The shares of the company's larger rivals Nike NKE.N, Dick's Sporting Goods DKS.N and Under Armour fell between 2% and 4% in premarket trade. Aug 23 (Reuters) - Shares of Foot Locker FL.N cratered over 30% in premarket trading on Wednesday, and dragged down those of its rivals, after the retailer lowered its annual forecasts as it reels from weaker consumer demand in the face of still-high inflation. The athletic-wear retailer also missed expectations for quarterly sales, said it would pause its dividend payouts and flagged softer demand in July, which is typically when back-to-school shopping starts.
