Today I am a full-time private investor, trading whatever I find interesting. I am running my own tiny family office and foundation. JMR Investing currently consists of myself, my brother operating as a fractional CTO, and a few consultants from Brazil. My latest writings can be found on my Substack, and they help me focus my thinking and make new connections with investors. It is mostly cyclical macro. On the single-name equities side, I am trying to replicate some of the benefits of scale by finding pockets that are interesting from a value/capital cycle/event-driven perspective and then relying on subscriptions to replicate being a synthetic portfolio manager. It is nice being able to fish in small pools, and collaborate freely with other investors.

Prior to that, I worked at Bridgewater Associates from 1998 to 2023, where I was the co-head of the Macro Team, responsible for maintaining our views on cyclical conditions for all major economies. For 25 years, I wrote at least one weekly research piece for institutional investors and policymakers. A lot of samples are included here, though keep in mind that these relied on great analysts, peers, data, feedback, and a fertile intellectual environment I am no longer a part of. Even with that, I did get a lot wrong, as these pieces also show. My main market focus was trading short rates (views on monetary policy), though I also worked in the later years on some individual equity strategies. I grew up in Brazil during the hyperinflation years (where I developed my passion for macro) and went to a generic Ivy League school, where I developed a passion for bridge and fantasy baseball.

I live an hour from NYC with my wife/high school sweetheart and a greyhound. My main other interest is helping other humans irrespective of who they are or where they live in the most cost-effective way possible (i.e., the classic flavor of effective altruism as practiced by Givewell). While I have zero political aspirations, I am also spending a lot more time thinking about the U.S. political backdrop because I really like living here. My grandparents were Holocaust survivors, and I don’t take anything for granted. I have recently supported the Voter Participation Center (a non-profit focused on getting young people, minorities, and unmarried women to vote), and I also love what the Forward Party is trying, but struggling to build.
