Session at a Glance

TSMC powers Taiwan to near-2% gain while Samsung’s 6% plunge drags KOSPI to session lows.

The AI chip supply chain drew a sharp dividing line across Asia-Pacific on Tuesday. Taiwan’s TAIEX surged nearly 2% as TSMC rallied almost 4% on fresh Mizuho CoWoS capacity upgrades and record AI earnings momentum — the stock has more than doubled in the past year. South Korea went the other way: Samsung Electronics cratered 5.8% after analysts flagged Q2 operating profit falling below 100 trillion won on outsized incentive provisions, dragging the KOSPI down over 2%.

China was mixed but leaned constructive. The Shanghai Composite gained 0.44% as insurance heavyweight Ping An jumped 3.75% and tech-adjacent names caught a bid, while the Hang Seng slipped 0.63% on energy weakness. Tencent bucked the Hong Kong trend, climbing 2.3% after securing a multi-year $2.8 billion DRAM supply deal with CXMT to build out its AI infrastructure.

Australia’s ASX 200 shed 0.64% amid cautious sentiment, while India’s Nifty 50 added 0.63% led by consumer staples. The session’s overarching theme: markets are repricing which chipmakers will capture AI capex — and which will miss earnings doing it.

Here are the standout movers across Asia-Pacific’s major exchanges for the session of Wednesday, July 1, grouped by market.

Australia (ASX)

↑ CSL +3.16%

Mega-cap · 118.4 (local)

Why: No clear single-day catalyst — CSL has been rebounding from 52-week lows near A$90 after FY26 guidance revision, with analysts still rating the biotech as undervalued ahead of August earnings.

Pattern: Looks like a mean-reversion bounce off deeply oversold levels — the stock is trading well below its 52-week high of A$275, so relief rallies can be sharp on light newsflow.

↓ COL -4.19%

Mid-cap · 23.35 (local)

Why: No clear catalyst — Coles Group’s 4.2% drop likely reflects defensive-sector rotation out of consumer staples as broader ASX sentiment turned cautious and bond yields ticked higher.

Pattern: Isolated single-day weakness in a low-volatility name — more consistent with position unwinding or ex-date mechanics than a trend reversal. Watch for follow-through before reading signal.

Hong Kong (HKEX)

↑ 0700 +2.28%

Mega-cap · 429.8 (local)

Why: Tencent rallied after confirming a $2.8 billion multi-year DRAM supply deal with CXMT for AI server infrastructure, plus continued momentum from Weixin Pay’s international expansion push.

Pattern: Momentum continuation — Tencent is building an AI infrastructure narrative that gives the stock a second growth vector beyond gaming. The DRAM deal signals serious capex commitment investors are pricing in.

↓ 0883 -3.61%

Large-cap · 20.32 (local)

Why: CNOOC dropped 3.6% with no company-specific headline — likely tracking weaker crude oil sentiment and broader energy sector rotation in Hong Kong as tech names attracted capital.

Pattern: Sector rotation pattern: energy lagging while tech leads on AI capex headlines. CNOOC’s move is directionally consistent with Hang Seng underperformance driven by old-economy heavyweights.

China — Shanghai (SSE)

↑ 601318 +3.75%

Large-cap · 49.53 (local)

Why: Ping An Insurance surged 3.75% as the heavily discounted valuation attracted buyers — the stock sits well below its 52-week high of ¥74.88, with a consensus Strong Buy and 8.2% dividend yield.

Pattern: Mean-reversion from deeply oversold territory with fundamental support — 17 analysts at Strong Buy, wide discount to price targets around ¥78. Looks like institutional re-accumulation.

↓ 601988 -1.22%

Mid-cap · 5.65 (local)

Why: Bank of China dipped 1.2% on no specific catalyst — likely mild profit-taking in state-owned bank names after a multi-week rally in Chinese financials. Volume appeared routine.

Pattern: Low-conviction pullback in a low-beta name — not unusual for SOE banks to give back small gains on quiet days. No trend break unless follow-through selling materializes this week.

China — Shenzhen (SZSE)

↑ 300059 +5.25%

Mid-cap · 21.45 (local)

Why: East Money Information surged 5.25% — likely tracking the constructive Shanghai session and renewed retail brokerage activity as China’s A-share volumes picked up on positive PMI expectations.

Pattern: Brokerage stocks are high-beta proxies for market sentiment in China. East Money’s outsized move on a day Shanghai gained only 0.44% suggests leveraged retail participation is accelerating.

↓ 300750 -2.33%

Mega-cap · 383.8 (local)

Why: CATL dropped 2.3% as the battery giant pulled back from recent highs near ¥392 with no specific headline — likely sector rotation away from EV supply chain into AI-adjacent tech names.

Pattern: Healthy consolidation within a broader uptrend — CATL is still well above its 52-week low of ¥249. The pullback aligns with the session’s AI-over-EV rotation theme visible across Asia.

Japan (TSE)

↑ 7974 +2.42%

Mega-cap · 6980 (local)

Why: Nintendo gained 2.4% amid renewed media M&A speculation after NBCU gaming tie-up headlines surfaced, adding to the AI-fatigue rotation into consumer entertainment names on the TSE.

