Nvidia shares plunge 4% after CEO Huang resigns amid scandals, dragging Taiwan futures down 784 points

Nvidia's former CEO Jensen Huang resigned amid personal and national security scandals, sending Nvidia shares down over 4% and triggering a 6% plunge in the Philadelphia Semiconductor Index, with Taiwan stock index futures dropping 784 points in overnight trading. US stocks initially rose after October producer prices increased 0.3% month-over-month, below the 0.4% expected, but reversed sharply as semiconductor selling pressure spread. The Nasdaq fell 442 points, while Nvidia dropped below $160 per share, and TSMC ADRs declined 3.1%. The selloff hit Taiwan futures hard, with night session contracts falling 1.79% to 43,055 points, signaling significant downward pressure for Taiwan's stock market when it reopens on Monday.
