Tech stocks moved lower Tuesday, as the market weighed buyout news and earnings reports.

Openwave Systems

( OPWV) tumbled 15.9% after the software company's board rejected an unsolicited tender offer by Harbinger Capital Partners, one of the company's largest shareholders.

Openwave called the offer "inadequate" and "not in the best interests" of the company. "After consultation with Openwave's senior management and its financial advisors, the board believes that implementation of Openwave's stand-alone plan will generate greater value for stockholders than Harbinger's offer," Openwave said in a statement. Shares closed down $1.65 to $8.72.
