Shares of SK Hynix Inc surged over 9% following the announcement of mass production of its advanced high-bandwidth memory (HBM) chip, HBM3E, which features 12 layers and offers 50% more capacity than its predecessor. This development positions SK Hynix favorably in the competitive AI chip market, particularly as it supplies key players like Nvidia. Micron Technology's optimistic forecast for the AI sector further fueled investor confidence, leading to a significant uptick in shares across the semiconductor industry. Despite past fluctuations in stock value, analysts predict continued growth for SK Hynix. The competition in the HBM market intensifies as both Samsung and Micron also prepare to release their advanced versions of HBM chips. SK Hynix aims to deliver these advanced chips by the end of the year, reinforcing its dominance in AI memory technology.
