m.: Recession signals are 'coming home to roost', Evercore ISI says Signs of a recession are starting to pile up, according to Evercore ISI Chairman Ed Hyman. "With the soft employment report, the NASDAQ correction, the plunge in bond yields, and the plunge in commodity prices, it's possible we're seeing recession signals coming home to roost," Hyman wrote in a Sunday note.

His comments came after the U.S. government reported employment growth that was well below economist expectations on Friday.

That report sent equities tumbling, with the Nasdaq Composite closing in a correction — down more than 10% below. The data also led to some on the Street to increase their odds for a 0.5 percentag.
