What Happened?
A number of stocks fell in the afternoon session after President Trump declared the Iran ceasefire "over" and threatened fresh strikes, sending crude sharply higher and bond yields up in a broad inflation-driven selloff.
Building materials producers (the makers of aggregates, cement, concrete, and asphalt) are exposed to the shock. On the demand side, their volumes are closely tied to construction activity; the surge in the 10-year yield threatens to push mortgage rates higher, raising borrowing costs for large infrastructure projects.
On the cost side, their exposure to crude is unusually direct: cement and asphalt production are among the most energy-intensive heavy industries, and the end products are incredibly heavy and costly to transport.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Carlisle (CSL)
Carlisle’s shares are not very volatile and have only had 6 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful, although it might not be something that would fundamentally change its perception of the business.
The previous big move we wrote about was 1 day ago when the stock dropped 4.2% on the news that Truist Securities lowered its price target on the stock due to concerns about rising costs and supply chain issues.
The analyst firm reduced its target to $340 from $360, maintaining a 'Hold' rating. The decision was based on significant cost inflation within the commercial roofing industry, driven by higher petrochemical prices and supply disruptions for MDI, a key raw material.
Although Carlisle and its competitors have raised prices to offset these pressures, Truist expects these price increases to lag behind the rising costs. This delay is anticipated to squeeze the company's profit margins through the remainder of 2026.
Carlisle is flat since the beginning of the year, and at $331.60 per share, it is trading 23.8% below its 52-week high of $435.11 from July 2025. Investors who bought $1,000 worth of Carlisle’s shares 5 years ago would now be looking at an investment worth $1,732.
