This is why math rules!!
Found this nice mathematical model (through an article on infowars.com) that can be used to predict market crashes. Russian economist Nikolai Kondratiev had this theory that economies as well as many other things behave like waves. His model predicted the 1929 incident and some people say that it has predicted a commodity price crash beginning in (yes you know it
....) 2008.
Have a look:
