The net loss in the quarter ended Jan. 31 narrowed to $159 million, or $1.50 a share, from $358 million, or $3.37, a year earlier, Hoffman Estates-based Sears said today. Revenue declined 24 percent, to $8.1 billion from $10.59 billion, after the sale of most of stake in its Canadian unit, the spinoff of Lands' End, and the closure of more Kmart and Sears stores. That helped trim costs and expenses to $8.23 billion, from $10.73 billion last year. Sears stock was down 6.5 percent in early trading this morning.
