‘Utterly Absurd’ Stock Rally: Pro

A pullback would be healthy for the stock market — and may be overdue, Josh Brown of Fusion Analytics said Friday.

"I have no idea why we're rooting against a correction," he said. "It's utterly absurd."

On CNBC's "Fast Money," Brown took a long-term perspective.

"It's only the third time in history that we've gone from January into May 1 without a 5 percent correction.," he said. "The other two times, you didn't get a great result afterward. I really don't see why we don't want that cleansing breath of fresh air."

Brian Kelly of Shelter Harbor Capital was bearish.

"History is on my side, and I'm still selling," he said. "I mean, it's uncanny this rally. Everything that I thought would happen – where the economy weakens, you get bad earnings – happened. And the stock market hasn't gone down."

Kelly sounded a note of caution for investors.

"Clearly there's another dynamic going on where individuals are putting money to work in the stock market to get that yield, to get some kind of return because there's no other alternative," he said. "To me, those are very weak hands, and it's a very scary trade."

Dan Nathan of RiskReversal.com called out a warning sign.

"This week, we saw names like Bristol-Myers, Amgen, Procter & Gamble, AT&T – these are all defensives with pretty decent yields that have been pretty crowded trades – they all got nailed," he said. "I think you have to keep your eyes open."

Nathan added that one defensive stock could be a harbinger.

"You can say, 'For every Procter, I know a Johnson & Johnson,' or something like that. But let me tell you something: If we do get that 3, 5, 7 percent selloff in the next couple of months, this could be the canary in the coalmine."
