Wall Street Tech Rout Hits Asian Equities
On Friday, November 6, 2026, the Hang Seng Index (HK50) fell 0.7%, shedding 181 points to settle at 24,612. The decline pulled back a portion of Thursday's massive 3.7% rally (an 877-point surge to 24,797), which had marked the benchmark's strongest single-day performance in 21 months.
The immediate catalyst was a severe repricing across Western technology benchmarks that spilled directly into Asian trading hours. In New York, heightened scrutiny surrounding artificial intelligence regulation combined with growing skepticism over heavy capital expenditures in data centers and semiconductor infrastructure. That environment triggered a 5.5% plunge in the Nasdaq Composite and a 12.2% crash in the Philadelphia Semiconductor Index, erasing trillions of dollars in equity value overnight.
When Asian markets opened, institutional desks moved swiftly to take profits following Thursday's advance. At PropFirmScan, our analysis shows that sharp cross-market sell-offs severely test risk limits for funded accounts, particularly when navigating challenge requirements during high-volatility events.
AI Supply Chain Bottlenecks Weight on Local Tech
Underlying fundamental pressures exacerbated the global spillover. Regional sentiment was dampened by reports that approximately 600,000 Nvidia H200 AI processors were currently held in Hong Kong, awaiting official shipment approval from regulators in Beijing before delivery to mainland firms.
This supply chain friction, paired with broader chip industry concerns, caused sharp declines across Hong Kong's tech sector. Z.AI Co. tumbled 11.8%, while Kingboard Laminates lost 10.1%. AI developer MiniMax slid 9.9%, semiconductor maker SMIC dropped 4.5%, and industry leader Tencent fell 1.8%. This marked a complete reversal from Thursday's gainers, where Tencent had jumped 4.9%, Xiaomi added 4.0%, Meituan gained 5.6%, and Alibaba rose 2.6%.
For traders analyzing these moves, reviewing institutional order flow data helps distinguish temporary profit-taking from multi-session distributive trends. Grounding strategy decisions in rigorous fundamental analysis remains vital when macro tech sentiment shifts rapidly across global trading desks.
Broad Policy Backdrop Fails to Halt Tech Slide
Thursday's major equity rally had been driven by improving global macro factors, including Brent crude falling more than 8% to below US$95 per barrel, lower US Treasury yields, and a weaker US dollar following the US midterm elections. On the domestic front, Beijing's market-stabilization measures had provided significant liquidity, with state-backed funds directing roughly US$11.5 billion into nine ETFs and company applications for PBOC-backed
