Nvidia Tumbles 9% on Leadership Turmoil as Asian Chipmakers and Tech Futures Falter

Nvidia shares plummeted 9% in late US trading on Thursday, November 12, snapping a broader artificial intelligence rally and sending shockwaves through Asian trading floors.

Nasdaq 100 futures sank more than 1%. S&P 500 contracts dropped 0.5%. The abrupt rout tore through semiconductor supply chains from Seoul to Taipei, reversing a 2.3% cash-session rally on Wall Street as institutional desks rushed to hedge exposure.

The sell-off followed emergency board deliberations regarding Chief Executive Officer Jensen Huang. Company directors convened to weigh Huang's future following disclosures that he had maintained a personal relationship with Kimberly Powell, Nvidia's vice president of healthcare, alongside separate scrutiny from US security officials over contacts with a suspected Chinese intelligence operative. Server partners Super Micro Computer and Dell Technologies tumbled in tandem. Yet rival chipmakers Advanced Micro Devices and Broadcom pushed higher, as institutional traders positioned for potential market-share reallocation should Nvidia stumble. Specialized cloud provider CoreWeave surrendered portions of an earlier 25% leap.

Asian Bourses Fragment Across Semiconductor Belts

Trading desks in Asia opened without conviction on Thursday morning.

South Korea’s Kospi slipped 0.068%, dragged down as memory supplier SK Hynix slid and Samsung Electronics surrendered early advances. In Taipei, the TAIEX shed 0.24%, weighed by cautious positioning in Taiwan Semiconductor Manufacturing Co, the primary foundry partner manufacturing Nvidia's high-performance silicon. Hong Kong's Hang Seng futures dropped 0.7%. Japan bucked the regional decline—the Topix gained 0.51% while the Nikkei 225 added 0.17%.

Below is the performance snapshot across key regional equity indicators and energy benchmarks:

Yen Intervention Warnings and Dalal Street Additions

Currency markets generated parallel volatility.

Japan’s chief currency official, Vice Finance Minister for International Affairs Atsushi Mimura, warned market participants against speculative pressures as the Japanese yen hovered near 160 per dollar—the threshold that triggered direct intervention from Tokyo earlier in the year.

Domestic Indian equities braced for a guarded start. The GIFT Nifty signaled a muted opening with a fractional positive bias. Both the benchmark Nifty and the Nifty Bank showed initial signs of momentum fatigue at elevated valuations following multi-session advances, pointing toward short-term consolidation before any renewed upward climb. The banking index remained the central focus for institutional desks, sitting within 400 points of its all-time record high.

Market liquidity in Mumbai will also absorb portfolio adjustments following MSCI's semi-annual index review. The index compiler added four domestic counters to its MSCI Global Standard Index: Life Insurance Corporation of India, Coforge, Adani Green Energy, and Meesho. The inclusions are set to trigger passive foreign institutional inflows across the four companies upon implementation.

Market Context: Global hardware supply chains remain extraordinarily concentrated around Nvidia's graphics processing architecture. Any structural disruption to corporate leadership or regulatory compliance inside the Santa Clara firm immediately reverberates across high-bandwidth memory fabricators in South Korea and foundries in Taiwan, dictating equity pricing across Asian bourses.

In commodities, Brent crude futures stabilized at $92.46 a barrel in early Asian trade following two consecutive sessions of declines. Energy markets tracked geopolitical impasses after a senior Iranian official explicitly rejected proposals to surrender stockpiles of enriched uranium, leaving diplomatic negotiations between Washington and Tehran frozen. Equity and derivatives traders now turn their focus to institutional order flows at the European market open and Nvidia's formal governance updates.
