Lionbridge Technologies (LIOX) surged after the company was upgraded to outperform from market perform by Piper Jaffray. The firm also lifted its price target to $10 from $7.

"With the recent acquisition of Bowne's globalization business," the report said, "[the company] has emerged as by far the largest player in the globalization industry."

Oplink Communications (OPLK) slumped after the provider of networking components and subsystems was downgraded to neutral from buy at Merriman Curhan Ford.
