Apple's ( AAPL) stock initially took a hit Friday morning after a false report circulated that Steve Jobs had suffered a major heart attack. In an email to TheStreet.com, Apple's vice president of worldwide corporate communications, Katie Cotton, categorically denied the story, which appeared on the iReport Web site. iReport, which publishes "unedited, unfiltered" news posts from members of the public, subsequently removed the story, and Apple's stock bounced back in later trading. By late morning, Apple shares were up 3.4%. The Apple CEO's health has recently come under close scrutiny. Jobs, who battled pancreatic cancer in 2004, appeared thin at the launch of the new iPhone in June, although Apple said he was recovering from "a common bug."
