Session at a Glance

KOSPI plunges 5.7% as AI chip selloff deepens, dragging Nikkei and Taiwan into broad Asia-Pacific rout.

Asia-Pacific markets sold off hard on Thursday after Wall Street’s worst session in months — the S&P 500 fell 1.2% and the Nasdaq 100 lost 1.9% overnight as AI valuations came under renewed scrutiny. Treasury Secretary Scott Bessent’s warning of potential sanctions on Chinese AI firms over alleged model distillation added a fresh geopolitical layer, hitting Hong Kong-listed tech names.

South Korea bore the brunt: the KOSPI cratered 5.7%, extending its brutal July drawdown to roughly 23% from its June peak as leveraged ETF unwinding and foreign selling compounded the AI chip reassessment. SoftBank dragged the Nikkei down 2.7%, while Taiwan’s TAIEX fell 2.7% on semiconductor supply-chain sympathy. Hyundai Motor’s Q2 earnings miss rippled through Korean autos.

Defensive pockets held up — Australian banks, Singapore’s DBS, and Japanese pharma names posted modest gains as investors rotated out of high-beta tech into quality yield. PetroChina edged higher in Shanghai as oil-related geopolitical risk kept energy bid.

Here are the standout movers across Asia-Pacific’s major exchanges for the session of Friday, July 24, grouped by market.

Australia (ASX)

↑ NAB +1.46%

Large-cap · 40.39 (local)

Why: No clear catalyst — NAB outperformed a weak ASX session as investors rotated into high-dividend big-four banks amid the broader risk-off move away from growth and tech.

Pattern: Classic defensive rotation pattern — bank stocks acting as a hide during tech-led selloffs. Move is sector-wide rather than NAB-specific, consistent with yield-seeking flows on risk-off days.

↓ NST -3.91%

Mid-cap · 19.93 (local)

Why: No major company-specific headlines — Northern Star fell alongside a broader pullback in gold equities despite gold holding near highs, suggesting profit-taking in the ASX gold sector.

Pattern: Gold miners often sell off harder than bullion on risk-off days as equity correlation overwhelms the commodity hedge. Watch for mean-reversion if gold spot stays firm into next week.

Hong Kong (HKEX)

↑ 0939 +0.46%

Large-cap · 8.78 (local)

Why: China Construction Bank held up as a defensive play — state-owned bank stocks attracted capital as investors fled tech and growth names hammered by the Bessent sanctions overhang.

Pattern: State-owned financials acting as a safe haven within a falling Hang Seng is a recurring pattern during geopolitical flare-ups. Relative strength here reflects sector rotation, not a fundamental re-rating.

↓ 9988 -4.26%

Mega-cap · 110 (local)

Why: Alibaba fell sharply after Treasury Secretary Bessent warned of potential sanctions on Chinese AI firms over alleged model distillation, with Alibaba’s Qwen unit specifically named in IP theft allegations.

Pattern: Geopolitical headline risk layered onto an already stretched AI valuation correction. This is event-driven rather than technical — watch for further policy escalation as the key variable, not chart levels.

China — Shanghai (SSE)

↑ 601857 +1.38%

Large-cap · 11.03 (local)

Why: PetroChina edged higher as Middle East geopolitical tensions kept crude bid, and state-owned energy names attracted defensive flows amid the broader tech-led selloff in Chinese equities.

Pattern: Energy outperforming tech on a risk-off day is a textbook sector rotation pattern. PetroChina’s low beta and state-owned status make it a natural hiding spot when growth names are under pressure.

↓ 600030 -2.34%

Mid-cap · 27.95 (local)

Why: CITIC Securities fell as brokerage stocks tracked the broader Shanghai selloff — lower trading volumes and risk-off sentiment weigh on securities firms whose revenue is tied to market activity.

Pattern: Brokerages are high-beta plays on market sentiment — they amplify both rallies and selloffs. The 2.3% drop tracks the Shanghai Composite’s 1.6% decline with typical leverage, consistent with sector beta.

China — Shenzhen (SZSE)

↑ 000001 +0.18%

Mid-cap · 11.1 (local)

Why: Ping An Bank posted a marginal gain, holding flat while the broader Shenzhen index fell — large-cap state-adjacent banks attracted mild defensive flows amid the tech-led risk-off session.

Pattern: Near-zero move on a down day signals relative strength via rotation rather than any fundamental catalyst. Bank stocks in China often decouple from tech selloffs given their dividend yield floor.

↓ 300059 -4.34%

Mid-cap · 19.4 (local)

Why: East Money Information dropped as fintech and online brokerage names sold off — the stock is highly correlated with retail trading sentiment, which turned sharply negative across Chinese markets.

Pattern: East Money is a momentum-amplifier that tracks retail activity. The 4.3% drop on a 1.6% index decline is consistent with its historical beta. Watch for further downside if KOSPI-style margin calls spread.

