Korea's KOSPI 200 Volatility Index (VKOSPI) reached a record high while the US Fear and Greed Index remained relatively stable, marking an unusual divergence between the two markets. VKOSPI closed at 86.87 on the previous trading day, down 0.31%, after hitting an all-time high of 96.94 on May 29—surpassing the 89.30 level recorded during the 2008 financial crisis. The divergence stems from extreme concentration in semiconductor stocks, with Samsung Electronics and SK Hynix accounting for over 50% of KOSPI's market capitalization and contributing 78.3% of the index's gains in the first half of the year. This concentration creates amplified volatility when these stocks fluctuate, contrasting with the US S&P 500 where semiconductor companies represent approximately 18% of the index, allowing other sectors to offset volatility.
VKOSPI Records Historic High While US Index Stays Stable
According to Korea Exchange data, VKOSPI reached 96.94 on May 29, the highest level since the exchange began officially publishing the index on April 13, 2009. This exceeded the unofficial index level of 89.30 recorded on October 29, 2008, during the global financial crisis. VKOSPI measures expected 30-day volatility annualized from KOSPI 200 option prices. Levels above 20 indicate average volatility, above 30 signal expanded volatility, and above 40 represent fear territory.
The US Fear and Greed Index, which quantifies market sentiment on a 0-100 scale, rose to 71 (greed) in May but remained in the 25 (fear) to 47 (neutral) range during the recent technology stock correction. This index combines seven indicators including market momentum, stock price strength and breadth, put-call options demand, junk bond demand, volatility (VIX), and safe-haven demand. Scores of 0-24 indicate extreme fear, 25-44 fear, 45-54 neutral, 55-74 greed, and 75-100 extreme greed.
In early March, when geopolitical risks including US-Iran war concerns hit markets, VKOSPI surged to 80.37 while the Fear and Greed Index plunged to 6, with both indicators moving in the same direction. The current divergence reflects different index compositions.
Semiconductor Concentration Drives Korean Market Volatility
The US S&P 500 maintains semiconductor company weighting at approximately 18%, allowing other sectors to offset volatility when chip stocks correct. In contrast, Samsung Electronics and SK Hynix together exceed 50% of KOSPI's market capitalization in an ultra-concentrated structure. This means shocks to a few stocks directly translate into market-wide volatility expansion.
Eugene Investment & Securities analyzed that the current stock correction stems not from deteriorating corporate fundamentals but from supply-demand volatility caused by excessive capital concentration in a few semiconductor companies. Samsung Electronics and SK Hynix accounted for 78.3% of KOSPI's gains during the first-half surge. This contribution rate significantly exceeds that of overseas leading stocks: Taiwan's TSMC (38.9%), Japan's Kioxia and SoftBank (36.8%), and the US Magnificent 7 (13.4%).
As a result, daily fluctuation rates (standard deviation) for US, Taiwan, and Japanese markets with evenly distributed fundamentals remained stable at 1-2%, while Korean market volatility soared to more than double these levels. The phenomenon intensified after single-stock semiconductor 2x leveraged ETFs launched in late May, with capital inflows creating a "short gamma" structure where selling begets more selling during price swings.
Analysts Recommend Diversification Into Value Stocks
The correction has increased Korean market valuation attractiveness. KOSPI's 12-month forward price-to-earnings ratio (P/E) dropped to 6-7x, the lowest level since the 2008 global financial crisis. Excluding semiconductors, KOSPI sector P/E ratios also fell to 8.6x, approaching historical lows.
Heo Jae-hwan, researcher at Eugene Investment & Securities, stated: "The domestic stock market will likely show a period of consolidation with further declines stabilizing. As semiconductor stock corrections ease the neglect of other stocks, strategies to expand allocation into machinery, shipbuilding, cyclical stocks, and other sectors with improved valuation appeal will be effective during this period."
Na Jeong-hwan, researcher at NH Investment & Securities, commented: "As volatility increases, investors are driven to short-term responses and shaken by peak concerns. However, stock prices ultimately follow fundamentals. While peak signals are appearing, the conditions that end bull markets—earnings momentum slowdown and liquidity tightening—have not yet been confirmed. Until those signals emerge, the answer lies in areas with high earnings visibility: AI infrastructure, undervalued earnings stocks relative to profits, and premium consumption."
Corporate earnings forecasts remain solid, leading experts to emphasize managing risk through asset allocation diversification rather than indiscriminate selling.
FAQ
What caused VKOSPI to reach a record high on May 29?
VKOSPI hit an all-time high of 96.94 on May 29, driven by extreme concentration in semiconductor stocks. Samsung Electronics and SK Hynix account for over 50% of KOSPI's market capitalization, and their 78.3% contribution to index gains in the first half created amplified volatility. The launch of single-stock semiconductor 2x leveraged ETFs in late May intensified capital concentration and created a "short gamma" structure that magnifies price swings.
How does Korean market concentration compare to the US stock market?
The US S&P 500 maintains semiconductor company weighting at approximately 18%, with evenly distributed fundamentals across sectors producing daily fluctuation rates of 1-2%. In contrast, Samsung Electronics and SK Hynix together exceed 50% of KOSPI's market capitalization, causing Korean market volatility to surge to more than double US levels. This structural difference explains why VKOSPI reached crisis-level highs while the US Fear and Greed Index remained in the 25-47 range.
What investment strategies do analysts recommend during this volatility?
Eugene Investment & Securities recommends expanding allocation into machinery, shipbuilding, cyclical stocks, and other sectors with improved valuation appeal as semiconductor stock corrections ease. NH Investment & Securities advises focusing on areas with high earnings visibility including AI infrastructure, undervalued earnings stocks relative to profits, and premium consumption. KOSPI's 12-month forward P/E ratio of 6-7x represents the lowest valuation since the 2008 financial crisis, suggesting increased price attractiveness despite volatility.
