Shares in Swedish mobile phone company

Ericsson

(ERICY)

sank 11% Friday after the company spooked investors when it said its handset division would lose money this year.

Shares finished Friday regular trading down 2 3/4, or 12%, at 19 13/16.

While the company made the announcement as it reported a mostly stellar earnings report, investors clearly keyed on the negative news. While its income before taxes rose 325% for the quarter, to 12.6 billion kroners, its consumer products division did post a loss of 1.8 billion kroners.

According to a company statement, the loss is attributed to "a component shortage from a key supplier and an unfavorable product mix." The company added that to restore profitability it is undergoing a strategic review.
