What Happened?
A number of stocks fell in the afternoon session after the midday Apache helicopter incident over the Strait of Hormuz removed the stable macro backdrop the semiconductor sector needed to extend its recovery.
US Central Command confirmed an American Apache helicopter had gone down near the coast of Oman, and President Trump said the US "must respond" to what he described as an Iranian attack over the Strait of Hormuz. Chips are acutely sensitive to the inflation and rate environment and any development that re-accelerates oil prices keeps the 10-year yield elevated and compresses the high multiples the sector carries. The 10-year was already at 4.53%, and rate-hike probability for year-end already exceeded 50% before this headline.
The underlying concerns from the previous week's rout including Broadcom's cautious AI guidance, a memory chip glut, and the May jobs report pushing yields higher, hadn't resolved. The helicopter incident renewed geopolitical uncertainty just as the bounce was consolidating, pulling the sector back before the CPI reading later in the week.

Zooming In On IPG Photonics (IPGP)
IPG Photonics’s shares are very volatile and have had 25 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 1 day ago when the stock gained 3.7% on the news that the broader semiconductor sector recovered from a sharp selloff during the previous trading session.
The decisive tone-setter was Nvidia CEO Jensen Huang, who described the previous week's selloff as a chance to "buy at a discount," adding that the AI revolution is still "at the beginning." That framing, was enough to stabilize sentiment in a sector that had erased $1 trillion in market cap in a single session.
IPG Photonics is up 42% since the beginning of the year, but at $106.25 per share, it is still trading 31% below its 52-week high of $153.91 from February 2026. Despite the year-to-date gain, investors who bought $1,000 worth of IPG Photonics’s shares 5 years ago would now be looking at only $522.88.
