New York---US stocks opened lower Friday on renewed worries over a potential Greek debt default as Twitter shares rallied on news chief executive Dick Costolo would step down.
Five minutes into trade, the Dow Jones Industrial Average was at 17,980.09, down 59.09 points (0.33 percent).
The broad-based S&P 500 fell 7.41 (0.35 percent) to 2,101.45, while the tech-rich Nasdaq Composite Index lost 17.17 (0.34 percent) at 5,065.34.
Equity markets in Britain, France and Germany fell sharply after the International Monetary Fund withdrew from talks with Greece, saying a deal was far off.
Twitter gained 3.1 percent after announcing that co-founder Jack Dorsey would step in on an interim basis to lead the microblogging company. Analysts have criticized Costolo for disappointing growth at Twitter.
