NEW YORK -(Dow Jones)- Applied Magnetics Corp. shares rallied 22% Tuesday, benefiting from the overall strength of the disk-drive sector and what may be a resulting short squeeze. The NYSE-listed shares (APM) closed Tuesday at $12.375, up $2.06, or 20%, on volume of two million shares, more than three times the daily average. Jeff Matthews, of investment firm Ram Partners, said the activity in Applied Magnetics shares may be in part the result of some short-covering. As of March 15, short interest in the stock totaled 10.3 million shares. In selling securities short, investors borrow stock and sell it, betting that the price will fall and that they will be able to repurchase the shares later at a lower price for repayment to the lender. Short interest is the number of shares that haven't been bought for return to lenders. The disk-drive group as a whole is showing surprising resiliency, given the bleak fourth-quarter earnings outlook from Quantum Corp. (QNTM) late Monday. Matthews said investors may be chasing the battered sector in the belief that the worst is over. Officials at Applied Magnetics, a Goleta, Calif., disk-drive parts concern, weren't available to comment. |
