According to stock index futures as of 8 a.m. EDT, the Dow Jones Industrial Average (^DJI 0.56%) will open significantly higher this morning, rising by 108 points at the opening bell.

Microsoft (MSFT -1.27%) is in a hurry to find a new leader.

Microsoft is in the middle of a huge strategic shift, which makes its succession plans critical information for prospective investors. The stock is up 0.8% in premarket trading.

McDonald's (MCD 0.37%) has a new head of its German operations. Reuters reports that the division's chief operating officer will take over for the current CEO at the end of next month.
