Der Aufstockungseffekt von Leverage-ETFs hat sich diese Woche in vollen Zügen gezeigt: Wie stark der Rückgang der AI-Aktien in Südkorea gelitten hat

The sharp decline in AI-related stock prices in South Korea this week has underscored the growing volatility of exchange-traded funds (ETFs) with leveraged structures, particularly inverse ETFs. These funds, designed to deliver amplified returns, either positive or negative, based on the performance of their underlying assets, have shown extreme sensitivity during market swings. This week’s sharp sell-off in AI shares triggered a dramatic drop in leveraged ETFs tracking those stocks, illustrating how these products can magnify both gains and losses in volatile markets. The downturn began on Monday, July 13, when major AI-focused companies in South Korea saw their share prices plunge following mixed reports on recent advancements in artificial intelligence research and regulatory concerns over data privacy. By midday on Tuesday, July 14, the Korean Composite Index had fallen nearly 3% within hours, driven largely by investor panic over potential long-term implications for the sector. The rapid decline sparked a cascade effect among investors, many of whom had allocated significant portions of their portfolios to leveraged ETFs tied to AI stocks. Leveraged ETFs, which typically offer daily returns that are multiples, often two or three times, the performance of their benchmark index, were hit hardest. For example, the Inverse S&P KOSPI AI Index ETF, which aims to provide a multiple of the inverse daily return of the S&P KOSPI AI Index, dropped more than 15% in just two trading sessions. Investors who had bought these ETFs in anticipation of a market rebound found themselves facing massive losses instead. Some analysts noted that the leverage factor meant that even small percentage declines in the underlying index could translate into substantial losses for ETF holders. The situation has drawn attention from financial regulators in South Korea, who have been monitoring the increasing popularity of leveraged ETFs amid rising market uncertainty. According to a statement issued by the Financial Services Commission, the agency is reviewing whether additional safeguards should be introduced to protect retail investors from the risks associated with highly leveraged products. The commission emphasized that while such funds can be useful tools for short-term speculation, they carry heightened risk due to their structure and the compounding nature of daily rebalancing. Investors who had previously benefited from the growth of AI stocks in the past year now face the reality of a rapidly shifting landscape. Many had invested in leveraged ETFs expecting continued momentum in the sector, only to find themselves caught off guard by the sudden reversal. Some have begun liquidating positions, while others remain cautiously optimistic, believing the market will eventually stabilize. However, the pace of the decline has left many feeling exposed, especially those who had taken on higher levels of debt to fund their investments. Market experts suggest that the current environment reflects broader trends in global equity markets, where sentiment can shift quickly based on technological developments, policy changes, and macroeconomic factors. With AI remaining a key focus for investors worldwide, the volatility observed in South Korea serves as a warning of the risks inherent in leveraging exposure to high-growth sectors. As the market continues to evolve, the role of leveraged ETFs, and the need for greater transparency and education around their use, will likely remain a topic of discussion among policymakers and financial professionals alike.
