Session at a Glance

Nikkei surges 2% on semiconductor strength as memory chip rally lifts Seoul; Hong Kong and China lag.

Asian markets split sharply on Tuesday as the semiconductor and AI trade dominated the session. Japan’s Nikkei rallied 2.1% — extending Monday’s 1,300-point surge — with chip-equipment names like Tokyo Electron leading. Seoul’s KOSPI gained 0.7%, powered by a 4.1% jump in Samsung Electronics after JPMorgan flagged a memory chip supply crunch lasting into 2028. Singapore’s Straits Times climbed 0.6% after OCBC posted record H1 profit.

Hong Kong and mainland China bucked the trend, with the Hang Seng down 1.1% and the Shanghai Composite off 0.8%. Tech names in Hong Kong faced renewed selling pressure, while A-share insurers and consumer discretionary lagged. India’s Nifty slipped 0.5% as Wipro fell on its removal from the benchmark index, replaced by BSE from September 30.

The cross-border theme was clear: AI and memory chip demand drove gains in Northeast Asian exporters while domestically oriented Chinese and Indian names drifted. Oil strength lifted energy plays like CNOOC in Hong Kong, one of the few bright spots in the red session.

Here are the standout movers across Asia-Pacific’s major exchanges for the session of Tuesday, August 11, grouped by market.

Australia (ASX)

↑ CSL +2.87%

Mega-cap · 138.3 (local)

Why: No specific catalyst — CSL continues to trade ahead of its August 18 earnings report, with analysts holding a consensus Buy and a target roughly 20% above current levels.

Pattern: Pre-earnings positioning in a beaten-down mega-cap biotech (down ~22% YTD). Move looks like institutional accumulation ahead of the report rather than a breakout.

↓ WOW -2.04%

Large-cap · 39.83 (local)

Why: No clear catalyst — Woolworths trades near analyst consensus targets with a Hold rating; the slip may reflect profit-taking after an 8% rally over the past 52 weeks ahead of August 26 earnings.

Pattern: Mean-reversion drift. Stock is trading above the average analyst target of A$36.49, suggesting the recent run may be extended. Isolated, not sector-wide.

Hong Kong (HKEX)

↑ 0883 +3.59%

Large-cap · 24.24 (local)

Why: CNOOC rallied alongside rising crude oil prices, which climbed further in Asian trading. The offshore driller benefits directly from higher Brent as a pure-play upstream producer.

Pattern: Commodity momentum play — CNOOC tracks oil prices closely. The move aligns with a broader energy-up theme visible across European and Asian oil names this week.

↓ 1810 -3.48%

Large-cap · 26.66 (local)

Why: Xiaomi fell 3.5% amid a broader Hong Kong tech selloff and headlines about Mercedes losing ground in China’s premium auto market — a negative read-across for Xiaomi’s EV ambitions.

Pattern: Momentum breakdown in HK tech. Xiaomi is down nearly 40% YTD and the session move extends a multi-week downtrend. Sector rotation away from China consumer discretionary.

China — Shanghai (SSE)

↑ 601857 +1.94%

Large-cap · 11.06 (local)

Why: PetroChina gained nearly 2% as rising global oil prices lifted the state-owned energy giant. Defensive energy names outperformed in a weak Shanghai session.

Pattern: Defensive sector rotation — energy was one of the few green sectors on a down day for the Shanghai Composite. Classic flight-to-value pattern within A-shares.

↓ 601318 -1.44%

Large-cap · 52.55 (local)

Why: Ping An Insurance declined 1.4% as China’s July CPI eased to 0.5%, stoking deflation concerns that weigh on insurer investment returns and premium growth expectations.

Pattern: Macro-driven sector drag — Chinese insurers and financials are sensitive to the deflation narrative. The move is part of a broader A-share financial sector pullback, not isolated.

China — Shenzhen (SZSE)

↑ 000333 +0.38%

Large-cap · 85.62 (local)

Why: Midea Group edged up 0.4% — no clear catalyst. The home-appliance giant was a relative outperformer on a weak Shenzhen tape, likely supported by its international expansion narrative.

Pattern: Flat-range hold. A sub-0.5% move in a large-cap is noise rather than signal. Midea has been range-bound; no breakout or breakdown pattern forming.

↓ 002415 -2.86%

Mid-cap · 36.37 (local)

Why: Hikvision dropped nearly 3% with no specific headline — the surveillance-tech name remains under pressure from geopolitical overhang and weaker domestic demand expectations.

Pattern: Continuation of a downtrend in Chinese tech hardware. The move fits a sector-rotation pattern away from names with US sanctions risk. Broader Shenzhen tech weakness.

Japan (TSE)

↑ 8035 +4.13%

Mid-cap · 5.675e+04 (local)

Why: Tokyo Electron surged 4.1% on the global semiconductor rally, extending gains from strong fiscal Q1 earnings (revenue up 33% YoY). AI and memory chip capex momentum is the driver.

Pattern: Momentum continuation in semis — Tokyo Electron is a direct beneficiary of the HBM/AI capex cycle. The move tracks US chip strength and Samsung’s memory supply-crunch narrative.

