Session at a Glance

SoftBank dethrones Toyota as Japan’s most valuable company; KOSPI surges to record highs on AI frenzy.

AI infrastructure spending dominated the Asia-Pacific session. SoftBank surged 14% after announcing a €75 billion AI investment in France, overtaking Toyota as Japan’s most valuable company for the first time in over two decades. The move lifted the Nikkei above 67,000. South Korea’s KOSPI exploded 3.7% to fresh all-time highs as Nvidia CEO Jensen Huang’s planned Korea visit sparked a broad rally in chip and platform names — Samsung Electronics briefly topped ₩2,000 trillion in market cap.

Taiwan rode the same AI wave, with TAIEX gaining 1.35% as Computex 2026 kicked off in Taipei. Indian IT stocks led the Nifty’s gainers on global tech sentiment spillover. Hong Kong tracked higher on tech strength, though mainland China lagged after May’s manufacturing PMI slipped below 50, signalling mild contraction.

The session’s clear dividing line: AI-linked names surged across every market, while old-economy heavyweights (Toyota, BYD, Hindustan Unilever) sold off on sector rotation and soft macro data.

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

Australia (ASX)

↑ RIO +1.55%

Mega-cap · 188.5 (local)

Why: Rio Tinto edged higher alongside a firmer iron ore tape and continued momentum from a 90% one-year rally driven by strong commodity demand and disciplined capital returns.

Pattern: Momentum continuation within a strong uptrend — the stock is extended but grinding higher on no fresh catalyst, typical of mega-cap commodity leaders in a commodity upcycle.

↓ CSL -2.49%

Mega-cap · 94.2 (local)

Why: No clear catalyst — CSL sold off in a session where defensive healthcare names underperformed as capital rotated into tech and resources. Broader ASX was essentially flat.

Pattern: Sector rotation away from defensives into cyclicals and tech. The -2.5% move looks like profit-taking in a crowded mega-cap name, not a breakdown pattern.

Hong Kong (HKEX)

↑ 1810 +2.43%

Large-cap · 28.72 (local)

Why: Xiaomi rallied on renewed interest in its EV growth ambitions after a pullback, with the broader Hong Kong tech complex catching a bid from the global AI rally and positive Hang Seng sentiment.

Pattern: Mean-reversion bounce off a sharp pullback — valuation reset drew buyers. The +2.4% move fits a dip-buy pattern within a larger uptrend driven by EV segment expansion.

↓ 9618 -0.97%

Large-cap · 112.4 (local)

Why: JD.com slipped as China’s May manufacturing PMI dipped below 50, signalling softening domestic consumer demand. A $10 million insider sale at KE Holdings added to cautious sentiment on China consumer plays.

Pattern: Macro-driven drag — the sub-50 PMI print weighs on domestic consumption names. The -1% move is mild and fits a range-bound consolidation rather than a directional breakdown.

China — Shanghai (SSE)

↑ 601988 +1.19%

Mid-cap · 5.93 (local)

Why: Bank of China gained modestly as state-owned bank shares attracted defensive buying while the broader Shanghai Composite dipped on weak PMI data — a rotation into yield and safety.

Pattern: Defensive sector rotation — SOE banks tend to bid when growth names sell off on soft macro. The +1.2% is consistent with slow-grind accumulation, not breakout momentum.

↓ 600030 -1.46%

Mid-cap · 25.67 (local)

Why: CITIC Securities declined as the soft May PMI weighed on sentiment for Chinese financials tied to capital markets activity. No firm-specific catalyst — check broader brokerage sector tape.

Pattern: Macro drag on a cyclical financial name — brokerages are high-beta to market turnover expectations. The -1.5% move is consistent with a risk-off session for mainland equities.

China — Shenzhen (SZSE)

↑ 000333 +1.05%

Large-cap · 81.7 (local)

Why: Midea Group edged higher with no firm-specific headline — likely benefiting from its AI-enabled smart home and robotics positioning as global AI enthusiasm spilled into China’s tech-adjacent industrials.

Pattern: Gentle momentum continuation in a quality large-cap that straddles consumer and industrial automation themes. The +1% move is subdued relative to peers — no breakout signal.

↓ 002594 -2.63%

Large-cap · 93.65 (local)

Why: BYD dropped 2.6% as the sub-50 May PMI compounded ongoing margin pressure from China’s EV price war. Nio’s new budget EV launch intensifies competition at the low end of the market.

Pattern: Sector headwind plus macro drag — BYD is caught between a contracting domestic manufacturing cycle and rising EV competition squeezing margins. The move extends a multi-week drift lower.

Japan (TSE)

↑ 9984 +14.02%

Mega-cap · 8541 (local)

Why: SoftBank surged 14% to overtake Toyota as Japan’s most valuable company after announcing a €75 billion AI infrastructure investment in France and amid expectations of OpenAI and SB Energy IPOs.

Pattern: Momentum breakout to new highs — the stock is up 90% YTD on a structural AI re-rating. This is a thematic momentum trade, not mean-reversion. Volume and breadth confirm conviction.

