Session at a Glance

KOSPI extends historic AI-chip rout as SK Hynix plunges for third straight day, dragging Asia lower.

Asia-Pacific markets traded under the shadow of South Korea’s AI-memory selloff, now in its third consecutive session. SK Hynix broke below ₩1.3 million after a Q2 earnings miss and vague conference call guidance, compounded by fears of Chinese DRAM expansion via CXMT’s mega-IPO and reports of domestic lithography breakthroughs. KOSPI shed another 1.2% after triggering back-to-back circuit breakers earlier in the week.

Japan’s Nikkei was the standout, rising 0.7% as Hitachi surged 6% on strong full-year earnings. But Japanese banks sold off hard — MUFG dropped 3.4% — suggesting the rally was narrow and sector-specific. Hong Kong edged higher on oil-linked names as crude prices firmed, while Shanghai slipped 0.6% on continued consumer-demand softness.

Taiwan told a split story: MediaTek bounced 2.7% on dip-buying, but Quanta Computer cratered nearly 10% after pricing Taiwan’s largest equity offering in 19 years — a $2.16 billion GDS sale — right into the AI selloff. The dilution timing could not have been worse.

Here are the standout movers across Asia-Pacific’s major exchanges for the session of Thursday, July 30, grouped by market.

Australia (ASX)

↑ MIN +3.90%

Mid-cap · 57.79 (local)

Why: No specific catalyst — Mineral Resources likely caught a bid from firming iron ore and lithium spot prices as broader commodity complex held up despite risk-off tone in Asia equities.

Pattern: Mid-cap mining name bouncing within a broader range — looks like mean-reversion off recent weakness rather than a breakout. Watch for follow-through volume to confirm.

↓ NST -3.29%

Mid-cap · 20.02 (local)

Why: No clear headline catalyst — Northern Star dropped despite gold holding near highs, suggesting profit-taking or sector rotation out of gold miners after an extended run in the safe-haven trade.

Pattern: Gold miner pulling back while spot gold stays elevated is a bearish divergence pattern. Could signal momentum exhaustion if the broader ASX gold index confirms the fade.

Hong Kong (HKEX)

↑ 0883 +2.89%

Large-cap · 24.18 (local)

Why: CNOOC rose as crude oil prices gained on Wednesday, providing a tailwind for offshore energy producers. Oil’s strength came amid geopolitical supply concerns and steady demand readings.

Pattern: Large-cap energy names tracking crude higher is a straightforward macro-catalyst trade. CNOOC’s move fits sector rotation into defensives as tech/AI names sold off across the region.

↓ 1810 -2.63%

Large-cap · 31.04 (local)

Why: Xiaomi fell as the broader Asia tech selloff spilled into Hong Kong consumer-tech names. Sentiment was further weighed by underutilized buyback authorization and lingering Q1 profit miss concerns.

Pattern: Xiaomi’s decline fits the broader AI/tech risk-off rotation sweeping Asia this week. Large-cap consumer tech dragged lower by sector contagion rather than company-specific news — watch for stabilisation signals.

China — Shanghai (SSE)

↑ 601857 +3.49%

Large-cap · 11.27 (local)

Why: PetroChina rallied as oil prices firmed on Wednesday, providing a direct commodity tailwind. State-backed energy names also attract defensive positioning when broader A-share markets weaken.

Pattern: Classic sector rotation into energy defensives during a risk-off session. PetroChina’s +3.5% move against a -0.6% Shanghai Composite signals active capital seeking shelter in yield-backed large caps.

↓ 600030 -0.04%

Mid-cap · 28.49 (local)

Why: CITIC Securities was essentially flat at -0.04% — no meaningful directional move. Chinese brokerage volumes have been subdued amid cautious A-share sentiment and limited policy catalyst.

Pattern: A near-zero move on a down day is actually relative strength for a beta-sensitive brokerage name. Not actionable — wait for a directional catalyst like CSRC policy or volume surge.

China — Shenzhen (SZSE)

↑ 000858 +4.51%

Large-cap · 78.56 (local)

Why: Wuliangye jumped 4.5% in a likely technical bounce after extended weakness from the baijiu sector’s cyclical downturn and April’s major accounting restatement. No specific news catalyst identified.

Pattern: Oversold bounce in a beaten-down consumer staple — Wuliangye has been repriced lower through 2026 on structural demand concerns. This looks like mean-reversion rather than a trend change without volume confirmation.

↓ 002415 -0.34%

Mid-cap · 35.62 (local)

Why: Hikvision was essentially flat at -0.34% — no meaningful directional move. The surveillance-tech giant trades in a range constrained by US entity-list overhang and steady domestic demand.

Pattern: Near-zero moves on a negative session suggest the stock is range-bound within a consolidation pattern. Entity-list risk caps upside while domestic demand floors downside — not a momentum setup.

Japan (TSE)

↑ 6501 +6.01%

Large-cap · 5255 (local)

Why: Hitachi surged 6% following strong FY2026 results — revenue rose 8.2% to ¥10.59 trillion and earnings jumped 30.3%, with free cash flow nearly doubling to ¥1.33 trillion year-on-year.

