롤러코스터에 올라탄 한국 증시: ‘검은 월요일’의 악몽과 숨 가쁜 반등의 기록 > K-wave Trends

The primary driver of this sharp volatility is undoubtedly the easing of geopolitical risks from the Middle East and the subsequent rebound of U.S. tech stocks. As both Iran and Israel refrained from further military action and signaled a de-escalation of tensions, the fear of the worst-case scenario that had been weighing on the market has somewhat dissipated. Overnight, the Philadelphia Semiconductor Index surged over 5%, and key tech stocks such as Micron, Intel, and NVIDIA regained vitality due to an influx of bargain hunting, providing a direct tailwind to the domestic market. This improvement in external factors created an optimal environment for domestic semiconductor leaders, which had entered oversold territory following the previous day's crash, to attempt a rapid technical rebound.

The extreme anxiety in the market was clearly evidenced by indicators across the board. The KOSPI 200 Volatility Index (VKOSPI), known as the 'Korean fear index,' soared to the 87 level during trading, hitting an all-time high since its inception in 2009, which proves how precarious investors perceive the current market situation to be. Furthermore, the simultaneous triggering of 'buy sidecars'—where program buy orders are temporarily suspended—in both the KOSPI and KOSDAQ markets suggests that market volatility is exceeding controllable limits. The record of over 20 sidecars triggered in the first half of the year alone is an exceptional and threatening situation, reminiscent of the nightmare during the 2008 financial crisis.

In terms of supply and demand, a clear confrontation has formed between aggressive bargain hunting by individuals and institutions and the continuous exodus of foreign investors. While foreigners have maintained a net selling position for 22 consecutive trading days, maintaining a conservative stance on the Korean market, the securities industry interprets this not as a simple exit, but as a process of profit-taking and portfolio rebalancing following the rapid rise in stock prices. In tandem, institutions stood at the forefront of index defense through large-scale net buying, and individual investors also supported the market floor by injecting funds through various channels, including ETFs. This imbalance in supply and demand is a typical phenomenon that occurs during the process of a market bottoming out; whether foreign selling eases will be the key to market stability.

The foreign exchange market also acted as a key variable that either fueled or calmed the stock market's volatility. The won-dollar exchange rate, which once threatened the mid-to-high 1,500 won range, fell to the 1,510 won level following verbal intervention by foreign exchange authorities and the injection of fine-tuning liquidity, which contributed significantly to the recovery of investor sentiment. As concerns over energy-driven inflation eased somewhat and the authorities' will to stabilize the market was confirmed, the runaway exchange rate halted, and foreign investors' anxiety about the Korean market appears to have softened. The stabilization of the exchange rate acts as a defensive shield that regulates the speed of foreign capital outflow, strengthening the foundation for the domestic stock market to seek a rebound without further sharp declines.

The fate of semiconductor leaders, represented by Samsung Electronics and SK Hynix, is the decisive yardstick for the success or failure of this market trend. These stocks, which caused a major shock the previous day by giving up their psychological support lines of '300,000 won' and '2 million won' respectively, regained their dignity among the top market caps by showing double-digit gains in just one day. In particular, SK Hynix's steep rise multiplied the market's rebound momentum, serving as an opportunity for the market itself to prove that the previous day's crash was driven by irrational fear. However, as the concentration on large-cap stocks remains and a differentiated market continues where gains and losses are clearly divided by sector, careful and selective response is required from investors.
