduce activity, leading to supply shortages; when too high, they increase activity, causing oversupply.
Real oil prices fluctuated wildly from 2001 to 2026, peaking near $200/barrel in 2008 and troughing at about $25 in 2020, while the long-term historical average remained stable in the $75–100 range
