Retail sales and industrial production in April both enjoyed continued growth, reinforcing the sustainability of the economic recovery in the United States. On Friday the U.S. Commerce Department reported retail sales gained 0.4% in April, ahead of Wall Street’s expected 0.2% rise, but below the 2.1% jump in March. Peter Newland, economist at Barclays Capital, notes that the total was driven by a 0.5% increase in both autos and gasoline, and a 6.9% jump in building material sales. All of that is nice, but core sales, which exclude these elements, actually fell 0.2%, which is much weaker than excepted.
