US stocks closed mixed after wavering narrowly between gains and losses Thursday, with the S&P 500 hitting a new intraday record of 2,102.13 points, as investors tried to digest the impact of negotiations over Greece's bailout.

The Dow Jones Industrial Average dropped 44.08 points, or 0.24 percent, to 17,985.77. The S&P 500 was down 2.23 points, or 0.11 percent, to 2,097.45. The Nasdaq Composite Index rose 18.34 points, or 0.37 percent, to 4,924.70.

Germany rejected a request from Greece Thursday to extend its loan agreement with eurozone creditors, saying the Greek proposal did not meet previously agreed criteria decided by the Eurogroup Monday.

Earlier on Thursday, Greece submitted a request to the Euro Working Group for a six-month extension of the four-year bailout loan agreement in a bid to receive vital financial aid from the eurozone after the current bailout expires on Feb. 28.

A renewed oil decline also added negative sentiment to the market. According to data from the US Energy Information Administration, US oil stockpiles increased by 7.7 million barrels last week, exceeding market estimates. US oil price slipped below 50 dollars a barrel in morning session before paring part of the losses to settle at over 51 dollars a barrel Thursday.

However, US weekly jobless claims came out positive. In the week ending Feb. 14, the advance figure for seasonally adjusted initial claims decreased 21,000 from the previous week's unrevised level to 283,000, lower than market consensus of 290,000, said US Labor Department Thursday.

Wall Street also continued to digest minutes of the Fed's January policy meeting released Wednesday, which showed that more Fed officials leaned toward keeping rates at zero "for a longer time" than wanted in an earlier move.

In corporate news, shares of Wal-Mart dipped 3.21 percent to 83. 52 dollars apiece Thursday after the world's largest retailer reported adjusted earnings that beat estimates and revenue that missed expectations.

Latest data from Thomson Reuters showed that S&P 500 companies' per-share earnings in the fourth quarter of 2014 are expected to grow 6.6 percent year on year, while revenue growth is forecast to increase 1.9 percent. A total of 425 companies in the S&P 500 have reported quarterly results to date.
