S&P 500, Nasdaq rise as tech stocks gain ahead of midterm results

What happened

The S&P 500 and Nasdaq rose as tech stocks gained before US midterm election results. Apple fell 2.2% after warning of rising memory chip costs. Nvidia climbed 3%, the Philadelphia chips index jumped 3%, and AMD gained 5.1%. The Nasdaq-100 confirmed a correction, closing over 10% below its all-time high.

Confirmed

Global impact / market context

Tech stock gains show investors still favor chip makers despite worries about heavy AI spending. Apple's warning means higher memory chip costs could squeeze its profit per sale, a sign that component costs can pressure company earnings and holiday revenue plans.

Analyst inference

The Nasdaq-100's correction reflects investor caution about Big Tech's AI spending without clear returns. Falling oil prices offered support, while the Dow fell as other indexes rose, showing uneven investor positioning across sectors ahead of midterm results and chip earnings.

Analyst inference

What to watch

1. Watch Apple's holiday-quarter profit per sale after its warning that rising memory chip costs will continue to pressure results, and how investors react to that pressure. Confirmed
2. Watch AMD's quarterly earnings due after the bell, and whether results justify its 5.1% gain ahead of the report and support the chip sector's rally. Confirmed
3. Watch whether the Nasdaq-100 correction deepens if AI spending worries persist, which could prompt investors to reduce positions in Big Tech stocks and chip makers. Analyst inference
