Don't put too much weight on what stocks did after hours following comments from Federal Reserve Chairman Ben Bernanke that called for quantitative easing "for the foreseeable future," StockMonster's Guy Adami said Wednesday.
"I wouldn't necessarily trust this 11-point move to the upside in the S&P," he said. "I mean, say what you want about him, but in terms of the market he's done everything exactly right, seeing the spike here."
The big question, Adami added, was whether stocks would see "a big reversal or carry through" when the market opens.
"Just be a little bit careful here tomorrow," he added.
Bernanke, who spoke at a conference sponsored by the National Bureau of Economic Research, said that the U.S. economy continued to need a highly accommodative monetary policy.
The CNBC's "Fast Money" traders shared how they were planning to play the market following Bernanke's remarks.
RiskReversal.com's Dan Nathan said that the market had already priced in news that had not materialized.
"In a lot of ways people have gotten very comfortable with the notion that the Fed was going to be buying less bonds at some point in the next six months," he said.
Nathan noted the move lower for the U.S. dollar.
"I think you have to be really careful if you want to go in tomorrow and you think it's all clear and buy that opening because if you do have that reversal, it could get nasty," he said, alluding to downturns on May 22 and in June based on Bernanke's comments.
Karen Finerman of Metropolitan Capital Advisors noted that aside from Bernanke's comments, minutes of the Federal Open Market Committee released earlier in the day were less sanguine.
"If you look at earlier comments today from the minutes, there was all kinds of murkiness," she said. "You had a lot of different, more dissenting opinions, I think, than you normally have."

Finerman also noted that gold prices were moving higher, which suggested cautiousness.
"I would not jump in on the open tomorrow and just buy stocks," she said.
