You are a connoisseur of historical financial market bubbles. Which one, or which one is most similar to the current period that we're in?
People tend to think a bubble. Oh, it has to be somehow a conjunction, and it's exactly the opposite. The great bubbles are the biggest ideas for decades. So the only one as big as AI is possibly the railroads. Of course, everybody could see that the railroads were going to change the world. You arrived at the railway station and a horse and buggy, for heaven's sake. And, you know, you went seven miles an hour, and then you got on a train traveling at 60 miles an hour and went a couple of thousand miles. I mean, it was utterly revolutionary.
So what happened? Everybody could see that the railroads were going to change the world, which they did. Everybody wanted to have a piece of it, and they could. Everybody put their money in it. And you had the biggest bust on both sides of the Atlantic that you could imagine. And everybody lost their money in railroads. And out of the ashes, the tracks were still there. The locomotives were still, the demand was still there. And, it changed the world.
And then you fast forward to the internet. Powerful idea, clearly, by the way, accompanied by a lot of silly stuff, as well. But underneath, underneath it, a very powerful idea. To have a great bubble, you have to have decent economic times. The better off, the better the bubble. You have to have the easy money, the better and easier, etc., the better the bubble. And you have to have a fabulous idea, and you have to have it. So obviously, it's important that everybody can see it. Now, they're very, very rare events, aren't they? This one is as big as anything but the railroads. I am not even prepared to say it isn't bigger than the railroads. It may be, but they're the two super champs. Besides them, I think the internet is, you know, a bit of a piker, but they're the two colossal lots that, if ever there was a massive idea that will change, is already changing the world. It's AI. Does anyone not know that?
Hello and welcome to another episode of the Odd Lots podcast. I'm Tracy Alloway and I'm Joe Weisenthal. Joe, I have a headline for you.
Go on.
Oh, yeah. This is a good day for headlines. We're recording this June 16th.
You have a lot of headlines.
That's right. You could choose from, but one in particular. Yeah, I'm sure you saw this already. SpaceX extends gain to 17%. Set to overtake Microsoft in value. I had a feeling I think at some point, did they also overtake Amazon?
Yeah, I think all of those. Yes.
I think in the last week, I mean, we were traveling the week of the SpaceX IPO, which just captivated everyone, day after day. And there are, I am sure there are any number of superlatives. You know, at Bloomberg, we really like superlatives. You know, it's like there's like the largest gain since Exxon.
Sure. Biggest and or stats than superlatives, right?
Well, I suppose, but, there was also one I saw, I guess yesterday. So June 15th was the 500 richest people collectively, and $366 billion of their wealth is the single biggest. You know, the numbers get bigger over time. There are some, it's some big times for the market, a nice day for them. But the crazy thing about SpaceX is, okay, you have this company that's now worth $2.7 trillion or something on $20 billion of revenue from 2025. And I can't even do, you know, if we're talking about valuations, you can't even do a traditional price earnings ratio because there's no earnings. There's just sales. And the price to sales ratio is more than 100. Something like that, you know, look like I don't even know where to begin. I mean, you've seen the superlative pictures. I mean, the the argument that's being made is that, yeah, there's a lot of arguments being made and people, it's like, oh, it's actually an AI company because of all the GPUs and data centers that they've built. They really do have. And we've done an episode on this, an extraordinarily commanding lead in space and satellites and Starlink, etc. You know, the revenue is what it is. I don't know, but also, I think it's fair to say things feel a little bit speculative.
Yeah. At the moment. Right. You see a headline like that, 17%, that's, you know, overtaking a stalwart of the tech industry in the space of, it's been less than a week, right?
Yeah. I mean, you know, look, I mean, the other thing is, look, these companies like, and if we're going to get these other big IPOs later in the year with OpenAI and Anthropic, presumably they've built, you know, I mean, it's basically been around for a long time that historically companies came public much earlier, etc. So obviously, you know, it does have 22,000 employees. It's a big company, but the revenue is what it is. And if you're looking at it from a sort of like valuation based metric, you would have to say at a very minimum, investors are are you have to be banking on very rapid growth in the very short term in the coming years to expect good returns here. Right.
So obviously one of the big talking points they like, I'm looking at the page first is like, do you know where it's headquartered?
No. Actually, Starbase, Texas.
Oh, so they have their own town in Texas that they got to name. But that is their corporate info. And on the SpaceX Starbase, Texas. Well, that's definitely worth 2.7.
Yeah. So all right, the big talking point in markets is obviously valuations. All of this AI frenzy. Is it a bubble? Is it not? But even if you think that a lot of this is speculative, yeah, my big question is, what do you actually do at this point? Right? Because so much of the market has been momentum driven recently. Enthusiasm is pretty much everywhere. So we talk a lot about weightings in the indices, the benchmark indices of big tech. But also, as we discussed recently with Torsten Slok in his great presentation at our live show, like the AI factor is basically embedded in pretty much every stock at this point in time.
