The S&P and Nasdaq turned positive Tuedsday as Ford shares jumped more than 5 percent ahead of the auto maker's sales numbers, due out soon.
The Dow remained slightly lower after a report showed pending-home sales fell much more sharply than expected.
Consumer staples, health care and utilities were the biggest drags. Financials, consumer discretionary and energy advanced.
The dollar declined, while oil and gold were slightly higher.
Pending-home sales tumbled 16 percentin November, much steeper than the 5-percent drop expected and the 3.7-percent gain logged in October. However, sales rose 15.5 percent year over year.
Economists chalked up the droff in pending-home sales to the original expiration of first-time homebuyers' tax credit but expect they'll ramp up again in the first half of 2010 as the tax credit was extended.
The morning's other data point was factory orders, which rose 1.1 percentin November, more than double of what was expected. But what economists — and the market — are waiting for is Friday's jobs report. The buzz in the market is that this could be the first report in two years to show jobs added to payrolls — and that it could be up to 40,000 jobs.
Expectations of a gain are building in the market but Joel Naroff of Naroff Economic Advisors says don't worry if it doesn't happen this Friday.
"The data are pointing to a return to payroll gains not losses and which month it occurs doesn’t matter much," Naroff wrote in a note to clients. "What the economist community is arguing about is how strong those increases will be. I worry that they will not be very robust this year."
Ford shares hit their highest level since 2005 as investors bet the auto maker will post strong sales in the next hour or so, following a report out of China earlier today that Ford's joint venture there saw sales jump nearly 55 percentin 2009.
