Korean stocks reached historic undervaluation levels as the KOSPI market's 12-month forward price-to-earnings ratio (PER) fell to 5.13x as of May 28, according to securities industry analysis. The valuation represents a 50% decline from the year's high of 10.57x recorded in late January and sits below the 6.82x level seen during the October 2008 financial crisis. The sharp drop reflects a combination of external uncertainties affecting Korean semiconductor exporters and domestic market liquidity pressures, pushing the market into what analysts describe as an unprecedented discount zone relative to corporate fundamentals.
Samsung Electronics and SK Hynix Trade at Sub-4x PER
Among KOSPI's top 10 companies by market capitalization, Samsung Electronics traded at a 12-month forward PER of 3.82x as of May 28, while SK Hynix stood at 3.99x. Other major constituents showed similarly compressed valuations: SK Square at 2.68x, Hyundai Motor at 8.84x, and KB Financial at 8.86x. The metrics indicate that half of the market's largest companies are trading at single-digit earnings multiples.
Korean Chip Stocks Trade 83% Below US Big Tech Average Valuation
The valuation gap with US technology leaders has widened significantly. NVIDIA trades at a 15.4x forward PER, while Apple commands 35x. The average PER for the top six US companies by market capitalization reached 22.56x. Samsung Electronics and SK Hynix valuations stand approximately 83% below the US big tech average, highlighting the extreme discount applied to Korean semiconductor exporters despite their position as key suppliers to global technology companies.
External Uncertainties and Domestic Liquidity Drive Valuation Gap
Securities firms attribute the extreme undervaluation to multiple factors. Recent increases in bond issuance by US big tech companies to fund artificial intelligence infrastructure investments led to rising CDS premiums, indicators of default risk. Market concerns emerged that these companies might slow AI investment pace, creating preemptive negative sentiment for Korean semiconductor component suppliers. Domestic market-specific liquidity issues, including mechanical selling pressure from single-stock leveraged products near market close, amplified the decline in share prices relative to corporate fundamentals.
64% of KOSPI Stocks Trade Below Book Value
As of May 28, 577 out of 915 KOSPI-listed companies traded below 1x price-to-book ratio (PBR), representing 64% of all listed stocks. A PBR below 1x indicates the company's market capitalization falls short of its book value of net assets. The proportion of sub-1x PBR stocks dropped to 48.9% in April, then climbed steadily through May to reach 63% in July, marking the year's highest level. The 14 percentage point increase over three months reflects the breadth of the valuation compression across the market.
Kiwoom Securities Recommends Hold Strategy Pending Recovery Signals
Kiwoom Securities analyst Han Ji-young advised investors to maintain existing positions while awaiting rebound catalysts to reduce losses. "During the financial crisis, Korean corporate earnings declined nearly 27-30%. If we apply a premium to the current PER of 5.1x, we get approximately 7x, which is still cheap. Because the frequency of rebounds is expected to be higher than further declines, a strategy of holding now and reducing losses through subsequent rebounds is appropriate," Han stated. The firm noted that confirming a sustained recovery requires monitoring several variables: continued strong earnings from leading stocks following SK Hynix's record second-quarter results announced on May 28, improvement in US big tech cash flows, and stabilization of volatility from single-stock leveraged products.
FAQ
What caused KOSPI stocks valuation to fall to 5.13x PER on May 28?
The KOSPI's 12-month forward PER declined to 5.13x as of May 28 due to a combination of external uncertainties and domestic market factors.

Domestic liquidity pressures from single-stock leveraged products added mechanical selling pressure, driving valuations below the 6.82x level seen during the October 2008 financial crisis.
How do Samsung Electronics and SK Hynix valuations compare to US big tech companies?
Samsung Electronics trades at a 3.82x forward PER and SK Hynix at 3.99x as of May 28, approximately 83% below the 22.56x average PER of the top six US companies by market capitalization.

What investment strategy does Kiwoom Securities recommend for Korean stocks?
Kiwoom Securities analyst Han Ji-young recommends maintaining existing stock positions while monitoring recovery signals.

Investors should track leading stocks' earnings sustainability following SK Hynix's record second-quarter results, US big tech cash flow improvements, and stabilization of leveraged product volatility before making portfolio adjustments.
