Micron and Western Digital Shares Skyrocket, What You Need To Know

A number of stocks jumped in the afternoon session after investors shrugged off interest rate hike expectations following the August jobs report and unwound defensive positioning in beaten-down chip designers, according to Bloomberg. The U.S. Bureau of Labor Statistics reported that employers added 162,000 nonfarm payroll jobs in August, easily beating estimates of a 56,000 increase from economists polled by FactSet. The agency also reported that the national unemployment rate held steady at 4.1%.The strong labor data initially raised expectations for further monetary tightening, but odds of a September quarter-point interest rate hike settled at a coin-toss 50%, according to federal funds futures data reported by Bloomberg. Typically, higher interest rates place downward pressure on high-growth technology equities by discounting future projected cash flows.Despite these macroeconomic concerns, traders rotated back into the chip sector. During the regular session, KLA Corporation rose 7.98% and Semtech climbed 7.96%, while Marvell Technology advanced 5.92% and Advanced Micro Devices gained 4.18%, according to stock market quote data.

Micron's shares are extremely volatile and have had 68 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 11 days ago when the stock dropped 5.5% on the news that investors trimmed chip exposure to reduce portfolio risk ahead of Nvidia's highly anticipated earnings report. Semiconductor shares experienced widespread selling pressure as traders locked in profits ahead of Nvidia's second-quarter fiscal 2027 financial release. As the dominant player in artificial intelligence processors, Nvidia's earnings and forward guidance set the standard for the broader technology hardware industry. Major chipmakers, including Intel, Advanced Micro Devices, and Taiwan Semiconductor Manufacturing Company, recorded declines ranging from 3% to 5%. Market participants frequently de-risk into high-variance catalysts, especially following significant year-to-date gains in large-cap semiconductor stocks. Caution was further compounded by reports from Bloomberg of potential price increases exceeding 15% on servers equipped with AI chips, prompting investors to adopt a defensive stance across the supply chain.
