Session at a Glance

KOSPI crashes nearly 11% as AI chip selloff hammers Seoul, Tokyo, and Taipei.

A brutal semiconductor rout ripped through Asia-Pacific on Tuesday after CXMT’s 466% Shanghai IPO debut stoked fears of Chinese memory chip competition, compounding existing anxiety over AI capex sustainability and reports of circular financing among US chip giants. Korea Exchange triggered a sell-side sidecar as SK Hynix and Samsung Electronics cratered, dragging KOSPI to its worst session in years. Tokyo Electron and Advantest pulled the Nikkei down nearly 4%, while Taiwan’s TAIEX shed 4.7% on chipmaker sympathy selling.

Defensive pockets held up. Australia’s ASX 200 added 0.6% as biotech heavyweight CSL rallied, and India’s Nifty 50 flatlined with IT services names like TCS catching a bid. Hong Kong edged higher on consumer-internet strength. The session’s cross-border theme was unmistakable: anything tied to AI semiconductor capex got sold, while defensives and domestic-demand plays absorbed the rotation.

Here are the standout movers across Asia-Pacific’s major exchanges for the session of Tuesday, July 28, grouped by market.

Australia (ASX)

↑ CSL +2.69%

Mega-cap · 119.5 (local)

Why: No single catalyst — CSL rallied as a defensive rotation bid in a risk-off session, with investors fleeing chip exposure into blue-chip biotech and healthcare names.

Pattern: Classic sector-rotation trade: mega-cap defensive outperforms on a day when growth/tech gets sold hard. Momentum continuation if chip selling persists this week.

↓ MIN -2.93%

Mid-cap · 53.1 (local)

Why: No clear catalyst specific to Mineral Resources — likely dragged lower by broader commodity and mining sector weakness amid risk-off sentiment and a firmer US dollar.

Pattern: Mid-cap mining names tend to amplify risk-off moves. The -2.9% dip fits a mean-reversion setup if lithium/iron ore stabilises, but sector tape needs to confirm first.

Hong Kong (HKEX)

↑ 9999 +4.50%

Mid-cap · 199.6 (local)

Why: NetEase caught a bid as investors rotated out of semiconductor exposure into domestic-consumption and gaming names — a relative safe haven within China tech.

Pattern: Consumer internet acting as a defensive hedge within the tech basket mirrors prior chip-selloff episodes. Momentum continuation if sector rotation deepens this week.

↓ 2628 -2.51%

Mid-cap · 27.94 (local)

Why: China Life Insurance drifted lower as Shanghai Composite fell 1.2% — insurers track broad mainland sentiment and bond yields, both soft amid the CXMT-driven capital rotation.

Pattern: Financials tend to lag in sessions dominated by single-stock IPO euphoria (capital reallocation effect). The -2.5% is noise-level unless it breaks a multi-week support.

China — Shanghai (SSE)

↑ 601398 +3.10%

Mega-cap · 7.97 (local)

Why: ICBC rallied after China’s biggest banks launched first repo-linked loans under new lending rules — a structural positive for net interest margin and loan book diversification.

Pattern: Policy-catalyst driven bid in a mega-cap state bank. Fits a macro-catalyst pattern — institutional flows often front-run further regulatory loosening in Chinese financials.

↓ 600030 -0.60%

Mid-cap · 28.09 (local)

Why: CITIC Securities slipped modestly as mainland brokerages underperformed banks — capital rotation toward CXMT IPO likely drained speculative flows from the brokerage sector.

Pattern: A -0.6% move in a mid-cap broker on a volatile day is within normal noise. No breakout or breakdown pattern — sideways drift consistent with low-conviction positioning.

China — Shenzhen (SZSE)

↑ 000333 +1.47%

Large-cap · 85.37 (local)

Why: Midea Group gained modestly as domestic appliance and industrial automation names attracted rotation flows — insulated from the semiconductor selloff hitting export-facing tech.

Pattern: Domestic-demand large-cap holding up on a risk-off day fits the defensive rotation theme. Steady momentum continuation rather than breakout — watch for follow-through.

↓ 002415 -2.30%

Mid-cap · 36.14 (local)

Why: Hikvision fell as the semiconductor supply chain selloff bled into adjacent hardware names — surveillance equipment relies on chips, making it a secondary victim of the rout.

Pattern: Mid-cap tech hardware names often get hit with a one-session lag during chip selloffs. The -2.3% is sector-sympathy selling — mean-reversion candidate if chip names stabilise.

