The market will rally next week if the Republicans take back the Senate during the midterm elections Nov. 4, and two sectors in particular will benefit, ConvergEx Group chief market strategist Nick Colas told CNBC Thursday.

Of the 186 market participants surveyed, 90 percent believed energy would benefit and 88 percent thought financials would.
