In "What's Ahead on Wall Street" for Thursday, Feb. 18, there are a few key quarterly reports we're focusing on.

Before the opening bell, we'll hear from Wal-Mart Stores (WMT - Get Report) , DISH Network (DISH - Get Report) , Starwood Hotels & Resorts Worldwide (HOT) , and Discovery Communications (DISCA - Get Report) . In the afternoon, Nordstrom (JWN - Get Report) will reveal its latest results.

Investors will be closely eyeing Starwood Hotels & Resorts Worldwide when the hotel operator posts its latest results. Wall Street is anticipating both its top and bottom line to drop from the same period last year.

For the latest quarter, analysts' are expecting earnings of $0.79 a share on revenue of a little under $1.5 billion. Since more than half of the company's properties are located outside the U.S., foreign exchange numbers will likely dampen its revenue per available room (RevPar).

Last November Marriott International (MAR - Get Report) said it was buying Starwood for $12.2 billion, creating the world's largest hotel company.

TheStreet's Portfolio Analyst Scott Berman is paying attention to Starwood's results. "I think there are two things in the release here," Berman said. "The first is the actual results and the outlook moving forward. We're really going to be paying attention to that RevPar number. It's been pressured in the U.S. and globally, so we're going to be looking for their view and whether the consumer is doing well on that front.

"On the other hand, we're going to be looking for an update on the Marriott deal as the shares of Starwood have really been trading in line with Marriott. So it's important to see how that's progressing."

On the economic calendar, we'll get weekly jobless claims and the Philadelphia Fed business outlook survey in the morning, followed by the weekly oil inventory data.
