MACOM, Seagate, and Entegris Stocks Trade Down, What You Need To Know

What Happened?

A number of stocks fell in the morning session after the 30-year U.S. Treasury yield hit a 19-year high and oil stayed elevated as a window for a U.S.–Iran deal closed without a breakthrough, a CNBC report revealed. 

Deutsche Bank’s Jim Reid wrote in a note (reported by CNBC) that “with little sign of a U.S.–Iran deal, investors priced in a more extended closure of the Strait of Hormuz and a longer stretch of higher oil.” That is a problem for chip stocks twice over: it lifts the discount rate applied to future earnings, and it raises the cost of financing the same data-center buildout those earnings depend on. Carl Weinberg, founder of High Frequency Economics, told CNBC’s “Squawk Box Europe” that AI infrastructure borrowing is competing with governments for the same pool of savings and helping push bond yields higher, a loop that then feeds back into lower chip valuations.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On MACOM (MTSI)

MACOM’s shares are extremely volatile and have had 34 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 gained 3% on the news that Benchmark reinstated coverage of the stock with a Buy rating and a $375 price target, as reported by TipRanks. 

According to a research note from Benchmark, about two-thirds of Macom’s revenue is tied to markets with structurally higher growth rates. The firm also sees Macom benefitting from favorable cyclical trends that are broadening across the semiconductor market. 

Contributing to the momentum, Anthropic told prospective investors its second-quarter revenue jumped more than 14-fold, according to Bloomberg, with preliminary revenue of more than $11.5 billion versus $4.73 billion in the first quarter. That sequential doubling, and a move into positive adjusted operating income, could be evidence AI labs can keep funding chip spend.

MACOM is up 70% since the beginning of the year, but at $297.49 per share, it is still trading 27.4% below its 52-week high of $409.68 from May 2026. Investors who bought $1,000 worth of MACOM’s shares 5 years ago would now be looking at an investment worth $5,216.
