Wall Street has lousy day

Stocks were down sharply from the get-go - just too much concern about debt, both in the U.S. and around the world (the situation in Greece appears to be deteriorating again). Dow finished down 151 points. The only decent news came after the closing bell, with Alcoa CEO Klaus Kleinfeld saying that "demand for aluminum continues to rise and so does growth in our major markets." But the company reported only mixed results for the second quarter, with earnings per share missing analysts' estimates and revenues beating expectations. Alcoa is considered an early bellwether for earnings season, so we'll see how analysts dissect the numbers.
