$JPM TD Ameritrade senior trading specialist Shawn Cruz said JPMorgan’s strong loan book is a positive indicator for the overall U.S. economy. "One of the best leading indicators of economic performance is expansion of credit. That’s positive for the banks and the economy in general,” he said. Cruz said there’s no reason for Wells Fargo investors to panic. “They did have a few issues with some write-downs and a few troubled spots in their loan book, but in general it looks like business is trucking along."