↓ 7203 -4.49%

Mega-cap · 2906 (local)

Why: Toyota fell 4.5% as SoftBank officially dethroned it as Japan’s most valuable company — a symbolic blow compounded by weakening EV sales and a rework of its electrification strategy.

Pattern: Sector rotation out of old-economy auto into AI/tech. Toyota is down 10% YTD while SoftBank is up 90% — a textbook growth-vs-value divergence trade accelerating on a single session.

Singapore (SGX)

↑ D05 +1.47%

Mega-cap · 62.84 (local)

Why: DBS Group rose 1.5% with no firm-specific headline — likely tracking broader ASEAN banking strength on steady regional growth expectations and continued dividend appeal for yield-seeking investors.

Pattern: Slow grind higher in a well-owned mega-cap bank — the move is consistent with accumulation in a high-dividend name during a risk-on session. No breakout, just steady bid.

↓ Z74 -0.46%

Large-cap · 4.34 (local)

Why: SingTel dipped marginally on no clear catalyst — the telecom sector underperformed as capital chased higher-beta tech and financial names in a risk-on session across Asia.

Pattern: Mild sector rotation drag on a defensive telecom. The -0.5% is noise within a consolidation range — no directional signal. Low-volatility name doing what it does in a risk-on tape.

South Korea (KOSPI)

↑ 035420 +16.03%

Mid-cap · 2.715e+05 (local)

Why: Naver surged 16% as Nvidia CEO Jensen Huang’s planned Korea visit sparked expectations of AI collaboration with Korean tech platforms. Naver was reportedly on Huang’s official meeting schedule.

Pattern: Catalyst-driven breakout — the Jensen Huang visit is a fresh thematic trigger layered on top of KOSPI’s record-setting AI rally. The +16% move is event-driven, not mean-reversion.

↓ 006400 -5.23%

Mid-cap · 6.52e+05 (local)

Why: Samsung SDI fell 5.2% despite the KOSPI’s record rally — the battery maker has been under pressure from foreign investor selling, though bargain hunters stepped in on energy storage system potential.

Pattern: Counter-trend laggard in a broad rally — classic sector divergence where AI/chip names surge while battery/EV supply chain names get sold. Bargain-hunting flows suggest a potential bottoming pattern.

Taiwan (TWSE)

↑ 2382 +9.88%

Mid-cap · 372.5 (local)

Why: Quanta Computer surged nearly 10% as Computex 2026 opened in Taipei, amplifying demand expectations for AI server hardware. SpaceX and OpenAI IPO speculation fuelled bets on Asian AI supply chain winners.

Pattern: Thematic momentum breakout — AI server demand is the structural driver. Computex is a recurring catalyst for Taiwan hardware names. The gap-up opening and sustained bid signal strong conviction.

↓ 3711 -1.64%

Mid-cap · 601 (local)

Why: ASE Technology dipped modestly with no firm-specific catalyst — likely mild profit-taking in a packaging/testing name that has run with the broader semiconductor rally in recent weeks.

Pattern: Consolidation pullback in a trending sector — the -1.6% is minor relative to the TAIEX’s strong session and looks like healthy rotation within the semiconductor supply chain, not distribution.

India (NSE)

↑ INFY +4.46%

Mega-cap · 1213 (local)

Why: Infosys rallied 4.5% as Indian IT stocks led the Nifty’s gainers, riding global AI spending enthusiasm and Snowflake’s strong earnings beat which boosted cloud and enterprise tech sentiment worldwide.

Pattern: Sector momentum — Indian IT is a derivative play on global AI/cloud capex. The Nifty IT index surged 3%+, making this a broad sector bid rather than an idiosyncratic move. Trend continuation.

↓ HINDUNILVR -2.39%

Large-cap · 2102 (local)

Why: Hindustan Unilever fell 2.4% as consumer staples underperformed in a session where capital rotated aggressively into IT and tech names — no firm-specific catalyst, just sector rotation drag.

Pattern: Defensive-to-growth rotation — FMCG names are the funding source when IT rallies hard in India. The -2.4% move is mechanical and consistent with a risk-on session, not a fundamental deterioration.

New Zealand (NZX)

↑ MEL +0.51%

Mid-cap · 5.87 (local)

Why: Meridian Energy edged up 0.5% on no clear catalyst — the NZX utility sector was quiet. Likely a steady-state dividend yield bid in a low-volatility name on a quiet session for New Zealand.

Pattern: No pattern signal — the +0.5% is within normal daily noise for a mid-cap utility. NZX tends to trade independently of the broader AP risk-on/risk-off theme given its defensive composition.

↓ FPH -1.27%

Large-cap · 37.29 (local)

Why: Fisher & Paykel Healthcare dipped 1.3% with no firm-specific headline — likely mild profit-taking in a name that has re-rated higher this year on respiratory device demand normalisation.

Pattern: Gentle pullback in a trending healthcare name — the -1.3% is minor and consistent with consolidation. NZX healthcare typically uncorrelated to the AI-driven moves dominating the rest of Asia-Pacific today.

Reading the Session

The exchange-by-exchange breakdown above surfaces both market-specific catalysts and cross-border themes.
