Off-topic: Why do these kind of websites always have a stock price next to brand names? Is this useful Information? It looks a little bit scammy.
How anyone would find this to seem scammy I wouldn't understand.
It's an automated parsing script(either client or server side). For mentioned companies that are publicly traded and named in a story, the script looks up their stock listing and adds it and a hyperlink to the story for context. In most cases, though, it's not very helpful. But easier just to have the script run on every story than to do the linking by hand for a few stories.
What's more is that even a few hours to a few days after a story is released, the stock price no longer has any relevance to the story since the widgets are not pegged to that point in time.
