Kosdaq gains momentum as chip stocks jitter

Korean stocks ended mixed Tuesday, as the tech-heavy Kosdaq extended its rally on expectations of stronger investor inflows while continued weakness in major chipmakers weighed on the benchmark KOSPI. The benchmark KOSPI closed at 6,358.95, up 1.62 percent from the previous session. The index climbed to 6,389.40 shortly after the opening bell but reversed course later in the day. Foreign and institutional investors sold a net 369.7 billion won ($257.7 million) and 539.1 billion won worth of shares, respectively. Retail investors, meanwhile, bought a net 810 billion won. SK hynix rose 0.64 percent to close at 1,577,000 won, while Samsung Electronics gained 0.21 percent to finish at 240,000 won. Sentiment toward memory chipmakers continued to weaken overnight following reports that China's largest memory chipmaker, CXMT, is considering building a new semiconductor plant in Beijing. Although details such as production capacity and investment size were not disclosed, the prospect of increased memory supply added downward pressure to chip stocks. Still, U.S. memory chip stocks managed to rebou

Korean won seen as biggest Asian FX winner from yen support

The Korean won is poised to be the biggest beneficiary among Asian currencies after U.S. and Japanese authorities carried out a coordinated yen-buying intervention, given the won's relatively high sensitivity to moves in the Japanese yen, analysts said Tuesday. "The suppression on the dollar-yen rate should favor a lower dollar-won rate, along with other Asian currencies against the U.S. dollar, with the Korean won emerging as a clear beneficiary," said Stephen Chiu, chief emerging markets FX strategist at Bloomberg Intelligence. Barclays also noted in a research published Monday that yen-sensitive Asian currencies, particularly the Korean won, could extend gains in the short term. While most Asian currencies have relatively low sensitivity to moves in the Japanese yen, the Korean won, Singapore dollar and Thai baht are the most responsive, in that order, it said. "Following an almost uninterrupted decline in the dollar-won exchange rate since early July ... the currency (won) received additional support after the dollar-yen rate fell sharply amid reports of Japanese intervention," said

Korean investors flock to leveraged US ETFs, take another hit

A retail investor surnamed Min knew the risks before pressing the buy button. But the urge to make up for the gains he had missed overwhelmed his better judgment. In early July, the 29-year-old purchased 5 million won ($3,496.26) worth of Direxion Daily Semiconductor Bull 3X Shares, an exchange-traded fund (ETF) known by its ticker, SOXL. The fund seeks to deliver three times the daily return of the Philadelphia Semiconductor Index. When he checked his account the next morning, his position was already down more than 10 percent. He saw the decline as another buying opportunity and added to his holdings. His losses continued to deepen, eventually reaching 30 percent. "I naively thought that the bad news surrounding chip stocks would end just after I bought in, followed by a sharp rebound," he said. "I let the fear of missing out take over." Min is one of many retail investors who have piled into triple-leveraged U.S. ETFs as chip stocks have languished at home and Korean authorities have tightened regulations on trading single-stock leveraged ETFs tied to Samsung Electronics and SK hynix.

The index opened 3.6 percent lower, slipped below the 6,500 mark and extended losses throughout the session.

KOSPI rockets 18% in record-breaking rally

KOSPI surged nearly 18 percent on Friday to reclaim the 6,500 level, posting record gains in both percentage and point terms as chip stocks staged a dramatic rally. The benchmark closed at 6,595.45, up 17.91 percent from the previous session. It jumped immediately after the open, triggering a buy-side sidecar at 9:06 a.m., and extended gains through the session. The only other time KOSPI rose more than 10 percent in a single day was Oct. 30, 2008. Foreign and institutional investors led the buying, snapping up a net 7.22 trillion won ($5.06 billion) and 1.18 trillion won in shares, respectively. Retail investors, meanwhile, net sold 8.25 trillion won. SK hynix surged 29.95 percent to close at 1,718,000 won. Korea's second-largest company by market value touched the 30 percent daily limit during the session. Samsung Electronics also jumped 26.81 percent to 262,500 won, its biggest daily percentage gain on record. The rally erased losses from the previous three sessions. SK hynix had fallen 29.9 percent and Samsung Electronics 19.34 percent over the three trading days through Thursday. Stron

