U.S. stocks dropped Friday morning, with the Dow Jones Industrial Average briefly tumbling more than 100 points, as global fears mount over the eurozone's confrontation with Greece, with a key meeting in progress. The tense deliberations are igniting concerns about a possible Greek exit from the 19-member eurozone

The Nasdaq Composite fell 9.78 points, or 0.20 percent, to 4,914.94.

EU Meets To Discuss Greece's Bailout Deal

Germany surprised the global financial markets Thursday when it rejected the Greek government’s request for a six-month assistance package, rather than a six-month extension of its current bailout program, which would come with austerity and reform conditions that the new Greek government rejects.

The decision comes as time is running out on Greece's current bailout program, which expires Feb. 28. However, newly elected Prime Minister Alexis Tsipras said Friday he is "certain" eurozone finance ministers will accept the deal.

"I feel certain that the Greek letter for a six-month extension of the loan agreement with the conditionalities that accompany it will be accepted,” Tsipras said in a statement to Reuters.

“Factory output growth ticked higher for a second successive month in February, suggesting the goods-producing sector is on course to make a robust contribution to the economy in the first quarter,” Chris Williamson, chief economist at Markit, said in a statement Friday.