Well, you know, look, I, the way I look at it for my own investing in my retirement, did I very have like, sort of very boring, normally index based investing. There's like, look, I may be missing out, but these are great returns, etc. I'm not managing other people's money. You know, other like, that's a nice luxury. You know what I'm saying? It's like I have the luxury of being able to say, these are fine returns. I'm just getting from the S&P or whatever, roughly. And that's fine. It's a great year. And if like, sure, I didn't like, you know, I'm not all in on two X levered Korean memory stocks. But I'm still like, these are great returns. Had I been, had someone been paying me to manage their money, I don't know if they'd be happy to get market returns right now.
Yeah. That's right. So this poses a bunch of interesting questions, obviously.
Yeah. The big one being, are we in a bubble or not? And then I guess the next biggest one being, well, what do you actually do?
Yeah. How do you stay sane?
That's right. How do you stay sane in a giant market bubble? And we do, in fact, have the perfect guest, someone who has managed to do that over the years, more or less. I think we're going to be speaking with Jeremy Grantham. He is the co-founder and long-term strategist at GMO, as well as the author of the new memoir, "The Making of a PermaBear: The Perils of Long-term Investing in a Short-term World," and famously, "The Caller," the accurate caller of many previous markets, including .com, which is the parallel that everyone keeps using. So Jeremy, thank you so much for coming on Odd Lots.
It's a pleasure. Thank you for having me.
So what do you recommend investors to buy at this point in time? Because it seems like there's no escape from AI enthusiasm, to put it mildly.
Well, my simple advice is usually try and avoid the hype, check the numbers. And 100 times sales pretty well does the job for you. It's easy for, kind of market historians to be having a good time. These are extraordinary times and seldom been more interesting. And I'm thrilled to be alive when all the all the major issues that I have spent my life studying, and particularly the last 15 years, are coming to a head, basically at the same time. And, to find that being met by the highest priced market in history, give or take, is extraordinary. And I think in 50 years, market historians will look back and talk in all of space and read as the kind of novel slash joke it's prospectus and compare it with the stories they tell about the South Sea bubble. You know, an undertaking of such enormous value that it cannot, cannot be at this time revealed. I mean, I scooped up a lot of money and ran off with it, and they deserved it.
The naming of your book, "The Making of a PermaBear." What did you like when I read that title? Should I have "perma bear" in air quotes? As in, like, people perceive you to be a perma bear, or do you?
I voted for quotes. And oh, I probably didn't like it.
Interesting. Yeah. Because like, because I don't, you know, I know you've worn, you know, I associate you with like warning about the markets can get over their skis and understanding market history, etc. On the other hand, I look at GMO's holdings and positioning, and I see names like, you know, I do not see funds that are just overwhelmingly in treasuries and gold and say, you know, safe haven assets. I see ownership of Meta and Microsoft. This does not look like the portfolio of someone who I would think of as a, quote, perma bear, unquote.
When I was 70, I figured it was time to leave my colleagues in charge of the day-to-day decisions. I have nothing to do with the portfolio today. My only job is to study long-term existential threats to the market and society, and that includes the making and breaking of the great bubbles, which is fun because I have always, for 50 years, or at least considered the making and breaking of the great bubbles to be the only thing that really matters. The rest of the time, show up for work, keep your nose clean, you're doing fine. But the forming of these spectacular bubbles and their breaking really separates the men from the boys.
So you touch on this in the book, but when we're in the midst of a major bubble and people are seeing crazy returns like 17% on SpaceX, what do you tell clients when you know they're missing out on these huge gains? I assume you're encouraging them to be patient, to wait for that mean reversion, but how do you actually handle the pressure of having a customer, a client who is under pressure to, at a minimum, meet their benchmark with great difficulty?
It's always been difficult dealing with clients in a major bull market, and luckily we've had quite a bit of experience because since Greenspan, we've gone from one overpriced market to the next, starting with the tech bubble and then the housing bubble, and then in a sense, the end of '22 was there, the end of '21 was a spectacular, overpriced market. And now this year you've had a lot of experience. And, we were more careful at handling the clients now than I think we were in the tech bubble, where we famously lost half our book of business in two and a quarter years, actually.
Can you explain what that looks like in practice? And I understand that you're not active day to day in the security selection, but obviously people who work for you are in the very active and obviously in the client handling. What does that actually look like in practice of like, good client management at any firm?
In our case, being as honest as you can be, lay the facts on the table, make them as clear as you possibly can, try and take out 100% of the hype and kind of engage with your client so that they understand exactly how you see the market working, why it does this, why it does that, how it's in general priced. And, you know, that's a long continuous job and it keeps going in the bull markets and the bear markets. And what changes really is the client's level of excitement. They, they become careful and miserable for a while. And then excited and jumping up and down for a while. But our process of trying to deliver the facts as we see them doesn't really change much.
