The Korea Discount Explained: Why Are Korean Stocks Cheap?

Korean stocks have traded at lower valuations than shares in most other major markets since the early 2000s, a gap investors call the "Korea discount." For a foreign investor, it raises the first question about almost any Korean share: is the stock cheap because it is overlooked, or cheap for a reason?

The Korea Capital Market Institute (KCMI), a research body that studies Korea's financial markets, measured the gap in a September 2025 study of 59 stock markets. From 2006 to 2024, Korean listed companies traded at an average of about 1.2 times their book value, compared with 1.9 for developed markets and 1.7 for emerging markets.

The gap narrowed sharply during the 2025–2026 rally. The KOSPI, Korea's main stock index, traded at 2.40 times book value on May 22, 2026, up from 0.88 on May 22, 2025, according to Korea Exchange data cited by the Financial News.

Even then, 523 of 808 KOSPI companies still traded below book value. By Oct. 12, 2026, the index had also fallen 30% from its June 2026 peak, the Korea JoongAng Daily reported.

Here's what you need to know.

What Is the Korea Discount?

The Financial Services Commission (FSC), Korea's financial regulator, describes the Korea discount as "the tendency of Korean stocks to be valued lower than international counterparts." The most common yardstick is the price-to-book ratio (PBR), a company's market value divided by its net assets.

A PBR below 1 means the market values a company at less than its net assets. KCMI studies of different periods all place Korea near the bottom of global rankings.

In a February 2023 paper, KCMI found that from 2012 to 2021, the price-to-book ratios of Korean listed companies ranked 41st out of 45 countries. They were only 52% of the level in advanced economies and 58% of that in emerging markets, and the discount appeared in every sector except health care.

A September 2024 KCMI analysis by Lee Sang Ho compared average ratios in major markets from 2010 to 2022:

In the most recent year of that study, Japan's ratio rose to 1.82, leaving Korea the lowest of the six at 1.54, Lee wrote.

Regulators do not blame a single cause. "The 'Korea discount' is an outcome of multiple factors coming to play in combination," the FSC said in February 2024. For accounts, costs and trading hours, see our guide on how to buy Korean stocks from abroad.

How Do Chaebol Control Companies With Small Stakes?

Chaebol, Korea's family-controlled business groups, sit at the center of most explanations. The Korea Fair Trade Commission (KFTC), the competition regulator, designates the largest groups every year and applies disclosure rules and limits on how their companies own one another.

On April 29, 2026, the KFTC announced 102 designated groups with at least ₩5 trillion in assets, covering 3,538 companies. Companies in the 47 groups with ₩12 trillion or more are barred from cross-shareholdings, in which two group companies own each other, and from creating new circular shareholding chains.

The founding families control these groups with small direct stakes. In the 89 groups controlled by an individual, the family directly held an average of 3.5% of group companies' shares, while affiliates held 55.5%, the KFTC said on Sept. 3, 2026. Including affiliates and other related parties, insiders held 61.4%.

Simply put, a family that owns a few percent of the shares can steer a whole group, because the group's companies own one another. Holding companies are one way to build that chain, and under the rules the KFTC enforces, a holding company must own at least 30% of a listed subsidiary and 50% of an unlisted one.

That gap between ownership and control worries outside investors. The FSC said in June 2026 that companies often issued exchangeable bonds backed by treasury shares, stock they had bought back, to "defend management control or maintain the power of controlling shareholder, which raised the problem of conflict of interests."

KCMI found a similar pattern among the cheapest companies. About 12% of listed firms were "asset-rich firms" in June 2025, meaning their market value was below even the fair value of their net assets, Lee wrote in September 2025. Among those on the KOSPI, 71% had controlling shareholders with more than 50% of voting influence.

Why Do Holding Companies and Duplicate Listings Weigh on Prices?

Duplicate listing, in which a parent company and its subsidiary both trade on the stock market, is a second common complaint. At the end of 2025, separately listed subsidiaries made up 11.2% of Korea's total stock market value, compared with 0.05% in the United States, 4% in Japan and 2.4% in China, the Korea Times reported.

The worry is double counting. Investors have long argued that once a valuable business is listed separately, "part of the parent's value is effectively counted twice in the market," the Korea Times reported. The parent, often a holding company, can then trade below the value of what it owns.

KCMI's research backs the concern. In a June 2022 paper, it found that chain listings of parents and subsidiaries made up 20% of new listings every year. When a split-off subsidiary goes public, parents already listed on the exchange "tend to experience a significant decline in enterprise value," the paper said.

Activist investors measure the result against net asset value (NAV), the market value of a company's holdings minus its debts. Palliser Capital, a London-based activist fund, cited a 74% discount to NAV at LG Chem when it pressed the company on board and buyback reforms in 2025, the Korea Herald reported.

The FSC shares the concern. Its English summary of Chairman Lee Eog-weon's remarks at an April 16, 2026 seminar said ordinary shareholders "were left out from sharing the profit of growth achieved by the subsidiary company and had to bear the cost of discounts in stock prices."

