Korea Stock Market (KRX) Today (August 05): South Korea’s stock market staged a powerful comeback on Wednesday, August 5, as investors rushed back into technology and semiconductor shares after days of heavy selling. The benchmark KOSPI surged sharply in early trading, forcing the Korea Exchange (KRX) to activate a temporary buy-side sidecar to control excessive program buying.
Strong gains on Wall Street, easing concerns over artificial intelligence spending, hopes for progress in U.S.-Iran diplomatic talks, and renewed institutional buying helped fuel one of the market’s biggest rallies in recent weeks.
The rebound also comes after July’s steep correction, with analysts increasingly viewing the recent decline as a potential long-term buying opportunity.

Several positive global and domestic developments lifted investor sentiment across South Korea’s financial markets.
Wall Street closed higher overnight, encouraging investors to return to riskier assets. Concerns over AI-related capital spending also eased, leading to renewed buying in semiconductor stocks.
At the same time, optimism surrounding possible diplomatic progress between the United States and Iran over the Strait of Hormuz reduced worries about global energy supplies and inflation.
Institutional investors rotated back into technology stocks, helping South Korea’s benchmark indices recover sharply after recent volatility.

Korea Stock Market (KRX) Today (August 05): What Should Investors Know?
Investors should note that Wednesday’s rally follows one of the sharpest monthly corrections in South Korean equities since 2008. Morgan Stanley recently upgraded South Korean equities from “Neutral” to “Overweight,” arguing that the recent sell-off has created attractive long-term investment opportunities.
The investment bank expects further stabilisation as leveraged positions continue to unwind and projects that the KOSPI could eventually reach 9,000 points over the longer term.
However, market volatility may remain elevated as investors continue monitoring global AI demand, geopolitical developments in the Middle East, oil prices and central bank policies.
