NEW YORK, Nov. 10, 2026 /PRNewswire/ -- Equity Insider News Commentary - U.S. stocks were lower in late morning trading on Tuesday, the day the Bureau of Labor Statistics published its October Consumer Price Index.

What the inflation report showed

According to the Bureau of Labor Statistics, the Consumer Price Index for All Urban Consumers increased 0.4 percent on a seasonally adjusted basis in October after rising 0.6 percent in September. The index for all items less food and energy rose 0.3 percent in October, as it did in September and August.

The agency said it did not collect survey data for October 2025 because of a lapse in appropriations and, as a result, cannot publish 12-month percent changes for October 2026 for indexes where October 2025 data are unavailable.

Inside the chip: inspection and process control

Onto Innovation Inc. (NYSE: ONTO) was up 1.41% as of 11:42 a.m. ET. In its third quarter 2026 results released November 9, the company reported record quarterly revenue of $410 million, an increase of 88% as compared to the third quarter of 2025, with revenue, operating margin and earnings per share all exceeding the high end of its previously announced non-GAAP guidance ranges. Onto said Advanced Packaging and Specialty Devices also achieved record revenue, primarily driven by the Dragonfly® G5 and Firefly® inspection systems, and it said it expects fourth quarter revenue of $430 million to $450 million.

"Our outstanding results this quarter reflect excellent execution by our team and continued strength in the markets we serve," said Mike Plisinski, chief executive officer of Onto Innovation. "Demand remains robust as increasingly complex device architectures for next-generation AI and high-performance computing drive greater process control requirements."

Moving data with light

Coherent Corp. (NYSE: COHR), which describes itself as a global leader in photonics, was down 3.34% at the same time stamp. Its first quarter fiscal 2027 results, released November 4 for the quarter ended September 30, 2026, showed revenue of $2.37 billion, an increase of 50% year over year and 56% year over year on a pro forma basis, with GAAP net income of $1.90 per diluted share and non-GAAP net income of $2.09 per diluted share. CEO Jim Anderson said the company expects fiscal 2027 pro forma revenue growth to exceed 60%.

"As AI datacenters transition from copper to optical connectivity, Coherent's broad photonics platform and manufacturing scale position us to help customers meet rising needs for bandwidth and energy efficiency," said Jim Anderson, CEO.
