Shares of the big-box retailer fell more than 15% in premarket trading after it also said that its third-quarter profit had halved.
In contrast, Walmart, which dedicates most of its shelf space to groceries and other daily essentials, raised its full-year sales and profit forecast on Tuesday.
However, the top U.S. retailer warned that its customers could slow spending, especially in general merchandise categories, in the holiday quarter.
FedEx (FDX.N) and Amazon (AMZN.O) have also warned of a slump in holiday season demand in recent weeks, while overall U.S. holiday sales are expected to rise at a slower pace this year, according to an industry trade group.
On an adjusted basis, Target's profit was $1.54 per share for the quarter ended Oct. 29, missing analysts' expectations of $2.13.
