Wall Street wants to see a shakeout that would narrow the field of candidates and shift the dialogue to important issues affecting the economy and taxes, after Wednesday's Republican presidential debate on CNBC.

"I'm looking forward to this debate because the first two were mostly insults and generalities. I think this one is going to get more specific on tax reform," said Greg Valliere, chief global strategist with Horizon Investments.

The main debate is at 8 p.m. ET Wednesday, and features the 10 candidates who have received more than 3 percent in a group of national polls. The field has shifted just ahead of that debate, with a new national poll showing Ben Carson moving up, and Donald Trump losing the lead, for the first time in months.
