Iran conflict lifts 15 S&P 500 stocks into double-digit gains

Despite a broad market dip, 15 S&P 500 components have surged with double-digit gains since Feb. 27 as the Iran attack drags on, led by chemicals and energy names (e.g., CF Industries, LyondellBasell, Dow, Marathon Petroleum) and extending to software and crypto-oriented stocks. The materials sector has been the index’s strongest in this window, highlighting a selective rally amid geopolitical tensions.
