Will this actually happen??

Answer 1

Probably not. I agree with Wikipedia... "His critics question the assumption that clues to all major stock market events can be found in the relatively short history of well functioning stock markets in the world. His work has also been criticised for heavy use of data dredging- where it is easy to find patterns in past data and assign predictive powers to them when many such patterns occur in every data collection purely by chance."
