Despite Friday's sell-off and the bearish remarks made by billionaires Carl Icahn and George Soros, Jim Cramer said he is "more constructive than most" on the market.

"I just think, when you look at the overall profile of the earnings that we've been getting of late … they're pretty good, but I recognized we've been up a lot, and it's been very benign. We need to shake out some of the weaker hands," Cramer said Friday on "Squawk on the Street."
