Session at a Glance

KOSPI crashes 5.5% as Broadcom’s AI guidance miss detonates a semiconductor rout across Asia-Pacific.

Broadcom’s after-hours guidance miss — AI chip sales forecast 7% below consensus at $16 billion — sent shockwaves through Asia’s semiconductor complex. South Korea bore the brunt: the KOSPI plunged over 6% intraday, triggering a circuit breaker on KOSPI 200 futures, before closing down 5.54%. Foreign investors dumped ₩4.3 trillion ($3.12 billion) of Korean equities in a single session. SK Hynix fell nearly 10% and Samsung shed over 6%.

The chip contagion spread unevenly. Japan’s Nikkei lost 1.31% as Tokyo Electron cratered 6.6%, while Taiwan’s TAIEX dropped 1.33% with AI-supply-chain names like Delta Electronics hit hard. Hong Kong added its own pain: a regulatory crackdown on mainland Chinese funds flowing into HK investment accounts hammered insurers and banks — AIA, Prudential, HSBC, and StanChart all fell sharply.

Defensive pockets held up. Australia’s CSL rallied nearly 6% on healthcare rotation, Nintendo gained 3.5% in Tokyo, and India’s consumer staples outperformed as investors fled the AI trade for earnings visibility.

Here are the standout movers across Asia-Pacific’s major exchanges for the session of Friday, June 5, grouped by market.

Australia (ASX)

↑ CSL +5.75%

Mega-cap · 97.91 (local)

Why: Classic defensive rotation — investors shifted into healthcare names as the Broadcom-triggered AI selloff punished growth and cyclical stocks across the region.

Pattern: Textbook sector rotation: when semiconductors and tech sell hard on an earnings miss, biotech/pharma mega-caps attract safe-haven flows. Watch for follow-through if chip weakness persists.

↓ MIN -5.08%

Mid-cap · 67.57 (local)

Why: No single catalyst — likely commodity-linked weakness as lithium and iron ore sentiment softened alongside broader risk-off tone in resource-heavy names across the ASX.

Pattern: Mid-cap miner giving back part of a strong 3-month run (+30%) in a risk-off session. Mean-reversion candidate if commodity fundamentals hold, but exposed to further liquidation in a sustained de-risk.

Hong Kong (HKEX)

↑ 0939 +1.99%

Large-cap · 8.72 (local)

Why: China Construction Bank bucked the broader HK selloff — state-owned banks seen as defensive yield plays and potential beneficiaries if mainland deposit flows shift to onshore channels.

Pattern: Counter-trend strength in a down tape often signals institutional rotation into low-beta dividend names. SOE banks tend to outperform when financials face regulatory pressure elsewhere.

↓ 1299 -3.52%

Large-cap · 74 (local)

Why: Hong Kong’s crackdown on mainland Chinese funds flowing into HK investment accounts directly threatens AIA’s cross-border insurance sales channel, which depends on mainland visitors.

Pattern: Regulatory shock catalyst — AIA’s HK insurance model is structurally exposed to mainland capital controls. This is a macro-policy-driven move, not a technical pattern, suggesting more downside if rules tighten further.

China — Shanghai (SSE)

↑ 601988 +2.54%

Mid-cap · 6.05 (local)

Why: Bank of China gained as state-owned bank shares attracted defensive rotation on the mainland — investors favoring high-dividend SOE names amid broader tech and growth weakness.

Pattern: SOE bank momentum continuation — Chinese state banks have been on a multi-month re-rating as ‘dividend yield as bond proxy’ trade persists. Gradual grind higher, not a breakout.

↓ 600900 -0.40%

Large-cap · 27.61 (local)

Why: Yangtze Power dipped modestly with no clear catalyst — the utility giant’s defensive profile limited losses versus growth names, but broad market weakness weighed.

Pattern: Near-flat in a down session is relative strength for a large-cap utility. Consistent with its role as a bond-proxy — low beta, tight daily ranges. Not actionable as a directional signal.

China — Shenzhen (SZSE)

↑ 002415 +2.12%

Mid-cap · 31.28 (local)

Why: Hikvision edged higher — no clear catalyst, but A-share tech names with surveillance and AI-edge exposure sometimes decouple from the US semiconductor narrative on domestic policy hopes.

Pattern: Modest gain in a weak tape suggests accumulation. Hikvision trades on its own domestic cycle (smart city, security spending) rather than the US AI capex story driving today’s selloff.

↓ 300750 -1.27%

Mega-cap · 403 (local)

Why: CATL slipped 1.3% as the broader tech and growth selloff weighed; the battery giant recently overtook peers as the top CSI 300 weight, making it a target for index-tracking outflows.

