South Korea’s KOSPI exploded nearly 6% higher on Thursday while US tech stumbled into the holiday weekend — and Monday’s Asia open will test whether that momentum carries or the Nasdaq drag catches up.

Where Asia Closed Yesterday

The standout performer was Seoul. KOSPI surged 5.76% to 8,088 — a move that dwarfed every other index in the region and points to either a major short squeeze, policy catalyst, or foreign fund rotation into Korean equities. That kind of single-session gain demands attention at Monday’s open: follow-through would confirm a regime shift, while a giveback would suggest a one-day event.

Japan’s Nikkei 225 added 1.47% to close at 69,744, inching closer to the psychologically significant 70,000 level. The ASX 200 gained 1.37% to 8,844, while Hong Kong’s Hang Seng rose 1.28% to 23,350 — both solid sessions that reflected broad risk appetite across the region.

Mainland China was more measured. The Shanghai Composite edged up 0.37% to 4,044 and the Shenzhen Component gained 0.64%. Singapore’s Straits Times Index added 0.52% to 5,244. Taiwan’s TAIEX was essentially flat at +0.08%, notable given its heavy semiconductor weighting — a warning sign that Thursday’s tech caution was already filtering through before the US session confirmed it.

US Overnight Snapshot

Wall Street came back from the July 4 weekend with a clear rotation trade. The S&P 500 was flat while the Nasdaq Composite dropped 0.80%, and the technology sector ETF (XLK) fell 2.71% — the sharpest sectoral decline of the session. Headlines flagging a potential “violent unwind” in the momentum trade add context: crowded tech positioning may be starting to crack.

The flip side of that rotation was strength in financials (XLF +1.53%) and materials (XLB +1.94%). The VIX at 16.1 suggests markets aren’t panicking — this reads as orderly rebalancing rather than a flight to safety. For Asia, the tech weakness is the transmission mechanism to watch: HKEX-listed tech names and TAIEX semiconductor stocks are the most exposed to overnight Nasdaq sentiment.

Commodity + FX Watch

Gold rallied 2.04% to around $4,200 — a strong bid that reinforces the risk rotation theme and likely reflects some safe-haven demand alongside a softer dollar. Copper also gained 2.04%, which is a direct tailwind for ASX mining heavyweights like BHP and Rio Tinto at Monday’s open.

WTI crude slipped 0.51% to $68.30 despite OPEC+ raising output levels again — a decision that continues to pressure oil prices even as the cartel tries to manage the glut. Energy names across the region may trade cautiously.

AUD/USD firmed 0.33% to 0.694, helped by the copper bid and broad commodity strength. USD/JPY was essentially unchanged at 161, keeping the yen weak but stable — no new catalyst for Japanese exporter repricing in either direction. The steady yen removes one variable from the Nikkei equation, leaving global risk appetite as the primary driver.

What to Watch Today

• KOSPI follow-through: Thursday’s 5.76% surge was exceptional. Monday’s first hour in Seoul will reveal whether institutional buyers are adding or whether this was a one-day squeeze. Watch Samsung Electronics and SK Hynix for direction.
• HKEX and TAIEX tech pressure: US tech’s 2.71% sector decline should weigh on Alibaba, Tencent, and TSMC at the open. Any pre-market ADR weakness in these names will set the tone for their home-listed shares.
• ASX miners on copper strength: With copper up over 2% and materials leading the US rotation, the ASX 200’s resource sector has a clear tailwind. BHP, Rio Tinto, and Fortescue are the names to watch for early buying interest.
• Nikkei 70,000 test: At 69,744, the Nikkei is within striking distance of a round-number milestone. A flat yen and positive Friday close provide a setup — but the tech drag from Nasdaq may limit upside in semiconductor-adjacent names like Tokyo Electron and Advantest.

Bottom Line

Monday’s Asia session opens into a split setup: commodities and cyclicals have the overnight wind at their back, while tech faces a clear headwind from the Nasdaq selloff. The KOSPI’s massive Thursday rally is the wildcard — if Seoul builds on it, risk appetite across the region gets a boost. At Luna3, we read the balance as cautiously constructive for resource-heavy markets like Australia and mildly defensive for tech-heavy boards in Hong Kong and Taiwan.
