The athletic gear retailer posted a surprise loss in the latest quarter sending shares sharply lower. Instead of the expected profit, it was hit with an adjusted loss of two cents a share. Sales came in at $396 million, a little bit above expectations. Stores open for at least a year saw their sales rise a little more than 4%. But Chief Executive Officer Glenn Lyon said too many retailers are offering too many discounts and the environment is competitive. In response, Finish Line plans to change its spending habits and implement leaner operations.
