I believe the man is essentially saying that past performance does not indicate future performance. Ironically, most of the comments here are saying he is wrong, because of his past performance.

Can we instead talk about his specific points and why they are wrong instead of just focusing on his past performance?

Also, it looks to me that his performance was good during the great recession. So if another recession is coming, shouldn't the critics here be flocking to him? Or is everyone stuck in the current bull market feedback loop?
