SAN FRANCISCO (MarketWatch) -- Tech stocks closed mostly higher Tuesday, but the session was highlighted by several big losses, including double-digit percentage declines from Lexmark International Inc., Tellabs Inc. and Unisys Corp.

Lexmark (LXK) gave up $10.01 a share, or 21%, to fall to $37.71. The printing and imaging-technology firm reported a third-quarter net profit of $72 million, or 90 cents a share, up sharply from the year-ago period. Excluding one-time items, Lexmark said it would have earned $1.09 a share to easily top Thomson Reuters-compiled consensus of 98 cents a share.

Lexmark also said quarterly sales rose 6.4% to $1.02 billion -- a figure short of the $1.04 billion consensus.

Separately, Lexmark said Paul Curlander would retire as chief executive and be replaced by executive vice president Paul Rooke. See more on Lexmark's results and CEO succession.
