Midweek Risk-Off in Asian Markets: Korea, Taiwan, and India Lead; Japan and Hong Kong Under Pressure

Overview

This is an intraday/market-day commentary report issued by Goldman Sachs covering trading dynamics across major Asian markets on May 28, 2026. The core conclusion is that rising oil prices combined with upcoming key risk events later this week jointly suppressed risk appetite, resulting in mixed but mostly lower performance across Asian equities. Korea’s tech-heavy market stood out positively—even overtaking the UK to rank as the world’s eighth-largest equity market—while Japan, Australia, and Hong Kong faced downward pressure. Market behavior was dominated by stock-specific moves, with sharp divergence across sectors and individual names, as price action was primarily driven by earnings, placements, and corporate actions.

Core views

Demand-side and event-driven factors: Higher oil prices and looming key risk events heightened risk-off sentiment, prompting investors to adopt defensive positioning. This led utilities, tech, materials, and growth stocks to underperform due to profit-taking. In contrast, energy and certain cyclical stocks held up relatively well, supported by higher oil prices. Regional divergence: Korea’s KOSPI rose 0.65%, emerging as a regional bright spot, mainly lifted by expectations of AI and robotics collaborations. Taiwan’s weighted index edged down 0.24%, but MediaTek and Delta Electronics rallied sharply, with capital rotating back into small- and mid-cap CPO-related stocks. Japan’s Nikkei 225 declined 1.22%, dragged down by steep losses in SoftBank and ARM. China’s CSI 300 slipped 0.28%, though WuXi AppTec surged on strong Q1 results, boosting the healthcare sector. Hong Kong’s Hang Seng Index fell 0.67%, weighed down by growth stocks, though southbound capital flows remained net buyers. Stock and sector dynamics: In Korea, Hyundai Motor Group rose 6.3% and LG Electronics gained 7.6%, both driven by AI collaboration expectations. Daewoo E&C jumped 14% after reporting Q1 operating profit 110% above consensus. In Japan, construction and banking stocks outperformed, while the AI supply chain showed divergence—materials held firm while semiconductor equipment valuations were marked down. In China, domestic GPU plays Cambricon and Moore Threads rose 3.1% and 4.4% respectively, while semiconductor equipment stocks saw profit-taking. ASEAN markets were generally weak; Thailand’s SET index edged lower, though sentiment in the energy sector improved due to policy support for rooftop solar under tiered tariffs.

Analysis framework

The report employs a typical intraday market review methodology, analyzing regions longitudinally and sectors/stocks latitudinally, using cross-market comparisons and intraday price-event mapping to capture market dynamics. The analytical thread follows a transmission chain: 'macro events → market sentiment → capital flows → stock performance.' It first identifies macro variables like oil prices and risk events, then observes index-level reactions across markets, drills down into differentiated sector and stock performance, and finally traces specific catalysts (e.g., earnings releases, placements, partnership rumors, policy adjustments). This approach emphasizes real-time interpretation of intraday/short-term price movements rather than medium-to-long-term fundamental forecasts, focusing on identifying 'what is driving today’s market' and tracking thematic rotation of capital.

Methodology notes

• Industry/Industrial Chain Analysis FrameworkUpstream-Midstream-Downstream Industrial Chain Transmission

  AI Supply Chain Divergence Analysis

  When analyzing the Japanese market, the report breaks the AI industrial chain into upstream materials, midstream equipment, and downstream applications. It observes a divergence where materials held firm while semiconductor equipment (SPE) valuations were marked down, illustrating differing sensitivity and risk-return profiles across segments of the same theme (AI).

• Industry/Industrial Chain Analysis FrameworkSupply-demand framework

  AH Share Premium/Discount Dynamics

  The report repeatedly references price gaps between A- and H-shares (e.g., WuXi AppTec’s AH premium hitting a record -13.5%, CATL’s AH discount narrowing to ~22%), a classic framework for analyzing cross-market capital flows, valuation discrepancies, and arbitrage opportunities, reflecting the supply-demand equilibrium of the same company in different markets.

• Quantitative/Factor/Portfolio TheoryStyle factor analysis

  Growth vs. Value / Quality vs. Dividend Style Rotation

  The report frequently notes shifts in market style—for example, 'quality and dividend styles outperformed while growth factors dragged' in Hong Kong, and 'capital rotated back into small- and mid-cap stocks' in Korea—demonstrating a factor-based market decomposition approach that helps identify investor preferences under different macro environments.

Impact & implications

The report argues that Asian markets are currently in a risk-off mode amid a dense calendar of macro events. Rising oil prices and geopolitical risks (e.g., Trump discussing Iran) are key factors suppressing risk appetite. In this environment, capital exhibits clear thematic rotation: moving away from previously high-flying tech and growth stocks toward energy, cyclicals, healthcare, and defensive quality/dividend styles. AI-related themes remain a key market driver, but momentum has shifted from broad rallies to structural divergence—collaboration expectations (e.g., Korean firms with Google DeepMind, LG with NVIDIA) act as stock-specific catalysts, while earnings delivery becomes the litmus test. Capital actions like placements significantly impact sentiment, as seen with CATL and China Hongqiao. The report cautions that markets may remain cautious until key risk events resolve, with stock-specific moves and thematic rotation likely to persist.

Risks

• Uncertainty surrounding key risk events later this week
• Potential inflationary and monetary policy implications of persistently rising oil prices
• Escalation of geopolitical risks (e.g., Iran situation)
• Impact of large-scale placements and other capital actions on individual stock sentiment
• Valuation adjustment risks as the AI theme shifts from broad rally to structural divergence

What to watch

• Aftermath of Bank of Japan policy decision and post-Golden Week market reopening
• Outcomes of meetings between Korean firms and Google DeepMind, and progress on AI collaborations
• Further developments on rumored NVIDIA-LG Electronics collaboration
• Post-earnings capital rotation trends in China’s CPO-related stocks
• Performance of ASEAN banking sector amid macro headwinds
• Shifts in market risk appetite following resolution of key risk events
