"This whole game of chicken is fraught with risk ... risk for everybody. Risk for the investors, for the consumer, to the economy, to Americans, to Europeans, risk across the board," said Ken Polcari, managing director at ICAP Equities in New York.
Still, analysts ultimately expected a deal by the Aug. 2 deadline. "What the market is telling you is that although it thinks a deal is going to get done, it's going to wait and see what the ultimate deal is to decide whether the market likes it or not," Polcari said. [ID:nN1E76N0EP]
