Ryan Payne, president, Payne Capital Management says right now - the mood on Wall Street boils down to one phrase: economic optimism.

"Profits are going up and because of all this stimulus that's out there, all this pent-up demand, the world is going to rock-and-roll. The economy is going to get a lot stronger over the next couple of months. It's going to run red hot. So I think the bottom line is you want to be bullish here. We talked about inflation a lot today and stocks are one of your best inflation hedges."
