Online search company AskJeeves.com, which is dependent on ad revenue, saw its stock tumble 60 percent today.
The drop came a day after Yahoo set a new stock low, largely due to fears of a softening online advertising market.
Ask Jeeves shares closed at $3.81, a dive of $5.88.
The fall came after Ask Jeeves said it expects to report fourth-quarter revenue of about $25 million, down from estimates of $36 million. The company expects a loss of 50 cents a share.
