Korea Stock Market (KRX) Today (October 15): South Korea’s stock market faced another sharp sell-off on Thursday, October 15, as renewed concerns about artificial intelligence (AI) investments and rising US inflation weakened investor confidence. The benchmark KOSPI opened 5.59% lower at 5,673.01, while the technology-heavy KOSDAQ fell 4.79% to 784.45, according to a morning report by MoneyToday.
The steep declines prompted the Korea Exchange (KRX) to activate emergency sell-side trading curbs on both markets, temporarily suspending program trading for five minutes. The latest fall extended a difficult period for Korean equities, with semiconductor stocks facing pressure from global technology losses and growing concerns about competition from Chinese chipmakers.
Korea Stock Market (KRX) Today (October 15): Why Is the Korean Stock Market Down Today?
South Korean shares came under renewed pressure as investors reassessed the outlook for technology companies and the potential returns from heavy AI-related spending. Weakness in global chip stocks added to the selling pressure, while concerns about inflation and interest rates made investors more cautious about growth-oriented shares.

The sell-off also reflected growing worries about competition in the semiconductor industry. Chinese memory-chip maker ChangXin Memory Technologies (CXMT) has made progress in developing denser DRAM technology, raising concerns that South Korean manufacturers could face stronger competition and pressure on future profit margins.
Recent losses in Samsung Electronics and SK hynix have amplified the impact on the wider market because both companies carry significant weight in the KOSPI.
Key Reasons Behind the Market Fall
- Concerns about AI profitability: Investors are questioning how quickly large investments in AI infrastructure will generate returns, triggering a reassessment of technology stock valuations.
- Growing Chinese semiconductor competition: Progress by CXMT has raised concerns about future competition in the memory-chip market and the potential impact on pricing and margins.
- Weakness in global technology stocks: Losses among US semiconductor companies have spilt over into Asian markets, putting additional pressure on Korean chipmakers.
- Inflation and interest-rate uncertainty: Higher-than-expected US inflation has revived concerns about borrowing costs remaining elevated, which can weigh on growth-oriented companies.
- Foreign investor selling: Reports of heavy foreign selling during the recent market decline have added to downward pressure on Korean equities.
Korea Stock Market (KRX) Today (October 15): KOSPI Plunges 336 Points
South Korea’s benchmark KOSPI opened sharply lower on October 15 as investors continued to sell technology and semiconductor stocks. MoneyToday reported that the index opened at 5,673.01, down 335.80 points, or 5.59%, from the previous session.
The decline triggered a sell-side sidecar at 9:07 a.m. local time. The mechanism temporarily suspends the validity of program-trading sell orders for five minutes when the relevant futures index crosses the exchange’s specified decline threshold and remains there for the required period.
The measure is intended to help manage abrupt market volatility; it does not close the entire stock exchange.
