- China and Hong Kong led Asia higher yesterday — Shenzhen surged 2.44% and Hang Seng gained 1.34% — but a sharp US tech selloff overnight clouds the open
- US Technology sector dropped 2.47% as AI chip stocks pulled back, setting up pressure on Asian semiconductor and tech names at Wednesday's open
- Copper fell 2.34% overnight, a headwind for ASX 200 miners after Australia already closed lower yesterday
Where Asia Closed Yesterday
China dominated Tuesday’s session. The Shenzhen Component jumped 2.44% to 14,704, the Shanghai Composite climbed 1.41% to 3,983, and the Hang Seng rose 1.34% to 25,453. That kind of broad-based mainland strength — with Shenzhen outpacing Shanghai by a full percentage point — typically signals risk appetite flowing into growth and tech-weighted names rather than state-owned defensives.
Japan followed the bid higher. The Nikkei 225 gained 0.74% to 69,220, supported by export-sensitive sectors as USD/JPY held firm above 160. South Korea’s KOSPI surged 2.42% to 6,978 in its most recent session, though that close dates to Friday August 14 ahead of a market holiday — traders will be watching for catch-up positioning when Seoul reopens.
The outliers sat on the other side of the ledger. Australia’s ASX 200 slipped 0.46% to 9,073, weighed down by materials and resources names. India’s Nifty 50 edged lower by 0.32% to 24,288. New Zealand’s NZX 50 bucked the trend with a 1.30% rally to 13,900 in Wednesday’s early session.
US Overnight Snapshot
Wall Street handed Asia a mixed signal. The S&P 500 fell 0.69% to 7,690 while the Nasdaq Composite dropped 1.33% to 26,300, dragged lower by a concentrated tech selloff. The Technology sector (XLK) was the worst performer at -2.47%, with AI chip stocks like Micron pulling back after an extended run — headlines flagged the unwind as a classic momentum-crowding reversion.
The Russell 2000 lost 1.26%, suggesting the selling wasn’t confined to mega-cap tech. But sector rotation was real: Financials gained 0.45% and Energy rallied 1.76%, keeping the damage to the broader index relatively contained. The VIX ticked up 4.28% to 15.8 — elevated from recent lows but still well below the 20 threshold that signals genuine stress.
For Asia, the Nasdaq drawdown matters most. HKEX-listed tech and Taiwan’s semiconductor heavyweights will feel the gravity of a 2.47% XLK decline at the open. Japanese chip equipment makers face the same headwind.
Commodity + FX Watch
Copper fell 2.34% overnight to $6.45 — the sharpest move across the commodity complex and a direct read-through for ASX 200 miners like BHP and Rio Tinto at Wednesday’s open. Gold eased 0.68% to $4,390, pulling back from recent highs without breaking trend. WTI oil was essentially flat at $84.40, offering no new signal for energy-heavy indices.
On the currency side, AUD/USD edged up 0.32% to 0.711, providing a modest offset to the copper drag on Australian equities. USD/JPY held above 160 with a 0.15% gain — that persistent yen weakness continues to support Japanese exporter earnings but keeps the intervention risk conversation alive. The dollar’s grind higher will act as a mild headwind for Hong Kong-listed China names priced in HKD.
What to Watch Today
- HKEX and TWSE tech at the open. With US tech down 2.47% and AI chip stocks specifically cited in the pullback, expect Hang Seng Tech and TSMC to gap lower. The question is whether yesterday’s China momentum absorbs the blow or gives way.
- ASX 200 materials sector. Copper’s 2.34% overnight decline lands on top of yesterday’s 0.46% index loss. BHP, Rio Tinto, and Fortescue will set the tone for whether the ASX can hold 9,000.
- China policy follow-through. Shenzhen’s 2.44% surge suggests traders are positioning for continued stimulus signaling. Watch for any PBoC open-market operations or state media commentary that could extend or reverse the move.
- Eli Lilly’s weight-loss pill progress. The European approval headline for LLY’s oral GLP-1 could spill into Asian pharma names with obesity-drug exposure, particularly Japanese and Korean biotech.
Bottom Line
Wednesday’s Asia session opens with a split personality: yesterday’s China-led rally ran hot, but the overnight US tech selloff and copper weakness inject caution at the edges. The most likely outcome is a two-speed session — mainland China and Hong Kong grinding on domestic momentum while tech-heavy markets in Taiwan and Japan absorb the Nasdaq drag. Luna3 sees the balance tilting slightly risk-off for the region overall, with the ASX 200 most exposed to the copper-plus-US-weakness double hit.
