Given the title of the article, I reckon it's just another piece of noise to invest with fund/ wealth managers..Indexes are by all accounts a fudge imo.
As I said, you can 'design" something based on your desired outcome. 

You can't pick a fund manager before,agree but you can still learn from the practical lessons later and apply them, Lynch lessons are timeless.
