What Seth Klarman said

Written from the verified transcript and checked against it. Every figure links to the moment it was said.

Seth Klarman discussed his path to investing, starting with childhood entrepreneurial ventures and buying Johnson & Johnson stock at age 10. He co-founded Baupost in 1982 with $27 million from four families, later gaining control through a handshake deal. Klarman emphasized bottom-up investing, learning from Ben Graham and Warren Buffett, and the importance of downside protection. He wrote 'Margin of Safety' in 1991, which gained a cult following. During the 2008-09 crisis, Baupost raised significant capital and deployed it into distressed assets like GM, Chrysler, and Ford auto finance debt. He acknowledged holding too much cash in recent years and shifted to more liquid holdings. Klarman sees AI as a sea change, with opportunities in data centers and assisted living, but worries about market speculation and the SpaceX IPO. He values philanthropy and advises young investors to be contrarian and seek mentors.

Key takeaways

  1. Klarman said Baupost raised significant capital within a quarter during the 2008-09 crisis and deployed it into distressed assets like auto finance debt.
  2. He admitted holding 30% or more cash was a mistake in the post-2008 environment, leading to a shift toward more liquid holdings.
  3. Klarman called AI a 'sea change' and said Baupost owns private data center investments at a discount.
  4. He expressed concern about the SpaceX IPO, citing Goldman's estimate of 100x growth needed to justify the price.
  5. Klarman said he wished he had understood the importance of venture capital and Silicon Valley's economic engine earlier.

Barry Ritholtz 0:16 ↗
What can I tell you about this week's banger? Seth Klarman, legendary value investor out of Boston at the Baupost Group. What a fascinating discussion about risk, about the current environment, about the Boston Red Sox, about just about anything that affects portfolios, distressed assets, stocks, bonds, real estate. I thought this was fascinating and I know you will also. With no further ado, my conversation with Seth Klarman.
Seth Klarman, welcome to Bloomberg.
Seth Klarman 1:02 ↗
It's so great to be here. Thank you, Barry.
Barry Ritholtz 1:04 ↗
Thank you so much. I've been looking forward to this for forever. Before we get into your investment philosophy and the development of Baupost, I have to roll back a little bit to your early days. Economics from Cornell, an MBA from Harvard. What was the original career plan?
Seth Klarman 1:27 ↗
I was always drawn to investing. Even when I was a very young kid, I was interested in baseball statistics. I became aware that there were these other columns of numbers in the newspaper and asked my neighbor what those were and started to understand and follow the stock market a little bit. I didn't really ever develop a career plan, but I was drawn to the stock market. I think I'm drawn to puzzles. I like doing word puzzles every day. I like solving math puzzles. I subscribe still to a math puzzle book published by Dell. The stock market's a big puzzle. The financial markets are a big puzzle. How does it all work? How does the performance of companies get reflected in stock prices and how can an investor outperform everybody else? All of that is what drew me in.
Barry Ritholtz 2:27 ↗
So I'm interested in how you first found that beyond the newspaper stock price pages. You grow up in Baltimore. Your parents divorced when you were relatively young. Mom was an English teacher, later a psychiatric social worker. Dad was a health economist at Johns Hopkins and NYU. Was it just simply thumbing through the sports pages literally to the next set of pages where the stock pages?
Seth Klarman 2:56 ↗
That's literally the numbers on the page attracted my attention. I think my origin story is a lot like other people who ended up in the investing business, like Warren Buffett, like I think Todd Combs, like many others. Drawn to small businesses, wanted to make money. I was delivering a newspaper route for the Baltimore Sunpapers. I had a snow cone stand in my driveway one summer. I mowed lawns. I raked leaves. I shoveled snow. I did little carnivals for the neighborhood kids. I sold candy at religious school on Tuesdays and Thursdays because the kids were starving after school and I would buy it over the weekend and bring it to school and sell it for an arbitrage profit. It was just a pattern of being drawn to small business and making money. Over time that led to an interest in the stock market. I bought my first stock with some bar mitzvah money when I was around 10 years old.