↓ 8306 -1.52%

Large-cap · 3510 (local)

Why: Mitsubishi UFJ dipped 1.5% despite positive analyst coverage. Japanese bank shares pulled back as the BoJ rate-hike timeline remains uncertain and global bond yields softened after weak US jobs data.

Pattern: Mean-reversion pullback after a strong run. MUFG is rated a momentum pick by multiple analysts but profit-taking into rate uncertainty is natural. Sector-wide Japanese bank dip.

Singapore (SGX)

↑ O39 +2.90%

Large-cap · 31.18 (local)

Why: OCBC rallied 2.9% after reporting record H1 2026 net profit of S$4.19 billion, up 13% YoY, driven by a 36% surge in non-interest income and record wealth management revenue.

Pattern: Earnings-driven breakout. Record profit plus a 15% dividend increase is a textbook catalyst for re-rating. Singapore banks are in a structural wealth-management growth cycle.

↓ C6L -6.18%

Mid-cap · 7.13 (local)

Why: Singapore Airlines dropped 6.2% on its ex-dividend date (S$0.29 per share). The steep decline also reflects weaker fundamentals — profit fell 82% in Q2 on fuel costs and Air India losses.

Pattern: Ex-dividend gap-down compounded by fundamental weakness. The S$0.29 dividend accounts for roughly 4% of the drop; the extra 2% is sentiment. Not a buy-the-dip setup given earnings headwinds.

South Korea (KOSPI)

↑ 005930 +4.13%

Mega-cap · 2.395e+05 (local)

Why: Samsung Electronics surged 4.1% after JPMorgan said the memory chip supply crunch could last two more years, reinforcing the HBM/AI demand thesis that has powered Korean semis in 2026.

Pattern: Momentum continuation — Samsung has rallied from its recent base on successive AI/memory catalysts. The move is part of a global semiconductor re-rating theme, not isolated.

↓ 006400 -4.57%

Mid-cap · 4.595e+05 (local)

Why: Samsung SDI fell 4.6% after announcing it will buy out GM’s 49.99% stake in their Indiana EV battery joint venture, citing weaker-than-expected EV demand — the market reads it as a capital burden.

Pattern: Negative event catalyst — JV buyouts on slowing demand signal capital misallocation risk. The EV battery sector is repricing lower as demand growth disappoints. Isolated company event.

Taiwan (TWSE)

↑ 2454 +1.52%

Large-cap · 4020 (local)

Why: MediaTek gained 1.5% on the broader semiconductor tailwind as AI chip demand lifts the entire Asia tech supply chain. No company-specific catalyst in the last 36 hours.

Pattern: Sector momentum — MediaTek is riding the same AI/memory wave lifting Tokyo Electron and Samsung. TAIEX semis tend to move in sympathy with US and Korean chip names.

↓ 2317 -0.57%

Large-cap · 263 (local)

Why: Hon Hai (Foxconn) slipped 0.6% despite headlines about Tencent AI spending — the mild decline may reflect concerns over Apple’s Jefferies downgrade on iPhone yield and growth worries.

Pattern: Minor pullback in a large-cap contract manufacturer. The Apple downgrade creates a modest negative read-across for Foxconn’s consumer electronics assembly revenue. Not a trend change.

India (NSE)

↑ TCS +0.63%

Mega-cap · 2441 (local)

Why: TCS edged up 0.6% despite disclosing employee data exposure alerts. The muted reaction suggests investors view the incident as contained — India’s IT bellwether remains a defensive anchor.

Pattern: Range-bound drift. A sub-1% move in a mega-cap IT services name is noise. TCS trades as a low-beta defensive within India’s market; no breakout or breakdown evident.

↓ WIPRO -0.88%

Large-cap · 183.9 (local)

Why: Wipro fell 0.9% after NSE announced BSE will replace it in the Nifty 50 index from September 30 — triggering expected passive fund selling as trackers rebalance out of the name.

Pattern: Index-exclusion catalyst — classic pattern where passive outflows from ETFs and index funds create mechanical selling pressure. Expect further drift into the September 30 effective date.

New Zealand (NZX)

↑ FPH +0.90%

Large-cap · 42.58 (local)

Why: Fisher & Paykel Healthcare gained 0.9% — no clear catalyst. The medtech name trades as a defensive large-cap on the NZX and benefits from mild risk-off rotation on quieter sessions.

Pattern: Low-volatility defensive drift. Sub-1% move in a thin market — no pattern signal. FPH tends to attract flows when NZ investors rotate out of cyclicals.

↓ AIR -1.16%

Large-cap · 0.425 (local)

Why: Air New Zealand dipped 1.2% — no specific headline. The airline sector faces headwinds from rising oil prices, which pressure fuel costs and squeeze margins across Asia-Pacific carriers.

Pattern: Oil-price-driven headwind for airlines — mirrors Singapore Airlines’ weakness. Rising crude is a cross-regional theme hurting carrier margins. The move is sector-wide, not company-specific.

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.
