About This Summary

The S&P 500’s nine-week winning streak is threatened as investors pull back from the artificial-intelligence rally.
Broadcom’s lukewarm revenue guidance caused a 13% slump in the stock, wiping out $286 billion in market cap.
Other AI-linked stocks such as Lumentum and Dell see declines.

Investors have been slamming the brakes on the artificial-intelligence rally and that has put the S&P 500’s run of weekly gains under threat.

Futures tracking the index were down 0.4% on Friday. The S&P 500 has risen less than 0.1% since the opening bell Monday, so it’s likely to snap a nine-week winning streak if it closes in the red.

Chip makers have powered the market to record highs but investors have been ditching them ever since Broadcom

AVGO\ \ -12.59% issued so-so revenue guidance late Wednesday.

Shares in Broadcom dropped 1.3% ahead of Friday’s opening bell, having slumped 13% the previous session in a selloff that wiped out $286 billion in market value. Among other semiconductor stocks, Advanced Micro Devices slid 2.2%, Micron Technology

MU\ \ -7.74% declined 2.5%, Nvidia NVDA\ \ +1.94% dipped 1.1%, and Taiwan Semi TSM\ \ +1.88% retreated 1.7%.

Other AI-linked stocks also were struggling. Optical products manufacturer Lumentum dropped 3.5%, while server makers Dell Technologies and Super Micro Computer Inc. fell 2.8% and 2.6%, respectively.

These stocks also were making moves in premarket trading:

QNT\ \ +0.63% fell 2.3% after the quantum-computing company’s trading debut fell flat on Thursday, following a highly anticipated initial public offering.

Coinbase Global and Robinhood Markets declined 0.7% and Strategy dropped 1.4% as Bitcoin and other cryptocurrencies extended a recent selloff.
