Stock market may rally Monday on 'Biden bounce,' Keefe Bruyette says

Recent polls suggest that Vice President Joe Biden may have reversed his recent fall in South Carolina and could win a solid victory in the state's primary on Saturday, Brian Gardner of Keefe Bruyette tells investors in a research note titled "Is There a 'Biden Bounce' Coming on Monday?" If Biden wins, the markets might rally on Monday on the view that Senator Bernie Sanders is no longer the clear frontrunner for the Democratic presidential nomination, says the analyst. However, Gardner cautions against overreacting to a possible Biden win. Sanders' path to the nomination might be less certain than a few days ago, but he's still the frontrunner, the analyst says.
