KOSPI has declined more than 20% from its peak, entering correction territory, as experts debate whether Korean stocks are overheated. The dispute centers on conflicting signals: valuation metrics like PER (8.7x) and PBR (2.7x) remain below global peers, yet economic indicators including narrowing yield spreads and slowing semiconductor price growth suggest potential overheating. According to Daishin Securities data as of the 8th, KOSPI's forward PER stands significantly below the S&P 500 (22.7x), NASDAQ (29.2x), and Taiwan's TAIEX (24.9x), while the Buffett indicator reached 221% in June—far above the 2000-2025 average of 70.2%.
KOSPI Valuation Metrics Remain Below Global Benchmarks
According to Daishin Securities, KOSPI's forward PER as of the 8th stands at 8.7x, compared to the S&P 500's 22.7x, NASDAQ's 29.2x, Taiwan's TAIEX 24.9x, and Japan's Nikkei 17.3x. The PBR indicator shows KOSPI at 2.7x versus NASDAQ's 7x and Taiwan's 5.5x. Lee Kyung-min, researcher at Daishin Securities, stated that KOSPI's forward PER level has fallen to levels comparable to the 2008 global financial crisis. Lee assessed the current level as an undervalued zone where earnings are rising across semiconductors and multiple sectors while stock prices have declined. Lee Jae-man, researcher at Hana Securities, stated that the current decline is not due to problems with corporate fundamentals but represents a psychological oversold zone, and that sufficient energy has accumulated to break through the 10,000 level in the long term.
Economic Indicators Signal Potential Market Overheating
The Buffett indicator, representing market capitalization as a percentage of GDP, reached 221% for KOSPI in June, significantly exceeding the 2000-2025 average of 70.2%. According to the St. Louis Federal Reserve Economic Data (FRED), the US 10-year and 2-year Treasury yield spread stood at 0.38 percentage points as of the 9th, the lowest level since April of last year. Kim Young-ik, adjunct professor at Hanyang University Future Talent Education Center, explained that long-term rates falling more sharply than short-term rates reflects expectations of lower future economic growth and inflation rates.
Memory Semiconductor Sector Faces Growth Concerns
According to the Ministry of Trade, Industry and Energy's export-import trends, DRAM (excluding modules) export prices fell 4% month-over-month in the previous month, and SSD export prices dropped 5%. This marked the first month-over-month decline in DRAM export prices since September of last year. Park Yu-ak, researcher at Kiwoom Securities, downgraded Samsung Electronics' target price from 430,000 won to 390,000 won on the 8th, stating that memory price growth is gradually slowing and additional memory purchases by PC and smartphone companies are being limited, leading to a slowdown in EPS growth from the second half. On the same day, Lee Min-hee, researcher at BNK Investment & Securities, presented a target price of 1.85 million won for SK Hynix, stating that AI infrastructure investment momentum is slowing and earnings momentum is expected to decline.
