Jim O'Shaughnessy wrote the wildly popular investing book, "What Works on Wall Street," in which he documents the strategies that sank or soared during over long periods, with some surprising results. In the podcast, Jim expounds on the follies of predicting markets and how a composite approach outperforms. It's only possible, he says, if you can eliminate those pesky emotions. Jim will also give a presentation at the 2018 GuruFocus Value Investing Conference.