I think a lot of people would probably agree that markets feel a little frothy at the moment, but I think there's also a mentality. Again, it goes back to this momentum factor that's dominated in recent years. But I think there's a mentality that everyone just assumes they're going to be able to get out before everyone else. Everyone's going to head for the exits at the same time, so you enjoy the gains and then hopefully you're slightly smarter than everyone else, and you manage to save yourself before the bubble actually bursts. How do you go about thinking about timing of the bursting of bubbles? What are the signs that you actually watch out for in terms of when everyone is heading for the exits all at once?
Well, it's I have a few rules that have worked, more often than not. The one that's most interesting to me has only flashed four times since 1925. And that is that the, in the early phases of the bubble, that is, we define a bubble as a a rare two sigma event, and based on the price only. And when it breaks through that, let's assume 1928, you have a huge move. And the stocks that lead it, you know, were going up 60, 80% for the year. And then in 1929, the junky fliers start to go down. It's not that they underperform a rising market. The market goes up 35% to the peak in 20 and October. They can't even get the sign right. The previous year's leaders, the spectacular movies start to decline, and they spent the whole of '29 going down. And by the time the market broke, the S&P low price index, which regrettably was discontinued years ago, was down almost 40%. And, the low priced index where a bunch of fallen angels with enormous volatility, very high betas, and they had had a spectacular 1928 and they started to decline. Oh, why is that? I have a I have a theory that this is relates to Mr. Prince's unusually honest answer. Why is he still in the bull market? As long as the music's playing, I have to keep dancing. And that, of course, is the name of that game. But he doesn't have to go off the cliff. And Puma Tech. Puma Tech was the most advanced SPAC in '99, which was a hell of a good year to be the most advanced stock. And you don't have to go off the cliff in Puma Tech, you you go off the cliff in Coca-Cola, and that's the ideal. And that's exactly what happened in 1929. People in that case, actually Coca-Cola, they gravitated to the Coca-Cola's and the radio ads and and away from the junk, and the junk started to decline. That's an incredible signal. The greatest primal scream from the stock market ever. And nothing like that happens again. You have underperformance of high fliers, but you never had them go down in a decently rising market until, drumroll, 1972, the top of the Nifty 50. The S&P goes up 17%. The average S&P stock goes down 17%. So I can remember the numbers forever. And then we have the biggest bear market since the Great Depression. That was a truly miserable bear market, '73, '74, whether you had small cap, large cap, quality, junk, everything went down 50%. And then when adjusted for inflation, closer to 65, an absolute monster. And nothing like that happens again until 2000. In the year 2000, you may remember the growth stocks peaked horrifically in February. The rest of the S&P did not. The rest of the S&P rose about 15%. So you had a co-equal high in October. But the growth stocks were down 40%, having been as low as 50% by then. They rallied a little. And by in September, you had the S&P as high as it was in March of 2000. Just amazing deviation between the growth stocks who had been making spectacular running in '98, '99 and early 2000, and the rest of the market that continued up. And then you had a very short break the end of 2000, a steady break in 2001. And then to rub it in, a miserable -22% in 2002. And nothing like that happens again until 2021. In 2021, you may remember the meme stocks peeled off. Yeah, by the middle of the year, Cathie Wood and her portfolio were going down. By the end of the year, they were up 3,540% from their peak. And yet during that same six months, the S&P powered ahead. It's really quite remarkable when they get the sign wrong. And unfortunately, that I had an adventure with QuantumScape. QuantumScape turned out to be a meme stock without my knowing it, because I had a huge position personally. And the reason I had a huge position is that I was offered an opportunity to invest several years earlier on an all or nothing basis. I took this big position or I had nothing, so I took a deep breath. And it was much too big for our foundation, which we have for the protection of the environment, my Grantham family. And so I had to own it personally. So I was the only stock that I owned. And it was a very big chunk. And it came as a SPAC, at four times my investment. Better than a kick in the pants, $10 a share, up from two and a half. And within three months it was 131. And I mean, you talk about 131, at the end of 2020, that was the very first stock to pick out. At over 130 was bigger than General Motors. And it was the battery research lab. Yeah. They were going to design, with any luck, a solid state battery. And they still may, but they still have not got a battery on the market. So this wasn't like SpaceX, this had no sales, began no profits, and was selling for more than General Motors. Actually, I think that is more speculative than SpaceX, which I think is a very, very high ho.
Yeah, I'm glad you brought back 2021, because that was a weird year. Wild times in a way that really was. See, I would argue the 2021 was actually much more wild than right now because we don't really, you know, because of the proliferation of QuantumScapes, which was one of many stories that you could tell. You could go back to the Rivian valuation at its peak or numerous times. QuantumScape is much okay. Okay. Okay. All right. All right. Fine. But but let's talk about AI for a second because obviously we reached back towards memories of the .com bubble or 2021. But I'm looking at a chart on my terminal right now of Nvidia revenue. So in 2019, Nvidia had revenue of $11.7 billion. And in 2025, it had revenue of $130 billion. So the revenue has gone up. Therefore, I think by over 10x in six years. You know, we talk about and everybody said, oh, the very high valuations. Can't we say that the investor in Nvidia in 2019 was getting the mother of all deep value investing, given what we now know in retrospect about what its earnings were about to do?
