Periodicals are in the business of maximizing sales of each issue.
If the latest issue of Forbes, BusinessWeek, Barron's, or any financial news magazine features a cover story decrying company XYZ, it could very well mean that the worst is over for the shares. In contrast, an article touting the benefits of a particular company or fund could imply that it is overloved. When the story is reaching such a broad base of the reading public, it is likely old news. That is, by the time a story has become so mainstream that it lands on the cover of a major news publication, everyone who will be taking investment action based upon the news will likely act very soon. The news itself will quickly become outdated if not erroneous.
