Korean stock market volatility doubled that of Japan and Taiwan this year due to semiconductor concentration, Eugene Investment & Securities reported. Samsung Electronics and SK Hynix contributed over 78% to first-half gains, with daily fluctuations of 5-6% versus 1-2% for comparable markets. The concentration in few semiconductor companies created higher downside risk, according to analyst Heo Jae-hwan, contrasting with Taiwan where TSMC's 42% market cap translated to only 30-40% of overall market contribution.
Korean Semiconductor Stocks Show 5-6% Daily Volatility Versus 1-2% in Taiwan and Japan
Samsung Electronics and SK Hynix drove domestic market concentration with over 78% contribution to first-half price gains. Daily price fluctuation rates for Korean semiconductor stocks reached 5-6%, while Taiwan and Japan semiconductor stocks maintained 1-2% volatility levels. In Taiwan's market, TSMC holds a 42% market capitalization ratio, but TSMC and other regional semiconductor players including Japan's Kioxia contributed 30-40% to overall market gains. Heo noted the concentration phenomenon caused Korean market volatility, stating the rapid rise centered on few companies and industries increased downside risk. The analyst added that dividend yields declined significantly as market capitalization expanded, reducing their stabilizing effect on the market.
KOSPI 12-Month Forward P/E Drops to 6-7x, Lowest Since 2008 Financial Crisis
KOSPI's 12-month forward price-to-earnings ratio fell to 6-7x, marking the lowest level since the 2008 global financial crisis. Semiconductor stocks' 12-month forward P/E dropped to 4-5x following price corrections. Non-semiconductor KOSPI sectors' P/E returned to 8.6x, matching levels before last year's April. Heo assessed that further market declines will stabilize, noting the adjustment in semiconductor stock prices gradually reduced the neglect of other stocks.
Eugene Investment Recommends Gradual Weight Increase in Semiconductors and Alpha Sectors
The domestic market will show a consolidation pattern, according to Heo's analysis. The analyst emphasized the need to gradually increase allocation to semiconductors and alpha sectors during this period. Non-semiconductor KOSPI sectors gained valuation attractiveness as their P/E ratios returned to pre-April levels. Heo stated that machinery, shipbuilding, and cyclical sectors including consumer and banking stocks require attention comparable to semiconductors.
