SEOUL — As the KOSPI continues its robust upward trajectory, the South Korean Exchange-Traded Fund (ETF) market is witnessing a massive influx of capital, characterized by a stark polarization between winning sectors and losing strategies. According to recent data from the Korea Financial Investment Association (Kofia), the total net assets of domestic ETFs reached 466.11 trillion won as of May 12, marking a significant 18.5% increase in just one month.
During this period, the number of listed ETFs also grew from 1,088 to 1,107, reflecting the industry's aggressive push to capture investor interest through specialized products. However, the distribution of this growth is far from uniform. While thematic ETFs focusing on defense, robotics, nuclear power, and secondary batteries have proliferated, the lion's share of investor capital is being vacuumed into semiconductor-related instruments.
The Semiconductor Hegemony
The current market sentiment is overwhelmingly dominated by the mantra of "following the giants"—Samsung Electronics and SK Hynix. Currently, there are 54 ETFs dedicated to the semiconductor sector listed in Korea. To meet the skyrocketing demand, major asset managers are either launching new targeted products or restructuring existing ones to increase the weight of these two industry leaders.
Mirae Asset Global Investments recently listed the ‘TIGER Semiconductor TOP10 Covered Call Active’ ETF, while Samsung Asset Management introduced the ‘KODEX Semiconductor Target Weekly Covered Call’ ETF. In a notable move, Samsung Asset Management rebranded its 'KODEX AI Semiconductor' to 'KODEX AI Semiconductor TOP Plus,' simultaneously hiking the combined allocation of Samsung Electronics and SK Hynix from 40% to 50%.
The performance of these products has been nothing short of explosive. Over the past month (April 13 – May 12), 'TIGER 200 IT Leverage' topped the charts with a staggering 148.20% return. It was followed closely by 'KODEX Semiconductor Leverage' (105.20%) and 'TIGER Semiconductor TOP10 Leverage' (92.18%). Four out of the top five performing ETFs were tied to semiconductors or the broader IT sector.
The "Inverse Meltdown" and KOSDAQ Exodus
While semiconductor bulls are celebrating, those betting against the market are facing a grim reality. Inverse ETFs, which profit when the market falls, have seen their values nearly halved. The ‘PLUS 200 Futures Inverse 2X’ recorded the sharpest decline at 48.46%, followed by several other ‘Double Inverse’ (popularly known as "Gop-bus" in Korea) products which all suffered losses near the 50% mark.
Simultaneously, the KOSDAQ market is experiencing a notable "exodus." As the KOSDAQ's performance lags behind the KOSPI, investors are engaging in stop-loss selling. The 'KODEX KOSDAQ 150' saw a net outflow of 1.33 trillion won over the past month—the second-largest outflow in the entire ETF market. Other KOSDAQ-related leveraged and active ETFs also dominated the list of products losing capital.
Risks of Extreme Concentration
Despite the euphoria surrounding the chip sector, market analysts are beginning to sound the alarm regarding the extreme concentration of capital. The concern is that a heavy reliance on a few specific stocks could lead to massive systemic losses if a market correction occurs.
This concentration is expected to intensify with the scheduled launch of single-stock leverage ETFs for Samsung Electronics and SK Hynix on May 27. Demand is already high; over 40,000 investors have already completed the mandatory preliminary education required to trade these high-risk single-stock leveraged and inverse products.
"The ETF market is currently showing a very distinct tilt toward memory semiconductors," noted Park Yu-an, a researcher at KB Securities. "Because the weight of top-tier stocks has increased so rapidly during the AI investment boom, the market structure has become vulnerable. Any significant profit-taking or rebalancing could trigger a massive, sudden outflow of capital from these ETFs."
Experts advise that while the growth potential of the AI and semiconductor industries remains high, investors should exercise caution. A strategy excessively concentrated on a single theme or specific stocks can offer high rewards, but it also leaves portfolios highly exposed to volatility and sector-specific downturns.
