How can we re-engineer our media consumption to make it more useful to our needs? Economic Innumeracy : Some individuals experience math anxiety, but it only takes a bit of insight to navigate the many ways numbers can mislead us. We evolved in an arithmetic world, so we are unprepared for the exponential math of finance.
Sherman oversees and administers DoubleLine’s investment management subcommittee; serves as lead portfolio manager for multisector and derivative-based strategies; and is a member of the firm’s executive management and fixed-income asset allocation committees. He is host of the podcast The Sherman Show and a CFA charter holder.
And my dad had always said, as many young kids get this advice, doctor, lawyer, accountant, engineer. 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.
What Shift EV does is it takes existing delivery vans and retrofits them in a space of a couple of hours, from internal combustion engine to electric. What do they do with the internal combustion engine and — WENGER: That’s a great question. RITHOLTZ: A couple of hours? WENGER: A couple of hours. RITHOLTZ: That’s amazing.
MARTIN: So I remember when I came home from elementary school one day, and my dad who was an electrical engineer, he used to design fuel gauges on airplanes, came home with this huge box. We’ve recently upgraded our systems to our next generation matching engine technology. And it was a Commodore 64. I said, “What’s that?”
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?
You would offer three of their stock picks where they were probably touting stocks they wanted to unload from their portfolio. But the numbers you can’t argue with, I mean, we all know that the brutal math of investing before costs investors collectively will earn the market return after costs. That’s exactly right.
I — I loved math, but really, I was going to go down that literature route more than anything else and — and study Spanish literature. And so, getting to your question about equities where we’re positioned right now, equities absolutely can conserve an important part in the portfolio. I was econ and kind of geeky.
Her job is portfolio and product solutions and that means she could go anywhere in the world and do anything. One, one is true and I’ve always said is that I wanted people to stop, ask if I could doing math. And no one asked me if I can do math anymore with a degree from Booth, particularly in econometrics and statistics.
00:03:14 [Mike Greene] So that was actually an outgrowth from my experience coming out of Wharton and you mentioned the, the, you know, the transition of people who tended to be skilled at math or physics into finance. Initially I joined to help them manage their equity portfolio. It was the exact same trade.
If you’re at all interested in focused portfolios, the concept of quality as a sub-sector under value and just how you build a portfolio and a track record, that’s tough to beat. That led me down that track and really well, I had a software engineering job. I found this conversation to be really fascinating.
DAVIS: It’s a long story, but originally I went to school for engineering. Got to school, realized that I wasn’t very good at mechanical drawing, which is a big part of aerospace engineering curriculum. Undergraduate, you get a BS in insurance from Penn State. What led to an interest in insurance?
ANAT ADMATI, PROFESSOR OF FIANCE AND ECONOMICS, STANFORD GRADUATE SCHOOL OF BUSINESS: So, my journey starts where I took a lot of math. I was good in math and I love the math. So, I was kind of, in my romantic mind when I was in my early 20s, I was going to take but not give back to math, that kind of thing. ADMATI: Yes.
00:02:13 [Speaker Changed] Well, actually I started out electrical engineering. First, 00:02:18 [Speaker Changed] First two years, electrical engineering. I’m good at math and science and you know, I always had an idea what go into business, but I felt that electrical engineering would be a good foundation.
All of their portfolio managers 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. So we really think that it creates alignment to have our portfolio managers meaningfully owning shares of the funds that they manage.
He really began as a traditional engineer/finance person working at IBM as a network engineer before he got his MBA at Duke. I look for people that have done extracurricular work, or you know, manage their own little portfolio, or have stock ideas or businesses ideas that they want to pitch. His name is Marcus Shaw.
STEM (science, technology, engineering and math) funding is steadily declining—a dynamic that potentially opens the door for China to gain ground on the AI innovation front. China’s proactive steps are particularly notable at a time when U.S. Sharpened by both the U.S.

