Ok! I have an opinion about Martin Armstrong. I'll keep it short and sweet:
His short term & mid term forecasts are pretty much useless in my book.
His macro understanding of how money flows internationally is very good.
I take exception to his insistence that he is the only one who understands cycles in the market.
I subscribed to his service for about a year. His market watch predictions made my head spin and I faced daily bouts of schizophrenia when trying to reconcile his weekly, monthly, and quarterly market indicators.