Korea to launch $13.9 bil. sovereign wealth fund for strategic industries

The government will launch a 20 trillion won ($13.9 billion) sovereign wealth fund next year to make long-term investments in strategic domestic industries, including artificial intelligence, chips, robotics, defense and biotechnology, officials said Friday. The fund will be established within the Korea Investment Corp. (KIC). The plan was announced Friday at a meeting of economic affairs ministers chaired by Minister of Finance and Economy Koo Yun-cheol. The government plans to capitalize the fund with about 16 trillion won in shares it holds in state-run financial institutions, including the Korea Development Bank, the Export-Import Bank of Korea and the Industrial Bank of Korea. It will also contribute roughly 4 trillion won in shares received in lieu of inheritance and gift taxes. Additional funding may come from surplus tax revenue generated by the semiconductor industry and from private donations. Unlike existing policy funds, the new vehicle will operate as "ultralong-term patient" capital, with no predetermined maturity or liquidation date. It will make direct equity investments i

Leveraged ETF fiasco weighs on Lee administration's economic team

When President Lee Jae Myung took office in June 2025, he promised to lift Korea's benchmark index to 5,000. Within a year, the KOSPI reached that target and kept surging to peak at 9,000, powered by a semiconductor boom and expectations of corporate governance reform. Barely a year into his presidency, the rally is unraveling. KOSPI has fallen back to around 5,000, this time amid an even more troubling development: extreme volatility. At the center of the volatility are single-stock leveraged exchange-traded funds (ETFs) tied to Samsung Electronics and SK hynix. The issue is weighing heavily on the Lee administration's financial team, and calls are growing for the resignations of top policymakers, as investors largely regard their countermeasures as makeshift and far from a fundamental solution. Introduced on May 27, the funds were intended in part to draw Korean retail investors away from leveraged products listed in Hong Kong and to ease pressure on the won-dollar exchange rate. However, the products have magnified gains and losses in some of the country's most heavily traded shares,

Korea's sidecar system faces test as triggers hit record high

Once a rarely used emergency brake, the sidecar mechanism has become a recurring feature of Korea's stock market amid bouts of extreme volatility. Its growing use has raised questions about its effectiveness, as stocks have often continued to plunge until circuit breakers were triggered, industry officials said Thursday. According to the Korea Exchange, sidecars have been triggered 43 times in the benchmark KOSPI this year, far surpassing the 26 activations recorded during the 2008 global financial crisis. They have also been triggered 29 times on the secondary Kosdaq, bringing the total number of sidecar activations in Korea’s stock markets this year to 72. Introduced in 1996, the sidecar is designed to prevent sharp price swings in the futures market from spilling over into the spot market through program trading. On KOSPI, a sidecar is triggered when KOSPI 200 futures move by at least 5 percent and remain at or beyond that threshold for one minute. On Kosdaq, it is activated when Kosdaq 150 futures move by at least 6 percent and the spot index moves by at least 3 percent in the same

Seoul stocks plunge for 2nd day amid growing panic sell-off

KOSPI tumbled below the 6,000-point mark after suffering steep losses for the second consecutive day, deepening concerns that the market sell-off has entered a self-reinforcing phase, analysts said Wednesday. KOSPI closed at 5,663.24, down 5.98 percent from the previous session. The benchmark index opened at 6,089.11 and climbed as high as 6,228.52 during the session. Selling then intensified rapidly, with a sell-side sidecar issued at 9:06 a.m. and a circuit breaker activated at 12:32 p.m. The index plunged to the 5,200-level intraday before paring some of its losses. Foreign and retail investors led the selling spree, dumping 764.4 billion won ($527.8 million) and 2.93 trillion won in shares, respectively. Institutional investors purchased 3.61 trillion won in shares, but the buying was not enough to halt the plunge. SK hynix fell 9.61 percent to close at 1,401,000 won despite announcing record quarterly earnings, while Samsung Electronics plunged 5.23 percent to close at 208,500 won. SK hynix shares plunged 22.85 percent over two consecutive day. Although SK hynix posted record second

DDH builds trust in dental care with AI

Few patients readily accept being told they have four cavities, need a root canal and must have a tooth extracted. Their first response is often skepticism: Can I trust the dentist’s judgment? Is all that treatment really necessary? DDH, a Korean dental artificial intelligence (AI) startup, believes technology can help bridge that trust gap — a challenge the company says extends well beyond Korea. "The industry's biggest pain point, both in Korea and abroad, is patients' distrust of dentists," DDH founder and CEO Her Soo-bok told The Korea Times in an interview, Monday. DDH's solution, called Pano, is designed to make dental diagnoses easier for patients to understand. The process begins with a panoramic X-ray. The company's AI model analyzes the image and uses different colors to highlight areas that may show signs of cavities, gum disease or other conditions. A dentist then reviews the findings and determines whether treatment is necessary. "Such records help build patient trust and prevent potential legal disputes," Her said. He said dentistry accounts for the largest share of house
