Comfort Systems, Quanta, and Rivian Shares Are Soaring, What You Need To Know

What Happened?

A number of stocks jumped in the afternoon session after Trump's Iran peace signal offered more credible prospect of ending a three-month supply-chain disruption that squeezed manufacturers, logistics companies, and commodity processors since the Strait of Hormuz effectively closed in late February.

Cyclical stocks led the broader rally, with the VIX falling 12.5% to 19.44, a sign that investors were broadly repricing geopolitical risk lower. The Strait handles roughly 20% of global seaborne oil; its closure forced rerouting at significant cost while elevating energy-input costs for industrial producers.

Lower oil, WTI at $87.71 from a wartime peak near $100, directly reduces operating costs across manufacturing, chemicals, and transportation. The rate hike probability falling from 51% to 36% additionally improved the financing environment for capital-intensive industrials that have deferred investment decisions.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Rivian (RIVN)

Rivian’s shares are extremely volatile and have had 36 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 4 days ago when the stock gained 6.1% as industrial stocks recovered, carried by the broad market rebound and a read-through from AI-driven capital expenditure commitments. 

AMD announced a £2 billion ($2.66 billion) five-year investment in the UK for AI research and infrastructure, a signal that data-centre construction and the equipment, logistics, and grid infrastructure supporting it continues to draw major capital. Easing Middle East tensions reinforced the sector's recovery. Iran signaled its initial wave of strikes was complete and President Trump called for an immediate ceasefire, pulling energy prices back from levels that would have raised input costs across manufacturing and freight.

Rivian is down 13.9% since the beginning of the year, and at $16.71 per share, it is trading 25.6% below its 52-week high of $22.45 from December 2025. Investors who bought $1,000 worth of Rivian’s shares at the IPO in November 2021 would now be looking at an investment worth $165.84.
