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 3 days ago when the stock dropped 6.1% on the news that President Donald Trump threatened to impose 'massive' new tariffs on Chinese goods. President Donald Trump's threat of "massive" new tariffs on Chinese goods sent shockwaves through the market, directly impacting chipmakers like Nvidia and AMD. Trump noted China's tightening controls on rare earth metals, which are vital components in many technology products from electric vehicles to defense systems. Compounding the pressure, Beijing has reportedly initiated its own countermeasures. These include tightening export controls on crucial raw materials such as rare earths and launching an antimonopoly investigation into chip giant Qualcomm. Furthermore, reports indicate that Chinese customs officials are now conducting stringent checks on semiconductor shipments arriving at ports, specifically targeting certain high-end chips. This escalating back-and-forth creates significant uncertainty for the semiconductor industry, which relies heavily on complex global supply chains and access to international markets, leading to a broad sell-off across the sector.Teradyne is up 9.9% since the beginning of the year, and at $139.13 per share, it is trading close to its 52-week high of $147.87 from October 2025. Investors who bought $1,000 worth of Teradyne’s shares 5 years ago would now be looking at an investment worth $1,588.
