NEW YORK (MarketWatch) -- U.S. stocks turned higher Tuesday, with the S&P 500 hitting an intraday record, after reports emerged that Greece may ask for a six-month extension on its debt obligations.

The newly elected Greek Prime Minister Alexis Tsipras will ask for an extension on the country's loan agreement on Wednesday, reported The Wall Street Journal, citing unnamed officials.

The S&P 500 (SPX) turned up, with five of its 10 main sectors trading higher. Health-care and financial stocks led the gains.

The Dow Jones Industrial Average (DJI) inched higher, leaving half of its 30 members in the red. Microsoft and Cisco Systems led losses, while the Nasdaq Composite Index (RIXF) was slightly higher.

Peter Cardillo, chief market economist at Rockwell Global Capital, noted that the S&P 500 hitting 2,100 is remarkable.

"It was surprising to see earlier losses contained, given the weakness in metal, the dollar and oil. This is part of a larger trend of unwinding of safety trade over the past few days. Money that is coming out of bonds is flowing into stocks, which is why we are at record highs," Cardillo said.

The yield on 10-year Treasury note, which moves inversely to prices, jumped 7 basis points to 2.14% on Tuesday.

Kate Warne, investment strategist at Edward Jones, said the standoff between Greece and European commission had increased uncertainty, resulting in the earlier pullback.

"Over the past week markets have been complacent about Greece and the eventual agreement and any news that deviates from that leads to negative reaction," Warne said.

Commenting on earnings season, Warne said corporations were able to beat lowered-down expectations.

"Earnings were not stellar, but we still saw growth in profits. So, that's a positive for stocks. And while a stronger dollar does slow earnings growth for many companies, it does not stop or decrease it, as companies are adapting to new reality," she added.

Greece is still the focus: Negotiations between the Greek government and eurozone finance ministers ended in a stalemate on Monday, sending jitters around global markets. On Tuesday, news reports emerged that Greece's new antiausterity government is ready to request an extension to its loans but the terms were still unclear. European ministers insist on keeping austerity measures as part of the condition for the extension, while the Greek government sees that as unpalatable.

Greece's current program expires at the end of February.

Data: Tuesday's economic data came in below expectations, but the reaction seems to be mostly muted. The Empire State manufacturing moved slightly lower but remained in positive territory in February.

Meanwhile, a gauge of confidence among home builders fell in February to a four-month low but continued to point to a higher level of construction in the months ahead.

Earnings:Goodyear Tire & Rubber Co.(GT) posted a huge profit jump, thanks to a one-time tax credit that offset currency fluctuation and weaker sales in Europe. Shares jumped.

Starwood Hotels & Resorts Worldwide Inc.(HOT) said Chief Executive Frits van Paasschen has resigned and will temporarily be replaced by director Adam Aron. Shares rose sharply.

Cablevision Systems Corp. (CVC) was the top decliner amid negative analyst comments, including a MoffettNathanson downgrade to neutral from buy for big cable stocks that cited concerns such as cord cutting, according to a report in the Hollywood Reporter.

Other markets: European markets were mostly higher. In Asia, most indexes closed higher, with the Shanghai Composite Index extending its winning streak to seven sessions.

In commodity markets, prices fell across the board despite the weaker dollar. The ICE dollar index (DXY) moved slightly lower. Gold futures fell 1.6% to $1,207.90 an ounce, while oil (CLH5) prices turned flat at $52.72 a barrel.
