Shares of

Embarcadero Technologies

(EMBT)

were among technology's losers Tuesday, sliding 18% after the software company cut its first-quarter estimates.

The company now sees earnings, excluding items, of about 4 cents a share. The company previously predicted it would earn 6 cents to 8 cents a share. Embarcadero lowered its revenue projection to $14.2 million to $14.5 million from an earlier range of $15.1 million to $15.8 million. Analysts polled by Thomson First Call forecast earnings of 7 cents a share on revenue of $15.5 million. "We are disappointed by the revenue shortfall, as the opportunity was there to achieve our objectives," the company said. "Unfortunately, we suffered

from weak results in Europe and our domestic telesales business was affected by lower sales volumes." Shares were trading down $1.39 to $6.21.

Nokia

(NOK) - Get Report

rose 5% after the cell phone maker said the first-quarter average selling prices for its handsets were better than expected.

Previously, Nokia predicted that prices would be flat to sequentially down from the fourth quarter. Shares were up $1.00 to $21.40.

Shares of

Avocent

(AVCT)

fell 7% after the computer parts maker offered a mixed outlook. The company sees first-quarter revenue of $94 million to $95 million, below analysts' projections of $99.9 million. "Our sales were slightly dampened by the normal customer hesitation resulting from a major acquisition and the time spent by both sales forces in planning the Cyclades integration," the company said. Avocent also said a large customer rescheduled more than $2 million in orders. Originally, the customer was supposed to get the order as a one-time shipment. Instead, the company will now receive the order in phases and over a longer period of time.

For the second quarter, though, Avocent sees revenue of $114 million to $118 million. Analysts project revenue of $108.8 million. "We are excited about the progress made to date integrating the Cyclades acquisition and about the expected customer response to our combined product offerings," the company said. Shares were trading down $2.24 to $30.93.

Despite warning that first-quarter sales would fall short of expectations, shares of
