Bond Trading

I’m excited to share my conversation with Mary Childs, author of The Bond King (and co-host at Planet Money) on the rise and fall of legendary bond manager Bill Gross.

Mary and I talked about Bill’s breakfast habits (did low blood sugars end his career?!), his card counting days, the culture of paranoia at PIMCO, how he combined multiple sources of edge into “structural alpha” for long-term outperformance, the difficulty for a founder to leave their firm, Bill’s desire for fame, and how emotions ultimately got in the way of investing.

Some highlights from the conversation:

Opening the door to a story: “If you're staring at a closed door … you just have to come up with a little piece of information to get that person to open that door, to crack it open. A little piece of gossip, a story that everyone's talking about. In and of itself that gossip is useless to you as a journalist, of course. But you can asking somebody, Hey, I keep hearing this ridiculous story. You have a little nugget of truth in there. You don't know what it is yet. … A lot of people want to help you understand and don't want to see the story misrepresented.”

Traits of a founder: “The things that make someone capable of achieving the track record that Bill Gross did, building the kind of firm that Bill Gross was a part of, those personality traits are: you're going to be exacting. You're going to be really intense and focused. You're going to be a perfectionist, a micromanager. You're going to keep a really tight grip. These things, generally speaking help contribute to the success of the firm. … For the most part, these are things you see very frequently among founders, and also that toxic culture that can often come along with some of those traits. Those traits also make it very difficult, if not impossible, to have a graceful transition away from that founder. Because the minute they start to loosen their grip, they freak out. … The tight grip is who they are. This firm is who they are.” 

Being the house: “Bill gross learned from Ed Thorp’s book called Beat the Dealer that you can count cards. … I think that this sensibility of both understanding the math but also feeling the pace of the table and knowing when you have that edge and when you don't, and also watching all the people around you who have no edge whatsoever and who were just flopping around taking dumb chances. All of that helped to inform how he approached the market and who he saw as his competitors. His competitors, aren't the dumb people doing the dumb stuff. His competitor is the market, is the dealer.

This shows up when PIMCO figured out that the US government wasn't going to let certain institutions fail in the financial crisis. That there was going to be a government backstop … If I know that the US government is the house, I'm going to be the house, I'm going to try to align my own interests. … The point was to do what the government's going to do, but do it first: buy what they're going to buy and then sell it to them or ride that wave as the news of their purchase causes the price of those assets to soar. And that's exactly what happened.”