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 portfolio management role for like a single client account type business. And then I worked on it throughout the GFC and then became the senior portfolio manager during the recovery period.
And when used for ROE, as per the basic rule of math, if the denominator decreases, the fraction as whole increases i.e, The product portfolio includes dominant brands such as Pampers, Gillette, Whisper, Old Spice, Head & Shoulder, Ariel, etc. It is because having excessive debt on the balance sheet can inflate the ROE. higher ROE.
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. BERRUGA: So many of our clients were struggling to find alternative sources of income for their portfolios.
But you know exactly how they’re going to interplay within a portfolio, hugely powerful. You know, it’s not the equity market, and I run some big equity portfolios, you know, different. But, you know, it’s been in a portfolio for a long time. Last year, it’s in our tactical portfolios.
BRYANT: So money, unlike math, money is highly emotional. And of course, we can see today that the moral capital in America, which is Atlanta, is also the largest economic engine in the South built on, like New York, diversity and inclusion and good common sense. RITHOLTZ: Right. BRYANT: Number two, money is emotional. RITHOLTZ: Yes.
Work as a grocery store cashier You could be a grocery store cashier if you're good with math and don't mind scanning coupons and small talk. Once you figure out which digital product you're comfortable designing, you can create a portfolio for potential clients. Consider saving up to purchase a car entirely in cash.
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. It’s just math stick to it over long periods of time. And then I was looking for something more applied. The second is excess returns.
So like a component of it was like the standard derivatives math, right? And so like, you know, I got there and I learned derivatives math, right? It was derivatives math, it was like working with the traders on like risk management. Like, like the, you know, like the accounting standards.
That’s a really easy portfolio to create. It allows you to understand, generally speaking, what is a reasonable beta for that whole portfolio.

If you are to divide your portfolio with equal allocations to each of the 10 companies, you have an average annual dividend yield of 4.3%.
While we are no great example of financial success, we do own a nice home, have a reasonably sized investment portfolio and receive a solid pension income. So I did the math on that too**. I am a retired, married Navy veteran living in beautiful (but expensive) San Diego. So the worst case scenario is still not all that bad.
So it’s, it’s just kind of ironic, and I’ll just throw this out as a bit of an advertisement, but like, we run a portfolio of 10 stocks, a concentrated portfolio, 00:27:41 [Speaker Changed] 10 stocks, 10 00:27:42 [Speaker Changed] Stocks, that’s it. So that’s the math. Annually, okay.
But it just, he just, so we hired him and then we hired more engineers and we hired product people and you know, we made the app functional. 00:40:26 [Speaker Changed] They, they know, they know math, they know math. Nobody cares about your portfolio. John Wasserman is my audio engineer. Anna Luke is my producer.
.” It’s really helpful to have had five other meetings with people who sit at analogous funds that had losses that were just as big, and in fact, they may have contributed to those losses more and be able to tell him, first off, your fund, just by my math, has a $250 million management fee. They get trained at great places.
So 00:09:10 [Speaker Changed] I know Orion for many years because from the RIA perspective, from a registered investment advisor perspective, clients want to know how their portfolios are doing, what their performance is, both in absolute terms and relative to benchmarks. So tell us a little bit about that.
They believed in building businesses and far less focused on financial engineering. The key is to build — think of private equity as a business that builds businesses, and make that business engine stronger and stronger. RITHOLTZ: So it’s different math then I need 100x winner versus 99? KLINSKY: Yeah.
She was a partner and a portfolio manager at Canyon Capital, a firm that runs currently about $25 billion. But it’s interesting that you really can pinpoint the difference in return because there’s this sort of impatient or overzealousness in trading your portfolio. Justin Milner is my audio engineer. I get that.
And I was a math nerd as a kid. So, so let’s talk a little bit about picking international stocks as an asset class has done fairly poorly, but it’s nearly a third of your portfolio and, and you continue to outperform. So, so you set to retire as portfolio manager this year, you mentioned your two successors.
By the time you got to ’87, right, the futures were five years old, people thought there was going to be portfolio insurance, that there was going to be this massive, always liquidity that you could stay longer stocks and that you could sell futures against it. And so it’s one of these things that math works.
The transcript from this week’s, MiB: Antti Ilmanen, Co-Head, Portfolio Solutions, AQR , is below.

I was an undergrad studying business and engineering. You’re accidentally waiting into yet another quant controversy, whether you need both these characteristics in every stock, or whether you can have some stocks that are great on one and simply average on the other and the portfolio comes out. Tell us a little bit about that.
Because he was all sure he was a totally isolated math. So, so he’s brilliant at math. He goes to m i t to study, study physics and math. So brilliant enough so that sure, he goes to math camp in the summer and find, kind of finds his tribe. But in math camp, he’s not the best. And the Undoing project.
So that’s an active part of portfolio trimming and opt and optimization. The good news is no one event has a big impact on the portfolio. And I was always good at math and, and I had been writing code since I was in the sixth grade. Kayleigh Lepar is my audio engineer. So I had real support around Wall Street.
Not only did he stand up a research shop from a dorm room in college and started selling model portfolios to fund managers, but eventually created a suite of first mutual funds. And I, and I really like the application of math and statistics and computer science to markets. People have described that in the past as portable alpha.
The academic side of how to build a portfolio, we can argue about the details, right? As an advisor, you could get somebody’s model portfolio, or you could hire some, you know, three CFAs and do it yourself. Some advisor that’s out there can say, “I have generally 1% alpha for the last three years in my model portfolio.”
