NEW YORK (AP) — Shares of network equipment providers fell Thursday after a disappointing forecast from Ciena Corp.
Ciena, which makes optical components for telecommunications equipment, saw its shares tumble $3.55, or 19 percent, to $13.17 in late trading. The plunge wiped out two months of gains.
Among other companies, close competitors were the hardest hit. Finisar Corp.'s stock fell $1.34, or 8.7 percent, to $14.07. JDS Uniphase shares fell 61 cents, or 5 percent, to $11.14.
Larger companies affected included Alcatel Lucent SA, down 2 percent, and Ericsson, down 3.5 percent.
On Wednesday morning, Linthicum, Md.-based Ciena reported a wider loss than expected for its fiscal third quarter. The company also said it expects revenue of $455 million to $480 million for its fourth quarter, which was shy of the $500 million analysts expected.
"The tone of the global economy has clearly grown increasingly more cautious over the past couple of months," said CEO Gary Smith. That means its taking longer than expected to reap the benefits of design wins, he added.
