Stock futures wavered before Monday's session as the escalating conflict between Israel and Iran spiked oil prices and raised investors' concerns about the global economy. Dow Jones Industrial Average futures shed 56 points, or 0.1%. S&P 500 futures lost 0.1%, while Nasdaq 100 futures traded around their flatline.

The Middle East conflict is impacting a wide range of sectors besides the obvious oil and defense names, as a surge in oil prices can affect consumer behavior in many ways.
