Market Overview
Korean equities fell sharply on July 13, with the KOSPI down 7.77% to 6,894.78 and the KOSDAQ down 4.17% to 802.55. The session was defined by broad risk-off trading, led by heavy selling in semiconductor bellwethers and several large downside moves among high-volume names.
The break below the 7,000 level became the day's headline event. Market reports cited semiconductor selling as the main pressure point, with SK hynix and Samsung Electronics both falling steeply and dragging sentiment across the broader market.
Key Themes
- Semiconductor selloff: Samsung Electronics and SK hynix were at the center of the market decline. Headlines highlighted a KOSPI break below 7,000 as chip names sold off, with SK hynix down more than 12% and Samsung Electronics also under heavy pressure.
- ETF and chip-market attention: Several headlines focused on SK hynix ADR-linked leveraged ETFs launching in the United States, adding to the stock's visibility even as local trading turned sharply negative.
- Biotech volatility: HLB plunged nearly 30% as investors reacted to FDA-related developments around its liver cancer drug resubmission process and manufacturing-facility issues.
- Seasonal appliance strength: Heatwave and rainy-season demand supported appliance-linked names. Paseco and Shinil Electronics both rose more than 20%, while related market headlines also pointed to strong demand for dehumidifier and cooling products.
Stocks in Focus
Samsung Electronics (005930)
Samsung Electronics fell 8.95%, making it one of the key contributors to the day's broad market weakness. The stock was a high-volume bellwether as semiconductor selling dominated the session, and market headlines described the KOSPI's drop below 7,000 as being driven by aggressive selling in chip names.
The company's reference headlines were mixed in subject matter rather than pointing to one single trading trigger. Newsis reported that Samsung Electronics employees will use Google's Gemini AI for company work, while Yonhap reported higher service-material costs linked to chip inflation. TV Chosun also carried a headline on union comments about opposition to a Honam semiconductor plan. Against the broader market backdrop, the stock's move was best explained by sector-wide semiconductor pressure rather than any one company-specific item.
SK hynix (000660)
SK hynix dropped 12.94%, standing out as the sharpest major semiconductor decline among the selected market leaders. Multiple market headlines cited SK hynix directly in the context of the KOSPI losing the 7,000 level, including reports that the stock was down in the 12% range while Samsung Electronics also fell sharply.
The stock also remained in the news because several SK hynix ADR-linked leveraged ETFs were scheduled to launch in the United States on July 13-14. Yonhap, YTN, and Economist all reported on the expected rollout of these ETF products. That attention highlighted global investor interest in the name, but today's local trading was dominated by heavy selling rather than enthusiasm for the ETF-related news.
HLB (028300)
HLB plunged 29.64%, making it one of the day's most notable downside movers. The move followed FDA-related headlines around the company's liver cancer drug program, with Electronic Times reporting that the stock continued to fall after the FDA setback tied to rivoceranib.
Other reference articles added detail to the issue. News1 reported that HLB had obtained FDA inspection observations and started the process for reapproval of its liver cancer drug, while MTN reported that manufacturing-facility issues had become an obstacle even though the company's growth engine remained in focus. The size of the decline showed that investors reacted sharply to the regulatory and manufacturing uncertainty.
Paseco (037070)
Paseco surged 27.61%, bucking the broader market's steep decline and becoming one of the day's standout high-volume gainers. The stock fit the heatwave and seasonal-appliance theme, which was one of the few strong pockets in the session.
Reference headlines linked the rally to extreme heat and demand for cooling appliances. EDaily reported that Paseco and Winix rose together amid "steam-bath" heat, while Money Today reported a rally in window-type air conditioners during Europe's heatwave. A TopStarNews headline also cited a strong intraday move in Paseco on July 13. The stock's gain was therefore closely tied to weather-driven demand expectations rather than the broader index trend.
Shinil Electronics (002700)
Shinil Electronics rose 24.08% on heavy volume, also benefiting from the seasonal appliance theme. The move came as investors looked for names linked to cooling and air-circulation products during a session otherwise dominated by broad market selling.
Among the stock's reference articles, ZDNet Korea reported that Shinil Electronics had launched a "ribbon blade fan" designed for circulator-level air circulation. Other listed headlines focused on education-sector restructuring involving similarly named schools, so the most relevant company-specific item was the new fan product. In the context of the day, Shinil's jump aligned with demand for fans, circulators, dehumidifiers, and other summer appliances.
Kumho Electric (001210)
Kumho Electric fell 21.86%, making it another report-worthy high-volume decliner. The stock's drop placed it among the session's steep downside movers, even though the broader narrative was led by semiconductor weakness.
The directly relevant reference headlines from TopStarNews and JoongAng ENews reported intraday weakness in Kumho Electric on July 13. The selected-stock data showed a much larger final decline of 21.86%, so the reportable point is the severity of the selloff and heavy trading interest, rather than a clearly identified company-specific catalyst.
Market Headlines

Closing Note
The session was sharply negative overall, with semiconductor selling overwhelming the broader market and pushing the KOSPI below 7,000. At the same time, weather-linked appliance names showed that selective theme trading remained active even during a broad selloff.
