Oakmark Select Fund Eyes Phillips 66 (PSX) as Crack Spreads Tighten
Harris Associates' Oakmark Select Fund is betting on Phillips 66, citing favorable crack spread dynamics as a catalyst for value realization in its first-quarter 2026 outlook.
The Bull Case for Refining Margins
Harris Associates, the investment manager behind the Oakmark Select Fund, is positioning its portfolio to capitalize on a rebound in refining profitability. The firm identifies Phillips 66 (PSX) as a core holding, specifically highlighting the potential for rising crack spreads to drive earnings growth. While the broader market indices have seen volatility, the fund maintains a concentrated approach, focusing on mid and large-cap US equities that it believes are currently trading at a discount to intrinsic value.
Refining margins—the difference between the cost of crude oil and the market price of finished products like gasoline and diesel—remain the primary lever for PSX profitability. Market participants often monitor these spreads as a proxy for sector health. When spreads widen, refining companies see immediate margin expansion, which often leads to free cash flow generation and subsequent capital returns through buybacks or dividends.
Portfolio Strategy and Market Positioning
Oakmark Select’s Q1 2026 letter reveals a strategy that prioritizes value over momentum. By isolating PSX, the managers are expressing a view that the market has undervalued the company's refining footprint and its midstream infrastructure. The fund's performance in the first quarter trailed the S&P 500 (SPX), a common outcome for deep-value funds during periods where high-growth tech names drive index returns.
Traders looking at the energy space should note that refining stocks often act as a cyclical hedge. Unlike pure-play exploration and production companies that correlate directly with the price of WTI Crude (CL), refiners have a more complex relationship with the commodity cycle.

Implications for Energy Traders
For those active in stock market analysis, the focus on PSX suggests a rotation toward companies that can manage overhead while capturing volatility in the energy complex. If crack spreads widen as expected, PSX may see improved valuation multiples relative to the broader energy sector. However, traders should remain aware that these spreads are highly sensitive to both domestic demand for refined products and export capacity constraints, which can fluctuate rapidly based on global geopolitical events.
External factors, such as maintenance schedules at major refineries or regulatory shifts, often create short-term price discovery windows. Investors who use best stock brokers to manage their portfolios should monitor weekly EIA inventory data, as sharp moves in gasoline and distillate stocks often lead to immediate repricing in the refining sector.
What to Watch
Investors should keep a close eye on the following catalysts heading into the next quarter:
- Refinery Utilization Rates: Any drop-off in capacity utilization will compress margins regardless of spread strength.
- Inventory Levels: A build in refined product stocks typically exerts downward pressure on crack spreads.
- Sector Sentiment: Watch for broader institutional flows into energy infrastructure as a signal of defensive positioning.
The conviction behind this position suggests that the fund managers expect a correction in the current valuation of refinery assets. Whether the market agrees will depend on the sustainability of the current spread environment through the upcoming peak demand periods.
