SK Hynix shares plunged nearly 10% in a single trading session. The selloff reduced the company's market capitalization to approximately $943 billion. This decline erased the $1 trillion valuation milestone reached on May 27.
The drop occurred as SK Hynix presented at Computex 2026. The company revealed specifications for its next-generation HBM4E memory. SK Hynix emphasized its alliance with Nvidia to counter competition from Samsung. Intense rivalry in the high-bandwidth memory sector continues to fuel stock volatility.
