She has a really fascinating background, very eclectic, a combination of math and law. You, you get a, a BS in Mathematics and a JD from Boston University Math and Law. It is something, math has always come easy to me since a child. I didn’t get an advanced degree in math. Not the usual combination. What happened?
This year, its performance has it the top 1% of mutual funds but in “2021 and 2022 it was ranked in the bottom 100th percentile.” Here I am talking not just portfoliomanagement but overall lifestyle, habits and choices and yes this does filter into my day job managing investment portfolios.
I’d say management consulting is any of the other thing that least at that time was the other career trajectory, just my personality, more of a math oriented introvert. Now I do fundamental side research portfoliomanagement, which I just, 00:08:20 [Speaker Changed] So, so you joined GMO, there’s 60 people, 30 years.
All of their portfoliomanagers not only are substantial investors in each of their funds, but they do a disclosure year that shows each manager by name and how much money they have invested in their own fund. What, what were you guys doing in 2022 when the s and p was down about 20% and the NASDAQ was down about 30%?
So I took it upon myself to go off and took a course in bond math, took another course in derivatives and realized the underlying fundamental concepts were barely, I mean, it wasn’t even high school math in most cases. RITHOLTZ: So you mentioned earlier 2022 was so unusual. So we start with a strategic asset allocation.
I was always good at math, but I really, I just didn’t relate to things that were more esoteric bonds options. I worked in sort of a quasi portfoliomanagement role for like a single client account type business. And I, I think that I kind of triangulated on it. I have no family history. I had two stops before then.
And I did the math, and I think at that point in time, roughly speaking, assets in ETS were roughly just 10 percent, 12 percent of assets in mutual funds and I was pretty convinced that that number was to increase significantly. How do you manage through volatility like we’ve seen in 2022? BERRUGA: Yeah. BERRUGA: Yeah.
But yes, I was given my own column and by that point, having seen all these star managers come and go, you know, I had become an index fund devotee, and in column after column I banged the drum for index funds to the point where my editors were asking me, Hey, could you write about something else? It’s, it’s a temporary move.
But it was a tremendous experience because I had started off in bond trading, worked my way into portfoliomanagement and running the bond indexing team for a number of years, and then I got asked to take this responsibility, which was much broader. Go to the decade before 2022, the equity side was something like 13%.
Even with 75% accuracy we only move from an investable universe where 30% of constituents outperform to now selecting the portfolio from a pool with a 56% win rate. We all know that a 55% hit rate is the top decile across the industry, and the maths above demonstrates why. This is why industry hit rates are so low.
So I, I did a math degree at Oxford, which is more pure math. You know, pure math can be very theoretical and detached from the real world, and it’s getting worse. Those have compounded over the centuries and have managed to amass a huge amount of, of capital. He is portfoliomanager at Orbis Holdings.
So, first, I found the book to be quite fascinating, very in depth and you managed to take some of the more technical arcana and make it very understandable. You began as a central bank portfoliomanager in Finland. So, that relationship actually already started when I was a portfoliomanager, right? ILMANEN: Yes.

I was a fixed income portfoliomanager and trader, which is a ton of fun. PIMCO out on the West Coast, read the first thing I wrote in the Journal of PortfolioManagement. My mom was a math teacher so — RITHOLTZ: Okay. But it wasn’t like whatever skills they taught me in the PhD. RITHOLTZ: Meaning what?
I’m kind of in intrigued by the idea of philosophy and math. So I found myself getting kind of bored with my math problem sets, and then I could shift to philosophy and then go back and forth. And somehow in 2022 when, when stocks were down about 20% and bonds were down about 15%. What was the career plan?
Jeffrey Sherman : Well, what it was was, so I, as I said, with applications, there’s many applications of math, and the usually obvious one is physics. Barry Ritholtz : It seems that some people are math people and some people are not. The, the math came easier. And I really hated physics, really. It’s so true.
I’d been ranked i i back in the seventies, if you can do the math. He helps portfoliomanagers make sense of the world. And I get the sense that the transitory nature and, and granted transitory took a little longer than people expected, but again, that long and variable lag inflation peaked in June of 2022.
