What is the Korean Composite Stock Price Index (KOSPI)?

The Korean Composite Stock Price Index (KOSPI) is a group of indexes that track the stock exchange in South Korea. It was previously named the Korea Stock Exchange. Just as the NASDAQ Composite Index and the S&P 500 Index are representative stock market indexes in the United States, the KOSPI represents the stock market index in South Korea. It follows a wide variety of industries, and it also tracks bonds, options, and futures.

Korean Composite Stock Price Index (KOSPI)

History of the KOSPI

The Korean Composite Stock Price Index was first introduced in 1983 to replace the Korean Composite Stock Price Index (KCSPI). At the beginning of 1983, it was trading at a value of 122.52 points. In November 2020, it has traded above 2300 points. Throughout the years, it experienced drastic changes in its value. The 2008 Global Financial Crisis, the 9/11 terrorist attacks, and the COVID-19 pandemic all heavily impacted the value of the index.

Over the years, the KOSPI also expanded to include various indexes and derivative products. Some of the indexes include KOSPI 200, KODI Dividend Index, and KOGI Corporate Governance Index. There are also industry-specific indexes, such as banks, chemicals, and technology.

Market-Weighted Index

The KOSPI is an index made up of companies based on their market capitalization, which means that it is a market-weighted index (or capitalization-weighted index). It means that any changes to the total market value of all the companies in the stock market index would reflect the same change in the value of the index.

For example, if the total market value of all the companies increased by 10%, then the value of the stock index would also increase by 10%. As a result, many Korean investors use the index as an indicator of how well the stock market in South Korea is performing overall.

Additionally, each stock weighs differently than other stocks depending on its market capitalization. Therefore, a company with a very large market capitalization will receive greater weight, so it will exert a greater effect on the value of the index.

Requirements for Listing

In order for a company to qualify to be part of the KOSPI, there are criteria that companies need to meet. A selection committee chooses a company in terms of requirements, such as its business history, capital size, financial performance, and corporate governance. There are also other considerations as well, which include:

  • Companies must meet a certain level of sales for the three most recent fiscal years.
  • The shareholders’ equity of the business must be at least 10 billion KRW, or the business must achieve a market capitalization of at least 20 billion KRW.
  • Companies must also prove their suitability to be listed, such as demonstrating their corporate stability, meeting requirements for management methods, and proving compliance with accounting regulations.


Among all the indexes in South Korea, one of the most tracked indexes is KOSPI 200. It includes 200 of the largest companies in South Korea as measured by market capitalization, which makes up 70% of all the market value in the KOSPI.

The KOSPI is an important index because it is one of the most active indexes in the world, as it is also listed on futures and options markets. Since it consists of large-cap stocks, many investors look towards the KOSPI 200 index to gauge the overall performance of the stock market in South Korea.

How to Invest in the KOSPI

Investors cannot directly invest in the stock index itself. You may buy and sell stocks that are listed on the index, or you may invest in an exchange-traded fund (ETF) that tracks the performance of the index. Here are a few examples of ETFs:

  • KOSPI 200 ETF (HKOR)
  • Samsung KODEX KOSPI LargeCap ETF
  • Kyobo Axa Power K100 ETF
