Tænkte at jeg ville dele denne meget relevante video fra Ben Felix, hvor han på fornem vis opridser, hvorfor det ikke nødvendigvis er en god idé at overvægte sine investeringer mod de hotte nye teknologiske trends.

Han er desuden også stor fortaler i Small Cap investering. Nogle af jer der har fyldt det råd? Jeg er pt 100% i large cap, men jeg overvejer at ændre

- Exciting new technologies and the companies that create them seem like obvious investment opportunities. Why wouldn't you want to invest in the companies leading a new world changing technological paradigm. Each past technological revolution has changed the world in profound and distinct ways. But their relationship with financial capital has been remarkably consistent. While we can't predict how emergent technologies will change the world, we can draw insight from how financial markets have behaved through past technological revolutions. I'm Ben Felix, in this episode of common sense investing, I'm going to tell you what to expect from investing in technological revolutions. (upbeat music) A technological revolution is a big deal. It modernizes all existing industries. Increasing the full spectrum of economic productivity. It is easy to get caught believing that today's most successful industries and companies are unlike anything that we've seen in the past. But within the social and technological paradigms of their time, past technological revolutions have resulted in unprecedented surges in productivity and growth. The relationship between these technological revolutions and financial capital has followed a consistent pattern. This pattern was summarized in a model proposed by Carlota Perez in her 2002 book, "Technological Revolutions and Financial Capital." First, there is an eruption of the revolution resulting from incremental advances and innovations that culminate in a technology with the capacity to increase the economy's productivity and the financial capital to support it. This is followed by two or three decades of the new technology being installed in the economy. The installation phase can be turbulent as the new technology divides the economy into old and new creating social and economic divisions regulatory turmoil, and wealth inequality. The installation period has historically been accompanied by what Perez calls a major technology bubble, centered on the new breakthrough technologies and spurred by the extraordinary profits produced by them. The major technology bubble is as with any bubble, followed by a collapse, the collapse leads to a re-composition of the regulatory framework that sets the conditions for the final deployment period of this new technology. The final phase consists of more organic growth in financial assets that lasts until the limits to productivity and growth from the technology are reached. Setting the stage for the eruption and financing of the next technological revolution. The major technology bubble tends to happen midway in the process of a simulation of each technological revolution. Affecting primarily the companies engaged in those technologies. This bubble like behavior of technological revolutions ultimately results in low returns for investors. These bubbles are an empirical fact in the historical data that cannot be ignored when we're talking about in technological revolutions. The surge of development in canal mania was followed by a canal bust. Railway mania was followed by a railway bust. The infrastructure boom of the late 1880s was followed by several busts. The roaring 20s ended in the great depression and the surge of IPO's in the internet bubble ended in the tech crash. The lesser known British bicycle mania followed a similar path. The concept of a bubble used by Perez is convenient and easy to think about. Investors get into an irrational frenzy about the potential for high profits from the new technology, irrational exuberance as Robert Shiller describes it. This results in prices that exceed any notion of fair value. While there is likely a contribution from irrationality to these bubble like patterns, I don't think that it would be intellectually honest to assume that investors have been consistently irrational through all past technological revolutions. I'm not saying that investors are perfectly rational, but perfect irrationality is arguably a bigger assumption. In the 2004 paper, "Was There A NASDAQ Bubble In The Late 1990s," Lubos Pastor and Pietro Veronesi show mathematically that higher uncertainty about the average profitability of the companies creating new technologies leads to higher prices or else equal. When an exciting new technology company is being tested there is a huge range of potential outcomes. Maybe it's the next Microsoft, but maybe not. The concept that uncertainty about average profitability leads to higher prices, is counter-intuitive, but it's important. We're going to do some math pay close attention. using the Gordon growth model for stock valuation where stock price is equal to expected dividends, divided by the discount rate minus the dividend growth rate the price has a convex response to changes in the dividend growth rate. This means that as the dividend growth rate increases or decreases, changes in the price are not linear they are convex. There's a special case in mathematics for convex functions called Jensen's inequality. For the Gordon growth model it implies that when dividend growth rates are modeled as uncertain, the expected growth rate required to explain a given price drops. The larger, the uncertainty about the dividend growth rate, the larger the drop in the expected growth rate required to justify a given price. Assume a discount rate of 11% and an expected dividend of a $1. If we take a stock trading at $56 the implied no one dividend growth rate is 9.2%. If on the other hand we allow for two possible dividend growth rates, 2% or 10% with equal probabilities, the expected growth rate, the average of the two equally likely possible growth rates needed to justify the $56 price is only 6%. This inequality tells us that for an expected dividend growth rate increasing uncertainty increases the price without requiring the assumption of irrational behavior. Uncertainty increases the fundamental value of a company. As the market learns about the profitability of businesses in a new technological paradigm, the uncertainty about their growth rate decreases causing their prices to fall or else equal, Pastor and Veronesi argued that in the late 1990s there was high uncertainty about the average profitability of technology firms. And that this uncertainty helps explain the high level of technology stock prices at the time. They find that the level of uncertainty implied by their model to justify the high prices in the dot com bubble, matches up well with the realized volatility of technology stocks over that time period. They conclude that the high prices of the internet boom were not necessarily detached from fundamental values when the high levels of uncertainty are accounted for. In another Pastor and Veronesi paper, "Technological Revolutions, And Stock Prices," the authors build a model where there exists a new economy and an old economy. The new economy is small and experimental until it becomes no one that it could