Friday (July 31) during U.S. stock trading, the energy sector became the absolute focus of the market. Stimulated by the surge in international oil prices, the S&P 500 Energy Index rose 5.2% at one point, marking its largest single-day gain since October 2024. Oil giants like ExxonMobil (XOM) and Chevron (CVX) saw their stock prices rise collectively, with many energy stocks gaining over 4%. Against the backdrop of lackluster tech stock performance, the strength of the energy sector provided important support for the broader market.

Risk Aversion and Supply Contraction Resonate, International Oil Prices Surge Over 5% in a Single Day

The direct trigger for today's oil price surge came from the renewed escalation of geopolitical risks in the Middle East. According to reports by multiple foreign media outlets, oil tankers were attacked near the Strait of Hormuz, causing market concerns about crude oil supply disruptions to rise sharply. Meanwhile, sources within OPEC+ revealed that major oil-producing countries are considering delaying the production increase plan originally scheduled for September to the fourth quarter to cope with weak demand and high inventory pressures. With these dual positives combining, WTI crude oil futures main contract touched $84.5 per barrel at one point during trading, while Brent crude oil broke the $88 mark, both hitting two-month highs.

In fact, this round of oil price increases is not an isolated event. Over the past month, international oil prices have cumulatively risen by about 12%, mainly driven by the peak season for U.S. summer travel demand and boosted confidence in economic recovery from expectations of interest rate cuts by major global central banks. However, today's explosive gain is clearly the result of the combined effect of geopolitical risk premiums and expectations of supply contraction.

Oil Giants Lead Gains, Energy Stocks Rally Broadly

Driven directly by the surge in oil prices, individual energy stocks performed exceptionally well. As of the time of writing, ExxonMobil's stock price rose 4.8% to $126.3 per share, hitting a record high; Chevron gained 4.5%, breaking the $170 mark. Additionally, ConocoPhillips (COP) rose 5.2%, and Occidental Petroleum (OXY) surged 6.1%, becoming one of the biggest gainers among S&P 500 components.

Notably, small and medium-sized oil service companies and shale oil producers showed stronger resilience. EOG Resources rose 5.6%, and Diamondback Energy rose 5.9%. Analysts pointed out that rising oil prices combined with cost control are expected to significantly improve the future free cash flow of these companies, thereby increasing shareholder returns. The oilfield service sector also benefited, with Halliburton (HAL) and Schlumberger (SLB) rising 4.2% and 3.8% respectively, indicating that the market's revaluation of the entire energy industry chain is accelerating.

Capital Flow: Energy ETFs See Record Net Inflows

Capital is the most sensitive. According to Bloomberg data, during the early trading session today, the Energy Select Sector SPDR Fund (XLE) attracted a cumulative net inflow of $470 million, poised to set a record for the largest single-day inflow this year. At the same time, ETFs tracking high-dividend energy stocks were also favored, reflecting that institutional investors are rotating from the tech sector to the energy sector.

Goldman Sachs' commodity strategy team stated in their latest report that the global crude oil market is currently in the "early stages of supply tightening," and expects the average price of Brent crude oil to remain above $85 in the third quarter. The team also upgraded the rating of large oil stocks, believing that in an environment of rising inflation expectations and high tech stock valuations, energy stocks possess both defensive and offensive attributes.

Macro Logic Behind Energy Strength: Inflation Concerns and Fed Path

The strength of the energy sector is not just a carnival for individual stocks, but may also have a chain reaction on the macroeconomy. The market worries that sustained rising oil prices will push up inflation expectations, thereby affecting the Federal Reserve's monetary policy path. Although the Q2 GDP data released earlier this week exceeded expectations, the core PCE price index still showed stubborn inflation. If oil prices move further up, it may put the Fed in a dilemma at the September FOMC meeting.

The CME FedWatch Tool shows that traders' probability of a 25 basis point rate cut in September dipped slightly from 68% yesterday to 62%. While a rate cut remains the baseline scenario, oil price risk is becoming a new variable. Whether the energy sector's rise can sustain depends to some extent on the trend of crude oil prices in the coming weeks.

Institutional Perspective: Energy Stocks Still Have Room for Valuation Recovery

From a valuation perspective, the forward P/E ratio of the S&P 500 energy sector is currently only 11.8x, significantly lower than the market's overall 21.5x. Even after today's surge, the overall dividend yield of energy stocks remains as high as 4.2%, making them extremely attractive in a yield-scarce environment.

Morgan Stanley analysts believe that unless a severe economic recession occurs, energy stocks are expected to gain another 15% to 20% return within the next 12 months. The bank is particularly bullish on integrated oil companies with low-cost assets and strong balance sheets, as well as midstream companies that can benefit from liquefied natural gas exports.

Meanwhile, some headwinds cannot be ignored. If OPEC+ ultimately decides to increase production as originally planned, or if the situation in the Middle East eases rapidly, the risk of an oil price pullback will rise significantly. Additionally, the long-term trend of global clean energy transition still poses a constraint on fossil fuel demand, but at least in the current stage, investors are more focused on the earnings elasticity brought by short-term supply-demand mismatches.

Market Outlook: Energy Stock Rally Far From Over But Volatility Increases

Looking ahead to next week, the trend of the energy sector will depend on multiple factors: first, whether geopolitical events will further ferment; second, whether remarks from Fed officials will show stronger vigilance regarding inflation; third, whether the non-farm payroll data released next week can continue to show resilience.

  • Positive Factors: Expectations of delayed OPEC+ production increases, larger-than-expected decline in global inventories, and the trend of capital returning to the energy sector.
  • Risk Factors: Rapid easing of geopolitical tensions, significantly weaker economic data dragging down demand expectations, and crowded speculative longs in crude oil futures triggering profit-taking.

Overall, today's explosion in energy stocks is not accidental, but the result of the resonance of multiple fundamental factors. Against the backdrop of increased volatility in tech stocks, the energy sector, as a representative of low valuation and high dividends, is regaining favor from capital. For investors, chasing highs in the short term requires caution, but from a medium-to-long-term perspective, the allocation value of energy stocks in investment portfolios is becoming increasingly prominent.
