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. The price tag represents a 14% premium to BindView's closing price of $3.50 on Friday. The deal is expected to close during the first quarter of 2006.

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.

Shares of Affiliated Computer Services ( ACS) fell 6% after the company announced the resignation of its chief executive officer. The information-technology outsourcing company said Jeff Rich, who served as CEO since 1999, would be leaving to pursue other business ventures. Mark King, who most recently served as president and chief operating officer, will replace Rich. "I have met the objectives I set for myself, and ACS, during my tenure as CEO and it's time to move on to new opportunities and challenges," Rich said in a statement.