Pattern: Sector rotation beneficiary — Nintendo has been catching bids as a non-AI Japanese large-cap whenever semiconductor names wobble. The media M&A chatter adds a speculative premium layer.

↓ 4519 -3.36%

Mid-cap · 7281 (local)

Why: Chugai Pharmaceutical fell 3.4% on no clear catalyst — likely profit-taking in Japan’s healthcare sector after a strong run, with capital rotating toward entertainment and tech names.

Pattern: Isolated pullback in a defensive name during a risk-on session for Japanese equities. Nikkei gained 0.59% led by consumer cyclicals, suggesting pharma underperformance is rotational, not fundamental.

Singapore (SGX)

↑ Z74 +0.91%

Large-cap · 4.45 (local)

Why: Singtel edged up 0.9% on steady telco demand — no specific headline, but the stock continues to benefit from its data centre and regional connectivity buildout narrative across Southeast Asia.

Pattern: Low-volatility grind higher in a defensive yield name. Sub-1% moves in Singtel are noise, but the stock’s steady bid reflects income investors parking capital as regional sentiment stays mixed.

↓ A17U -1.20%

Mid-cap · 2.46 (local)

Why: CapitaLand Ascendas REIT slipped 1.2% — no catalyst, but Singapore REITs broadly weakened as US Treasury yields stayed elevated, pressuring rate-sensitive income vehicles across the region.

Pattern: Rate-sensitivity trade — REIT weakness when bond yields are firm is textbook. A17U’s move is directionally consistent with the global rates backdrop rather than any property-specific issue.

South Korea (KOSPI)

↑ 000270 +2.54%

Mid-cap · 1.415e+05 (local)

Why: Kia Corporation gained 2.5% despite the KOSPI selloff — likely benefiting from sector rotation out of semiconductors into Korea’s auto exporters, which are less exposed to AI earnings risk.

Pattern: Defensive rotation within a weak market — auto names acting as a safe haven while Samsung and chip stocks get repriced. Kia’s outperformance by 8 percentage points vs KOSPI signals strong relative demand.

↓ 005930 -5.84%

Mega-cap · 3.145e+05 (local)

Why: Samsung Electronics plunged 5.8% after analysts projected Q2 operating profit below ₩100 trillion due to outsized incentive payment provisions, reigniting concerns about AI investment profitability.

Pattern: Earnings revision-driven selloff in a mega-cap that anchors the entire KOSPI. The 5.8% single-day drop on pre-earnings downgrades often triggers follow-through selling as funds de-risk ahead of July 23 results.

Taiwan (TWSE)

↑ 2330 +3.94%

Mega-cap · 2505 (local)

Why: TSMC surged 3.9% after Mizuho raised CoWoS advanced packaging capacity forecasts on surging server CPU demand — the stock now accounts for over 40% of the TAIEX and has doubled in a year.

Pattern: Momentum continuation on structural AI demand — TSMC’s high-performance computing is 61% of revenue and advanced nodes 74% of wafer sales. Analyst upgrades are reinforcing, not leading, the trend.

↓ 2317 -1.20%

Large-cap · 248 (local)

Why: Hon Hai (Foxconn) slipped 1.2% despite the strong TAIEX session — likely mild profit-taking in the contract manufacturer as capital concentrated into TSMC’s purer AI semiconductor exposure.

Pattern: Relative underperformance within a strong tape suggests capital is becoming more selective about AI beneficiaries — pure-play chipmaking (TSMC) over assembly (Hon Hai). Divergence worth watching.

India (NSE)

↑ HINDUNILVR +2.99%

Large-cap · 2182 (local)

Why: Hindustan Unilever rallied 3% on no specific headline — consumer staples led the Nifty higher as rural demand recovery hopes and monsoon progress supported the FMCG sector broadly.

Pattern: Sector-wide consumer staples bid in India, consistent with domestic rotation into defensives. HUL often leads when macro optimism for rural India improves — check monsoon updates for confirmation.

↓ TCS -1.55%

Mega-cap · 2000 (local)

Why: TCS fell 1.55% as Indian IT services faced continued pressure from global enterprise spending caution and rotation out of tech into consumer names within the Nifty.

Pattern: Mirror image of the HUL trade — capital rotating from IT services into staples. TCS weakness on a green Nifty day is a relative-strength breakdown that often precedes further sector underperformance.

New Zealand (NZX)

↑ SPK +2.40%

Mid-cap · 1.92 (local)

Why: Spark New Zealand gained 2.4% on no clear catalyst — the telco may be attracting yield-seeking flows in a thin NZX session as investors position defensively ahead of mid-year rebalancing.

Pattern: Low-liquidity bounce in a yield stock — NZX daily volumes are thin enough that even modest institutional buying can produce outsized percentage moves. Not a high-conviction signal without follow-through.

↓ MEL -2.06%

Mid-cap · 5.7 (local)

Why: Meridian Energy slipped 2.1% — no clear catalyst, but New Zealand utilities have been consolidating after a strong H1 run as investors rotate toward higher-beta opportunities.

Pattern: Profit-taking in a defensive utility after a period of outperformance. Meridian’s pullback is modest and orderly — more consistent with portfolio rebalancing than any fundamental deterioration.

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.
