The Dow Jones industrial average has been in a slump over the past two weeks as traders saw an escalating risk that Greece could leave the euro, causing more disruptions in markets.

The glitch sent shares of Nasdaq OMX Group Inc., parent company of the Nasdaq market, down 4.4 percent.
Facebook shares were priced at $38 and initially traded as high as $45. They closed at $38.23.
Europe was the bigger worry for investors. The Fitch ratings agency dropped Greece to the lowest possible grade for a country not in default Thursday. Fitch said Greece's departure from the euro "would be probable" if elections next month do not reverse political trends in Greece, which have brought in politicians opposed to the terms of Europe's bailout.
"Despite all the attention on the Facebook IPO, I think there's still lots of underlying uncertainty surrounding this European debt situation," said Scott Wren, senior equity strategist for Wells Fargo Advisors in St. Louis. "This Greek situation isn't good. I think it's going to get worse before it gets better. Probably the same with Spain."
Borrowing costs for Italy rose slightly to 5.76 percent on Friday. The yield on Spain's 10-year bond fell slightly to 6.2 percent, a level that's still very high by historic standards.

"We think Facebook is a little bit of a sideshow. Great company. But maybe one that's valued on the high side of most people's tastes."
