Piper Jaffray upgraded Tractor Supply to Overweight ahead of the company's Q2 results and raised its price target for shares to $116 from $88. The quarter benefited from a "strong" season in riding and zero turn mowers, and Tractor's earnings are positioned to accelerate through at least 2016, Piper tells investors.
