Global index provider MSCI has added Samsung SDS Co., a key IT unit of Samsung Group, and three other Korean stocks to its emerging market index in its latest quarterly review, which will take effect later this month, according to its website Wednesday.

The U.S.-based provider of investment research and indices included Samsung SDS, which was listed on the Seoul bourse Friday, immediately becoming the nation’s sixth-largest company by market capitalization.

MSCI also added Daum Kakao Corp., CJ Korea Express Corp. and KEPCO Plant Service & Engineer Co., while deleting Samsung Techwin Co., the defense arm of Samsung Group, to raise the total number of constituents to 106. It will take effect Nov. 26.

Daum Kakao Corp., the merged entity of South Korea’s popular web portal and mobile messaging app, was listed on the tech-heavy KOSDAQ on Oct. 14.

CJ Korea Express is CJ Group’s logistics unit and KEPCO Plant Service is the state-power provider’s construction and engineering unit, which are both listed on the main bourse. (Yonhap)
