Samsung Reasserts Clout as Top Korean Stock on AI Catch-Up Hopes

Samsung Electronics Co. has at least briefly reassumed its place as South Korea’s most important stock, as investors eye chances for it to eventually make up lost ground in advanced memory chips for artificial intelligence.

Its shares are up 10% in July while those of smaller rival SK Hynix Inc. have dropped nearly 8%. Samsung has accounted for more than a third of this month’s gain in Korea’s Kospi, the world’s best-performing major equity index this year.
