Get Your Stock ‘Buy’ List Ready: Pro

There's no reason to buy stocks ahead of this week's employment report, but get ready for a market upturn, Stephen Weiss of Short Hills Capital said Thursday.

"So the best posture right now, people think, and I don't disagree is stay on the sidelines, took a little risk off," he said. "And I've got my 'buy' list, though, because I do believe it turns."

Midday, the S&P 500 and the Dow Jones Industrial Average both broke below their 50-day moving averages.

On CNBC's "Fast Money," Weiss added that there was "too much uncertainty" to be a buyer, from the U.S. Bureau of Labor Statistics report due on Friday, as well as from Europe.

But Weiss also downplayed the decline in the market.

"We haven't seen a huge selloff," he added.

Josh Brown of Fusion Analytics said that there was no reason to be a buyer of stocks here.

"First of all, what's the rush? Most people who are running money are sitting on plus-10 percent returns," he said.

Brown also cited the uncertainty of the upcoming employment report.

"Why would anyone want to make a huge bet in front of that?" he said. "Who needs to, other than people who've been trailing this rally?"

Brown said that a 4 percent correction and failing rallies were expected.

"I actually think that's the responsible stance," he added.
