Chairman Chey Tae-won will not swing a hammer or pull a rope in New York on Friday morning. He is expected to press a touchscreen. At 9:30 a.m. Eastern time, or 10:30 p.m. in Seoul, the gesture will mark the Nasdaq debut of SK hynix’s American depositary receipts, giving US investors a direct dollar-traded route into the South Korean memory chipmaker. SK hynix announced it has set the ADR price at $149 per share, with 177.9 million shares on offer. The offering is expected to generate about $26.
