Target on Wednesday reported a stronger-than-expected jump in same-store sales and profits for the key fourth quarter, helped by its expanding online business, and it forecast modest earnings growth for this quarter.

The retail giant posted earnings of $1.50 a share, excluding one-time items, on revenue of $21.75 billion. Wall Street expected Target to post earnings of $1.46 per share on $21.63 billion in revenue, according to a consensus estimate from Thomson Reuters.
