Oil's surge did the heavy lifting

Chevron (NYSE:CVX) rose in Friday's session, according to market reports, as one of the clearer winners on the Dow Jones Industrial Average. The catalyst was not company-specific. Instead, the oil major rode a sharp rally in crude that lifted energy producers across the market.

Brent crude, the international benchmark, gained $3.94 to settle at $109.86 a barrel, its highest close since May 19, according to market data. Brent touched $110 during the session, the first time it had reached that level since May. West Texas Intermediate also traded above $101 intraday, though closing quotes varied by contract and source; one quote put the December contract at $99.02, up $2.52.

The driver, according to market commentary, was Iran's escalating attacks on tankers in the Strait of Hormuz, a narrow passage through which a large share of the world's seaborne oil moves, along with threats to Russian refining capacity. ING commodities strategists said oil is "pricing in a significant risk premium."

Energy led the market's rotation

Chevron's gain fit a wider pattern. Energy was the top-performing sector of the S&P 500 on Friday, according to market data, as investors moved money out of technology and into areas seen as more defensive or tied to commodity prices. Utilities, consumer staples, health care, financials and materials also attracted buyers.

Fellow oil major Exxon Mobil (NYSE:XOM) rose as well. A published headline noted that higher refining margins added about $4.5 billion to Exxon's earnings. ConocoPhillips (NYSE:COP) set an intraday record high, while Diamondback Energy (NASDAQ:FANG) jumped to $203.91 and Targa Resources (NYSE:TRGP) climbed to $294.22, per market data.

Geopolitics stayed in the headlines. President Donald Trump, discussing Iran, said: "Now, we're looking at Pickaxe Mountain. We may have to go there." A Saxo Bank analyst pointed to the International Energy Agency's pledge to release the remaining 100 million barrels under its March agreement, a step aimed at easing supply. At the pump, U.S. gasoline averaged $4.33 a gallon, compared with $3.06 a year earlier, market reports showed.

A cushion for the Dow

The energy bid helped the Dow hold up better than other benchmarks. The blue-chip index slipped 175.28 points to 52,002.41, a far smaller decline than the Nasdaq Composite's 572.99-point drop to 26,140.03. The S&P 500 fell 84.62 points to 7,659.44 as a selloff in chip and software shares deepened through the afternoon. The Dow still finished the week higher, while the Nasdaq posted its worst week since June.

Chevron, which explores for, produces and refines oil and natural gas around the world, tends to benefit when crude prices rise because higher prices lift the value of its output. On Friday that dynamic was on full display, with oil-linked names standing out against a sea of red in technology.

Chevron Watches Hormuz and Energy Earnings

Oil traders will keep a close eye on shipping through the Strait of Hormuz and any further developments involving Iran and Russian refining. On the macro front, the Federal Reserve's next rate decision is due October 28, with Fed Chair Kevin Warsh telling an IMF gathering in Bangkok, "I don't prejudge meetings." Energy earnings also begin to arrive: Kinder Morgan (NYSE:KMI) reports October 21, Valero (NYSE:VLO) October 22 and SLB (NYSE:SLB) on October 23 before the open, offering fresh reads on how the sector is handling the price spike.
