Nasdaq, SP turn positive for 2010

Stocks jumped Monday, with the Nasdaq and Sp 500 pushing back into positive territory for the year, as investors welcomed AIG's $35 billion asset sale and a pair of mergers in the pharmaceutical sector.

Signs that a Greek bailout package is in the works also came into play.

The Dow Jones industrial average (INDU) gained about 79 points, or 0.8%. The Sp 500 index (SpX) added 11 points, or 1%, and the Nasdaq composite (COMp) jumped 35 points, or 1.6%.

Both the Sp 500 and the Nasdaq ended in positive territory for the year for the first time in over a month.

Stocks rallied Monday, the first day of March, as investors dug back in after last week's retreat. Stocks have been choppy and volatile this year in the aftermath of 2009's big rally.

Stocks jumped last year after trillions of dollars in fiscal and monetary stimulus were injected into the financial system. But optimism about a 2010 economic recovery also fueled the advance.

However, mixed signals about the economy this year have given investors pause as they look for clearer indications that a recovery is not only in place, but can take on a life of its own once the government stimulus fades out.

Concerns that Greece's debt crisis could spread to the rest of Europe and that China is seeking to pull back its expansion all dragged on stocks earlier in the year. But stocks have risen in two of the last three weeks.

There are a few positives today, with some of the deal news, but there's still uncertainty about the economy, said Gary Webb, CEO at Webb Financial Group.

It's going to be a lot more volatile this year, he said. We saw a correction through early February and now we're seeing a rebound. I think we're going to continue to see that seesaw effect throughout this year.

February auto and truck sales are due throughout the day Tuesday. Toyota Motor (TM) is expected to take a hit in the aftermath of its recall of millions of vehicles plagued with safety programs.
