The chairman of NHN Entertainment Corp., a leading local online game operator, has joined the list of South Korea's stock rich, whose stock holdings are worth more than one trillion won ($937 million), data showed Sunday.

Lee Jun-ho, the chief executive of NHN Entertainment, saw the value of his stocks reach 1.63 trillion won as of the end of February, up 12.3 percent from 947.2 billion won at the end of last year, according to Chaebol.com, which tracks the country's family-run conglomerates known as chaebol.

The sharp rise was attributed to a spike in the share value of Naver Corp., the country's biggest portal operator, owned by Lee.

Naver shares rose 12.9 percent to 817,000 won between the end of last year and end of February. The market capitalization of the portal operator came to 26.93 trillion won, placing it fifth in the local equity market.

Lee's entry into the so-called one-trillion-won club brought the number of such people to 17.

Lee Kun-hee, the chairman of Samsung Electronics Co., held on to the No. 1 spot on the list, with his stocks valued at 11.70 trillion won as of the end of February. The figure is down 2.1 percent from the end of last year. (Yonhap)
