Korean Stock Market Explained: A Guide for Global Investors

Samsung phones, SK hynix memory chips and Hyundai cars connect South Korea’s businesses with customers around the world. The Korean stock market is where investors can buy shares in the companies behind those products.

For international investors, understanding Korean stocks starts with the market itself: how KRX, KOSPI and KOSDAQ fit together, what kinds of businesses are listed there, and how access works depending on where you live.

What is the Korean stock market

The Korean stock market is South Korea’s market for trading shares in publicly listed companies. It is operated by the Korea Exchange, or KRX, which runs three listing markets: KOSPI, KOSDAQ and KONEX.

A share represents an ownership interest in a particular company. An index tracks the performance of a group of shares. That distinction matters when reading headlines about “Korean stocks”: an index rising does not mean every company’s share price has risen.

Key facts

• Exchange operator: Korea Exchange (KRX)
• Listing markets: KOSPI, KOSDAQ and KONEX
• Trading currency: South Korean won (KRW)
• Main benchmark: Korea Composite Stock Price Index (KOSPI)
• Regular session: 9:00 a.m. to 3:30 p.m. Korea Standard Time on trading days

KRX vs KOSPI vs KOSDAQ

These names describe different parts of the market.

KRX is the exchange operator. It runs the markets where companies list their shares and investors trade.

KOSPI is both a market name and an index name. The KOSPI market is the main board, home to established companies including Samsung Electronics and Hyundai Motor. The KOSPI index measures the performance of that market and is weighted by market capitalization, so larger companies have more influence on its movements.

KOSDAQ is a separate market within KRX. It was established to help smaller and growing businesses raise capital, including companies in technology, biotechnology and cultural industries. It also has its own benchmark index.

KONEX serves earlier-stage businesses. It provides another route for small and medium-sized companies to raise equity capital.

For a first look at Korean equities, KOSPI and KOSDAQ are the most useful starting points. A company’s listing market gives context, but does not tell you whether its shares are attractively priced.

Major Korean stocks: Samsung, SK hynix and Hyundai

Three familiar businesses show how different the exposures within one country can be.

Together, these examples show why “Korean stocks” is too broad to describe a single investment idea. Buying a memory chipmaker and buying an automaker creates different exposures, even when both shares trade in the same market. 

Why international investors follow Korean stocks

Korean stocks offer exposure to both global consumer brands and the suppliers behind them. AI infrastructure is one example of why these companies matter beyond Korea: running AI systems requires memory and storage as well as processors, and Korean chipmakers supply a large share of that memory. For investors, this provides another way to participate in the businesses supporting AI development.

Valuation and shareholder returns are another area of interest. Korean shares have historically traded at lower valuations than international counterparts, a pattern commonly called the “Korea discount.” Introduced in 2024, the Corporate Value-up Program encourages listed companies to voluntarily develop and disclose plans to improve corporate value and shareholder returns. For investors, the question is how those plans translate into practical changes: more effective use of capital, better communication with shareholders, and improvements in dividends, share buybacks and governance. Lower valuations alone do not establish that a stock is undervalued; the company’s profitability and growth prospects still matter.

International exposure also requires looking beyond a company’s headquarters. A Korean listing does not mean a business earns all its revenue in Korea, or that its share price will move independently of global markets. Its customers, competitors and production network matter.

Can foreigners invest in Korean stocks

Yes. Foreign investors can invest in Korean-listed securities, although the available route depends on their country of residence, broker and the particular security.

South Korea abolished its foreign investor registration requirement on December 14, 2023. Foreign individuals can now open investment accounts using their passport number, without first obtaining an Investment Registration Certificate. This removes a regulatory step, but investors still need to meet their broker’s account-opening and identity-verification requirements.

How to invest in Korean stocks from abroad

There are three main routes:

• Korean-listed shares: buy a company’s shares through a broker that supports the relevant Korean market and accepts investors from your jurisdiction.
• Depositary receipts: where available, buy a security representing underlying shares through another market. Samsung Electronics, for example, has global depositary receipts listed in London.
• Korea-focused funds: buy shares in a fund that holds Korean equities. The iShares MSCI South Korea ETF, for example, tracks an index of South Korean shares.

These routes differ in what you hold, trading hours, fees and market access. Owning a fund share is not the same as holding an individual company’s shares. Backpack and SK Securities plan to bring Korean stock trading to eligible non-resident foreign investors.

What to understand before investing

Currency exposure

Korean-listed shares trade in won. If you measure your portfolio in another currency, exchange-rate changes can increase or reduce your return when converted back. A stock can rise in won while producing a smaller gain, or even a loss, in your home currency.

Trading hours

The KRX regular session runs during Korean business hours, UTC+9, which falls overnight for investors in Europe and the Americas. Holidays and special schedules can change availability.

Some Korean shares also trade through Nextrade, an alternative trading system with extended hours. Your broker’s supported venues determine which sessions you can use.

Business and portfolio concentration

Several holdings can still depend on the same underlying driver. A portfolio of memory chip companies, for example, may remain sensitive to the same changes in chip demand and pricing. With a country ETF, check its holdings and weights to understand where the exposure is concentrated.

Costs and shareholder rights

Compare brokerage commissions, currency conversion charges, applicable taxes and any fund or depositary fees. Check how the particular security handles dividends, voting and corporate actions, since these differ between direct shares, depositary receipts and funds.

Backpack and SK Securities

On October 29, 2026, Backpack and SK Securities announced a strategic partnership to expand international access to Korean equities. The initial focus is Korean-listed equities for eligible non-resident foreign investors, with broader collaboration across traditional and tokenized financial markets also planned.

The partnership is at the announcement stage and the Korean stock trading service has not launched.
