SKHY Premium Calculator / Price gap guide
SK Hynix arbitrage: why does SKHY trade at a premium?
A visible gap between the Nasdaq ADR (SKHY) and Korea-listed 000660 is a theoretical spread, not automatically a risk-free arbitrage opportunity.
Different market hours
Nasdaq and KRX trade in different time zones and close at different times. News can reprice one market while the other is shut, so the displayed premium may temporarily reflect stale or asynchronous quotes.
Conversion and currency risk
One ADR represents one-tenth of a Korean ordinary share. The parity calculation also depends on USD/KRW. FX moves, depositary fees and corporate actions can change the apparent premium even when the underlying company value is unchanged.
Fees, liquidity and short constraints
Transaction costs, bid-ask spreads, taxes, settlement timing and limited borrow can consume a spread. Short-sale rules and different investor access mean the two legs cannot always be executed at the same size or price.
