The KOSPI 200 is the South Korean index, indicative of the top 200 stocks in the Korea Exchange. It maps over 70% of the total capitalization of the exchange and is the most liquid index for the South korean market. The KOSPI 200 was started on January 3rd, 1990 with a base value of 100[1]. The Futures and Options markets in Korea use this index to base their calculations. KOSPI 200 is updated every 2 seconds and is published by the statistical KRX publication of the Korean Exchange[2]
Weighting and Calculations
The KOSPI is calculated as follows with Current Market Capitalization (=market capitalization at the time of comparison) as the numerator and Base Market Capitalization (=market capitalization as of January 4, 1980) as the denominator.
That is:
Current index = Current total market cap of constituents × 100 / Base Market Capitalization[3]
The base market capitalization is adjusted when there is a change in the value due to rights offering, new listing, delisting, mergers, etc.
So the New Base Market Capitalization would be[4]:
Past Market Capitalization*(Current Market Cap +- change in market cap)/Current Market Cap on the day before the change.
