Warren Buffett says he is still seeing improvement in the U.S. economy, albeit at a slow pace. “The economy is improving,” Buffett told CNBC. ” I want to emphasize that. Not at a very rapid clip, but this country has done well since 2008, certainly compared to much of the rest of the world.” Buffett also talks about the possibility of the Federal Reserve increasing its bond-buying program, and discusses one of his major holdings, IBM.
