Today on the podcast, Michael Covel opens up with a monologue and closes with an interview of him covering trend following ‘fundamentals’. Covel opens up by discussing how the phrase “black box” is used to marginalize those who practice trend following trading. Next, Covel plays an interview clip from James Simons, the chairman of Renaissance Technologies, who generated for himself over 14B USD all through models. The second part of today’s episode are highlights of Andrew Horowitz’s interview with Covel–an interview *of* Covel this time. Covel and Horowitz discuss the TurtleTrader story; black boxes, emotions, and computers; what trend following is from the most basic level; the question of “why”, and why it might not be as important as many people think; finding which markets to enter; finding the optimal bet size; and how Fed intervention plays into the market.
