Wall Street stocks Tuesday opened lower as talks between the eurozone and Greece stumbled over efforts to avert a Greek debt default.
Five minutes into trade, the Dow Jones Industrial Average was at 17,966.76, down 52.59 points (0.29 percent).
The broad-based S&P 500 fell 5.59 (0.27 percent) to 2,091.40, while the tech-rich Nasdaq Composite Index shed 9.35 (0.19 percent) to 4,884.49.
Lengthy talks between Greece and eurozone ministers over restructuring the country's bailout broke down. Eurogroup head Jeroen Dijsselbloem on Monday gave Athens 48 hours to request the extension to the bailout program that expires at the end of the month, a demand that Athens bitterly refuses.
