But it sure works like a charm.
In the days of Old Joe Kennedy, they used a news ticker-tape and a few paid leaflet distributors to start rumours that would be traded on, making JPK and his employers alot of money because of their pre-positioning.
Today, the same thing is done much faster and on a global scale. And it still works like a charm.
This week's versions are Alcoa, AMR, and GM/Chrysler. The rumours of their buyouts or mergers may only last a few hours, but that is long enough for millions (dozens, scores, hundreds???) of dollars to be made.
And Wall Street is bitching about Sarbanes-Oxley?
BULLSHIT !!!
