Re: FW: Random walk

The last paragraph of your memo clearly defined the faulty logic behind the
"random walk" hypothesis.

Just because the chart of some randomly generated numerical series may LOOK like
a chart of stock price movement doesn't mean that they both have identical
CAUSES.  But you're right when you say we can imagine anything.  The theorists
have.

And then they compound the problem by saying "If you believe otherwise, prove me
wrong."  Which, again, is another faulty logic sequence, because nobody can
prove a negative.

The "theory" began in the business schools, not in the departments where logic
is taught.  They would have laughed at the idea as one which could only been
promulgated by a freshman student from an inner city school.

One professor, with the more than appropriate initials of BM, realized that he
could make quite a reputation for himself, and not incidentially a lot of money
also, promoted the idea for his own benefit, but now, even he, is being forced
to try to "adapt" his original thesis.

What I've never been able to understand is why any one who believes this is even
remotely interested in investing their hard earned dollars.
