A new survey shows that more than 40 percent of the top 100 slots in the South Korean stock markets have changed hands over the past decade.
 
CEO Score, a corporate performance tracker, said Wednesday that 41 KOSPI- or secondary KOSDAQ-listed companies that were among the top 100 in terms of market capitalization at the end of 2005 were no longer on the list as of October 30.
 
Eleven companies that slipped from the list were traditional export industries, such as information technology, electricity and electronics as well as shipbuilding and construction. 
 
Among the 41 companies moving into the top spots, 15 were in domestic-oriented industries, such as food manufacturing, service and distribution.
 
Twenty four of the newcomers, including Samsung C&T and AmorePacific, become top 100 in terms of market capitalization after their initial public offerings, while 17, including LG Household & Health Care and Celltrion, made the list after performance improved.
 
Twenty seven companies, including HHIC Holdings and DSME, have fallen off the list due to faltering stock prices, while 14 other companies have been removed either due to delisting or merger.
 
Five of the top 10 companies have maintained their positions for 10 years, including Samsung Electronics at number one, KEPCO at number three and SK Hynix at number seven.