Well, obviously, if you're clairvoyant, that's sure, sure, a deep value opportunity. Nvidia, obviously a brilliant company. And I, by the way, is a spectacular, important development. But Nvidia, the biggest piece of luck, I think I can think of in the last 30 years. You have all your money in, chips made for playing games. And suddenly it turns out that that is absolutely the right, the right design for AI. Yeah. And you have such a running start that it may take you, tell me, five years, ten years. It doesn't seem like the ultimate moat. It seems like the ultimate head start in a game where a head start is worth a ton of dough. It is worth the ten-tuple in your sales, but it's only a head start. Other people, Google, gearing up to be competitors in the next decade. Of course, there will be plenty of competition. Maybe even technologies that end-run the current type of chip. These things happen. History is full of them.
Well, can, let me just push on that again. So I take your point about Nvidia having this incredible moat from maybe arguably stumbled into the technology backwards because they were obviously in video games before. But like I'm looking at, say, even a Microsoft, 2020 annual revenue of $143 billion, 2025 annual revenue of $280 billion. So we see the biggest companies in the world doubling real business in the span of five years, which does not feel to me anything like what we were seeing. And I have fond memories of 1999 myself. That's when I got personally interested in markets. These are gigantic businesses still putting up huge growth numbers that lap Wall Street forecast year after year.
Yeah. And for the record, when Microsoft first appeared in the tradable portfolio. Yeah. For GMO, it was in our value stream. We had a value stream and a momentum stream, and we only bought the most attractive 10%. And we did that each month or 12 months. So we had 12 little portfolios, each one the best 10% for the each month of the year. And Microsoft entered the cheapest value decile and stayed there until July of '99. And that's because our value model looked at long-term future earnings and dividends projected as best we could, and we did that through projecting return on equity. And we did that by looking at how return on equity regressed to the mean and which factors affected the rate. Certain factors slowed it down, market domination, price setting that you could prove slowed it down way, way down. And Microsoft was the perfect example of this. It had very, very low volatility. It was clearly overwhelmingly the price setter. And consequently, our model said it was worth nine times book, not seven times book, but you were selling it. So you have, if you have a good value model, you can you can buy these things. You can see them on occasions coming along. And yes, it's done spectacularly well and has had then particularly a much better moat to me than Nvidia has today. But if you will allow me a minute here, please, if you look at the Magic Seven, you look backwards in history and you can say with a pretty clear conscience, each one dominates their seven different niches. They have near monopolies on a global basis. Even Tesla, you know, has a jump start, the biggest and the best for for a long time in EVs. And you have Amazon beginning to dominate retail, Google research, etc., etc. Seven decent monopolies dominating the world. Justice Department, etc. Perfectly sound asleep. No one is interested in pulling a Teddy Roosevelt. They're not going to jump in and slash and burn and divide, Exxon into seven different pieces. They're letting these things grow and, and fix and set their pricing and make tons and tons of money. And then you look forward starting from today. Does it look anything like that? Doesn't it look like seven companies deciding they're all in the same market? I write that moving the most powerfully with the greatest investment is dominant. Are they not sitting here beating their chest and saying, my $200 billion in investment in a single year is bigger than your $127 yacht? But they know how much gets paid off to the first mover who grabs the market. They all want to be the first. That can only be one, as they say in the movie. And there's seven of them fighting it out. It could be a very messy, bloodcurdling game. I suggested that they have it outside the White House, and still think, what a comparison. Just imagine ten years from now looking back and saying you couldn't see the difference between seven easy monopolies and a dogfight of seven vicious, rich companies. Huge cash flow, huge understanding of the virtues of being dominant, all deciding at the same time to fight out in one market. And you could say, yes, there was the cloud. What about that? And the cloud was a nice, well-behaved oligopoly, three of them gently deciding to compete in genteel ways. Exactly the right thing to do if you find yourself in that position, and clearly not the approach that is being adopted this time. We have seen huge investment. You look back, that idea heavy, capital light. You look forward. Let's hope their idea heavy, but they are capital heavy this time. It's like a watershed in almost everything that matters between the past and the future. And nobody seems to be talking about it in that way. And I don't get it.
The dot-com bubble has come up a number of times in this conversation. Do you actually have a preferred historical analogy for the situation that we're facing now, because we've been through technological revolutions associated with speculative manias before, ranging from, I guess what I would say are pretty real ones, like the railroad bubble and, yeah, and the internet. Yeah. To kind of crazier ones, like we're all going to go deep sea diving. Yeah, totally. And get rich that way.
You are a connoisseur of historical financial market bubbles. Which one, or which one is most similar to the current period that we're in?
So people tend to think a bubble. Oh, it has to be somehow a conjunction, and it's exactly the opposite. The great bubbles are the biggest ideas for decades. So the only one as big as AI is possibly the railroads. Of course, everybody could see that the railroads were going to change the world. You arrived at the railway station and a horse and buggy, for heaven's sake. And, you know, you went seven miles an hour, and then you got on a train traveling at 60 miles an hour and went a couple of thousand miles. I mean, it was utterly revolutionary.
