KOSPI is a broad stock index for companies listed on the Korea Exchange's main market. Market-cap weighting gives larger businesses more influence, making it a common gauge of Korean equities.
History and development
KOSPI was introduced in 1983 as Korea's broad, capitalization-based stock-market index, succeeding an earlier index framework. KOSPI 200, launched in 1994, is a separate selection of 200 companies. Their histories differ in both starting date and investment universe.

Comparing charts on this board
Place KOSPI beside TAIEX and the US semiconductor index to examine the international electronics cycle. Joint Korean and Taiwanese strength directs attention to the regional group; divergence directs attention to country-level companies and policy.
KOSPI 200 CFD adds an after-hours perspective. KOSPI is broader than the CFD's 200-company reference, so compare direction by session rather than treating them as identical cash and after-hours series.
