U.S. stocks surged on Thursday, with the Dow Jones Industrial Average marking its best session this year, as Wall Street embraced a drop in applications for jobless benefits as indicative of an improving U.S. labor market and economy, a day ahead of the monthly jobs report.
"It's the absence of bad news," Kate Warne, investment strategist at Edward Jones, said of Thursday's rally.
"What we've seen over the last week or so is the market looking for direction, and then we had worries about emerging markets and slowing U.S. growth, so the knee-jerk reaction was to sell and ask questions later. Now there are indications that the job number may not be as bad as people were fearing so emotions are calming down," she added.
"If you look at U.S. markets in the last week or two, it's really not justifiable based on U.S. fundamentals. Claims coming down is part of that story, it suggests again that maybe the economic story is just fine in the U.S.; we'll find out tomorrow," said David Kelly, chief market strategist, J.P. Morgan Funds, referring to 2014 declines that have the S&P 500 on track for a fourth weekly loss.
Technical levels seemingly played into Thursday's rally as well. The fact that the S&P 500 on Wednesday closed above 1,750, "that was an important level to hold for bulls, and gave us some momentum going into today," said JJ Kinahan, chief strategist at TD Ameritrade.
"The market was heavily oversold. you tried for two days to have a credible rebound and this is the first one you've seen. This is a combination of short covering and the buy the dippers," said Art Cashin, director of floor operations at UBS.

Talk from European Central Bank President Mario Draghi helped push up the euro, with one trader saying the 'risk on' trade started after Draghi's comments boosted the currency, which jumped after Draghi said there was no deflation problem.
"The risk on trade is going on a little bit here. Our market is ripping higher. It's an oversold bounce for sure. You look at the 10-year and it's not dislocating to the downside that much. It's a little weaker….I'd be more willing to trade this rally if the 10-year was at 2.75," said one trader. "You're adding on the dip ahead of a very big number."
