ABN AMRO Bank N.V. analyst Kenneth Leon said weakness in Motorola Inc.'s shares over the past few weeks represents a buying opportunity, and restated a "buy" rating and a 12-month price target of $43 per share. Leon expects Motorola to meet his second-quarter earnings estimate of 23 cents per share. He said the company should also show sequential improvement in handset margins. "We believe the company does not have any problems with production, parts or customers in regard to the new phones. Motorola is aggressively rolling out new handsets that more profitably serve the low-end market," Leon wrote. Motorola shares have been sluggish, dropping from $37.56 June 5 to $30 June 26.
