what happened

According to The Wall Street Journal, energy stocks and oil prices fell the day after the US midterm elections, while consumer shares rallied. On Thursday the pressure intensified: memory-chip makers and data-center related stocks took heavy losses, and semiconductor shares posted their worst decline in more than six years.

Sandisk led the S&P 500's decliners, dropping 22.3% on Thursday. Lumentum fell after accepting a takeover offer that is an all-stock deal from another tech company. The Journal also reports that major investors doubt Anthropic's blockbuster IPO can proceed as planned after an AI-related selloff.

why it matters

The political uncertainty coincided with a tech selloff and the unwinding of AI-related bets, which is why markets reacted broadly. The WSJ notes that volatility may persist, so investors are weighing the risks of concentrated portfolios.
