The Nasdaq powered to a fresh record Thursday, easily topping the prior all-time high in a broad rally that withstood signs that a Greek debt default could be moving closer.

At the closing bell, the tech-rich Nasdaq Composite was at 5,132.95, up 68.07 points (1.34 percent), more than 25 points above the May 27 record close. The Dow Jones Industrial Average jumped 178.43 (0.99 percent) to 18,114.17, while the broad-based S&P 500 gained 20.51 (0.98 percent) at 2,120.95.
