Disappointing outlooks from computer maker Gateway Inc. and media giant AOL Time Warner Inc. kept a lid on the market.

Personal computer maker Gateway tumbled $2.56 to $7.69. The company said again it would to return to profitability in the fourth quarter before taxes and charges, but forecast revenue below expectations. Analysts said the firm is losing market share to competitors.

AOL Time Warner lost 68 cents to $32. The world's largest media and Internet company said it would take an accounting charge of up to $60 billion, likely the largest corporate charge on record, and reined in forecasts of earnings growth, citing the weak economy.

"The near-term corporate earnings announcements that are coming up are not going to be great news, so it's a little early to see a sustainable rally."