Japan (TSE)

↑ 4519 +2.83%

Mid-cap · 7416 (local)

Why: Chugai Pharmaceutical rose as a defensive pharma play — healthcare names attracted capital as investors fled semiconductor and AI-exposed stocks dragging the Nikkei lower.

Pattern: Pharma outperformance on tech-risk-off days is a well-established rotation pattern on the TSE. Chugai’s Roche parentage adds a foreign-currency earnings floor that appeals during yen volatility.

↓ 9984 -7.06%

Mega-cap · 5500 (local)

Why: SoftBank plunged 7% as the global AI valuation reassessment hit its Vision Fund portfolio hardest — the stock has shed roughly 24% in July as investors question peak-AI pricing across its holdings.

Pattern: SoftBank is the Nikkei’s highest-beta AI proxy. The 7% drop versus the index’s 2.7% reflects its leveraged exposure to the theme. This is momentum continuation to the downside — no mean-reversion signal yet.

Singapore (SGX)

↑ D05 +0.48%

Mega-cap · 73.85 (local)

Why: DBS Group edged higher as Southeast Asia’s largest bank benefited from defensive rotation — Singapore banks offer high dividend yields and low AI exposure, attracting flows on risk-off days.

Pattern: DBS holding green on a red regional tape is a quality-yield rotation signal. The Straits Times Index’s minimal 0.1% decline versus KOSPI’s 5.7% highlights Singapore as a relative haven in the AP complex.

↓ C38U -1.61%

Mid-cap · 2.44 (local)

Why: CapitaLand Integrated Commercial Trust fell as REITs came under pressure — rising rate expectations and risk-off sentiment weighed on yield-sensitive real estate names across the region.

Pattern: REIT underperformance versus banks on a risk-off day suggests rate sensitivity is dominating the yield trade. The 1.6% drop is outsized versus the STI’s flat close, flagging sector-specific pressure.

South Korea (KOSPI)

↓ 000270 -12.88%

Mid-cap · 1.305e+05 (local)

Why: Kia Corporation cratered nearly 13% after sister company Hyundai Motor reported a 21% drop in Q2 operating profit, missing forecasts due to supply disruptions and rising raw material costs.

Pattern: Earnings-miss contagion within a corporate group compounded by the KOSPI’s broader margin-call-driven liquidation. The 13% single-day drop on a group-level catalyst suggests forced selling, not just repricing.

Taiwan (TWSE)

↓ 3711 -5.55%

Mid-cap · 613 (local)

Why: ASE Technology fell 5.5% as the AI chip selloff rippled through Taiwan’s semiconductor supply chain — packaging and testing firms are high-beta plays on the same AI capex cycle under reassessment.

Pattern: Semiconductor supply-chain sympathy selling mirrors the KOSPI and Nikkei tech weakness. ASE’s drop tracks the TAIEX’s 2.7% decline at roughly 2x beta, consistent with its chip-cycle leverage.

India (NSE)

↑ WIPRO +1.38%

Large-cap · 177.2 (local)

Why: Wipro gained as Indian IT services names outperformed — the sector benefits from a weaker rupee boosting export earnings, and IT services are less exposed to the AI hardware valuation reset.

Pattern: Indian IT as a defensive play during global tech hardware selloffs is a recurring pattern. Wipro’s gain while broader Nifty dipped 0.3% reflects sector-specific inflows rather than a company catalyst.

↓ BAJFINANCE -2.52%

Mid-cap · 1014 (local)

Why: Bajaj Finance fell as Indian NBFCs (non-bank financial companies) tracked broader risk-off sentiment — no company-specific catalyst, but financials with higher valuations faced selling pressure.

Pattern: Bajaj Finance trades at a premium multiple among Indian financials, making it vulnerable to de-rating on risk-off days. The 2.5% drop versus Nifty’s 0.3% dip reflects its higher-beta profile.

New Zealand (NZX)

↑ SPK +0.27%

Mid-cap · 1.875 (local)

Why: No clear catalyst — Spark New Zealand posted a marginal gain as telecom utilities attracted mild defensive flows on the NZX during the regional risk-off session.

Pattern: Telecom stocks acting as a safe haven on selloff days is a classic low-beta pattern. The near-flat move reflects NZX’s low correlation to the AI chip theme driving losses elsewhere in Asia.

↓ FPH -1.20%

Large-cap · 39.42 (local)

Why: Fisher & Paykel Healthcare dipped on general risk-off sentiment — no company-specific headlines, but the stock’s premium valuation makes it sensitive to broad market de-risking days.

Pattern: FPH trades at a growth premium on the NZX, making it the index’s closest analogue to global growth de-rating. The 1.2% drop is modest and tracks the regional tone rather than any fundamental shift.

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.
