Thus, changes in the stock prices of large companies, such as Samsung and Hyundai, can greatly affect KOSPI’s performance.
  • There are derivative products linked to the KOSPI, such as futures and options, which allow investors to bet on the future movements of the entire index. This is a very popular type of investment, and the KOSPI 200 options are considered one of the most traded derivatives in the world.

1. Samsung Electronics: This South Korean multinational electronics company is listed on the KOSPI. Its stock price performance directly influences the KOSPI index level because of its significant market capitalization. If Samsung’s stock price rises significantly, the KOSPI is likely to increase too.

2. Stock Market Crash in 2008: During the financial crisis in 2008, the KOSPI experienced a severe decline, mirroring the crash in other global markets. The index fell from over 2,000 points to below 1,150 points within a few months, reflecting the broad sell-off of shares following the bankruptcy of Lehman Brothers and subsequent panic in the world’s financial markets.

3. Tech Boom: South Korea’s stock market, represented by the KOSPI, rose dramatically during the global tech boom of 2020. The increasing demand for Korean tech products, like semiconductors and smartphones, from companies like Samsung and LG showed a significant improving trend of KOSPI over the year, reflecting the growth and innovation in Korea’s tech industries.
