Wall Street weighed down by tech at the open

US stock indices opened the week lower amid a lack of data from the US, and after Federal Reserve Bank of New York President William Dudley spoke about workforce development at Onondaga Community College, in Syracuse, where he noted that the economy is in "good position" and the Fed will move on with its policy tightening plans. 

Earlier as well, European Central Bank President Mario Draghi pointed in his testimony today about the economy and monetary policy before the European Parliament Economic and Monetary Affairs Committee, in Brussels, to the importance of seeing the impact of economic recovery on the region's inflation, noting that recent economic recovery has gained more momentum and strength on the back of improved regional conditions. 

Apple led the tech sector lower, which in turn weighed on Wall Street, after the giant iPhone maker marked the worst weekly performance since April 2016 with a 5.5% loss, as investors take into consideration the higher price of the new iPhone X, and the supply delays that could weigh on Apple's sales and future profits. 

Later today, Federal Reserve Bank of Chicago President Charles Evans will speak about economic conditions and monetary policy at The Economic Club of Grand Rapids Luncheon Meeting, while Federal Reserve Bank of Minneapolis President Neel Kashkari will speak about the Federal Reserve at a town hall event hosted by the University of North Dakota.
