Where Asia Closed Yesterday

China mainland was the clear winner. The Shenzhen Component surged 2.77% to 14,924.87, its strongest session in weeks, while the Shanghai Composite added 1.36% to 3,967.13. That kind of combined move usually signals renewed domestic fund rotation into growth and tech-heavy Shenzhen boards — worth watching for follow-through today.

Japan and South Korea tracked each other higher: the Nikkei 225 rose 0.74% to 67,743.50 and the KOSPI gained 0.73% to 6,856.83. Both benefited from a weak yen (USD/JPY holding above 162) and steady global risk appetite. Hong Kong’s Hang Seng added 0.52% to 24,340.73, a more measured move that lagged the mainland rally — a gap that often closes over the following sessions.

The outlier was Taiwan. The TAIEX dropped 1.42% to 44,737.95, the region’s worst performer by a wide margin. With TSMC and its supply chain dominating the index, this sell-off lines up directly with the US tech weakness that played out overnight. India’s Nifty 50 also slipped 0.66% to 24,052.05, while Australia’s ASX 200 finished dead flat at 8,808.50. Singapore’s Straits Times edged up 0.46%.

US Overnight Snapshot

The S&P 500 added 0.38% and the Nasdaq Composite gained 0.62%, but the headline numbers masked a sharp rotation underneath. The Nasdaq 100 ETF (QQQ) actually fell 0.27%, and the Technology sector (XLK) dropped 1.11% — meaning mega-cap tech names sold off while breadth improved across smaller stocks. The Russell 2000 climbed 0.43%, confirming the tilt toward value and small caps.

Financials led the session with XLF up 0.68%. The VIX collapsed 5.03% to 15.7, well below the 20 threshold that signals stress. For Asia, the mixed read is this: broad risk appetite is healthy, but the tech rotation will pressure TAIEX and HKEX-listed tech names at the open. Japan exporters and financials sit on the right side of this trade.

Commodity + FX Watch

Oil was the standout, with WTI jumping 1.29% to $80.40 — a tailwind for ASX energy names like Woodside and Santos, and for Petrochina on the mainland. Copper gained 0.78% to $6.38, supporting the ASX materials sector that went nowhere yesterday. Gold was flat at roughly $4,070, up just 0.11%.

The big FX move was the Australian dollar, surging 0.84% to 0.698 against the greenback. A stronger AUD reflects improved commodity sentiment and could lift offshore earnings translation for Australian companies. USD/JPY barely moved at 162, keeping the weak-yen export tailwind intact for Japanese manufacturers. No major CNH shift to disrupt the mainland’s momentum.

What to Watch Today

• TAIEX follow-through: Taiwan shed 1.42% before the US tech sell-off even hit. If QQQ weakness spills into Asia’s session, TSMC and its upstream suppliers face a second day of pressure — watch whether the TAIEX opens below 44,700.
• China mainland momentum: Shenzhen’s 2.77% move demands a test. If volume confirms the bid, this rally has legs beyond a one-session squeeze. Look for ChiNext leadership and whether Hang Seng tech closes the gap to mainland gains.
• SK Hynix debut timing: Headlines flagged a “tough time” for SK Hynix’s Wall Street debut. Any read-through to Samsung Electronics and the broader Korean memory sector could weigh on KOSPI sentiment, particularly if AI-adjacent semiconductor names sell in sympathy with US tech rotation.
• ASX resource open: Oil up 1.29%, copper up 0.78%, AUD up 0.84% — all three point to a positive open for ASX materials and energy. The index was flat yesterday; this commodity setup gives it something to work with.

Bottom Line

The overnight setup leans risk-on for most of Asia, but with a clear sector filter. Anything exposed to US mega-cap tech rotation — Taiwan semis, HKEX-listed tech — faces headwinds, while commodity-linked markets (ASX, mainland resources) and financials get a cleaner bid. The VIX at 15.7 says the broader market isn’t worried; the question Luna3 readers should ask is whether China’s mainland surge was a one-day event or the start of a rotation worth positioning around.
