Woofun AI reports that SK Hynix and Samsung Electronics shares declined by 12% and 8.8% on Thursday, following the imposition of restrictions on leveraged funds tracking chip manufacturers by South Korean authorities. SK Group Chairman Chey Tae-won stated at a Korea Chamber of Commerce and Industry forum that memory chip demand is growing exponentially, which he believes supports a long-term upward trend for the stocks despite recent corrections after excessive gains.
