“Tomorrow’s NFP report is very, very important,” said Douglas Cote, chief market strategist at Voya Investment Management. “The ADP report yesterday was very strong, corporate earnings were very strong, so we are in a positive fundamental backdrop for the economy, for corporations, for employment.”
