In this episode of A Value View, The Merchants Trust's Simon Gergel, Andrew Koch and Richard Knight explore what previous market bubbles can teach long-term investors. Genuine technological change can sometimes lead to excessive enthusiasm, clouding the judgement of even risk averse investors. They consider how the fear of missing out can draw investors towards the crowd, and why many investors fail to identify bubbles before they get left behind. The team also discuss the opportunities that can emerge when capital becomes concentrated around a dominant theme. Rather than trying to predict wh...

Simon Gergel, lead manager of the Merchants Trust, discussed how market bubbles arise from human nature and the challenge of spotting them in real time. He noted that while some bubbles are obvious in hindsight, it's hard to call them in advance, citing the 1840s railway boom where investments required a tenfold industry growth but only doubled. Gergel emphasized that bubbles leave opportunities in overlooked areas, like 'old economy' companies during the TMT bubble. He advocates focusing on cash flows, sensible valuations, and long-term horizons, leveraging the trust's permanent capital. He advises following the money, buying into streams of cash flow at attractive prices, and maintaining patience, as markets often neglect value areas. He also highlighted that short-term thinking creates opportunities for value investors.

Key takeaways

  1. The 1840s railway boom required tenfold growth in five years but only doubled, showing overvaluation.
  2. Value investors can find opportunities in areas neglected during bubbles, like old economy stocks in the TMT era.
  3. Merchants Trust's permanent capital allows patience to invest in undervalued businesses with strong cash flows.

  1. 0:28And how do you avoid getting swept up when everyone else seems convinced they found the next big thing?
  2. 1:17But at the time, is it so easy to observe, so easy to see?
  3. 6:05... Simon, does it surprise you that the investment community, that those that are thinking about this subject all the time, that those lessons aren't learned, or is it impossible to learn the lesson for something that's constantly changing?
  4. 10:02Well, it's this I suppose it raises a bigger question here around patience and is that one of the few competitive advantages really that are left, would you say Andrew?
  5. 12:33What are the lessons they should be taking from that, Richard?
Andrew Kosh 0:00 ↗
I would say in investment, valuation is always important. Stories don't pay your pension.
Simon Gergel 0:05 ↗
There can be an over self-fulfilling prophecy, a virtuous cycle that's spun too fast.
What we tried to do is just stand back from that and say, look, if everyone's going over there, there may be other areas that are being left behind.

