Tractor Supply Co. said Thursday it is raising its quarterly dividend by 15%, to 31 cents a share from 27 cents a share. The rural lifestyle retailer's new dividend will be payable June 12 to shareholders of record on May 29. At Wednesday's stock closing price of $66.69, the new annual dividend rate implies a dividend yield of 1.86%, compared with the SPDR S&P Retail ETF's yield of 1.56% and the implied dividend yield for the S&P 500 of 1.95%, according to FactSet. "For the eighth consecutive year, we are pleased to increase the dividend as we look to return cash to our shareholders," said Chairman Cynthia Jamison. The stock, which is still inactive in premarket trade, has slumped 10.8% year to date, while the retail ETF has inched up less than 0.1% and the S&P 500 has edged up 0.9%.
