What Happened?
A number of stocks fell in the afternoon session after a broader selloff hit the semiconductor sector amid valuation concerns and investor nervousness ahead of Nvidia's earnings report.
The decline was part of an industry-wide trend where investors retreat from richly valued chip stocks. These stocks were a primary force behind the U.S. market's climb to record highs.
Earnings from Nvidia, a key player in the artificial intelligence space, were viewed as a significant test for the AI boom narrative that powered the market. This uncertainty contributed to the negative sentiment across the semiconductor space, leading to a slide in major chipmakers.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Photronics (PLAB)
Photronics’s shares are extremely volatile and have had 38 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 about 21 hours ago when the stock dropped 5.4% on the news that a broad-based sell-off hit the semiconductor sector following news of a potential strike at Samsung and a stake sale by Taiwan Semiconductor Manufacturing (TSMC), which rattled global chip supply chains.
These events highlighted significant supply-chain risks, triggering a sharp reversal across the chip industry. Adding to the sector's weakness were rising valuation concerns, inflation fears, and broader market jitters that led to renewed selling pressure on major companies like NVIDIA, Intel, and Micron Technology.
Furthermore, ongoing supply constraints for rare earth materials, which are used in semiconductor manufacturing, reportedly caused delays and higher input costs for firms in the sector, compounding the negative sentiment for chip-related stocks.
Photronics is up 37.5% since the beginning of the year, but at $45.93 per share, it is still trading 16.4% below its 52-week high of $54.96 from May 2026. Investors who bought $1,000 worth of Photronics’s shares 5 years ago would now be looking at an investment worth $3,506.
