S&P 500, Nasdaq edge higher ahead of midterm results; Apple falls

What happened

The S&P 500 and Nasdaq rose as oil prices fell ahead of US midterm election results. Apple dropped 2% after warning higher memory chip costs would pressure its holiday-quarter gross margin, which means the profit kept per sale.

Confirmed

Global impact / market context

Apple's warning links rising chip costs to thinner profit per sale, a cost pressure that can spread to other device makers. Falling oil prices lower fuel and transport costs for companies, supporting profits and helping explain why chip stocks and the broader market gained.

Analyst inference

Investors are weighing midterm election results, falling oil prices, and mixed earnings. Apple's margin warning hurt its shares, while Nvidia and other chip stocks gained. Software stocks like Gartner fell sharply, showing investors are shifting money toward chips and away from software.

Analyst inference

What to watch

1. Apple said memory chip costs would keep rising, pressuring its holiday-quarter gross margin, which means profit per sale. Watch whether other device makers face the same cost pressure. Confirmed
2. Watch whether oil prices keep falling as investors monitor a possible US-Iran peace deal, since cheaper fuel lowers transport and production costs for companies and can support profits. Proposed
3. Watch chip stocks like Nvidia and AMD, which gained ahead of AMD's earnings due after the bell, since results could signal whether demand stays strong enough to offset rising memory costs. Analyst inference
