What's the optimum amount of money you should bet on a particular outcome? The answer is dictated by mathematics, yet plenty of people still go against the laws of numbers and probabilities when it comes to investing. This week, we speak with Victor Haghani, CEO of Elm Partners Management and the co-founder of the collapsed hedge fund Long-Term Capital Management, about the most important mathematical concepts for investing. We also discuss the pros and cons of quantitatively led finance.

It is hard to have a markets conversation that isn't out of date within a minute or two. But we think this one, with Ozan Tarman and Aditya Singhal of Deutsche Bank, is basically evergreen. This conversation, recorded at our live show at Wilton's Music Hall in London, is all about fundamentals: How Tarman, DB's vice chair of global macro, and Singhal, the firm’s head of EM trading across rates, FX and Credit, make sense of conflicting headlines, whether the rally in tech stocks is to be believed, the tug of war between fast money and central bankers, and how traders are evaluating the difference between the AI models coming out of the US and China.

Deutsche Bank's Ozan Tarman and Aditya Singhal on Understanding the Macro Risks

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/747e9d28-f7df-4926-bc64-b44e0124705e/transcript

Whether it's the price of a barrel of Brent crude or a pound of beef, it's clear prices are skyrocketing for all kinds of goods and commodities. Price shocks and shortages are, if anything, the way consumers understand the economy right now — at the grocery store or at the gas pump. Certainly, current (and future) shocks can be explained by the closure of the Strait of Hormuz. But the environment is weirder than just across the board price increases: The price of corn has barely moved, for instance, while fertilizer just keeps going up. We have not one but two perfect guests to talk to us today, our favorite commodity specialists: Bloomberg Opinion columnist Javier Blas and Lorcan Roche Kelly, the business editor at Irish Farmers Journal. Today's episode — which was recorded on stage at Wilton's Music Hall in London as part of our first ever show outside the US — covers how the world's farmers feel about US trade policy, why today's energy shock is so different from 2022's, the true impact of the UAE leaving OPEC, and why it's going to get harder to buy hard cheese in the near future.

Why the Price of Oil, Beef, Electricity, and Everything Else Makes No Sense

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/2cddec97-5995-4812-abea-b44b016dc69f/transcript

The internet is made for shopping. For years, the main inputs for e-commerce transactions involved targeted ads, algorithmic recommendations, SEO, and lots of mindless scrolling. But agentic commerce might represent a sea change for e-commerce: With the rise of AI agents doing shopping on behalf of consumers, how are retailers going to adapt? John Collison, co-founder of the financial services and payment processing company Stripe, has first-hand experience with all the ways e-commerce has changed in the last decade, and he thinks agentic commerce is going to completely transform the online shopping experience. On this episode, we speak to Collison about how AI has already changed the way consumers make purchasing decisions, why keyword search is a "ridiculous" way to find things to buy, what it means when brands will have to appeal to AI agents as opposed to human buyers, and if AI agents can truly mimic human taste.
