KOSPI 1983; KOSDAQ 1996· Concept

Korea's main stock index (KOSPI) and its tech-heavy junior market (KOSDAQ), long priced below foreign peers: the 'Korea discount'.
See it on the Money & Finance map →How it works
KOSPI (코스피) began in 1983 with a base of 100 in January 1980 and tracks all main-board stocks; KOSDAQ opened in 1996 for smaller tech and biotech firms. Samsung Electronics and SK Hynix grew to roughly half of KOSPI's value in 2026 as AI demand for memory chips soared. The index went from about 2,400 at the end of 2024 to above 9,000 in June 2026, then plunged, with one-day drops of 8–11% in July.
Why it matters
Korea's market is a high-octane bet on chips and global trade, and its discount shows how governance and shareholder rights affect what investors pay for profits.
Facts, rules and data
Korea Exchange index data, Financial Services Commission policy releases, Korean press such as Yonhap, Financial News and the Korea Herald, and MSCI valuation comparisons.
Debates and risks
Whether governance reforms permanently narrow the Korea discount, or the 2025–26 surge was mostly a memory-chip cycle that could reverse.
Connections (3)
▸KOSPI and KOSDAQ: Korea's stock indexes and the 'Korea discount' surged with Samsung and SK Hynix in The AI stock boom and Big Tech concentrationFact, law or data
The connection
AI servers need high-bandwidth memory (HBM), a market led by SK Hynix, with Samsung catching up. As chip profits soared, the two grew to roughly half of KOSPI's value, and the index rose from about 2,400 at end-2024 to over 9,000 in June 2026 before falling sharply.
When and why
Seoul and Icheon, 2024–26; SK Hynix supplies Nvidia, the leading AI-chip designer.
How we know
KRX market data, company earnings reports, and Korean press coverage of the concentration and the July 2026 selloffs.
Debates and risks
Whether the memory-chip upswing has peaked; analysts disagree on how long AI spending can keep growing.
▸KOSPI and KOSDAQ: Korea's stock indexes and the 'Korea discount' have long traded at a 'discount' on Earnings, market cap and the P/E ratioFact, law or data
The connection
Korean stocks have long traded at lower price-to-earnings and price-to-book ratios than US, Japanese or Taiwanese peers, often near book value. Explanations include chaebol family control, cross-shareholdings, low dividends, North Korea risk and limited currency access. Reforms since 2024 aim to raise payouts and protect minority shareholders.
When and why
Seoul; the term has been common since at least the 2000s, and the government's Value-up program began in February 2024.
How we know
Valuation comparisons from MSCI and brokers; academic studies tie part of the discount to corporate governance.
Debates and risks
How much of the discount reflects governance versus geopolitics or sector mix; experts differ, and the 2026 rally narrowed it.
▸KOSPI and KOSDAQ: Korea's stock indexes and the 'Korea discount' tend to move with The Korean wonMainstream view
The connection
Foreign investors own roughly a third of Korean shares. When they sell, they convert won to dollars, weakening the currency; when they buy, the won tends to strengthen. Both also react to global risk appetite and chip exports, so KOSPI and the won often rise and fall together.
When and why
Seoul's stock and currency markets, with sharp joint drops in 1997, 2008, 2020 and after the December 2024 martial-law crisis.
How solid is the link?
Bank of Korea and KRX data on foreign flows, and studies showing a positive correlation between Korean stocks and the won.
Debates and risks
The link has loosened as Korean individuals buy US stocks, which means selling won even when KOSPI rises.
