In today’s episode, we are exploring the evolution of quant investing with Dr. Jonathan Briggs. Jonathan holds a Ph.D. in mechanical engineering and applied mechanics from UPenn and has had a long career of researching and developing investing techniques for pension funds, such as the CPP Investment Board. He is now the CIO of his own fund, Delphia, where they are implementing techniques developed from his research.

Trey Lockerbie (00:25):
In this episode, we discuss the basics of quant investing, the commoditization of the approach and what has led to a quote-unquote quant winter, how size and scale apply to the strategies, how machine learning is playing a bigger role in the quant approach, the economic framework Jonathan has devised after decades of research and much, much more.

Trey Lockerbie (00:43):
This was a very interesting look into the Moneyball approach of investing. Does it invalidate fundamentals? Let’s find out in this discussion with the very thoughtful Dr. Jonathan Briggs.

Intro (00:53):

Trey Lockerbie (01:17):
Welcome to The Investor’s Podcast. I’m your host, Trey Lockerbie. And today I am so excited to have on the show, Dr. Jonathan Briggs. Welcome to the show.

Jonathan Briggs (01:25):
Thank you very much. Doctor, not a real doctor, though.

Trey Lockerbie (01:28):
If you’ve got a Ph.D., you’re a doctor to me.

Jonathan Briggs (01:32):
Fair enough.

Trey Lockerbie (01:33):
Speaking of which, you’ve had an incredible career. And maybe talk to us about that Ph.D., and then how you found your way into finance and how you’ve started to develop the approach you have today. So let’s start all the way back and go from there.

Jonathan Briggs (01:46):
Go to the origin story, huh? So that’s, the Ph.D. is I was interested in applied math engineering. So that was my first love, which was obviously why you go into a graduate program, to begin with. And in particular, I was focusing on something called control theory, which is a set of theories about how you manage to make systems do what you want them to do. So how do you make an aircraft behave the way you want it to? How do you make SpaceX land vertically on a small ship? So that’s all control theory. Or Tesla, how it self-drives.

Jonathan Briggs (02:13):
That was my passion. There were certainly, obviously, life never goes in one particular direction and you never end up in the spot you thought you would. And that was true with me. And so for personal reasons, we had to move close to my wife’s family after I graduated. And that turned out to be San Francisco, California.

Jonathan Briggs (02:31):
And while I was there, I just basically had to look for a job. So any plans of going on into academia, put by the wayside and I had to find someplace to use my talents and get paid, effectively. So when I showed up in San Francisco, there were only certain numbers of places that we’re hiring. Remember, it was pretty close to the .com bubble. So tech really wasn’t the place to go. And it turned out that finance was higher up. In particular, Charles Schwab was looking to hire folks with a background similar to mine to help them build, which essentially turned out to be a robo-advisor.