Barry Ritholtz 4:00 ↗
Well, it couldn't have been bar mitzvah money if you—
Seth Klarman 4:02 ↗
It wasn't bar mitzvah money then. It was a present, but then bar mitzvah money continued to be piled in.
Barry Ritholtz 4:07 ↗
10 years old and—
Seth Klarman 4:09 ↗
I bought a share of Johnson and Johnson.
Barry Ritholtz 4:11 ↗
Still have it?
Seth Klarman 4:12 ↗
Do not still have it. It split three for one, but ultimately I presumably have traded that in for something else that I like better.
Barry Ritholtz 4:18 ↗
So let's fast forward a little bit to the Baupost origin story, which isn't that far ahead. You're only 25. The urban legend is you co-founded Baupost, but reality, you were brought in to manage money for the four founding families. Still at 25, that's a kind of shocking thing. Oh, we have all this wealth, let's bring in this kid to run our portfolio, right?
Seth Klarman 4:48 ↗
I would say the same thing if I were in their seats, I would wonder, how does this kid know how to do that? I don't think people should generally be starting investment firms at age 25. And of course, I really didn't start the firm. The firm was in the process of being created. The four clients of the firm that came together, the founders had the idea that they would build a firm that might make investments itself, might hand money to others who were in the business already of making investments. I think they wanted to build an institutional structure or framework for how to make sure the money got managed well given what was then back in the early '80s a highly fraught time. Volatile markets, long history of underperformance of the stock market, real economic uncertainty, stagflation. Treasury bond yields were getting higher and higher. It was a really fraught moment. They wanted to make sure the money they had not only was kept intact, but was accounted for, clip the coupons and collect the dividends. The founders were all selling businesses around that time. The serendipity was I was a student at business school. Bill Poorvu, the CEO of Baupost, was my real estate professor and he and some friends were selling Channel 5. A third friend had a computer publishing and consulting business. All that was getting sold. So they had this pile of $27 million. And the basic job offer I got wasn't come run a fund, it was come join us and let's figure out smart things to do with the money.
Barry Ritholtz 6:43 ↗
So eventually you become the lead partner there. I don't know if CEO is the right term.
Seth Klarman 6:49 ↗
I wasn't CEO for the first seven or so years and then I became CEO and effectively got control of the firm as sort of a handshake deal where we agreed that if I worked hard and did well for the clients that they would recognize that with a stake in the business. So I had no stake the day it was formed and ended up with over half.
Barry Ritholtz 7:12 ↗
Ended up with over half. That's amazing. 40 something years later—
Seth Klarman 7:16 ↗
And now much less because I'm a big believer in sharing the pie with my team.
Barry Ritholtz 7:21 ↗
Makes a lot of sense. Let's talk a little bit about the timing. You mentioned there was a lot of turmoil and stagflation. The previous 16 years, inflation-adjusted returns were something like down 75% from '66 to '82. '82 was the beginning of a historic bull market. How did that affect how you thought about risk? How you thought about opportunities? What did the markets look and feel like in '82 when I imagine most people were still pretty bearish?
Seth Klarman 7:59 ↗
Right, I think Malcolm Gladwell would look and say 1982, what an interesting time to start an investment firm. That certainly was a wind at your back in terms of being successful. The challenge is, you had no idea that you were at the beginning of a long bull market. What you felt was the market hasn't done that well for a long period of time and people were very skeptical about it. And you can always point to things at any moment that don't add up, that seem overvalued, that seem risky. And yet we get through most of those things. So at the time it didn't feel like a gimme, it didn't feel like a layup hand. But what ended up happening was we tried to make money apart from the market. We weren't buying an index. We were buying idiosyncratic situations, looking for bottom-up mispricings and that led to us building a record. So while it looks just okay compared to the market over that period of time, I think we would have done okay whether the market had been up, down, or sideways.
Barry Ritholtz 9:10 ↗
Really, really interesting. Given you're coming off of what was an epic bear market and just a whole lot of cross-currents, stagflation, super high rates under Volcker, you're not that far away in '82 from the end of Vietnam, Watergate, all that malaise. How did that environment affect you as a professional investor? How did that change how you looked at the world and what lessons did you take from it?
