Session at a Glance

Taiwan’s TAIEX suffers twin mega-drops as US$1.3 trillion AI selloff rips through Asia-Pacific tech.

A brutal week for Asia-Pacific tech after Wall Street’s $1.3 trillion AI selloff spilled across the region. Taiwan bore the heaviest damage — TAIEX posted its third- and sixth-largest point drops on record as TSMC’s 40%+ index weight amplified the contagion. Japan’s Nikkei slid 0.85% as SoftBank cratered on a stalled OpenAI margin loan, though Tokyo Electron bucked the trend on record earnings. Hong Kong’s Hang Seng lost ground with Alibaba dragging after reports of a CNY 2 trillion state-backed data-centre push that threatens private cloud margins.

Defensive rotation was the week’s through-line. Australia’s ASX 200 led gains (+1.36%) as CSL surged on tariff relief hopes, while India’s Nifty 50 rode bank strength higher. Chinese state-owned bank stocks rallied hard — ICBC and Ping An Bank both jumped 5-6% as rock-bottom deposit rates drove a yield hunt into high-dividend SOEs. South Korea split: SK Hynix climbed on Nasdaq listing plans while Hyundai Motor collapsed under tariff costs.

The message was clear — investors rotated out of AI momentum into yield and defensives, punishing concentration risk in tech-heavy indices while rewarding income plays across the region.

Here are the biggest movers across Asia-Pacific’s major exchanges for the week ending Saturday, June 13, grouped by market — each figure is the stock’s move over the full trading week.

Australia (ASX)

↑ CSL +16.11%

Mega-cap · 107.5 (local)

Why: Recovery bounce from oversold levels after May profit warning, supported by confirmation that US pharma tariff carve-outs largely exempt CSL’s plasma-derived therapies from duties.

Pattern: Classic mean-reversion snap from extended downside — stock was trading well below analyst consensus target of A$142, and the tariff clarity removed a key overhang driving forced selling.

↓ NST -5.54%

Mid-cap · 19.26 (local)

Why: Elliott Management publicly pressed Northern Star to reconsider a proposed asset sale, citing valuation concerns — the activist overhang weighed on shares despite firm gold prices.

Pattern: Activist-driven uncertainty typically compresses multiples in the near term — Northern Star’s weekly weakness was idiosyncratic to the Elliott campaign, not gold-sector-wide rotation.

Hong Kong (HKEX)

↑ 2628 +7.57%

Mid-cap · 30.12 (local)

Why: China Life Insurance rallied as part of the broader defensive rotation into high-dividend state-owned financial stocks, with PBoC’s sub-2% deposit rates making insurance yield plays attractive.

Pattern: Momentum continuation within the SOE yield trade — Chinese insurers have been steadily re-rating alongside bank stocks as mainland investors hunt for income above deposit benchmarks.

↓ 9988 -9.87%

Mega-cap · 110.2 (local)

Why: Alibaba dropped nearly 10% after Bloomberg reported Beijing’s CNY 2 trillion data-centre buildout plan, raising fears of state-subsidised pricing pressure on Alibaba Cloud’s private infrastructure.

Pattern: Macro catalyst breakdown — Alibaba’s cloud re-rating thesis hit a wall as government-backed competition threatened margin assumptions, amplified by the broader global AI selloff rotation.

China — Shanghai (SSE)

↑ 601398 +5.99%

Mega-cap · 7.78 (local)

Why: ICBC gained 6% as China’s largest bank continued to attract yield-hungry capital — its roughly 9% dividend yield towers over PBoC’s sub-2% fixed deposit rates, drawing record Southbound flows.

Pattern: Sustained momentum in the SOE dividend trade — ICBC is up 24% year-to-date with no signs of exhaustion as the rate differential between bank dividends and deposits keeps widening.

↓ 601857 -2.17%

Large-cap · 10.38 (local)

Why: PetroChina edged lower as Woodside exercised pre-emption rights to acquire PetroChina’s 10.67% Browse JV stake, signalling a modest asset exit and removing a potential upside catalyst.

Pattern: Mild sector drift rather than a sharp dislocation — the Browse stake sale was small relative to PetroChina’s overall portfolio, and the move stayed within normal weekly volatility range.

China — Shenzhen (SZSE)

↑ 000001 +5.74%

Mid-cap · 11.24 (local)

Why: Ping An Bank rose nearly 6% alongside the broader Chinese banking sector rally, benefiting from the same yield-hunt rotation as ICBC as investors flee low deposit rates for dividend income.

Pattern: Sector-wide momentum lift — Ping An Bank’s move was correlated with the entire A-share banking complex rather than stock-specific news, fitting the defensive rotation theme across Asia.

↓ 002415 -3.32%

Mid-cap · 30.24 (local)

Why: Hikvision drifted lower with no single catalyst — the surveillance-tech giant was caught in the broader tech risk-off as the global AI selloff dampened sentiment across Chinese hardware names.

Pattern: Passive sector drag rather than fundamental deterioration — Hikvision’s 3.3% decline was moderate relative to peers, suggesting no forced selling but a general de-risking of tech exposure.

Japan (TSE)

↑ 8035 +14.38%

Mid-cap · 6.8e+04 (local)

Why: Tokyo Electron surged 14% after posting record quarterly earnings — EPS beat estimates by 21% on booming HBM and advanced logic demand — plus the Teradyne AI chip-testing partnership added fuel.

