Tractor Supply Co. (Nasdaq:TSCO) caters to a rural consumer base made up primarily of farm and ranch customers. This focus has lended itself to a unique growth opportunity, which the company has fully exploited in recent years. Its second quarter results reflected its strong growth trajectory, as did increases in its full-year sales and profit outlook. Unfortunately, Tractor Supply’s prospects are no longer a secret, and this is making future returns for shareholders less of a certainty.
