"The consensus ... out there is that the worst is over, when it comes to what was driving market down in the first place (credit crisis, subprime, etc.)," said Nadav Baum, managing director at BPU Investment Group in Pittsburgh.

Still, not everyone was convinced that the worst is over.
"On the floor, there's a feeling that the consumer may have hit a wall about three weeks ago," Art Cashin, director of floor operations at UBS, told CNBC.

"If oil stays where it is, it's got to damp consumer spending," Baum said. "But markets don't make mistakes. ... So, if the market is digesting all of this and saying 'the worst is over' then, obviously, the market thinks oil's got to come back down," he added.