So what happened? Everybody could see that the railroads were going to change the world, which they did. Everybody wanted to have a piece of it, and they could. Everybody put their money in it. And you had the biggest bust on both sides of the Atlantic that you could imagine, and everybody lost their money in railroads. And out of the ashes, the tracks were still there. The locomotives were still, the demand was still there and, it changed the world.
And then you fast forward to the internet. Powerful idea. Clearly. By the way, accompanied by a lot of silly stuff, as well, but underneath it a very powerful idea. So you had Amazon go up six or seven times in '99, and when the market broke, it went down famously, infamously 92%. Check it, 92%. And then it rose from the ashes, just like the railroads, and inherited the retail market more or less.
So you have to be, to have a great bubble, you have to have decent economic times. The better off, the better the bubble. You have to have, the easy money, the better and easier, etc., the better the bubble. And you have to have a fabulous idea and you have to have it. So obviously, it's important that everybody can see it. Now, that's very, very rare events, aren't they? This one is as big as anything but the railroads. I am not even prepared to say it isn't bigger than the railroads. It may be, but they're the two super champs. Besides them, I think the internet is, yeah, a bit of a piker, but they're the two colossal lines that, if ever there was a massive idea that will change, is already changing the world. It's AI. Does anyone not know that?
I think everybody knows it. Does anyone want to put their money on it? I think SpaceX, etc., gives us a pretty good idea. 90% of the value, if you read the perspective prospectus, is based on AI, even though that particular AI seems to be having its bottom kicked by two or three others, as we said, but wouldn't let facts get in the way of a really good story. And, this is an absolute classic. It checks everything off one after another, which haven't been checked off many times in history. So this is it. If you think this is not a bubble, you are going to be in for a bit of disappointment.
How do you channel in your book, you talk about how competitive you are and growing up and wanting to play all different types of games. How do you channel competitiveness in a productive manner career-wise, so that it doesn't hinder you or it doesn't make you chase performance? Or does it make you worry about one year's performance versus the, one another? Competitors like, how do you, how do you make the competitiveness instinct be a good thing?
I think try and bring it to bear on a few areas that that matter to you. Starting with obviously the most important, playing a decent game of doubles and tennis and, every point has to be played as if your life depends on it. And you pick partners and opposition who who do the same. And you have a wonderfully good time. And then you look around for other things. And for me, it was ideas. And I could have made a lot more money if I focused on profit maximizing. But for me, the idea was the dominant idea and sorry, principle. And and the idea of being competitive was everything hinges on trying to outthink the enemy. The easiest way for me, it always seemed, was to be longer and wider and more comprehensive and and stand further back than the other guy. And what you quickly realized when you do that is that no one else is even trying. So this is not a fair fight. Everybody is focused on the near term. And if you want to profit maximize, that's not a bad idea. And very few people are attempting to be in the market and simultaneously asking questions that are several years out and, and even to some extent a decade or two. And, so it's been very easy for me to be both competitive and, and cheerful and, and often wrong, since we're talking about career development now, I suppose.
Is it important when you're a perma bear, or more accurately, when you're perceived to be a perma bear, to distinguish yourself in some way from other bears who are out there? Because, again, at this particular moment in time, there are a number of high profile commentators who would say that AI is a bubble. So how do you actually stand out from, I guess, the bubble calling crowd?
Yeah, I have no idea. My I have only made two unmitigated, bullish calls. The market has a really hard time telling the difference between, hey, this is overpriced. This is going to make you less money over the next 20 years than it would do if it was half price. There's just kind of mathematical realities. And because you say that they, oh, you said the market was going to collapse. You have been bearish forever. Now, when I want to be really bearish and recommend you get out of the market, I say so. And I've only done that twice. On July the 15th, '08, July the 15th, 2008, I wrote a quarterly letter which basically which actually said, abandon ship, sauve qui peut, the French equivalent, and actually quoted the nursery rhyme, don't be brave, runaway, live to fight another day. I do not take any risk. You don't have to take. We all have restrictions on how much we can get out of the risk-taking business. But do not take anything you don't have to. Okay, I was pretty clear. And, the last thing that we had been bullish about was emerging markets. And I said, I've changed. Changed our mind. We think this is the end of the line. Sell any emerging that you can. And we did the biggest trade that we had ever done getting rid of the last of our emerging. I must say, shortly before we published a letter.
What year was the, the 2008?
