stock markets and 9/11

Stumbled upon a very interesting piece of news today.....
http://www.propagandamatrix.com/articles/august2007/270807_market_crash.htm.
Allegedly someone is betting a lot of money (almost a billion USD) on a stock market crash within the next month. A more interesting bit of information from the article was that similar activities were observed a few days before 9/11.

I'm not sure of the authenticity of any of these information. They might just be another angle to 9/11 conspiracy theories. But sure enough, makes for interesting reading.
