Halliburton, McDonald's, Apple in focus

U.S. stock futures tilted south on Monday as global markets grappled with uncertainty over the policies of U.S. President Donald Trump and concerns he'll pursue a protectionist agenda as well as mixed quarterly results.

Thirty-four S&P 500 components are scheduled to report results this week, including Halliburton Co, McDonald's Corp and Yahoo Inc. on Monday. Of the 54 companies that have reported so far, 74% are beating earnings estimates by a median of 5%, according to Fundstrat.

Dow Jones Industrial Average futures futures fell 19 points to 19,727, while S&P 500 futures slipped 4 points to 2,262. Nasdaq-100 futures eased 7.5 points to 5,050.75.

"Investors will not only be watching for continued signs of improving sales and earnings, but also will closely analyze just what management teams are saying about their outlook for their businesses under the new administration," wrote Andrew Adams, market strategist at Raymond James in emailed notes.
