In "What's Ahead on Wall Street" for the week of March 14, we'll have a mix of earnings reports and economic data.

The week begins with the latest financial results from MannKind (MNKD - Get Report) , followed by DSW (DSW) , Oracle (ORCL - Get Report) and Fogo de Chao (FOGO) on Tuesday.

Midweek, we'll get results from FedEx (FDX - Get Report)  . Towards the end of the week we'll hear from Adobe Systems (ADBE - Get Report) and Tiffany (TIF - Get Report) .

One of the companies investors will be tracking is FedEx. For the latest quarter, Wall Street is looking for earnings of $2.35 a share on revenue of nearly $12.5 billion. Both the top and bottom line are expected to grow year over year. But RBC Capital analysts are cautious due to the higher-than-expected peak season costs.

Benjamin Stoto, director of research for CNBC's "Mad Money," said "I'm really going to be watching how aggressive they were with their share repurchases in the quarter. Their shares got down to about a two and a half year low in late January and early February, and in late January they authorized a new 25 million share repurchase program, which is almost 10% of their shares outstanding. If they were aggressive with that, it could really help the bottom line number."

On the economic calendar, investors will get a read on various markets with the Empire State manufacturing survey, along with the U.S. housing market index on Tuesday. Midweek, we'll get the Federal Open Market Committee meeting announcement. Economists expect the Federal Reserve to leave short-term interest rates unchanged.

And at the end of the week, investors will get the consumer sentiment report.
