David Morrison, a senior market analyst at Trade Nation, pointed to steep losses in Samsung and SK Hynix recently. SK Hynix's Korean shares are down 47% from their highs, while Samsung has dropped 38% from its peak. Neither stock is showing signs of a "significant rebound," he wrote in a note on Tuesday. "There's an element of panic creeping in now," Morrison wrote. "Investors are exhibiting a lot of nervousness ahead of earnings reports https://www.businessinsider.com/stock-market-outlook-this-week-fed-meeting-big-tech-earnings-2026-7 from the major hyperscalers." Microsoft, Meta, and Amazon will report second-quarter results this week, which has investors laser-focused on the AI narrative and whether firms will continue to double down on capex spending https://www.businessinsider.com/hyperscalers-cant-win-with-investors-ai-spending-capex-alphabet-earnings-2026-7 . Economist David Rosenberg said the sell-off is rooted in concerns about Chinese competition in the AI race https://www.businessinsider.com/satya-nadella-trust-us-ai-tech-ecosystem-chinese-models-2026-7 , something most investors weren't thinking about a month ago, he wrote this week. JPMorgan's markets intelligence desk also said fears about Chinese competition are among the main drivers of the recent volatility. Additionally, the bank pointed to the rotation going on in the the stock market as investors lean towards value stocks, as well as concerns related to the circular financing of AI. Investors also have "skepticism" about recent deals in the sector, such as Sandisk's partnership with Meta. "I think people are just afraid/just want to sell tech/looking for excuses," Joshua Meyers, an executive director at JPMorgan, wrote in a note on Monday as the sell-off in Asia picked up steam. "Importantly, none of this seems fundamentally driven."
