Shares of Vitesse Semiconductor ( VTSS) were among technology's losers Monday, falling 9% after the chipmaker cut its fourth-quarter sales forecast.

Vitesse now expects sales of roughly $48 million, down from its previous projection of $52 million to $53 million. Analysts surveyed by Thomson First Call had been expecting sales of $52.7 million. "During the quarter we saw some softness in turns business and delays in the production ramp of our SAS products," the company said. "Additionally, we were unable to obtain all of the required material from our assembly subcontractors in time to ship by the end of the quarter as assembly lead times have lengthened significantly."

Looking ahead, Vitesse expects first-quarter sales of $53 million to $54 million, below the $55.7 million that analysts had been expecting. Shares were trading down 16 cents to $1.71.

BindView Development ( BVEW) rose 11% after the technology-security company agreed to be acquired by Symantec ( SYMC) for about $209 million, or $4 a share, in cash.

Separately, BindView said third-quarter sales would be between $17.7 million and $18.1 million, down from its prior expectation of $19 million to $21 million. Analysts had been expecting sales of $19.5 million. BindView didn't provide a reason for the revision. Shares were trading up 37 cents to $3.87.

"The combination of the two companies' local access networks, which do not overlap, will provide a strong platform allowing for product differentiation and innovation and the delivery of unique packages of service offerings," NTL said. The deal is expected to close during the first quarter of 2006. Shares of Telewest recently traded up 19 cents to $23.14, while shares of NTL fell $1.01, or 2%, to $65.79.

Shares of Applied Digital ( ADSX) rose 15% after the company said its VeriChip subsidiary signed up 49 new hospitals in September to use its VeriMed system for patient identification.

The company previously had expected just 20 to 25 hospitals to adopt the system by the end of 2005. "We are very pleased with the pace of market acceptance in September.
