Not Everything Is Rallying After the US-Iran Ceasefire Deal. These Stocks Are Sliding.

A two-week U.S.–Iran ceasefire deal sparked a relief rally in major indexes, but pockets of the market—particularly oil and related chemical/fertilizer names—declined. Traders priced in eased supply risks from a potential reopening of the Strait of Hormuz, sending U.S. crude down roughly 15% to about $96.53 and Brent down about 13% to $94.75. Major oil producers (e.g., APA, Exxon, ConocoPhillips, Marathon, Occidental) slid—some by ~5–10%—while Chevron fell several percent. Chemical and fertilizer producers like Dow, LyondellBasell and CF Industries also pulled back after earlier gains tied to higher energy-driven cost advantages. Net effect: broad-market strength (S&P 500 up) alongside sector-specific weakness driven by a sharp drop in oil prices, creating a mixed market tone for investors.
