Analyst: Tractor Supply is grand, but too dear

Nomura analyst Aram Rubinson had plenty of really nice words for Tractor Supply Tuesday, showering the company with praise and saying its future is really bright. But Rubinson also said the market is well aware of that growth potential and has pushed up the company's shares (Ticker: TSCO) to a level where he can no longer recommend investors buy more.

TSCO is rapidly becoming one of the premier merchants in retailing. Opportunity remains abundant for TSCO. We continue to see room for comps and margins to expand. We believe comps can sustain 4-5% growth, comprised of 1-2% from new stores ramping, 1-2% from inflation and 1-2% from innovation.
