BlockBeats News, July 15th. Just three days after SK Hynix's ADR listing, the premium over its Korean-listed stock has surged by over 50%. On Tuesday, Hynix's ADR closed with a staggering 27.29% gain, following a record sell-off in the Korean stock market the day before, which caused a sharp drop of over 9% during U.S. trading hours. Currently, its ADR premium has risen to about 51.5%, far above the 3% spread set at the time of issuance last week.

According to a document from the U.S. Securities and Exchange Commission, each SK Hynix ADR is equivalent to one-tenth of a common share. Tuesday's rebound coincided with the start of SK Hynix ADR options trading on U.S. options exchanges, making it easier for the world's largest derivatives market participants to trade this company.

SK Hynix closed at 1,913,000 Korean won (approximately $1284) on Tuesday in Korea, while its ADR price closed at $193.92. With each SK Hynix ADR representing one-tenth of a common share, the price of $193.92 is 51.5% higher than $128 (one-tenth of $1284).
