SK hynix's US ADS trades at a persistent premium to its Seoul shares, so US buyers are overpaying for the same company. At today's won rate, the Seoul shares behind one ADS are worth $130.47 while the ADS trades at $186.76, a 43.1% premium. In 53 sessions since the 10 July listing the premium has never fallen below 14.8%, holding between 29% and 47% since mid-August. Arbitrage is limited because the prospectus says depositing shares for ADSs may be restricted by US and Korean law. x.com x.com x.com
