Wall Street on edge this morning on word European creditors have rejected Greece's proposal aimed at extending its credit. Stocks (^GSPC) are falling on renewed fears a deal won't be worked out, possibly forcing the country out of the Euro Zone.

Yahoo Finance's Aaron Task says investors don't like this unsettled situation at all.

"It was not greeted warmly by the markets," he points out. "There's still that risk Greece is going to default, Greece is going to leave the Euro Zone. There would be a lot of uncertainty related to that."

Also on U.S. investors' minds today -- the final revision of first quarter GDP. The Commerce Department reporting the economy declined 0.2%, better than the previous reading of -0.7% but in line with estimates.

Task doesn't believe this data will do anything to change any big-picture economic thinking.

"The economy contracted in the first quarter, I think everybody knew that," he points out. "Some more recent economic data suggest that maybe it really was just the weather, the West Coast port strike, and the economy is going to get back on its feet in the second quarter."