Japan (TSE)

↑ 7974 +3.07%

Mega-cap · 7659 (local)

Why: Nintendo bucked the Nikkei selloff as investors rotated into consumer entertainment — a classic defensive play when semiconductor and AI-capex names get hammered.

Pattern: Mega-cap gaming as a non-AI tech hedge is a recurring pattern during chip routs. The +3% counter-move on a -4% Nikkei day signals strong relative demand — momentum continuation.

↓ 8035 -10.96%

Mid-cap · 5.592e+04 (local)

Why: Tokyo Electron cratered 11% as the global semiconductor equipment selloff intensified ahead of its July 30 earnings — investors fear AI capex cuts will hit wafer fab equipment orders.

Pattern: Pre-earnings selloff amplified by sector contagion from KOSPI chip names. The -11% is a capitulation-level move — historically these overshoot, but earnings on Thursday will set direction.

Singapore (SGX)

↑ Z74 +2.49%

Large-cap · 4.53 (local)

Why: SingTel gained as telecom defensives attracted flows amid the broader tech rout — investors sought yield and stability in Singapore’s largest listed telco.

Pattern: Defensive telecom outperformance during tech selloffs is a textbook sector rotation. The +2.5% is a solid relative move for a large-cap yielder — continuation likely if volatility persists.

↓ H78 -1.51%

Mid-cap · 7.84 (local)

Why: Hongkong Land slipped modestly as the risk-off tone weighed on APAC real estate names — no company-specific catalyst, likely broader HK/Singapore property sector softness.

Pattern: A -1.5% move in a mid-cap property name on a volatile day is within normal range. No clear technical pattern — sideways drift, check broader REIT/property sector momentum.

South Korea (KOSPI)

↓ 000660 -14.65%

Large-cap · 1.55e+06 (local)

Why: SK Hynix plunged 14.7% as the global chip selloff converged with CXMT’s blockbuster Shanghai debut stoking fears of Chinese memory competition — earnings due today added to uncertainty.

Pattern: Capitulation-level move in a large-cap memory chipmaker. Prior -15% sessions in SK Hynix have marked near-term bottoms, but the CXMT competitive threat is a new structural overhang.

Taiwan (TWSE)

↓ 2308 -9.97%

Mid-cap · 1580 (local)

Why: Delta Electronics dropped 10% as the semiconductor supply chain selloff swept Taiwan — the company’s power management and thermal solutions are tied directly to AI server and data centre builds.

Pattern: AI-infrastructure mid-cap getting hit with the full force of the capex-skepticism trade. The -10% is outsized even for a high-beta chip-adjacent name — watch for mean-reversion bounce.

India (NSE)

↑ TCS +4.68%

Mega-cap · 2403 (local)

Why: TCS rallied nearly 5% as India’s IT services sector caught a defensive bid — investors rotated into non-hardware tech with stable recurring revenue amid the semiconductor panic.

Pattern: Mega-cap IT services acting as a tech-sector safe haven is a recurring India pattern during global chip selloffs. Momentum continuation setup if the defensive bid holds this week.

↓ HINDUNILVR -6.16%

Large-cap · 2041 (local)

Why: Hindustan Unilever dropped 6.2% after reporting lower quarterly profit as input costs weighed on margins — the Q1 FY27 earnings miss triggered a sharp post-results selloff.

Pattern: Earnings-driven gap down in a large-cap FMCG name. Post-results selling in Indian consumer staples tends to overshoot by 1-2 sessions — mean-reversion candidate after the dust settles.

New Zealand (NZX)

↑ SPK +2.31%

Mid-cap · 1.99 (local)

Why: Spark New Zealand edged up 2.3% as the telecom defensive bid extended to NZX — investors sought yield and low-volatility exposure amid the regional tech rout.

Pattern: Defensive telecom rotation mirrors SingTel’s move in Singapore. The +2.3% is a solid single-session gain for a mid-cap NZ telco — trend continuation if regional volatility persists.

↓ AIR -1.18%

Large-cap · 0.42 (local)

Why: Air New Zealand dipped modestly as travel and leisure names softened on the risk-off tone — no company-specific catalyst, likely macro sentiment spillover from the broader APAC selloff.

Pattern: A -1.2% dip in a large-cap airline on a volatile day is noise-level. No breakout or breakdown — check oil prices and forward booking data for directional conviction.

Reading the Session

The exchange-by-exchange breakdown above surfaces both market-specific catalysts and cross-border themes. When multiple exchanges move together, look for a macro driver (USD move, commodity price, risk-on/off shift). Isolated single-exchange moves tend to reflect local earnings, regulatory news, or sector rotation.