Okay. Yes. And may I say that following that, in four months, the emerging market halved. I think it was the biggest, sharpest decline in the history of any major index from July the 15th to November the 15th, and actually slightly before that. The, the whole index halved. And and the other bearish one was at the end of 2021, where the quarterly letter was called "Let the Wild Rumpus Begin." Right. That meant now get your tail out about the market. I'm happy to say S&P went down like a rocket ship, -25. Growth stocks down 35. Mag Seven down 40. And the bond market had the worst year in the history of the bond market. And then, as I also like to say, my nice bear market was rudely interrupted by got JP and and the economy that was doing its usual thing of, of gracefully moving into a mild recession because animal spirits were going down, was also changed by massive and increasing CapEx spending on AI, which dragged, kicking and screaming, the animal spirits of the rest of the economy. They didn't change easily, by the way. Yeah, the S&P, the rest of it went down for another ten months, but they kept going so powerfully in the market and so powerfully in the CapEx business that they changed the game. That's only happened once in history, and I don't know how to predict things like that anymore. Then COVID, and new things are a pain. And, there aren't happily many of them, but they're the two most interesting ones in my career. COVID was novel. How do you treat novelty? If you're a historian, you don't. You have to work it out on other principles. And this AI interruption of what was a perfect, perfectly ordinary and I thought predictable bear market because it it flagged my great discrepancy between the market leaders going down as the blue chips continued up. How do you do that? I don't know.
Yeah, this is really striking. You know, we recently, we had Torsten Slok at one of our events talking about, you know, the sort of imperviousness of the AI trade to what traditionally we would call macro. And so what you describe, you're like, okay, here comes the expected, as you said, probably would have been a shallow recession. And now we see this investment. There's capital expenditure. There's completely they couldn't it does not seem like, the companies care at all about the fact that the Fed hasn't cut rates as expected, etc. These classically macro indicators that we did a recession, business cycle, etc. had just seemed to be blown out of the water, yet blown out of the water by the AI.
It. Yeah. And and I must say, the overwhelming interest in interest rate and interest rate predictions has left me, totally cold for the last 50 years. I, I, I leave that to other people. I think it's in general wildly exaggerated. I've lived in a world where for 50 years, the increasing debt to GDP ratio of the US economy, the Japanese economy, and every other economy has been predicting imminent collapse, and the ratio has gotten higher and higher, and then it's predicted double collapse, and it still keeps rising. The only function of, of interest rates is that it makes debt easier to acquire. And the function of easy acquired debt is that it helps the economy. One little problem. If you go back to Alan Greenspan, you find that before he got that, there is a very, very slow increase in debt to GDP ratio, just because the financial business is becoming more complicated. And then after him, it rises at 45 degrees and it goes from a small fraction of GDP. If you throw in all that, it triples and quadruples. And, and it does it over, you know, 30 years, you have the biggest economy in the world, 30 years to test what happens, quadrupling of the debt to GDP. And the growth rate goes down. So how can that be a real mover of growth rate when you've had that wonderful macro test seen from looking back over 40 years, huge increase in debt, decrease in GDP growth rate. Very strange. So I leave all that stuff away alone. If you will let me back up. Two I was saying two clear. Get out of the market cause plenty of the market's overpriced. The market has been overpriced since 2000. I admit it, it's been overpriced and we have said so the whole time because looking back at the 20th century, the 21st century has been overpriced. They used to sell at 15 times earnings. We have been selling at 23 times earnings. That is not a small fraction of an increase. It has been a different world, the 21st century, but based on history, it's been overpriced. And and of course, it still is. But I have made two bull calls in my life. The only time for the first ten years we got quoted was in something called the Wall Street Letter. Long deceased, I think it was a attach to the Wall Street Journal, and it was a weekly kind of gossip thing about the industry, and they're hidden in the tail end, actually, of that letter, is my first opportunity to quote. And it's, July 82nd, and the PE of the S&P is seven times. And I say, I think we're close to an unprecedented rally in both the stock and the bond market. And I've always been thrilled to get people copies of this year's letters. And then the market shoots up. And we become more careful for a long, long time. And then finally the market comes down in '09. And by a miracle that only occurs once every two lifetimes, we published a letter. One pager. Only two of those were done in my career of 30 years. Letter writing. And, it's called "Reinvesting When Terrified." And I think is is the best thing. I wrote mainly because it was short and it just said that you won't call the bottom of the market, you know, don't bother with that. Don't even try it. Just concentrate on the fact that the market's gone. It's cheaper than it's been for 22 years. It's even on a seven-year forecast, you're dealing with 12% a year compounded returns. And the S&P equivalent to a higher numbers in emerging and foreign equity. Get together a plan. Take it to your committee. Any plan is better than no plan. You have got to start recycling your money back into the market. And the good news is, as far as I'm concerned, it only counts if you wrote it. Yeah. Saying it is too peripheral. It gets washed away into the ether. But I wrote it and we sent it to the Wall Street Journal, who didn't get back. And, and day by day, four days passed until my advisor on propaganda and I decided, the hell with this, let's post it ourselves. And because of that delay, we posted it the day the market hit its low, 666 on the S&P 500, less than one tenth of where it is today.
Oh my God. This has been a bull market. Well, thank you for reminding two podcasters that it only counts if you wrote it.
