Jean-Philippe Bouchaud On How Financial Markets Behave Like complex Ecosystems

Jean-Philippe Bouchaud is Chairman of Capital Fund Management (CFM). He founded ‘Science and Finance’ in 1994, the research arm of CFM with Jean-Pierre Aguilar, which merged with CFM in 2000. He supervises the research team alongside Marc Potters. Jean-Philippe maintains strong links with the academic world and is a professor at École Normale Supérieure (ENS). Prior to CFM, Jean-Philippe was a researcher at the Centre National de la Recherche Scientifique until 1992. Following this he spent a year at the Cavendish Laboratory in Cambridge before joining the Service de Physique de l’État Condensé at the Commissariat à l’Energie Atomique in Saclay, France. He holds a PhD in theoretical physics from the ENS in Paris.Follow Jean-Philippe Bouchaud on LinkedIn Here are the questions we covered during this session and their respective timestamps:04:23 — Arnav“So professor, over the 30 years you’ve witnessed numerous regime changes. So the dot com bubble, the 08 crisis, Covid, and the 2022 inflation shock, for example, which regime change challenged CFM’s systematic approaches? And what did you learn about building strategies that can survive multiple regimes such as these?"12:19 — Nihar“So if you like, in next 20 years, what, which technology will be the regime change like AI and ML. Sorry, can you — so what would you say the next kind of technology or something that could change, like AI for example, would cause the next regime change? That’s also important for you as a fund.”15:27 — Vincent“So how then would you like prepare yourself in the sense that, okay, you don’t know what’s going to happen even tomorrow. But what are some things where if you’re if you have a trading firm or a fund or any financial institution, or you’re maybe running your own strategy, how would you say then to mitigate risk or try to prepare yourself for these sort of unknown things that are going to happen?”19:16 — Nihar“So my main question is, you mentioned in the Global Trading interview that the COVID vaccine announcement November 2020 hurt CFM badly because it created a strong divergence between stay home and go out industries that wasn’t expressing risk before the pandemic. How do you systematically detect emerging risk factors that aren’t in their historical data? Is this even possible or did we just have to accept getting hit occasionally?”26:38 — Arnav“So what do you think the trade off between publishing openly and maintaining proprietary advantage and what role should systematic hedge funds play in advancing academic finance?”45:26 — Vincent“Where would you say are things that align most with physics and mathematics and then the financial world?"51:03 — Vincent“Do you then also think that we’re entering sort of like almost like a dangerous space where fewer and fewer people actually when it comes down to it really understand like the complexity and like what it actually means or what the system is actually doing? Do you think that’s also dangerous in that sense for maybe the entire financial system?”58:30 — Vincent“So just very quickly maybe in like one, two points, what do you think the industry will look like in 10, 20 years?”Mentioned during this episode:- CFM Official Website - Bouchaud, J-P.
