KOSPI, Korea Composite Stock Price Index, is a representative market index of the Korea Exchange (KRX) that tracks the performance of common stocks.

The Korea Composite Stock Price Index (KOSPI) is a comprehensive stock market index that represents the performance of common stocks traded on the Korea Exchange (KRX). Launched in 1983, KOSPI is the primary indicator of the health and trends of South Korea’s stock market.

Overview

KOSPI tracks the value-weighted index of all common shares traded on KRX. It is calculated in real-time and is widely used by investors, analysts, and policymakers to gauge the overall performance of the South Korean equity market. The base value of KOSPI was set at 100 as of January 4, 1980.

Components of KOSPI

Types of Companies Included

The KOSPI index includes a breadth of publicly traded companies across various sectors:

Technology (e.g., Samsung Electronics)
Automotive (e.g., Hyundai Motor Company)
Financials (e.g., KB Financial Group)
Consumer Goods (e.g., LG Electronics)

Selection Criteria

Market Capitalization

Only companies with significant market capitalization that represent substantial economic activities and liquidity are selected.

Trading Volume

Companies must meet minimum trading volume requirements to ensure that they remain relevant and accurately reflect market conditions.

Calculation Method

KOSPI is a market-capitalization-weighted index. It is calculated using the following formula:

\text{KOSPI} = \frac{\sum_{i=1}^{n} (P_i \times Q_i)}{\text{Base Value}} \times 100

Where \( P_i \) is the current price of stock \( i \), \( Q_i \) is the number of shares available, and the base value was set at 100.

Historical Context

The KOSPI index was officially introduced on January 4, 1983, with a base index value set at 100, based on the market value of the issues listed on the exchange on January 4, 1980. Over the years, it has grown significantly, reflecting the economic expansion of South Korea and the dynamic changes within its capital markets.
