In 'What's Ahead on Wall Street' for Wednesday Feb. 17, we expect to get more quarterly results on tap as earnings season continues. In the morning, we'll get results from T-Mobile (TMUS), The Priceline Group (PCLN), and Dr. Pepper Snapple (DPS). Then in the afternoon, we'll hear from Jack-in-the-Box (JACK) and Marriott International (MAR). T-Mobile will be one of the companies in focus as both its top and bottom line are expected to grow. For the latest quarter, analysts are looking for profits of $0.15 a share on revenue of a little over $8 billion. Earlier this month, the company said it added 2.1 million customers in the fourth quarter. These strong numbers and its 4G LTE network expansion will likely be key drivers, analyst said. On the economic calendar, we get housing starts and the producer price index for the month of January in the morning, followed by industrial production also for January and minutes from the Federal Open Market Committee from its previous gathering.