Seth Klarman 9:41 ↗
I would tell you I think every investor needs to be a student of history. It may not repeat exactly but it certainly rhymes, and it is very valuable to understand, especially financial history for an investor. What are the worst moments? How did we go through a market crash in 1929 to 1933 and a great depression that lasted close to a decade? What must that have been like for the people at the time? Even the greatest acclaimed value investor of all time, Benjamin Graham, nearly went broke twice during that era. I think it's incumbent on all investors to be thinking, maybe holding multiple inconsistent thoughts in their head at the same time: I found this interesting opportunity today, this bargain-priced stock for whatever reason it's out of favor. But you've got a backdrop of, from time to time as we do today, a very expensive market and a bit of euphoric conditions. Is that dangerous? It's dangerous, but we're also at the cusp of maybe a groundbreaking new technology. Over the 40 years it's always been some of both. What I deeply believe is that value investors make money staying bottom-up. You might have a top-down view, you might say this could be a bubble. But bottom-up is where you're going to devote your time. It keeps you anchored. If you have a portfolio of bargains, you're probably going to do okay if you've stress-tested them and if you've been intellectually honest about them and they really are bargains.
Barry Ritholtz 11:43 ↗
So you mentioned Ben Graham. I'm curious as to who else were important influences on the development of your investment philosophy. I've read about Michael Price and Max Heine who affected you the most over the years. Who still affects you?
Seth Klarman 12:01 ↗
Reading Ben Graham was certainly a major influence on me as he has been on essentially everybody in the value investing community. And then Warren Buffett, the real-life practitioner of Graham. It was always heartening to know that somebody like Buffett who seemed to think similarly to how I thought, thought about downside risk, thought about the need to stay focused in individual companies and not worry so much about the overall market, the willingness to hold cash, and concurrently the willingness to not have an opinion on everything. I have a lot of ideas and I end up with no opinion, no position. But once in a while we find something that seems way off the beaten path that's really interesting. To watch Warren Buffett do that, I've realized now that Warren probably had a certainty of the idea that he would compound capital over a long period of time. And I think that's something that Graham probably gave Warren, gave me as well. The idea that if you protect on the downside, if you don't find yourself getting margin calls or frozen in place or getting massive redemptions because you're down so much — if you can position yourself that way, it can leave you in a position to play offense when even your best competitors might not be on the playing field. That's a huge advantage. Graham is kind of a north star. It's a place where you can stay focused on what something's worth. You can ignore the herd. You can ignore the siren song of growth at any price and exciting new technologies and exciting IPOs. You can ignore all that because you have a confidence that I own something that's going to be worth more a year or two from now than it is today. That's the underpinning that lets you follow a value investment strategy.
Barry Ritholtz 14:07 ↗
So you mentioned downside risk and that we referred to before you began in 1982. Less than a decade later you publish Margin of Safety in 1991. What led to you at the ripe old age of 34 to write a book on risk management? What was the motivation? How was it initially received? Because it's become so sought-after these days. What was the initial reception like?
Seth Klarman 14:38 ↗
In retrospect that looks pretty darn presumptuous. I got asked to write it by a classmate from business school who worked at Harper Collins. She had seen some of my client letters and said I seem like I'd be a good writer and maybe I'd have something to tell the audience. What I really thought was I'm just updating The Intelligent Investor for modern examples and a contemporary market. I thought maybe I'd make it a little more accessible for the average Joe. I didn't think I would make money from writing the book. But you get smarter from the act of writing about what you do. You can do what you do all day long without maybe fully forming the philosophy, but if you want to share it with anybody else, it makes you think more clearly about what you do.
Barry Ritholtz 15:55 ↗
The former librarian of Congress, Daniel Boorstin, used to say, 'I write to figure out what I think.' And there's a lot of truth to that. What was the initial reception like? Did people respond or did it kind of land in a handful of value geeks bought it, but no one else?
