Today on the Rational Reminder Podcast we interview a seasoned journalist from The Wall Street Journal, Greg Zuckerman. With 23 years of experience with the media outlet, Greg has written extensively about the most prominent figures in the world of investing, including Jim Simons, John Paulson and Carl Icahn, generally focusing his attention on significant trades, traders and fund managers. In this episode, Greg shares how covering the stories of renowned investors and fund managers have influenced his investment philosophy. Specifically, we get into his book about John Paulson, The Greatest Trade Ever, and why Greg reckons Paulson never managed to achieve the same level of success following this famous trade. His work on the founder of Renaissance Technologies, Jim Simons, also produces fascinating points of discussion, including why their Medallion Fund became so successful and how capping the size of the fund contributed to its outstanding performance. Greg also talks about the idiosyncratic character of Simons, the role of luck, why taking an algorithmic approach to investing is likely to produce good outcomes in the long run, and why people should not always pay attention to the advice of "smart money" sources like hedge funds.