Hello and welcome to a Value View from the Merchants Trust. I'm John Cronin and in this episode I'm joined by Simon Gergel, lead manager of the Merchants Trust, together with fellow portfolio managers Richard Knight and Andrew Kosh. Now, every generation seems convinced it's living through completely unprecedented times. Whether that's the rapid expansion of the railways in the 19th century, the dotcom boom, or today's excitement around artificial intelligence, AI, history shows that markets can become captivated by a single big idea. But what can investors learn from those moments? And how do you avoid getting swept up when everyone else seems convinced they found the next big thing? Simon, Andrew, Richard, great to have you on the show.
Simon Gergel 1:15 ↗
It's great to be here, John.
Richard Knight 1:16 ↗
Great to see you. Thank you.
John Cronin 1:17 ↗
Well, it's a fascinating subject that we've got coming up and I guess the first thing I want to explore really is, do bubbles always look obvious in hindsight? And let's start with that simple question, Simon. Looking back, is it easy to point to a moment like the railway boom or the technology bubble and say that that is a bubble? But at the time, is it so easy to observe, so easy to see?
Simon Gergel 1:44 ↗
Yeah. Well, I wasn't around for the railway boom, but I was there for the technology bubble. I think it can be sometimes. Sometimes I don't think it is because you see huge genuine changes in society and massive opportunities, and it's hard to know quite how valuable they're going to prove to be. But other times you see enormous investment going in, enormous excitement, perhaps over excitement in share prices. Sometimes excess leverage, cases of people who know nothing about the stock market getting involved. So there are times I think when you can see it in advance. But it is quite tricky to know quite how far enthusiasm for a theme or an idea is going to go.
I think bubbles are a natural part of financial history and the whole capitalist system. Stock markets are wonderful things because they allow a pooling of capital from a very broad range of sources. But the downside of that, the great thing is that new technologies can be funded, society can be changed by, well, if we go back to the 18th century joint stock companies, later canals, 19th century railways, then the information technology bubble, and then of course TMT at the turn of the century. You could even call elements of the great financial crisis the property bubble before then. But what we're seeing there is the flip side of a lot of people being brought together for what starts as a very, very good idea and may create lasting benefits for society. Well, absolutely the railways did in the 19th century, as did the TMT bubble, leaving this fantastic infrastructure for us. But there can be an over self-fulfilling kind of prophecy, a virtuous cycle that's spun too fast, that leads to an overinvestment in that capacity, in that new technology, an overexuberance. And markets are very, very psychological. So of course everyone starts moving in the same direction. People get left behind. They feel the need to move in the same direction and ultimately you get misallocation of capital. I think that almost every bubble looks obvious in hindsight. The really interesting point is whether they look obvious in foresight, in advance. And what's interesting when you read about historical financial bubbles is that most of them do. It's just that the participants can't really quite work out how to get off or where it will actually stop and so they get carried away with a sort of their own momentum and sometimes that means they ended up believing very, very, very optimistic analysis. Other times they're just, they're right about the change, they're wrong about the time frame. I think in the 1840s, in order to justify the investments that were being made in Britain to build the railways, you needed the industry to something like multiply by a factor of 10 in 5 years between 1845 and 1850 and in reality it doubled. Now a doubling industry is very, very exciting but that wasn't enough to generate a good return for the people putting their capital in in 1845. So it's asking almost to predict the future to sense when a bubble is about to happen and to call it, I guess, which is a tough call for frankly anybody. But a simple question to you and Andrew, let me come to you on this, why does it keep happening? You know, bubbles don't just happen occasionally, the history of them...
Andrew Kosh 5:15 ↗
Human nature doesn't really change over the centuries, so greed is a powerful driver, particularly in financial markets, and the other side of that is fear, and when fear starts to come to play then you see these absolute collapses. It's partly the fear of missing out, seeing other people doing well, the excitement, the want to be part of something, not wanting to stand out and be different. It's psychologically hard to stand apart from the crowd.
Simon Gergel 5:44 ↗
Right? So that's as simple as that. It's human nature. Even more powerful than greed and fear is wanting to belong, is wanting to be part of, you know, a group that's all saying something reasonably similar. We all feel it in our own lives in different ways. We don't want to stand out too much. Being a value investor is about standing out.
John Cronin 6:05 ↗
Well, this is, I mean as investors, you're professionals, you've a great deal of experience. I mean, Simon, does it surprise you that the investment community, that those that are thinking about this subject all the time, that those lessons aren't learned, or is it impossible to learn the lesson for something that's constantly changing?
Simon Gergel 6:24 ↗
I think the problem is there is so much money chasing these areas that if you don't participate, that money will go elsewhere and somebody else will facilitate that. So I think what we tried to do is just stand back from that and say, look, if everyone's going over there, there may be other areas that are being left behind that might be opportunities where we can have a lot more confidence in the cash we're going to get back, the return we're going to get on investment, the dividends we're going to earn from investing in these companies, the assets we're buying on behalf of shareholders. So, you know, I think one of the great things about having an investment trust like the Merchants Trust is we've got permanent capital from shareholders. We can and a board who will back us to say, 'Okay, I can't really be sure about that area over there, there may be a great opportunity, but in this area here of the stock market, even though it's out of favor, there's some really strong businesses trading at incredibly unusual valuations. And if we buy them at those levels and hold them for four or five years, we should make a very good return and generate a good income stream.' And so we're not necessarily trying to call whether the bubble is right or wrong or whether that theme is right or wrong. We're trying to make money on the things that we understand. And so bubbles are fascinating, but often what they leave behind is opportunities elsewhere. And that was the same in the TMT bubble. There were many what were called old economy companies at the time, if you remember, most of which are still thriving today, which were being offered for well below what they were really worth.
John Cronin 7:52 ↗
So there are, I guess what you're saying, opportunities before a bubble might burst and certainly afterwards, but they present opportunities for the value investor either side.
Simon Gergel 8:03 ↗
Yes. I think if you focus on what you understand and the cash flow you're buying into and you're buying at a sensible valuation and if that cash flow is sufficiently robust and you know you understand what the businesses do and why they deserve to exist, you can keep doing that and make a good return without having to worry about an area that's actually very, very hard to analyze.
John Cronin 8:27 ↗
Richard, what happens after all the excitement fades? You know, the bubble perhaps has burst or changed direction or whatever it might be. Sentiment changes. What happens next?
