Never mind trying to forecast what Federal Reserve Chairman Ben Bernanke is going to do next quarter. Fact-based investing is the best way to play this market, Stephen Weiss of Short Hills Capital said Friday.

"I'm going to stick with the facts. And the facts are: It's an easy-money policy," Weiss said. "The facts are: Despite some spotty data — because nothing goes up in a straight line — the environment's still very, very strong."

On CNBC's "Fast Money," Weill said that he was buying weakness.

"I remain bullish," he said. "Dips will be bought. We're going to reach new highs."

Josh Brown of Ritholtz Wealth Management took a contrary view, citing more uncertainty.

"Look, I've consistently maintained that a taper would actually be positive," he said. "This, I don't know what to make of it."

The run-up in stocks, he added, was a "relief rally."

"But that was not what you want to see intermediate- to longer-term if you're an investor," Brown said. "It's not a bullish thing that the economy's not in great shape."

OptionMonster's Pete Najarian eyed market volatility.

"You got this great reaction just the other day, but you look at the volatility," he said. "It's getting sucked out of the market really rapidly, so people are at least comfortable, I'd say, right now."

Najarian said that the pull-back in stocks was positive, especially interest-rate-sensitive sectors such as housing and financials.

"I think it's healthy," he said. "The fact that we spiked up the way that we did, and now you're giving a little bit of a give-back, now you're starting to look for some of the opportunities on some of the things that spiked too fast. And now you're getting your opportunity again to get in some of these names."
