Wall Street is on a roll -- for now

Investors are expecting Wall Street to continue its recent winning ways.
Stocks are poised to open higher as investors await March retail sales data and the weekly unemployment report. Markets in Europe and Asia were higher.

Retail sales, though weak, may not be as bad as investors had feared. According to the Wall Street Journal, "Wal-Mart Stores and a select group of its discounting peers have helped retail sales exceed modest expectations every month since December, and that streak likely will continue."
