Stock futures are little changed after Nasdaq Composite registers worst day since April: Live updates

Stock futures were flat in overnight trading after a selloff in favored technology names brought the Nasdaq Composite to its worst day since April.

Futures tied to the Dow Jones Industrial Average added 31 points, or 0.08%. S&P 500 and Nasdaq-100 hovered near the flatline.

In extended trading, SolarEdge Technologies sank 13% after announcing plans for a $300 million private offering of convertible notes, while Pool Corp dropped 11% after adjusting its guidance downward.

Nvidia sank nearly 7% on Monday, building on a 4% decline from last week. Other connected semiconductor and artificial intelligence names fell, with Super Micro Computer dropping 8.7%. Qualcomm shed 5.5%, while Broadcom declined nearly 4%. Information technology was the worst-performing sector in the broad index as a result, dropping 2.1%.
