Intel shares fell more than 20 in premarket trading on Friday after the company reported disappointing earnings results for the second quarter and announced plans to lay off over 15 of its employees. Intel's poor results weighed down other chip stocks as well, with TSMC closing over 4 lower and Samsung falling over 4. In the US, Nvidia dropped around 3.5 in premarket trading due to Intel's news and a separate report that the DOJ has launched an antitrust investigation into the company. The slump in chip stocks added to an overall global market sell-off, especially dragging down the tech-heavy Nasdaq index.