No, it's good. We should be fair. We do write some stuff. So there is that. Could I just spend some talking? I sympathize with. Can I just go back to you were talking about how investors seem to have, to some extent, become more comfortable with higher price to earnings ratios now versus, say, for much of the last century when it comes to value investing. We all know that value has been losing recently to momentum. Does it feel at all to you that something has structurally broken in the sense that investors are much more focused on price nowadays? They're much more focused on short-term gains rather than longer returns. And at the same time, you've had a lot of retail money flow into the market courtesy of, you know, new platforms, Robinhood. And whenever I think about Robinhood, I think about clicking buttons. And remember they used to have the animation. When you would like celebrate, if you choose to trade like that's a lot of new money coming into the market that potentially thinks differently to the way investors for much of the 1900s actually saw it.
I think in every bubble, it gets very much like this. And you said, much more focused on price. Not in the sense that they're looking for bargains, much more focused on momentum. Right. That's what I mean. The price rises rapidly and and they like it and the value is irrelevant. This is, you know, this is what happened in the South Sea Bubble and this what happened in tulips and in what happened in the railroads. And that's what happens in the Nifty 50 and the tech bubble. It's what always happens. This is not remarkable, by the way. This isn't even spectacularly overpriced compared to Japan. Japan is the mother and father of all bubbles. In 1989, it sold for 65 times earnings. And if that doesn't make a value manager wake up in the middle of the night screaming once in a while, nothing will. Because, you know, we we went up finally to 35 times earnings and the tech bubble, never having been over 21. And that's a pretty spectacular jump. But Japan had never sold over 25 times earnings and went up to 65. And, I'm happy to say we survived that quite well through, through good luck. And the good luck was that international investing had only just come in and we were selling people their first international portfolios that they had ever had, including Harvard and Yale. And, I did a quite remarkable, by the way, how slow the US was. Scotland and so on had been doing this, foreign investing for a long, long time, but not it was not fashionable in the US. And, because of that, no one had was comparing international with an international index. It was only 2 or 3 years or 2 or 3 months that they had had an international portfolio. They were comparing it with the S&P because all their competitors were still in the S&P. And and the novelty that was betting international against the S&P. And it was winning. The international was so far ahead that we could underperform because of Japan. And we underperformed by ten points a year for three years. And we lost no business at all. And we had a decent market share. And then of course, Japan broke. The lesson from Japan is pretty clear. The biggest bubble in the history of the stock market, up an important stock market, second only to the land bubble in Japan of coincident, more or less coincident timing. And, what was the price you paid for having it go from 25 to 30 to 40 to 50 to 60 to 65. And the Salomon Brothers team went around at 60 to 65, explaining that the bond rate in Japan was so low it should be 100 times. I am not kidding you. I'm not getting it. And, what is the price you paid? Last 20 years? Really not ten years. 35 years have to go by before you get back to a high. And I don't think even that is adjusted for the modest inflation that they had. I mean, you want to have a bigger bubble and a better bubble, go ahead. Just be advised that the correlation with a longer and worse decline is pretty well one.
You know, we could talk for another hour just on international. All of these things. But I have one last question. You know, you're known for having a lot of, personal sort of like other interests besides investing, particularly related to the environment, climate change. You talk about, you wrote a letter, I believe, last year about, plastics and other forms of, like, dangers to the environment. Do you have any optimism at all that AI, in particular, will be of a service to humanity in tackling some of these concerns that you have about, sort of, ecology and so forth?
God, I wish I knew. The spectacular thing about AI is the degree of difference of opinion. You know, often you find that the rank and file have one view and the hot shots who know the most have a different view. But this is not like that. This is you have Nobel Prize winners who disagree violently. You have real experts who've studied it for 30 years who disagree violently. Yeah. You have the rank and file with as much experience as they could have who disagree violently. There is simply no agreement on the future of AI. It will even make us all incredibly rich, will sit on the beach and be served by robots, or the robots will go one step further and get rid of us inadvertently or deliberately. This is not bad. This is the ultimate complexity that one has ever heard, and you cannot possibly know what is going to happen. You can only plan for a wide range of outcomes. But we know for a fact that it shows up enormous amounts of electricity. We know for a fact that that is associated with an awful lot of carbon dioxide production and real pressure on the environment. So we start knowing that it will be tough. And by the way, you make robots every 20, every 20 minutes. These humanoid robots have to go off, take a coffee break and plug themselves in. Yeah. Then they will run through energy like we have no idea. Hey, we
can hardly support the energy demands of of current AI. Confined to your laptops. The energy demand of having machines running around will dwarf that beyond recognition. We will have to have multiples of the global energy production that we have now. We are simply living beyond our means.
You know, the real experts who studied for 30 years say we need 1.7 planets to maintain the current level of income, in a sustainable way. And if we want to live like Americans, we need five planets. And, I, in the best of all possible worlds, might help address this, but it's hard to imagine AI becoming self-aware and being better at everything than we are. It's hard to think of an example, as Geoffrey Hinton would say, where a smarter civilization, a smarter species, has been dominated by a comparatively stupid species. We we somehow implicitly rely on that benevolence. We're not spending that much time and money trying to design a benevolent AI. We are spending money trying to design a more powerful, competitive devil take the hindmost type of AI. It's inherited our style.
