With tech earnings continuing to exert pressure on the markets, Wall Street looks set to start Wednesday’s session weaker. Apple’s earnings, despite beating expectations have elicited a negative reaction from the Street, attributable to soft iPhone numbers. Yahoo’s mixed quarterly numbers together with Microsoft’s hefty loss could leave traders a little unsettled. Commodities continue to be weaker, with gold at 5-year lows, even as the dollar has turned mixed. The domestic markets may stay tuned to the earnings flow, existing home sales data and the Greek Parliamentary vote on further austerity measures required for an eventual bailout.