Seth Klarman 16:13 ↗
So it's somewhere in between. What happened first was I think my editor got fired three different times, so I kept getting new editors. They had promised to back the book with advertising and they didn't. The book landed with a bit of a thud. I think they printed maybe 7,000 copies. I ended up buying a bunch of them back from Harper Collins by the time they took it off the market and the rights somehow reverted back to me. What it did do though, it was bought significantly by competitors who used it to train their teams. The starting goal was, the first half of the book was about the street and how they treat the average investor and the challenge of whether the investor is getting a good deal. The second half is an investment approach, a value-oriented approach and how an investor might think about doing that even if they're not a professional investor. It was successful in a weird way, because it didn't get republished, it developed a bit of a cult following, and that's kind of amusing and interesting to me. We've reprinted some on our own and made it available to our clients and to summer interns.
Barry Ritholtz 17:47 ↗
In 2023, the seventh edition of Security Analysis, Ben Graham's framework for investing, was edited by you and in a lot of ways substantially rejiggered. How different is this version than Ben Graham's? How did you approach this?
Seth Klarman 18:11 ↗
The earlier edition, the sixth edition, I was co-editor with Jim Grant and Bruce Greenwald. The seventh edition they asked me to just edit. We didn't follow the process that you might follow because we kind of thought of Security Analysis as the Bible and we thought we should leave it alone. What we should do is have modern-day expert investors write commentary about the different chapters and sections of the book. So that's what we did. The sixth edition and the seventh both have some really great selections by investors. My former colleague David Abrams' contribution in the sixth edition is one of the most brilliant things I've ever read. We're moving Graham into a different era. The thing that's beautiful about Graham is it was written a hundred years ago give or take, during the depression, and things that made sense in a depression haven't made sense every day since then. It was an update taking what's valuable, why people revere the book as a Bible, but also making it more accessible and more relevant for the modern day. We expanded it to cover some topics that weren't covered. It certainly has more international investing. It talks about some other private investments, changes in financial markets, the latest manias and fads, changes in market structure, changes in asset classes that have come into existence. All of that is a valuable updating of the literature and helps keep something relevant that deserves to be relevant.
Barry Ritholtz 20:17 ↗
Coming up, we continue our conversation with Seth Klarman, CEO and portfolio manager at the Baupost Group, discussing the firm's evolution and philosophy. I'm Barry Ritholtz. You're listening to Masters in Business on Bloomberg Radio.
I'm Barry Ritholtz. You're listening to Masters in Business on Bloomberg Radio. Our extra special guest this week is Seth Klarman. He's CEO and portfolio manager at the Baupost Group, a legendary value and distressed investment shop out of Boston running over $22 billion in assets. So let's talk a little bit about the way you think of opportunities and risks. During the 2008-09 financial crisis, you raised about $4 billion and the research I read, you were deploying $100 million a day into distressed assets. That seems like a big chunk of money. First of all, are those numbers remotely accurate? Is that ballpark?
Seth Klarman 21:32 ↗
It's ballpark. What I would tell you first of all is we had been closed for new clients much of our history, but we kept a list in case. When the market started to fall apart after Bear Stearns and then after Lehman, there were all kinds of things going on and people were in great stress as we entered the uncertainty of an economic decline that could have pretty epic proportions. It certainly was the worst decline since the Great Depression and it stands out as the mother of all bear markets for anybody in the last 100 years. The challenge was maybe it's time to take some capital and the odds are increasing every day that we're going to be able to deploy it fruitfully. Bear Stearns was spring of 2007, Lehman was September of '08. That's not a lot of time from there until March '09 when everything really bottomed.
Barry Ritholtz 22:44 ↗
How quickly were you able to raise capital, get the docs signed, and be prepared to deploy that as opportunities arose? Doesn't seem like there's a lot of time.
Seth Klarman 22:56 ↗
The team worked heroically and we were able to raise very significant capital within a quarter.
Barry Ritholtz 23:05 ↗
Wow. That's really quickly. Now you mentioned the team. I have heard some really interesting rumors and legends. How did you put this team together? What were their marching orders? How did everybody operate in that period of absolute turmoil and mayhem?
