Stock of the Day – SuperValu Inc (NYSE:SVU)

National grocery chain Supervalu reports its fourth-quarter results today. Like the rest of the industry, the third largest grocer in the US has relied heavily on promotions to lure shoppers, which has come at the expense of already thin profit margins, notes Bloomberg Business Week. Ahead of the results, its shares have risen 25% since early March and during this time long only investors who lend have added 8 million shares to their holding which now stand at 69 million shares. Yet some investors remain skeptical. Short interest is high and has increased slightly since March to 43 million shares or 21% of the total shares outstanding on loan. This represents half the supply that is available to be borrowed.
