Nova, Lattice Semiconductor, IPG Photonics, AMD, and Entegris Shares Plummet, What You Need To Know

What Happened?

A number of stocks fell in the afternoon session after investors reacted to news of Google's new TurboQuant algorithm, a tool that threatens to significantly reduce memory requirements for artificial intelligence models. 

The market's interpretation is that this increased efficiency could lead to a structural decrease in demand for memory chips, sparking a sector-wide sell-off. Sandisk saw its stock fall by as much as 8%. The concerns generated by Google's announcement overshadowed recent strong earnings from memory-makers. 

Adding to the sector's headwinds are reports that competitor SK Hynix is considering a potential $14 billion U.S. listing, which would increase competitive supply pressure in the market.

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

Zooming In On AMD (AMD)

AMD’s shares are extremely volatile and have had 36 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 17 days ago when the stock gained 2.7% on the news that the company announced an expansion of its Ryzen AI Embedded P100 Series processors and signed a multi-year intellectual property license agreement that resolved all outstanding litigation with Adeia Inc. 

The expanded processor lineup was designed for the growing demand in edge AI applications like industrial automation and robotics, delivering up to twice the CPU core counts and up to eight times higher GPU compute. This move signaled AMD's focus on capturing the real-time AI computing market. Separately, the licensing agreement with Adeia Inc. granted AMD access to Adeia's semiconductor intellectual property portfolio, effectively ending a high-stakes patent dispute. The resolution of the ongoing litigation removed a source of uncertainty for the company and its investors, contributing to the stock's rebound.

AMD is down 9% since the beginning of the year, and at $203.32 per share, it is trading 23.1% below its 52-week high of $264.33 from October 2025. Despite the year-to-date decline, investors who bought $1,000 worth of AMD’s shares 5 years ago would now be looking at an investment worth $2,626.
