KOSPI 200

KOSPI 200 is a stock market index comprising 200 of the largest and most liquid companies listed on the Korea Exchange (KRX). Introduced on 3 January 1994 with a base date of 3 January 1990 and a base value of 100 points, the index serves as one of the principal benchmarks of the South Korean equity market. The KOSPI 200 is calculated using a free-float market capitalization-weighted methodology and represents a substantial proportion of the total market capitalization of the KOSPI market. Administered by the Korea Exchange, the index is widely used as a benchmark for investment funds, exchange-traded funds (ETFs), derivatives, and portfolio performance measurement, and serves as the underlying index for South Korea's principal stock index futures and options markets.

History

The KOSPI 200 was introduced by the Korea Exchange on 3 January 1994 to provide a representative benchmark for the South Korean equity market and to support the development of derivatives trading.

The index uses a base date of 3 January 1990 with an initial value of 100 points. Following its introduction, the KOSPI 200 became the underlying benchmark for stock index futures and options traded in South Korea, contributing significantly to the expansion of the country's derivatives market.

Over time, the index has become one of Asia's most widely followed equity benchmarks and is used extensively by domestic and international investors seeking exposure to the South Korean economy.

Methodology

The KOSPI 200 is calculated using a free-float market capitalization-weighted index methodology.

Under this approach:

constituent companies are weighted according to their free-float market capitalization;
only shares available for public trading are included in the weighting calculation;
strategic holdings by governments, founders, and controlling shareholders are generally excluded;
constituent weights change automatically as market capitalizations fluctuate.

The methodology is intended to reflect the investable portion of the South Korean equity market.

Composition

The KOSPI 200 consists of 200 companies listed on the KOSPI market of the Korea Exchange.

Constituents are selected according to criteria including:

market capitalization
trading liquidity
sector representation
listing history
investability

The index includes companies from a broad range of industries, including:

information technology
semiconductors
automobiles
financial services
chemicals
pharmaceuticals
healthcare
telecommunications
consumer goods
industrial manufacturing
shipbuilding
energy

Collectively, the constituent companies account for a significant majority of the market capitalization of the KOSPI market.

Calculation

The value of the KOSPI 200 is determined by aggregating the free-float-adjusted market capitalization of all constituent companies.

The calculation involves:

determining each constituent's free-float market capitalization;
aggregating constituent values;
dividing the total by an index divisor.

The divisor is adjusted periodically to maintain continuity following:

stock splits
bonus issues
rights issues
mergers
acquisitions
spin-offs
constituent changes

These adjustments ensure that corporate actions do not artificially affect the index level.

Governance

The KOSPI 200 is administered by the Korea Exchange, which establishes the methodology, reviews constituent eligibility, and maintains the index.

Periodic reviews consider factors including:

market capitalization
liquidity
free-float availability
trading activity
sector balance

Changes to the composition of the index are announced in accordance with the exchange's published review schedule.

The KOSPI 200 forms part of a broader family of indices maintained by the Korea Exchange.

While the KOSPI measures the performance of the broader KOSPI market, the KOSPI 200 focuses on a selected group of large and liquid companies suitable for benchmark and derivatives purposes.

Its principal applications include:

measuring South Korean equity market performance
benchmarking investment portfolios
index funds
exchange-traded funds
futures trading
options trading
passive investment

The index is also widely used as the underlying benchmark for South Korea's stock index derivatives market.

Impact

The KOSPI 200 is one of the principal indicators of the South Korean stock market and is widely regarded as a benchmark for the country's large-cap equity sector. Because its constituent companies represent a substantial share of the market capitalization of the KOSPI market, the index is closely monitored by investors, policymakers, economists, and financial institutions. It plays a significant role in portfolio management, derivatives trading, passive investment, and capital market analysis, and serves as an important measure of investor sentiment toward the South Korean economy.
