Ciena Tumbles on Wider Losses, Weak Economy

Ciena Corp., a maker of communications-network equipment, tumbled the most in more than three years after reporting a wider-than-projected loss and forecasting lower revenue than analysts had estimated.

Excluding restructuring expenses and other items, the third-quarter loss was 4 cents a share, Linthicum, Maryland-based Ciena said today in a statement. Analysts had estimated a 2-cent loss on average, according to data compiled by Bloomberg. Ciena had an adjusted profit of 8 cents a share a year earlier.
