US stocks dip on worries about Greece

Wall Street stocks dipped Thursday, following leading eurozone equity markets lower on worries about a potential Greek exit from the trading bloc.

At the closing bell, the Dow Jones Industrial Average was at 18,127.02, down 35.97 points (0.20 percent).

The broad-based S&P 500 shed 2.54 (0.12 percent) to 2,120.94, while the tech-rich Nasdaq Composite Index lost 8.62 (0.17 percent) at 5,097.98, retreating from Wednesday's record.

Frankfurt's DAX 30 index fell 0.79 percent and the CAC 40 in Paris lost 0.86 percent as the tense standoff between Greece and its creditors hung over a meeting finance ministers from the Group of Seven leading industrialised nations.

International Monetary Fund chief Christine Lagarde warned of the potential for a Greek exit of the eurozone and said such a scenario would not be "a walk in the park" for the single currency area.

Analysts also noted that the Shanghai Composite Index fell 6.5 percent on worries about tighter margin requirements in Chinese markets.
