An escalation in hostilities in the Middle East is weighing on market sentiment, with WTI crude oil (CLQ26) up more than +4% today after the US, over the weekend, launched fresh missile attacks against Iran, targeting Iranian air-defense systems, coastal radar sites, and missile and drone capabilities. Meanwhile, Iran launched retaliatory missile and drone attacks at targets in Jordan, Bahrain, Kuwait, and Qatar. Iran also attacked two vessels attempting to transit the Strait of Hormuz on Sunday.

Stocks extended their losses and crude oil prices added to their gains after President Trump said the US is reinstating the Iranian blockade and stopping Iranian ships from using the Strait of Hormuz. He added that otherwise the strait will remain open "with or without Iran" and that the US would be reimbursed at a rate of 20% of all cargo shipped for providing protection in the area. The outlook for strong Q2 earnings, which will begin this week, is a bullish factor for stocks.

Forecasts compiled by Bloomberg Intelligence suggest Q2 earnings may increase by +23%, close to Q1's blowout earnings of +30%, which was more than double the +12% analysts had expected. AI spending is expected to account for most of earnings, with AI infrastructure stocks set to contribute nearly 60% of the S&P 500's earnings-per-share growth in Q2.
