Signet Jewelers Ltd. (NYSE:SIG) attributed its strong sales growth to a higher amount of purchases at its Kay and Jared stores in the United States. During the quarter, same-store sales in the U.S. rose 4.9%, but its smaller U.K. business posted a decline of 1.9%, due to lower store traffic and more purchases of discounted, lower-margin products at its H. Samuel, Ernest Jones and Leslie Davis stores. Ernest Jones notably posted strong sales of Rolex watches at certain locations, leading analysts to suggest that increasing the availability of Rolex watches could have boosted its disappointing U.K. sales numbers. In fiscal 2014, Signet intends to concentrate on its strengths by adding 65 to 75 new stores in the U.S. by the end of the year. Its $57 million acquisition of Ultra, the fifth largest jewelry chain in the United States, will also help Signet ramp up the pressure on domestic competitors.
