Kohl's surged 8 in Wednesday morning's trading after unexpectedly reporting a profit and reiterating its full-year guidance. The struggling retailer has faced the challenge of proving its brand's appeal to shoppers and achieving consistent sales growth. To win back customers and attract new ones, Kohl's has made various changes, including opening more Sephora shops, expanding merchandise categories, and featuring gift-giving items. The company reaffirmed its full-year outlook, expecting a decline of 2 to 4 in net sales and earnings per share ranging from $2.10 to $2.70, excluding nonrecurring charges.
