JK Shin, president and head of Samsung's IT

South Korea's largest conglomerate Samsung Group's IT affiliates lost nearly 20 trillion won (US$19.6 billion) from falls in their share prices since July, data showed Thursday, amid worries that the lagging performance of the group's mainstay unit, Samsung Electronics Co., may continue this year.
The combined market capitalization of Samsung Group's four listed IT firms totaled 214 trillion won as of Wednesday, down 8.4 percent from 233.7 trillion won registered on July 1, according to the data compiled by market researcher FnGuide. The four IT affiliates include Samsung Electronics, Samsung Electro-Mechanics Co., Samsung SDI Co. and Samsung Techwin Co.
