US stock futures hovered around the flatline on Friday, following a lackluster session the previous day and a volatile week poised to end with modest gains of 0.3% for the S&P 500 and 1.1% for the Nasdaq, while the Dow Jones is set to close 0.9% lower. Traders remained cautious amid the ongoing federal government shutdown and a lack of fresh economic data, while awaiting new catalysts. Still, attention turns to the release of preliminary Michigan consumer sentiment figures later today. The earnings season is also set to ramp up next week. On the corporate front, Qualcomm shares fell about 1.5% in premarket trading after reports of an antitrust probe in China, while Intel gained 2% following the announcement of its new Panther Lake processors. Among megacaps, Nvidia (+0.6%), Meta (+0.2%), Broadcom (+0.4%), and Tesla (+0.3%) advanced, while Microsoft and Alphabet were little changed. Apple (-0.2%) and Amazon (-0.2%) traded slightly lower.
