It's incredible that this story had such a dramatic effect on UAL. This suggests a strategy:

  1. Plant bad stories about large companies.
  2. Buy put options and wait.
  3. Profit!

This is nothing new; it happens all the time, though usually with smaller companies. It's quite illegal, of course.

In the trade this is known as "Short and distort" You can probably guess how "pump and dump" works now right?