meaningfully increase productivity in the old economy. Before the technology in the new economy is adopted by the old economy, the risk of the new economy is idiosyncratic. It is specific to the small new economy. If the new economy starts to become profitable there is a point where the combination of profits and a relatively low discount rate results in high prices. As the chances of the new economy being adopted by the old economy increase, the rise in systematic risk in both the old and new economies result in decreasing stock prices and increasing volatilities. The risk in the new economy is becoming tied to the systematic risk of the old economy. Well risk in the old economy is also increasing based on the potentially risky undertaking of adopting the new technology. When this happens, the new economy stock prices drop more and are more volatile than the old economy due to an increase in the new economies market beta. They test the predictions of their model against the dot com bubble and the railroad bubble. The dot com bubble pattern was much stronger in the NASDAQ index, their proxy for the new economy than in the old economy. Proxy by the NYSE AMEX. NASDAQ's beta doubled between 1997 and 2002. The volatility of the old and new economies increased but the new economies volatility always exceeded the old economies. NASDAQ's beta and both volatilities peaked in 2002 followed by an acceleration in productivity growth in the U S economy. In the 1830s and forties there was substantial uncertainty about whether railroad technology would be adopted on large scale. Pastor and Veronisi found that all stocks fell before and during the year 1857 with a railroad stocks falling more than non railroad stocks. The railroad stock volatility and relative prices consistently exceeded their non railroad counterparts. The volatility of all stocks Rose in 1857. The railroad stock beta increased sharply in the 1850s before falling right after 1857. Which was soon after railroads began their large scale adoption. It is important to note that the bubble like pattern in stock prices arises at least it's in part due to a selection bias. We are more likely to study technological revolutions. Once we know that they've taken place. The investors living through them on the other hand are not aware of whether the new technologies are going to be adopted into the old economy or continue as small and experimental. One of the practical implications of this insight in the context of the model is that when the stock prices associated with a new technology rise as their profitability potential becomes known, betting that they will be adopted on a broad scale is similarly a bet that their prices will decline. Taken together when a technology begins to revolutionize the old economy the market learns about its profitability reducing uncertainty and stock prices due to the convexity on growth rates in valuation theory. And risk in the new economy transitions from idiosyncratic to systematic further reducing prices due to an increasing discount rate. Whatever the theoretical explanation technological revolutions and bubble like characteristics are difficult to separate in the historical data. We always have to remember what a stock represents. A stock is a claim on a company's future profits. Investment returns do not come from a company's growth. They come from the relationship between a company's future profits, and how much are you the investor or paid for those profits? Paying a higher price should lead to lower realized returns or else equal. This is exactly what the historical record shows. In the fifth edition of Jeremy Siegel's book, "Stocks For The Long Run," Siegel offers the example of the S and P 500 index. Since inception of the index its industry composition has changed materially. In the 1950s steel chemical auto and oil companies dominated the index. Whereas today healthcare and technology dominate. Despite the decline of the originally dominant industries had an investor bought and held the original firms in the S and P 500 at its inception, they would have beaten the actual index by more than 1% per year for the next 50 years. Siegel argues that this is due to investors overpaying for expected growth. From 1900 through 2019, rail companies declined from a 63% share of the US stock market to a less than 1% share. It is the ultimate example of a declining industry. Over that time period, rail stocks beat the U S market, road transportation stocks, and air transportation stocks. Since the approximate start of the age of information in 1971, the software industry has grown more than any other firm, basically non-existent in 1971 to the largest by market capitalization at the end of 2019 at nearly 15% of the US stock market. The oil industry on the other hand has seen a massive decline in market capitalization from nearly 15% of the U S market in 1971 to about 3% at the end of 2019. Over this period a dollar invested in the oil index grew to $134. Well, a dollar invested in the software index grew to only 76. Another common assumption is the betting on the winning companies. The companies that end up dominating a technological paradigm make good investments. This is simply not been the case historically. Every technological paradigm has had winner take all companies. These huge companies make up a large portion of the stock market and drive the economy. Their stock returns though have left much to be desired. For each decade, starting 1930, 40 50 and so on through 2010, the 10 largest companies at the start of the decade have trailed the market as a whole, by an annualized 1.51% on average for the decade that followed. Bets on new industries or against declining ones have historically failed to pay off. What about the next technological revolution? Does it make sense to look for the next Apple, Amazon or Google before their prices rise? This notion is more akin to playing the lottery than many people realize. Evidence from IPOs and venture capital tells us why. Stock returns in general exhibit positive skewness. Most stocks performed poorly and a relatively small number of stocks perform exceptionally well. The positive skewness in IPOs which tend to behave like small cap growth stocks and venture capital is even more pronounced. The vast majority of small cap growth stocks produce poor returns while a few produced large positive returns. Almost two thirds of venture capital financings lose money while a tiny number of them produce huge returns. The chances of picking winners before the fact are not in your favor. Investing in technological revolutions is one of the least successful strategies in investing. Whether we interpret the empirical reality with the lens of frenzied, irrational investors paying too much for expected growth or rational investors assessing a highly uncertain future payoffs. The historical record remains the same. Counter-intuitively investing in declining industries or more generally companies with low prices has produced reliably better outcomes. But every time that a new technology or industry creates a new opportunities for financial capital investors have flocked to it with seeming disregard for the historical record and the theory predicting similar outcomes in the future.
