Asian markets diverged on Friday: Japan’s Nikkei 225 vaulted above 52,000 and Korea’s KOSPI extended record territory on a powerful tech bid, while China fell after a seventh straight month of factory contraction (manufacturing PMI 49.0). The yen stayed weak, the offshore yuan softened, and semiconductors led regional leaders higher.
Market Recap: Winners, Laggards, and the Setup
- Japan: The Nikkei 225 punched through 52,000 intraday, with TOPIX also notching fresh highs. Gains集中 in semiconductor and equipment names (chip gear, testers, materials) alongside megacaps. Momentum was helped by robust global tech earnings and a softer yen, which boosts exporters’ earnings translation.
- South Korea: The KOSPI remained in uncharted territory, propelled by Samsung Electronics and SK hynix, as AI infrastructure demand keeps HBM memory and advanced packaging in focus. Autos and shipbuilders added breadth.
- China: Mainland and Hong Kong benchmarks slipped after October manufacturing PMI printed 49.0, marking seven consecutive months below 50. The weak print weighed on cyclicals (industrials, chemicals) and kept the offshore yuan under pressure.
- Southeast Asia: Markets were mixed; tech-linked names and energy pockets held better, while China-exposed sectors lagged.
What’s Driving the Divergence
1) The AI Capex Supercycle
Japan and Korea sit at the upstream of AI compute—from lithography and test (Japan) to HBM memory (Korea). As hyperscalers and sovereign clouds scale out, regional semis, equipment, and component suppliers continue to benefit from multi-year capex visibility.
2) Currency Tailwinds (and Headwinds)
A weak yen amplifies Japan’s earnings leverage, especially for global tech exporters. Conversely, yuan softness reflects China’s growth worries and weighs on foreign flows into A-shares and China-sensitive equities across the region.
3) Macro Pulse in China
The 49.0 PMI reading underscores soft domestic demand and trade frictions, reinforcing the case for targeted fiscal/credit easing. Until manufacturing stabilizes, risk appetite toward China cyclicals is likely to remain capped.
Sector Moves to Watch
- Semiconductors & Equipment: Leaders in Tokyo and Seoul continue to price in AI server demand, HBM tightness, and advanced packaging buildouts.
- Autos & Robotics (Japan): Yen weakness plus industrial automation demand supports OEMs and factory-automation names.
- Internet & Platforms (Korea/Japan): Beneficiaries of ad recovery and cloud-AI adoption; watch guidance on AI monetization and capex pass-through.
- China Cyclicals: Under pressure on PMI; defensive growth (healthcare, staples) and policy-favored tech hardware may see relative inflows if stimulus chatter rises.
FX & Rates Snapshot
- JPY: Hovering in the mid-¥150s per USD, cushioning exporters and risk assets in Tokyo but keeping an eye on policy rhetoric.
- CNH: Softer after PMI, reflecting growth and capital-flow concerns; stability efforts remain a key watch-point.
- KRW: Firm alongside equity strength; Korea’s current-account dynamics and tech-led inflows support the tone.
Investor Playbook: 5 Things for the Week Ahead
- Follow-through in Tokyo/Seoul tech: Watch whether semis and equipment sustain leadership into month-end rebalancing.
- China policy signaling: Any hints of targeted easing (credit to manufacturers/SMEs, local stimulus) could stabilize cyclicals and FX.
- Earnings beats vs. capex guides: For Asia tech, capex outlooks and AI order backlogs matter more than one-off revenue beats.
- Currency sensitivity screens: Re-rank portfolios for yen/krw/cnh exposures; earnings translation can dominate near-term revisions.
- Positioning & flows: Track Northbound/Southbound and foreign flow data—breadth is as important as index prints at records.

Conclusion
Asia’s market narrative has split: Japan and Korea are riding the AI supply-chain wind to fresh records, while Chinastruggles to shake off manufacturing contraction. Until Beijing’s policy pulse turns convincingly stimulative—or global demand re-accelerates—expect two-speed Asia: tech-heavy North Asia at the front, China cyclicals lagging, FX and flows acting as accelerants.
FAQ
Why are Japan and Korea hitting records?
A powerful tech upcycle—especially AI chips, HBM memory, and chip equipment—plus supportive FX (weak yen) and favorable earnings revisions.
What sank Chinese shares today?
A 49.0 manufacturing PMI (7th straight contraction) undercut sentiment, pressuring cyclicals and the yuan.
Does a weak yen always help Japanese stocks?
Not always—but for exporters and global tech names, it typically boosts earnings translation and competitiveness.
Where’s the near-term risk?
A sudden FX reversal, policy disappointments in China, or signs that AI capex is pausing could test the rally’s breadth.
