Investing.com -- U.S. semiconductor stocks slipped in premarket trading on Friday, extending a global technology selloff after Apple raised prices on several of its products, fanning concerns that surging memory chip costs could dampen consumer electronics demand and cloud the outlook for the broader AI trade.

In premarket trading by 04:27 ET (08:27 GMT), On Semiconductor fell as much as 11.6%, Micron slid around 3.5%, and AMD and Intel each dropped about 2.8%. U.S.-listed shares of ASML declined 2.3%, and TSMC lost 1.3%, while Applied Materials and Qualcomm also edged lower.

Apple shares dropped 6.15% on Thursday after the company announced steep price increases on iPads and MacBooks, citing higher costs for memory and storage components. The move erased roughly $250 billion in market value and tempered enthusiasm over a blowout earnings report from Micron, whose shares had surged nearly 16% to a record high.

The tech giant briefly took down its online store early Thursday before relaunching with price increases of roughly 15% to 25% across its Mac and iPad lineups.

The base MacBook Air rose $200 to $1,299, the MacBook Pro climbed $300 to $1,999, and the entry-level MacBook Neo increased $100 to $699. On the iPad side, the Air rose $150 to $749 and the Pro increased $200 to $1,199. iPhone prices were left unchanged, though Apple hinted further increases could be coming.

"Big tech may at some point start to feel the pain of these higher component costs, and that can become a broader ecosystem headwind," said Charu Chanana, chief investment strategist at Saxo, according to Reuters.

"That is why markets are becoming more cautious. Higher input costs, heavier capex needs and rising funding demands are making investors more selective about AI exposure."

Analysts also pointed to month-end and quarter-end rebalancing flows as a contributing factor to the choppiness in large-cap technology names, which have outperformed for much of the second quarter.

The weakness in U.S. premarket trading followed sharp declines across Asian markets. China’s CSI 300 closed 3% lower, the Shanghai Composite fell 2.3%, and Hong Kong’s Hang Seng slid 1.8% to a fresh one-year low, dragged down by AI-related shares.

South Korea’s KOSPI tumbled 5.8%.
