■ Semiconductor ETF rebalancing to concentrate flows into chip equipment and materials suppliers: Seven semiconductor exchange-traded funds facing index reconstitution this month hold a combined 18.9436 trillion won in net assets, and rebalancing trades are expected to cluster on the 8th, an options expiration day. In the TIGER Semiconductor TOP10 fund, Samsung Electronics (005930) exceeds the 25% single-stock cap by 1.98 percentage points, forcing a reduction of roughly 209.8 billion won. Mid-cap suppliers such as Isu Petasys and Wonik IPS (240810) are expected to see buying demand equivalent to as much as 27.5% of their average daily trading value.
■ LG Electronics secures North American supply base in AI cooling market: LG Electronics (066570) signed a long-term agreement with North American infrastructure company Air Control Concepts (AIR) to supply chillers for AI data centers totaling 5 gigawatts, locking in a stable order book worth trillions of won. After cumulative orders topped 600 billion won in the first half of this year, analysts say the company could reach 1 trillion won in chiller revenue earlier than its original target of late next year.
■ AI investment scope widening to memory and power infrastructure: The chief investment officer at AllianceBernstein (AB), which manages about 1,404 trillion won, forecast that AI spending will remain substantial over the next 12 to 24 months, with the investment scope broadening into memory, power and data center efficiency. South Korean chipmakers hold a strategically important position in high-bandwidth memory and DRAM, giving them significant demand and pricing potential, according to the assessment.
[News of Interest to Stock Investors]
1. Semiconductor ETFs Facing Rebalancing Send Flows Into Chip Suppliers
Key points: Seven semiconductor ETFs facing scheduled index reconstitution this month held combined assets under management of 18.9436 trillion won as of the 2nd, with TIGER Semiconductor TOP10 (10.5974 trillion won) and SOL AI Semiconductor TOP2+ (6.0157 trillion won) accounting for most of that total. In the TIGER Semiconductor TOP10 fund, Samsung Electronics exceeds the 25% per-stock cap by 1.98 percentage points, making a reduction of roughly 209.8 billion won unavoidable. Samsung Securities (016360) estimated buying demand of about 90 billion won for SK hynix (000660) and about 80 billion won for SK Square (402340), and projected inflows of around 20 billion won each for Hanmi Semiconductor (042700), Jusung Engineering (036930), Isu Petasys and Wonik IPS. With Jusung Engineering up 37.0%, Hanmi Semiconductor up 26.5% and Wonik IPS up 25.6% over the past month, some investors are wary of a pullback once the rebalancing is complete.
2. LG Electronics Hits Jackpot in U.S. With Chillers, Landing 5GW Deal
Key points: LG Electronics signed a long-term agreement (LTA) with North American infrastructure platform company Air Control Concepts (AIR) to supply 5 gigawatts worth of chillers for AI data centers. The industry estimates the total contract at trillions of won over three to five years, a large deal equivalent to about 5% of next year's projected global increase in data center capacity of 108 gigawatts. With cumulative orders for AI data center cooling solutions topping 600 billion won in the first half of this year, the company is now expected to reach 1 trillion won in chiller revenue sooner than its original target of late next year. LG Electronics is building a chiller plant in Windsor, Virginia, targeting start-up in the first half of next year, and is also in talks to expand its supply lineup to include coolant distribution units (CDUs), a core component of server liquid cooling.
3. "AI Investment to Run Another One to Two Years, Benefiting Memory and Power"
Key points: Ray Chou, chief investment officer for thematic equities at AllianceBernstein (AB), which manages about 1,404 trillion won, forecast that AI-related spending will remain substantial over the next 12 to 24 months, with the investment scope broadening from training clusters into inference, memory, storage and power. South Korean chipmakers hold a strategically important position in high-bandwidth memory and DRAM, and supply concentration along with the necessity of accelerated computing support their demand and pricing potential, according to the assessment. Companies that resolve power bottlenecks — in grid equipment, cables, liquid cooling and on-site generation — were also cited as promising investments, while a prolonged energy supply shock was identified as a risk that would push up funding costs for the AI industry. As evidence that the current AI boom differs from the dot-com bubble, the assessment pointed to profitable companies in cloud, advertising and productivity improvement leading the actual spending.

Key points: According to a report by the Center for Technology and National Security (CTS), a Washington-based think tank, semiconductor plants in mainland China had secured 343 ASML immersion DUV lithography machines as of early this year, about 270 of them NXT:1980i models. China bought 89 to 90 units in each of 2024 and 2025, spending more than $13 billion, and is applying multi-patterning techniques to mass-produce Huawei Ascend AI accelerators and advanced memory. CTS warned that if the trend continues, China could produce up to 434 million AI chips a year at the level of Nvidia's H100 by 2035. The report's authors said Samsung Electronics and SK hynix could also benefit indirectly from export restrictions on China, making the question of tighter China curbs a key variable for South Korea's chip sector.
Key points: Samsung Electronics is building a semiconductor test fab on a 265,895-square-meter site in the Yen Binh industrial complex in Thai Nguyen province, Vietnam, with total investment across Samsung Vietnam Semiconductor's (SVS) first and second plants reaching 5.48 trillion won. The first-floor line of the first plant will begin equipment installation next July and start operating in the fourth quarter, while the second floor is scheduled for equipment installation in May 2028 and operation in October. Samsung Electro-Mechanics (009150) has also decided to invest 2.51 trillion won in the same complex to produce FC-BGA substrates for AI chips, giving concrete shape to a blueprint in which Samsung affiliates collectively turn Vietnam into a hub for the AI chip value chain. Under the two-track structure, high-value memory such as HBM stays concentrated in Cheonan and Onyang in South Korea while commodity memory is dispersed to Vietnam — a supply chain strategy designed to respond flexibly to shifting global tariffs.
6. "Taking On Tesla": Hyundai Motor, Nvidia and LG Form Autonomous Driving Triangle
Key points: LG and Nvidia have launched a project to commercialize a next-generation AI-defined vehicle (AI DV) platform, with cooperation accelerating after LG Group Chairman Koo Kwang-mo and Nvidia CEO Jensen Huang signed a memorandum of understanding in August. Hyundai Motor (005380), Nvidia and LG have formed an "AI DV triangle" in which they handle vehicle and driving data, AI computing and autonomous driving brains, and digital in-vehicle infotainment (IVI), respectively. Hyundai Motor plans to mass-produce Nvidia-based Level 2++ vehicles from 2028, and LG Electronics IVI systems are seen as likely to be installed. LG Display (034220) is also developing automotive displays aimed at the AI DV era, including pillar-to-pillar OLED panels running from the driver's seat to the passenger seat and slidable OLED, widening the range of LG Group affiliates set to benefit.
