'Fast Money' traders: Stay away from Amazon

Positive long-term on Amazon: Pro

Shares of Amazon.com rallied after posting revenue of $19.7 billion on estimates of $19.4 billion and matching on earnings Thursday. But the "Fast Money" pros wanted to see more out of the company.

OptionMonster co-founder Pete Najarian agreed.

"They've been doing everything they want to do to get the Street to start to like them, but they've got to start earning a lot more money," he said. "They put a lot of money into the whole warehouse thing, they're obviously into the cloud, but the street is starting to digest this now and the stock's not getting a great reaction."

Aaron Kessler of Raymond James echoed the sentiment.

"I still like Amazon long term, but I agree, they do need to start to show some increasing leverage over the next few quarters," he said.

StockMonster's Guy Adami was less than positive.

"I think you take profits here – I'm not saying you short Amazon here," he said. "I'm saying when you got in when we told you to in the last couple weeks, you take profits at these levels."

RiskReversal.com's Dan Nathan is much more wary of Amazon's future as well as the tech sector as a whole.

"This stock went parabolic last year and it had the same issue with spending and margins. Sales are still growing on a massive number at 20 percent, so that's fantastic, but the mood, the investor mood, has changed. And so to me, I think a lot of these stocks that are in these downtrends, they're going to break the lows from earlier this month and you do not want to be buying this dip right now," he said.
