SK hynix on Monday surpassed Samsung Electronics in market capitalization, to become Korea's most valuable listed company.
Shares of SK hynix closed 5.61 percent higher, lifting the company's market capitalization to 2,080.37 trillion won ($1,350.98 billion), compared with Samsung Electronics' 2,066.66 trillion won after its stock slipped 0.14 percent.
The milestone marked the first time Samsung Electronics has relinquished the top spot on the benchmark Korea Composite Stock Price Index (KOSPI) since it began its uninterrupted reign in 2000.
Samsung first became the country's most valuable company by market capitalization in 1999.