Pattern: Fundamental breakout confirmed by earnings — Tokyo Electron decoupled from the broader tech selloff because its results validated the capex cycle thesis, making it a relative-strength leader.

↓ 9984 -12.85%

Mega-cap · 6472 (local)

Why: SoftBank cratered 13% after reports that its $6 billion OpenAI margin loan stalled because banks struggled to value unlisted AI equity — compounding the global tech selloff pressure.

Pattern: Momentum breakdown on a stock-specific catalyst layered onto a macro headwind — the margin-loan snag undermined SoftBank’s leveraged-AI-bet narrative at exactly the wrong moment.

Singapore (SGX)

↑ C38U +3.08%

Mid-cap · 2.34 (local)

Why: CapitaLand Integrated Commercial Trust gained 3% as the defensive rotation into yield assets extended to Singapore REITs, with the trust’s stable rental income attracting risk-off capital.

Pattern: Defensive bid in a risk-off week — Singapore REITs acted as a safe harbour while tech-heavy indices sold off, fitting the broader Asia-Pacific yield-over-growth rotation pattern.

↓ O39 -1.84%

Large-cap · 23.5 (local)

Why: OCBC Bank dipped modestly with no single catalyst — the slight weakness reflected general caution across Southeast Asian financials as elevated US yields pressured regional rate expectations.

Pattern: Low-conviction drift within normal range — OCBC’s 1.8% decline barely registers as a signal, more noise than directional thesis in a week dominated by tech volatility elsewhere.

South Korea (KOSPI)

↑ 000660 +3.86%

Large-cap · 2.15e+06 (local)

Why: SK Hynix gained 4% after confirming it chose Nasdaq for its planned US listing targeting August 2026, potentially raising up to $14 billion — the largest foreign semiconductor IPO in years.

Pattern: Catalyst-driven momentum continuation on a stock already up 230% year-to-date — the Nasdaq listing choice de-risks the US market access narrative and broadens the investor base.

↓ 005380 -13.29%

Large-cap · 6.07e+05 (local)

Why: Hyundai Motor plunged 13% as the full weight of US auto tariffs hit home — Q1 profits had already fallen 24% on roughly KRW 860 billion in tariff costs, and the new 25% EU tariff escalation compounded the pain.

Pattern: Fundamental deterioration accelerated by a policy catalyst — tariff costs are structural, not one-off, and Hyundai’s 80%-US-production pivot by 2030 means years of margin pressure ahead.

Taiwan (TWSE)

↑ 3711 +2.25%

Mid-cap · 590 (local)

Why: ASE Technology gained modestly as the advanced packaging leader held up better than broader TAIEX tech during the AI selloff, supported by strong demand outlook for its CoWoS and chiplet services.

Pattern: Relative outperformance in a down-tape — ASE’s smaller decline versus TAIEX peers like Hon Hai and MediaTek suggests the market is differentiating packaging picks-and-shovels from pure AI momentum.

↓ 2317 -8.44%

Large-cap · 260.5 (local)

Why: Hon Hai dropped 8.4% as the AI server maker fell sharply in TAIEX’s twin mega-selloffs — the stock had hit an all-time high of NT$314 on June 3, making it a natural profit-taking target.

Pattern: Technical retracement from a blow-off top — the pullback from all-time highs was amplified by TAIEX concentration risk and correlated with the $1.3 trillion global AI unwind.

India (NSE)

↑ ICICIBANK +6.24%

Large-cap · 1341 (local)

Why: ICICI Bank rallied 6.2% as India’s largest private-sector lender benefited from the defensive rotation into quality financials, with Nifty’s broader 1.1% gain led by banking heavyweights.

Pattern: Sector leadership in a risk-off environment — Indian private banks attracted flows as a domestic-demand proxy insulated from the global tech selloff hitting export-oriented Asian markets.

↓ WIPRO -9.19%

Large-cap · 180.1 (local)

Why: Wipro plunged 9% to a six-year low as post-buyback selling accelerated — investors who bought for the June 5 record date exited en masse, compounded by weak Q1 guidance of 1.5-3.5% sequential revenue decline.

Pattern: Buyback-driven technical unwind layered onto fundamental weakness — the artificial buying support evaporated overnight, exposing genuine demand erosion in Wipro’s IT services pipeline.

New Zealand (NZX)

↑ FPH +6.11%

Large-cap · 39.45 (local)

Why: Fisher & Paykel Healthcare gained 6% as the respiratory device maker benefited from defensive healthcare rotation and continued strong demand for its hospital hardware across Asia-Pacific markets.

Pattern: Defensive bid in a risk-off week — healthcare names with recurring revenue attracted capital fleeing tech volatility, and FPH’s export earnings provide a natural NZD-weakness hedge.

↓ AIR -1.18%

Large-cap · 0.42 (local)

Why: Air New Zealand slipped 1.2% with no single catalyst — the modest decline reflected general caution in travel-exposed names as elevated fuel costs and a softer NZD weighed on airline margins.

Pattern: Low-conviction drift within noise range — the 1.2% move is barely distinguishable from normal weekly volatility for a mid-cap carrier with thin NZX liquidity.

Reading the Week

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.
