Shares of Foot Locker Inc. soared 16% in premarket trading Monday, after the athletic shoe and gear retailer said it expects to report a surprise fiscal second-quarter profit, as the reopening of stores helped drive a surprise jump in sales.

Excluding non-recurring items, the company expects to report adjusted EPS of 66 cents to 70 cents, while the FactSet consensus was for a per-share loss of 60 cents. The company said same-store sales for the quarter rose about 18%, compared with the FactSet consensus for a decline of 23.6%. “As we continued to reopen stores throughout the quarter, we saw a strong customer response to our assortments, which we believe was aided by pent-up demand and the effect of fiscal stimulus,” said Chief Executive Richard Johnson. “This fueled our in-store sales and also drove continued momentum across our digital channels.” The stock has dropped 29.5% year to date through Friday, while the S&P 500 has gained 3.7%.Market Pulse Stories are Rapid-fire, short news bursts on stocks and markets as they move.