Pattern: Becoming CSI 300’s top weight (5.3%) makes CATL a high-beta proxy for index flows. When foreign and passive money sells the index, the largest weight absorbs disproportionate pressure.

Japan (TSE)

↑ 7974 +3.47%

Mega-cap · 7524 (local)

Why: Nintendo rallied as a defensive consumer play — gaming and entertainment names attracted rotation away from semiconductor exposure that dominated the Nikkei selloff.

Pattern: Counter-trend strength during a chip-driven index decline. Nintendo’s earnings are uncorrelated with AI capex cycles, making it a natural hiding spot. Watch for continuation if risk-off persists.

↓ 8035 -6.61%

Mid-cap · 5.945e+04 (local)

Why: Tokyo Electron cratered 6.6% as the Broadcom guidance miss directly challenged the AI semiconductor capex narrative — TEL is Japan’s primary proxy for global wafer fab equipment spending.

Pattern: Momentum breakdown: TEL had been riding the AI capex supercycle thesis and is now unwinding on a single-name guidance miss. High-beta semiconductor equipment names amplify index moves in both directions.

Singapore (SGX)

↑ U11 +0.52%

Large-cap · 38.51 (local)

Why: UOB edged up 0.5% as Singapore banks held relatively firm — ASEAN banking is less exposed to the AI semiconductor cycle and benefits from steady regional loan demand.

Pattern: Flat-to-positive in a broad selloff signals defensive positioning. Singapore banks trade on NIM and dividend yield, not tech narratives, giving them low correlation to today’s catalyst.

↓ C6L -1.56%

Mid-cap · 6.94 (local)

Why: Singapore Airlines fell 1.6% on general risk-off sentiment — airlines are high-beta cyclicals that sell alongside travel and consumer discretionary in broad de-risk sessions.

Pattern: Mild pullback in a risk-off session, not an airline-specific catalyst. Reports of Boeing wide-body orders from SIA are forward positive but didn’t offset today’s macro headwind.

South Korea (KOSPI)

↓ 000660 -9.92%

Large-cap · 2.07e+06 (local)

Why: SK Hynix plunged 9.9% as Broadcom’s AI guidance miss triggered a cascade — DRAM/HBM names were the epicenter of the selloff, with foreign investors dumping ₩4.3 trillion of Korean stocks in one session.

Pattern: Crowded-position liquidation: SK Hynix was the most concentrated AI/HBM bet in Asia. Circuit breaker triggered on KOSPI 200 futures. This is forced selling, not fundamental re-rating — but momentum is decisively broken short-term.

Taiwan (TWSE)

↓ 2308 -5.15%

Mid-cap · 2300 (local)

Why: Delta Electronics dropped 5.1% as part of the broad AI supply-chain selloff — Delta supplies power solutions to data centers and is seen as a secondary AI capex beneficiary in the Taiwan market.

Pattern: Sympathy selloff: second-derivative AI plays (power, cooling, connectors) sold harder than TSMC on the Broadcom miss. Amplified beta on the downside when the capex narrative cracks.

India (NSE)

↑ HINDUNILVR +1.54%

Large-cap · 2112 (local)

Why: Hindustan Unilever gained 1.5% as India’s consumer staples sector attracted defensive rotation — FMCG names are classic hiding spots when global tech sells off and India’s domestic demand story is intact.

Pattern: Defensive rotation pattern: large-cap consumer staples in India decouple from global semiconductor narratives. HUL’s move is low-conviction but directionally consistent with risk-off flows into earnings visibility.

↓ WIPRO -3.89%

Large-cap · 196.4 (local)

Why: Wipro fell 3.9% as the global tech selloff hit Indian IT services — sector already facing structural headwinds from sluggish demand and AI-driven automation anxieties, with buyback deadline adding volatility.

Pattern: Indian IT is a high-beta global-tech proxy. Wipro underperforms peers structurally (flat sales growth, weak guidance) so it amplifies sector weakness. The ₹250 buyback at premium may cushion near-term but doesn’t fix the growth problem.

New Zealand (NZX)

↑ AIR +2.41%

Large-cap · 0.425 (local)

Why: Air New Zealand rose 2.4% with no clear catalyst — the stock trades at a deep discount to pre-COVID levels and may be seeing value-buyer interest in a market largely insulated from the semiconductor selloff.

Pattern: Idiosyncratic micro-cap move in a small, domestically oriented market. NZX has minimal semiconductor exposure, so Air NZ decoupled from the regional risk-off theme entirely. Low conviction as a signal.

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.
