What is the KOSPI?

De Nederlandse versie van deze pagina is in voorbereiding. Tot die tijd staat de tekst in het Engels.

The KOSPI is the benchmark stock index that expresses the market capitalization of companies listed on the Korea Exchange's KOSPI market relative to a base date.

It is calculated with the market capitalization on January 4, 1980 set at 100; originally called the Composite Stock Price Index, it has been called the KOSPI since November 2005. When the number of listed shares changes through paid-in or bonus capital increases, mergers and the like, the base market capitalization is adjusted to keep the index continuous.
