In this episode, Brian Portnoy sits down with Barry Ritholtz to explain why humans aren't built to be good investors. Portnoy has held senior investment roles throughout the hedge fund and mutual fund industries. He is also the author of the bestselling books, 'The Geometry of Wealth' and 'The Investors Paradox.'
