Welcome to Episode 250 of the Alpha Exchange. To celebrate the milestone, I asked my dear friend, Jon Kalikow, to host the conversation, switching seats and having me as the guest. I launched the podcast in 2018 with a simple idea: to create space for long-form conversations that explore how market practitioners think about risk. Rather than focusing on predictions, the goal has always been to und...

The “risk-free” rate figures prominently in how we’ve all been taught the foundations of finance. To price a security, start with the asset that is the safest and soundest and then add compensation for bearing uncertainty. It has always been self-evident that the global risk-free benchmark was the Treasury market. Deep, liquid and viewed as default free, US government bonds have been the recipient...

Five years ago, on January 27th, 2021, the frenzied buying and speculation in Gamestop hit its apex.
