How will Wall Street react to the elections? The general consensus is that Wall Street will react more favorably if the Republican candidate for president wins the election.
The republican candidate has stated that the will do everything in their power to eliminate as many regulations as possible. Since Wall Street represents Corporations, Corporations are very much in favor of just about as much deregulation as possible. Wall Street views democratic candidates of too restricting commerce which reduces profit and makes it harder for Corporations to satisfy their shareholders.
This may be more true in the short and medium term and less true in the long term. A powerful argument can be made that excessive deregulation has created more problems and busts in certain sectors than has helped Corporations in the long run.
