KOSDAQ Series_KOSDAQ Sub-indices for Market Capitalization
As a parameter to be used in analysis of the market and portfolio performance, the KRX-KOSDAQ Market Division produces KOSDAQ sub-indices by grouping the listed stocks on the KOSDAQ market into large-cap, med-cap and Small-cap by the size of their market capitalization.
The KOSDAQ sub-indices for capital size produced in the early stages of the KOSDAQ market, are based on listed capital and do not accurately reflect the latest market change and inconsistent with the stock price index. Considering the fact that most of exchanges in the world classify companies by their market capitalization, the KRX-KOSDAQ Market Division began to produce and publish the market capitalization subindices in July 29, 2002.
Eligible Constituent Stocks
Issues used for calculation are all stocks listed on the KOSDAQ market with the exception of the stocks of the securities investment firms. The initially listed stocks are temporarily excluded until the next regular realignment date.
Classification Standards
Using the average daily market capitalization for the 6 months period retrospective to the regular realignment date, the top 100 stocks in terms of market capitalization are classified as “Large-Cap (KOSDAQ 100)”, 101 to 400 are classified as “Mid-Cap (KOSDAQ MID 300)”, and the rest are classified as “Small-Cap (KOSDAQ Small)”.
Regular/Special Realignment of the Constituents
In order to improve the significance of the indices and ensure that they accurately reflect market conditions, the constituents are realigned twice a year, on the trading days after the days that are the last trading days of March and September contracts in the futures and options markets.
However, when a constituent stock is delisted, such stock is removed from the constituents on that very day.
Publication
KOSDAQ sub-indices by market capitalization is updated on the KRX website every 10 seconds and is available in statistical KRX publication “KRX Review” on a daily, monthly, and yearly basis.