On July 6, 2026, the FSC and the Korea Exchange (KRX) proposed rules under which companies would, in principle, no longer list subsidiaries split off from listed parents, the Korea Times reported. The rules cover companies in which a listed parent owns at least 20%, and the FSC said exemptions would follow strict rules.

Why Are Korean Preferred Shares Cheaper Than Common Shares?

Many Korean companies also list preferred shares, a second class of stock. "Korean preferred shares generally carry similar economic entitlements to common shares but typically lack voting rights," the Korea Herald reported, adding that differences in voting rights, liquidity and investor demand "can contribute to their lower valuations."

Samsung Electronics shows the size of the gap. In prices cited by the Korea Herald on Oct. 14, 2026, Samsung's common shares traded at around ₩237,500 ($177), compared with ₩176,600 for its preferred shares. The dollar figure is the Herald's own conversion.

Palliser put Samsung's discount at 26% and the average for Hyundai Motor's three preferred share classes at about 48%. Its founder and chief investment officer, James Smith, made the case at an investment conference in San Francisco, the Herald reported. "The natural next step to reduce the discount is for boards to address preferred shares explicitly in their Value-Up plans through buybacks, explicit discount targets and other accretive measures," Smith said.

Palliser estimated that the gap represents more than $60 billion in potential value across the Korean market. Samsung said it was "considering ways to address the discount of preferred shares relative to ordinary shares and enhance their value."

The discount is common across the market. Of 114 preferred stocks, 79 traded below their common shares at the close on Sept. 15, 2026, at an average discount of 41.37%, the Asia Business Daily reported. Samsung's preferred stock was 24.71% below its common shares that day, wider than its three-year average of 18%.

What Does Research Say About Why Korean Stocks Are Cheap?

KCMI's February 2023 study tested the usual explanations against company data from 45 countries. It pointed to three problem areas: "low shareholder returns; low profitability and growth potential; and vulnerable corporate governance."

Shareholder returns carried the most weight. In the paper's comparison of factors, they accounted for 37% of the explanatory power, ahead of companies' financial traits at 36% and corporate governance at 7%.

Korea ranks low on that measure. Counting dividends plus buybacks as a share of net income, Korean companies ranked between 27th and 45th of 45 countries in the years studied, and 40th or lower from 2010 to 2018.

North Korea, a frequently suggested cause, did not hold up. Korea ranked about 10th of 43 countries for risk on the Caldera and Iacoviello geopolitical risk index, which swings with events such as North Korean nuclear tests. Yet the paper found "no evidence that geopolitical risks and short-termism in investment affect corporate valuation."

KCMI's September 2025 study framed the problem as returns. The return implied by Korean share prices, a measure of what investors demand, averaged 11.5% a year from 2006 to 2024, against 8.9% in developed markets and 10.9% in emerging markets. Korean stocks delivered about 7.3% a year in total shareholder returns, below 8.4% in developed markets and 13.6% in emerging ones.

The study traced the high required return partly to company policies, including "inefficient deployment of surplus capital, low capital efficiency, and passive payout."

Not every researcher sees mispricing. Lee wrote in September 2024 that "the underlying cause is more likely associated with diminished profitability and insufficient shareholder returns, which result in low but fair valuations." His comparison of six major countries found that Korea's non-financial listed companies "are not undervalued relative to their intrinsic value."

Is the Korea Discount Narrowing?

Policy has gone after the causes directly. On Feb. 26, 2024, the FSC laid out the Corporate Value-up Program, which asks listed companies to disclose plans to raise their value on a voluntary basis, and planned a Korea Value-up Index of "best practice companies."

Lawmakers then rewrote corporate law. On July 3, 2025, the National Assembly passed a Commercial Act revision that extends directors' fiduciary duty beyond the company to its shareholders, the Korea Herald reported. A second revision, passed on Aug. 25, 2025, requires listed companies with assets above ₩2 trillion ($1.4 billion) to adopt cumulative voting, which helps minority shareholders elect a director, the Korea Times reported.

A third revision, passed on Feb. 25, 2026, requires companies to cancel treasury shares within a year of acquiring them, Korea.net reported. Listed companies cancelled ₩43.1 trillion of treasury shares from January to May 2026, more than double the ₩21.4 trillion cancelled in all of 2025, the FSC said.

Prices moved as well. The KOSPI rose 76% in 2025 and another 110% through June 2026, the Korea JoongAng Daily reported. On Feb. 20, 2026, its price-to-book ratio reached 1.87, the highest in 18 years and three months, though still well below the U.S. market's ratio of more than 5, the Financial News reported.

"The revision of the Commercial Act is a signal that Korea is beginning to resolve the 'Korea discount,'" Kim Doo-un, an analyst at Hana Financial Investment, said after the July 2025 vote, according to the Korea Herald. KCMI's Kang Sohyun wrote in January 2026 that the market, "long subject to the so-called 'Korea discount,'" had "entered a structural turning point."

The rally was narrow, however. By early November 2025, the two largest companies made up about one-third of the KOSPI's market value, the highest share since 2010, Kang wrote, after improved earnings at chipmakers such as Samsung Electronics and SK hynix.

Together, the evidence suggests the Korea discount has less to do with North Korea than with how much outside shareholders receive, in payouts and in votes, from companies that founding families control.