You know, humans have been the survival of the fittest. Grab what you can. Why you can. Don't worry too much. About 3 or 4 years from now, I find that exactly the same, in corporate America and capitalism, by the way, we don't act as if we value our grandchildren. We play soccer with them at the weekend, as I like to say. And we help pay the school fees. But then we go back to work for a chemical company or fossil fuel company and act as if we mean to kill them all. It's a strange nature, except it's the same as every other species on the planet. Grab what you can live for today.
And, and here we are doing the same. But something we all recognize is a bigger danger than anything we've ever met before. Living with a with another intelligence. Yeah. God, it's going to be inevitably much more than we are. And, and we are left, you know, worrying about peace. When what? When the survival of our species is at stake, when our, strangely, our climate is going to hell. Not as we used to think in 20, 30, 40 years. But now, our baby production is going to hell. Not as we used to think, in 50 years or 100 years. But now, no. China is producing fatality rate of one. A baby production that every 30 years has. That in 90 years is an eighth. And Korea is is a third of its baby production each 30 years, a ninth in 60 years, a 27th i.e they're out of business in a single lifetime unless it changes and it has been changing, but it's been changing steadily for the worse. 65% of all countries are below replacement and quite a few like China, way, way down towards one and nobody cares. We are not programmed to worry about long term slow burning problems. And they're all coming to bed together and they're compounded by ignorance or lack of concern about the risks of AI. This was going to be a very exciting time. Exciting, terrifying.
Also, if we did five planets, I think he just made the case for space. I was just going to make the same joke. Oh my God, yeah, I shouldn't have let you. I shouldn't have let you go first. There's another way to resolve that, though, and that is to have a billion people and not eight or 10 or 12. And the interesting thing is, if you asked a society to please have fewer children when they wanted more, you wouldn't have a prayer, unless you used force. But we are going to have a dramatic, sustained drop in our population by sheer luck. We are the first generation in history who are deciding to have two perfectly good reasons. 100 good reasons. We have decided to have fewer children. And if we keep doing this, we go out of business. It's quite simple. If you don't have 2.1 healthy, well-educated children, you're on your way out and almost nobody does. In the developed world and even in sub-Saharan Africa, baby production is falling like a stone. It's just falling from a very high level, falling from seven babies per mother to four. They have lost more babies over the last 50 years, and Europe has. It's just that they've lost them from a much higher level.
All right. We're going to have to leave it there. But Jeremy Grantham, thank you so much for coming on. Odd Lots. Oh, thank you for allowing me at least two minutes to talk about serious stuff. Joe, I love talking about historical bubbles. Yeah, me too. And I guess I should shout out some of our really old episodes on very esoteric bubbles. Yeah. Florida Latin, always fun. The catfish bubble. I did think the point about the change in the mag seven stocks. Yeah, this sort of watershed moment, this idea of a cage fight. Yeah, on the White House lawn and, I guess a change in corporate strategy where everyone is really tackling the same area of business. Yeah, that was interesting. No, it's super interesting. Like, you know, ten years ago, you could draw a very clear line between what Google's business was and same methods business. Right. You can't do that to the same degree when both of them, you know, meta. They're not right at the edge but they're trying to they want to be in the game as like a model maker. They're also spending and both spending enormous amounts of money on capital expenditures. And so we're like, they really are like no longer the sort of dominance of their verticals. But I have to say, like his conversation there at the end and he's like, well, will the robots be our butlers on the beach? Or will they accidentally kill us? Or will they purposely kill us? Or will humanity extinct ourselves because we would stop having having babies? Like, yes, it sort of does make you you're like, why are we wasting time talking about P ratios? Like when these are like the big questions that we're like right up against? Yeah. Like, why are we talking about ratios ever? How do I prep my portfolio for robot discussion? Very important is like the is Kevin Warsh going to cut at his first interest rate. Like that will not very likely be a particularly important question or moment. You know, ten years from now. Like that's probably not what's good. Anything will hinge on that in the grand scheme of things. That's true. But again, this sort of goes back to the big tech argument. But if you couch everything in existential terms, then you can justify anything, right? Which is what we're seeing right now in big Tech. I realize I just, naturally went from talking about the extinction of humanity back to big tech valuations. So, yeah, I apologize for that.
You know, it's interesting. You know, we did that episode about the history of rope, recently. And you know, that book, he and he made the point on the podcast that, you know, we went for about a million years. Maybe not. I don't know if it's humans, but maybe right before humans. Well, there was literally one invention, and that was the hand ax. And then you think about, like, in the last few years alone between ChatGPT and GLP one, that EVs, etc., and Jeremy is making that point like history was a little bit boring. You know, the 1950s like, oh, Coke opened a new factory and that was news. And now like and what that means is literally and, you know, other people have said this like, time is speeding up, like they're just more events per day happening. Joe. I'm tired. I'm tired. But it's good for the news business. It's not so good for our producers.
