Struggling department store chain JC Penney has said it is "pleased" with its performance for the Christmas holiday period.

The US retailer, which has been striving to turn its fortunes amid widening third-quarter losses in November, said its turnaround efforts are continuing to show progress.

"Customers responded well to the company's offerings this holiday shopping season, both in store and online," the company said.

JC Penney also reaffirmed its outlook for the fourth quarter.

In November, CEO Mike Ullman said the turnaround of the group was beginning to take hold and that it was making "significant strides toward restoring JC Penney to its rightful place in retail".
