News that Steve Jobs had suffered a heart attack (which later turned out to be false) pushed the company's stock price to under $100.
Here's a graph of the damage:
Judging by that, I think that a fair few investors developed chest pains as a result. The lowest point there seemed to be $97.45. Stock price has since recovered.
The news story was posted onto CNN's iReport by someone under the nickname of johntw. The story has since been removed.

Steve Jobs was rushed to the ER just a few hours ago after suffering a major heart attack. I have an insider who tells me that paramedics were called after Steve claimed to be suffering from severe chest pains and shortness of breath. My source has opted to remain anonymous, but he is quite reliable. I haven't seen anything about this anywhere else yet, and as of right now, I have no further information, so I thought this would be a good place to start. If anyone else has more information, please share it.
Horse play or a genuine mistake? We may never know.
