Shares of companies that benefited the most from the Iran conflict were understandably taking a broad beating in early Wednesday trading, as the cease-fire sent oil and other commodity prices plunging. The Dow Jones Industrial Average DJIA was up 1,266 points, or 2.7%, in early trading, at 47,850.15. The S&P 500 index SPX was up 2.3%, with 73% of component stocks showing gains. All price changes in this article exclude dividends.

Underscoring that action, continuous front-month contracts for West Texas Intermediate crude oil (CL00) were down 18% to $92.60 a barrel on the New York Mercantile Exchange early Wednesday. WTI was still up 61% from $57.43 at the end of 2025, however. Here are the 20 stocks among the S&P 500 showing the largest declines in early trading on Wednesday: Click on the tickers for more about each company. Read: A guide to the information available on the MarketWatch quote page APA (APA) was the S&P 500's biggest decliner, as the oil producer sank 11.8% toward its largest one-day decline in six years, since the height of the COVID-19 pandemic panic. More than half of the stocks showing the largest early declines on Wednesday were in the energy sector, but fertilizer makers were also hit hard. Shares of LyondellBasell Industries (LYB) were down 10.4% early Wednesday. The stock had soared 40% in March as the Iran conflict raged. Oil and gas supply wasn't the only thing getting choked off: The Middle East accounts for up to about 40% of all urea fertilizer exports, a higher percentage than for crude exports from the region. Dow (DOW) was down 9.3% early Wednesday and CF Industries Holdings (CF) was down 9.2%. Both produce agricultural chemicals, and as you can see in the table above, both stocks were still up quite a bit from Feb. 27, the day before the U.S. and Israel launched their attack on Iran. The State Street Energy Select Sector SPDR ETF XLE was down 4.5%, with all 22 of its equity components losing ground. But the exchange-traded fund was still 2.8% above its Feb. 27 close. It was up 29% from the end of 2025. Despite the sigh of relief the cease-fire has provided, "the situation remains fragile," Capital.com senior market analyst Daniela Hathorn wrote in a note to clients. She believes the terms of the cease-fire appear heavily tilted in Iran's favor, which raises questions about whether the deal is politically sustainable for the U.S. "There is also a real risk that talks break down and the conflict reverts to its previous state, or even escalates further, once the cease-fire window expires," Hathorn wrote. "As a result, markets are likely to treat this as a pause rather than a resolution." Among other notable decliners early Wednesday, shares of Occidental Petroleum (OXY) fell 8.5%, ConocoPhillips was down 7% and Exxon Mobil (XOM) declined 6.4%. Among the food and agricultural names on the list of largest decliners, Bunge Global's shares (BG) fell 5.3%. The company benefited as worries that surging fertilizer and oil prices would boost prices for agricultural commodities. The iShares S&P GSCI Commodity Indexed ETF GSG slumped 7.3% in early trading after posting a record 24.2% gain in March. \-Tomi Kilgore -Philip van Doorn This content was created by MarketWatch, which is operated by Dow Jones & Co.
