What Happened?
A number of stocks jumped in the afternoon session after WTI oil fell 4.7% and Treasury yields declined on Iran-US peace progress.
Construction and maintenance companies (MasTec, Quanta Services, MYR Group, EMCOR, Comfort Systems) execute the long-cycle infrastructure projects: power transmission, data center buildouts, electrical and mechanical work that underpin both the traditional economy and the AI infrastructure trade.
These companies operate on multi-year contracted backlogs that they convert to revenue as projects ship. Lower oil reduces their fuel costs (heavy equipment, transportation, hot mix asphalt for paving), while lower yields reduce financing costs for their customers (utilities, data center operators, REITs). The AI infrastructure buildout adds a third tailwind as companies like Quanta and MYR are heavily exposed to the electrical grid expansion that AI data centers demand.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Primoris (PRIM)
Primoris’s shares are very volatile and have had 23 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 12 days ago when the stock gained 3.5% on the news that the Dow Jones Industrial Average retook the 50,000 level, driven by 'remarkably strong' corporate fundamentals and a breakthrough in U.S.-China relations.
President Trump and President Xi agreed in Beijing to ensure the Strait of Hormuz remains open, a critical win for global manufacturing supply chains choked by Middle East conflict. Also, April retail sales rose 0.5%, matching estimates and signaling that demand for industrial-produced goods remains stable. Industrial companies build the machinery and infrastructure that power the global economy.
While the 1.9% jump in import prices reported confirmed that manufacturing inputs were still more expensive, the reduction in geopolitical risk and the easing of the 10-year yield to 4.46% lowered the cost of the long-term debt used to finance these massive industrial projects.
Primoris is down 2% since the beginning of the year, and at $128.04 per share, it is trading 36.9% below its 52-week high of $202.92 from May 2026. Despite the year-to-date decline, investors who bought $1,000 worth of Primoris’s shares 5 years ago would now be looking at an investment worth $4,160.