Seth Klarman 23:22 ↗
We already were an established firm. We'd been up and running for a couple of decades by then. So I had a team in place and they were deeply knowledgeable, experienced. Not everybody on the team has distressed asset expertise, but a very high percentage does. People at Baupost like being versatile athletes. We're nimble, we're agile, and we cross-train. Just like baseball teams are doing now in the minor leagues — they don't want you to just be a third baseman, they also want you to play outfield. The same with us, we have people in four different groups, but all of them can work on distressed situations. People in the private investments group especially love when we're super busy in the public markets and we call them in to work on distressed credit.
Barry Ritholtz 24:18 ↗
So big chunk of capital, very aggressively deployed in a moment in time when so many people seem to be just paralyzed and frozen with fear. Was it just the value analytical framework or was it a little broader and deeper than that?
Seth Klarman 24:36 ↗
The way you're conveying it probably comes across as we come in with giant satchels of money and hand over fist deploy it. It wasn't like that at all. It was the same cerebral, methodical, painstaking environment that we do every day. We see things trading at lower prices and we notice that and we look at the fundamentals. Everything we do at Baupost is bottom-up. Nothing's top-down. We're not saying probably a good time to be a contrarian. We're saying, oh, I can buy this bond at 70 that I think is covered at par. I think people are worried maybe it could have a blip or have a problem for a while, but people aren't really doubting that there's something there. As the economy got worse, people may have started to doubt more and more. Prices come in more and more. We're literally able to buy mortgage securities, residential mortgage securities. We're able to buy corporate debt, especially of the auto finance arms of General Motors and Chrysler and Ford. Lehman goes broke and that had pieces within its capital structure that got very interesting. We're seeing all kinds of things and we're kind of kids in a candy store. Sadly, it's a tough time, people are hurting, but also as an investor, you're a fiduciary and you've got to put money to work where you're going to benefit your clients. We're in every case stress-testing, hey, if the world got even worse, hey, if this turned out to be 1933, will this investment be okay? That's the only place where we're making decisions — if the downside is protected and if we can see lots of paths to winning, then we're very interested. The challenge in investing for everybody is you want to make sure those environments are going to happen once in a while and you need to make sure you don't blow up during them and if possible you need to make sure that you'll have capacity to buy when the best opportunities become available and maybe your competitors are sidelined. To be around on that day and be able to do what we do, we just did the same thing we do every day. We did a little bigger size.
Barry Ritholtz 27:21 ↗
I'm kind of fascinated by the dynamic tension between fundamental bottoms-up research on a credit or equity basis versus the top-down. I know you've said that you really don't think about markets or investing from a top-down perspective, but it seems that everybody who panicked, everybody who helped create those distressed assets were either responding or over-responding to the top-down environment. How do you look at that sort of environment?
Seth Klarman 27:56 ↗
There are several layers to that. People were responding to all kinds of things. They were responding to redemption requests by their mutual fund shareholders. They were responding to credit downgrades — this bond is no longer investment grade and maybe my mandate is I can only own investment grade bonds, or this bond has defaulted and I can no longer hold this bond. So you have forced selling all over the place, and forced selling is — you never want to be a forced seller and you especially want to be able to buy from forced sellers in any asset class. I think if you're going to climb a mountain you want to look bottom-up. You want to understand is this the right trail? Is this safe? Do I have my equipment? Am I prepared? And then you also want to have the top-down view. What's the weather? What if it suddenly gets snowy up there? If the wind's 60 miles an hour, how am I going to handle that? So you kind of want to have in your head the weather forecast. I'm always thinking about is this environment safe? In today's market, it feels stretched, but it also feels like we're on the brink of an unprecedented technology and an era that might be one of very substantial prosperity, but also one of risk to society and great change. Bottom-up still feels like the right way to invest, but you still need your eye on the weather in the financial markets. Where's the GDP going? What's the national debt? Where's inflation going to take us? I always have an eye on that stuff but we're not investing our portfolio based on that. Rather we notice a security bottom-up and say wow that seems egregiously mispriced. I wonder if there are more mispricings. Maybe we should look at that market a little bit closer.
