SEOUL, July 27 (Reuters) - Further market data has reinforced the severity of South Korea's semiconductor sector decline. Additional reports confirm that the downward pressure on Samsung Electronics and SK Hynix extends beyond initial trading sessions, with analysts noting a broadening sell-off across related supply chain components. The contraction in chip valuations appears more entrenched than previously assessed, suggesting the bear market conditions may persist through the remainder of the quarter as global demand forecasts are revised lower. Industry insiders indicate that inventory adjustments at major fabrication plants will likely continue to weigh on earnings expectations for both companies. This developing situation underscores a deeper structural challenge within the technology sector rather than isolated volatility.
SEOUL, July 27 (Reuters) - South Korea's benchmark stock index fell into bear market territory on Monday after shedding more than a quarter of its value from record highs reached in June, driven by sharp declines in the country's two largest semiconductor manufacturers.
The Kospi index closed at levels marking a decline of 25.9 percent from its peak earlier this year, crossing the technical threshold that defines a bear market. The downturn was heavily weighted by poor performance from Samsung Electronics and SK Hynix, which together account for a significant portion of the exchange's total capitalization.
Samsung Electronics shares tumbled as investors reacted to concerns over global demand for memory chips and intensified competition in the artificial intelligence hardware sector. SK Hynix followed suit, with its stock price eroding alongside its larger rival due to similar headwinds affecting the broader semiconductor industry. The synchronized drop in these tech titans overwhelmed gains from other sectors, pulling the entire market into negative territory.
The rapid descent marks a stark reversal for South Korea's equity markets, which had enjoyed robust growth leading up to June 2026. Analysts attribute the volatility to shifting investor sentiment regarding export-dependent industries and broader macroeconomic uncertainties affecting Asian manufacturing hubs. The semiconductor sector, long considered the engine of South Korea's economic recovery, has faced mounting pressure as supply chain dynamics evolve and consumer electronics demand softens.
Trading volumes remained elevated throughout the session as institutional investors adjusted portfolios in response to the deteriorating outlook for chipmakers. Market participants are now closely monitoring quarterly earnings reports from major technology firms for signs of stabilization or further contraction in revenue projections.
The decline has raised questions about the resilience of South Korea's export-led economy and whether policy interventions will be required to stabilize investor confidence. While some market observers suggest the correction is a necessary adjustment after an extended rally, others warn that deeper structural issues within the tech sector could prolong the downturn.
Regulators have not yet announced any immediate measures in response to the slide, though financial authorities are expected to review current market conditions over the coming days. The extent of the impact on smaller-cap stocks and whether other sectors can provide a counterbalance remains unclear as trading continues into the next session.
Investors await further clarity from corporate guidance issued by Samsung and SK Hynix in the weeks ahead, with many eyeing potential shifts in production forecasts or strategic partnerships that could alter the market trajectory. For now, the Kospi's entry into bear territory underscores the fragility of markets reliant on a narrow set of high-growth industries.
