Samsung Electronics stock jumped over 7% on Monday following the company’s announcement of a buyback plan. The surge adds to Friday’s more than 7% gain after Samsung reached a preliminary agreement with its largest workers union, which went on strike in July. Shares had recently hit a four-year low amid disappointing third-quarter guidance and U.S. tariff concerns. Samsung faces challenges in the semiconductor market, with analysts noting its lag behind SK Hynix in high-bandwidth memory chips used by Nvidia.
