In South Korea, the main tracking index is the Korean Composite Stock Price Index, or KOSPI for short. Originally started in 1964, the index has been modified numerous times over the years, taking its current form in 1994. The KOSPI Index is comprised of 200 of the largest and most liquid issues traded on the Korean Stock Exchange. The index is market capitalization weighted, meaning that firms with the largest market value have the greatest influence on the KOSPI's returns.
