He sees dip-buyers scooping up less equities by the week, as Joe believes bulls are waiting for trade deal catalysts. In the bond market, Cooper Howard tells investors to brace for choppiness. He sees treasuries moving higher while the FOMC juggles a "labor market bonanza" with JOLTS and other labor prints this week.
