US Investors Boost SK Hynix ADRs During Korea Holiday

SK Hynix's U.S.-listed ADRs jumped in early trading after a 14% drop the prior session, aided by Korea’s market holiday that kept the underlying stock closed and encouraged U.S. bargain-hunting. ADRs traded at roughly a 27% premium to the Seoul shares, reflecting the size of the U.S. investor base, and Barron’s notes the stock’s forward P/E is low relative to Micron, offering a cheaper way to play the memory-chip upcycle.
