ConocoPhillipsUS-Iran accord ends war and reopens Strait of Hormuz, reducing supply disruption risk premium that had supported ConocoPhillips.

ConocoPhillips shares fell after an agreement was reached to end the war between the US and Iran and reopen the Strait of Hormuz, according to Diamond Hill Capital's Large Cap Strategy second-quarter 2026 investor letter. The exploration and production company detracted from the strategy's performance, which returned 3.42% net of fees, trailing the Russell 1000 Value Index's 13.87% gain. The market increasingly viewed the risk of a meaningful supply disruption as diminished, causing the war-related risk premium that had supported US exploration and production companies earlier in the year to largely dissipate. ConocoPhillips closed at $120.48 per share on July 31, 2026, with a market capitalization of $146.78 billion, and posted a one-month return of 14.52% while gaining 27.75% over the past 52 weeks.
