0936 ET - Burlington Stores is positioned to sustain its market-share gains, Jefferies analysts say. Early-quarter sales tracked toward the high end of expectations for the retailer, analysts say. Management has remained conservative through this, given the high bar of comparison with last year's performance, they say. Executives do still see opportunity for margin leverage through disciplined merchandising, inventory management and value, the analysts say. The analysts expect Burlington's second-quarter earnings will be strong and gain most of investors' focus, as shareholders are also looking to learn more about quarter-to-date trends and third-quarter guidance.