Pattern: Earnings-driven breakout in a large-cap industrial conglomerate. Hitachi’s diversified exposure (energy, rail, digital) insulates it from the AI-chip selloff. Momentum continuation setup if ¥5,300 holds as new support.

↓ 8306 -3.35%

Large-cap · 3525 (local)

Why: MUFG dropped 3.4% as Japanese bank stocks sold off amid broader risk-off sentiment. The decline came ahead of the August 3 earnings report, with investors possibly de-risking positions pre-results.

Pattern: Large-cap bank pulling back near 52-week highs (range ¥2,021–¥3,778) ahead of earnings looks like pre-event de-risking. If results beat, the dip becomes a buy-the-pullback setup; miss accelerates the fade.

Singapore (SGX)

↑ H78 +0.84%

Mid-cap · 8.36 (local)

Why: Hongkong Land edged up 0.8% with no specific catalyst — the REIT/property name may have attracted defensive positioning as investors rotated away from tech exposure in the broader Asia session.

Pattern: Marginal move in a mid-cap property name — not enough conviction to call a pattern. Defensive rotation into real assets is a theme but the magnitude here is noise-level.

↓ O39 -2.05%

Large-cap · 29.17 (local)

Why: OCBC fell 2.1% despite announcing AI-driven wealth client onboarding initiatives. The decline likely reflects broader Singapore bank weakness and regional risk-off rather than company-specific headwinds.

Pattern: Large-cap bank selling off on a risk-off day while announcing growth initiatives is a sector-drag pattern. If the broader tape stabilises, OCBC’s AI-wealth strategy could re-attract buyers on the next uptick.

South Korea (KOSPI)

↑ 051910 +5.59%

Large-cap · 2.455e+05 (local)

Why: LG Chem surged 5.6% in a sharp rebound after KOSPI’s historic two-day rout. Battery and chemical names attracted bargain-hunting as the index stabilised after triggering back-to-back circuit breakers.

Pattern: Oversold bounce in a large-cap that was caught in KOSPI’s indiscriminate selloff. LG Chem’s EV battery exposure gives it a different fundamental profile from memory chips — sector differentiation driving the rebound.

↓ 000660 -5.64%

Large-cap · 1.322e+06 (local)

Why: SK Hynix fell 5.6% for a third consecutive day, extending a 29% three-day decline after a Q2 earnings miss (operating profit 4.7% below estimates) and a vague conference call that amplified peak-cycle fears.

Pattern: This is a momentum crash pattern — structural concerns about memory cycle peak, Chinese DRAM expansion (CXMT IPO), and domestic lithography progress are repricing the entire thesis. Knife-catching is dangerous here.

Taiwan (TWSE)

↑ 2454 +2.70%

Large-cap · 3235 (local)

Why: MediaTek bounced 2.7% on dip-buying after being caught in the broader AI/semiconductor selloff earlier in the week. The chip designer’s diversified mobile and IoT exposure differentiates it from pure-play memory names.

Pattern: Selective dip-buying in non-memory semis while memory continues to crash — classic sector rotation within tech. MediaTek at 3,240 TWD is well off its 52-week high of 4,970, suggesting value hunters are stepping in.

↓ 2382 -9.85%

Mid-cap · 279 (local)

Why: Quanta Computer cratered 9.9% after pricing a $2.16 billion GDS offering — Taiwan’s largest equity sale in 19 years — directly into the AI selloff, maximising dilution impact on existing shareholders.

Pattern: Secondary offering dilution into a weak tape is a textbook negative catalyst. Timing the largest equity raise in decades during an AI rout signals either urgent capital needs or terrible luck. Avoid until the overhang clears.

India (NSE)

↑ WIPRO +2.15%

Large-cap · 187.6 (local)

Why: Wipro rose 2.2% with no specific catalyst — Indian IT services names may have attracted relative-value flows as global investors rotated away from hardware/semiconductor exposure toward services and defensives.

Pattern: Indian IT outsourcers gaining while Asian hardware tech sells off is a recurring rotation pattern. Wipro’s move fits the defensive-tech bid but needs sector-wide confirmation from peers like Infosys and TCS.

↓ BAJFINANCE -0.99%

Mid-cap · 1044 (local)

Why: Bajaj Finance slipped 1% with no clear catalyst — the NBFC heavyweight traded in line with mild profit-taking across Indian financials as Nifty 50 finished near flat for the session.

Pattern: Sub-1% decline in a mid-cap financial on a flat index day is noise. Bajaj Finance remains in a broader uptrend — this move doesn’t signal a pattern change. Check broader sector tape before reading into it.

New Zealand (NZX)

↓ AIR -2.35%

Large-cap · 0.415 (local)

Why: Air New Zealand fell 2.4% with no specific headline — the airline trades thinly and is sensitive to fuel cost expectations, which ticked higher as crude oil firmed during the session.

Pattern: Airline declining on rising oil is a straightforward input-cost pressure trade. AIR.NZ at NZ$0.415 is near multi-year lows — this is trend continuation lower, not a dip-buy setup without a fuel cost reversal.

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.
