Wall Street set for slightly higher open

Wall Street looked set to open slightly higher on Monday after a string of recent economic reports pointed to strength in the U.S. economy. Adding to the sentiment were U.S. Federal Reserve Chair Janet Yellen's comments last week, urging caution on raising rates, given the risks from global economic conditions. Data last week indicating strength in the U.S. labor market and a recovery in the manufacturing sector did little to change expectations for interest rate hikes by the Fed in 2016.
