Lars Kroijer joins Owain Bennallack in the Motley Fool studio to talk about “edge”, why you probably haven’t got it, and why that matters. In his former professional life, ex-hedge fund manager Lars hunted for undervalued shares across the globe and devised intricate trades in order to beat the market. But he says most investors should not do anything like that — nor pay managers to try to do so on their behalf. Instead, his new book, Investing Demystified, advocates investing cheaply and effectively through the simplest products available.
