Third-quarter earnings continue to be a mixed bag, with Lucent and Baidu.com the latest firms to feel investors' wrath for results that weren't quite up to expectations.

Shares of Lucent lost 5.8% Wednesday after the telecom equipment company's sales of $2.43 billion were up only slightly from the year-ago quarter and below what analysts were looking for. Looking ahead, the company forecast 5% growth over the next year, and said it plans to continue to trim jobs, as wireless sales begin to slow.

After the close on Wednesday, Baidu.com tumbled 15% after its first results as a publicly-traded company missed estimates. The two analysts tracking the company expected Baidu to report a profit of four to six cents a share. The company's sales rose 27.6% sequentially to $11 million, but earnings of three cents a share were below forecasts.
