MW 15 stocks in the S&P 500 showing double-digit gains since the attack on Iran began
By Philip van Doorn
The materials sector of the S&P 500 has been the strongest of the index's 11 sectors since Feb. 27
Even in the midst of a broad decline for stocks, some winners have emerged since the U.S. and Israel attacked Iran on Feb. 28.
Any bit of good news, or at least an easing of disruption, can change a stock-market trend. But even with some signs of life for stock prices early Friday, 80% of stocks in the S&P 500 were down since the close on Feb. 27 - the day before the U.S. and Israel attacked Iran.
From the close on Feb. 27, the S&P 500 SPX was down 2.6% early on Friday, even as it was up 0.5% that morning. Nine of the 11 sectors of the S&P 500 were down from Feb. 27. The two exceptions were the energy sector, which was up 2.7% during the nearly two-week period, and the information-technology sector, which was up 0.4%. All price changes in this article exclude dividends.
Included in MarketWatch's live coverage of Friday's developments was a report in the Financial Times that France and Italy were negotiating with the government of Iran for safe passage for their ships through the Strait of Hormuz. That helped push the price of front-month contracts for West Texas Intermediate crude oil (CL00) on the New York Mercantile Exchange down 1.2% to $94.52 a barrel. But WTI was still up 41% from the settlement price of $67.02 on Feb. 27.
