Samsung Shares Lag SK Hynix’s Rally as Analysts Cite Strike Risk

Samsung Electronics Co. shares’ recent underperformance against SK Hynix Inc. may intensify as a looming workers’ strike weighs on South Korea’s most valuable company versus its rival chipmaker.

Samsung’s shares gained as much as 4.8% to a record high on Monday, part of a global rally driven by continued investor optimism about artificial intelligence. That is overshadowed by SK Hynix’s 12% surge.
