General information only, not investment, legal or tax advice. Rules change: check the official sources linked here and your broker before you act.
KOSPI: the main market
KOSPI (Korea Composite Stock Price Index) is both the main board and its headline index, which started at 100 on 4 January 1980. It holds Korea's largest companies, such as Samsung Electronics, SK hynix, Hyundai Motor and the big banks. The KOSPI 200 index of 200 large companies is the basis for most Korean index futures, options and funds.
KOSDAQ: growth and technology
KOSDAQ opened in 1996 for younger and smaller growth companies: biotech, battery materials, games, entertainment and software, among others. Its listing rules are lighter, and its shares tend to swing more. Successful KOSDAQ companies sometimes move to KOSPI.
KONEX: small and early-stage companies
KONEX opened in 2013 for small and medium-sized companies too early for KOSDAQ. Trading is thin, disclosure rules are lighter and individual investors face extra conditions. JONBUR doesn't write automatic research on KONEX companies.
Same rules for trading
All three trade during the same hours, settle in two business days and (for KOSPI and KOSDAQ) share the same ±30% daily price limit and tick sizes.
