Dow Jones Industrial Average futures
 were under pressure on Tuesday as Apple
 shares slid and oil prices rose, while investors braced for the U.S. midterm elections.

Futures tied to the 30-stock average traded 359 points lower, or 0.7%. S&P 500 futures lost 0.1%, and Nasdaq-100 futures
 climbed 0.4%.

Apple shares were down 4%, weighing on Dow futures, after the consumer tech giant rolled out a disappointing margin forecast and iPad sales in the fiscal fourth quarter missed the Street’s estimates.

Conversely, shares of chipmakers bolstered Nasdaq-100 futures as investors moved back into the trade after it saw pressure in the previous session. Micron Technology
 jumped almost 4%, while Advanced Micro Devices
 and Intel
 each rose more than 3%. Additionally, Broadcom
 and Nvidia
 gained around 2%.

Oil prices, meanwhile, moved higher as tensions in the Middle East simmered. Brent crude
 was marginally higher at around $105 per barrel. West Texas Intermediate futures
 advanced nearly 1% to around $97 per barrel.

Stocks are coming off a mixed session. The tech-heavy Nasdaq Composite
 dipped 1.07%, while the S&P 500
 fell 0.51% as investors continued their rotation out of tech stocks. The Dow
 rose about 214 points, or 0.41%.
