Samsung’s Best Day Since 2008 Powers South Korean Stock Rally

A global rush to secure memory chips for artificial intelligence is powering a renewed surge in South Korean equities, with chipmakers leading a rebound that pushed the Kospi to a fresh record on Tuesday.

Samsung Electronics Co shares jumped 11% on Korea Exchange, the most since 2008, while SK Hynix Inc. added more than 9%. Both stocks recouped losses from the previous session. The benchmark Kospi climbed nearly 7%, extending its gain for the year to 25% and solidifying its status as the world’s best-performing equity index.
