Nothing is impossible, but this outcome is implausible. Sure, some of the new tech giants are at valuation multiples that are not extravagant, but several sport startling multiples—and all trade at levels that require robust continued growth. These companies are at war—in some cases directly with one another—for market share, competing for the same eyeballs, and are facing a growing risk of regulatory constraints. If history is a useful guide, apple may still be in the top 10 list (but no longer number one) in 2028, and perhaps one of the others will still be on the list. History would suggest that, of the seven, at least six will underperform the market over the next 10 years. Beyond the top-tier tech favorites, a host of companies such as Snap, hubspot, overstock, and now Shopify each have negative earnings and lofty price-to-sales ratios.

Never before has any sector so dominated the minute global roster of largest market-cap companies. At the peak of the tech boom, four of the top seven companies by market cap were in the tech sector, and at the peak of the oil bubble, five of the top seven were in the energy sector. Only the japanese stock markets bubble at yearend 1989 has matched todays tech sector dominance of the global market-capitalization league tables.9 Not only do we have the fangs, we have fang futures, affording hypothesis investors a chance to buy the worlds trendiest tech stocks with almost. History shows that, on average, just two stocks from the global market-cap top 10 list remain on the list a decade later. The two survivors almost always include the number-one stock. But the number-one stock has never been top dog a decade later, ultimately underperforming and moving lower in the list. The second surviving stock has 50/50 odds of beating the market. If this history repeats, nine of the top 10 market-cap stocks will underperform the market over the next 10 years, and just one has a 50 chance of underperforming. We dont particularly like those 95 odds. Can all of the seven tech highfliers collectively succeed to sufficiently justify their.3 trillion combined market capitalization at yearend 2017?

Anecdotal stories abound of individuals looking for a once-in-a-lifetime opportunity to get ahead or to rescue their severely underfunded retirement plans (Harlan, 2018 buying cryptocurrencies because they are driven by a fear of missing out (Aslam, 2018 and paying prices only justified by extrapolating wildly. A recent survey of fintech leaders, certainly a biased sample but the essay group likely most heavily involved in trading cryptocurrencies, forecast returns for calendar year 2018 ranging from 95 to 2,920 for the top 10 cryptocurrencies.5 Pity the unlucky investor who selects the only cryptocurrency. The bitcoin bubble also serves as a wonderful example of how bubbles create harmful distortions in the real economy. The website digiconomist estimates the run-rate annual electricity utilization of the bitcoin network at 56 billion kilowatt-hours. Thats more than enough to power all the households in Los Angeles for a year, and nearly enough to meet all of Israels power demands. Bitcoin already consumes about.25 of total global electricity consumption! All just to produce new coins on a nonphysical ledger and move these coins around on electronic exchanges.6 Will we someday find that all of this energy consumption has gone to waste?7 we see a bubble in the us stock market today, albeit less extravagant. Reasonable observers can disagree, but we believe we are experiencing a tech bubble, based on our relatively rigorous definition of the term.8 At the end of January 2018, the seven largest-cap stocks in the world were all tech fliers: Alphabet, Apple, microsoft, facebook, amazon, tencent.

Those of us who are libertarians, wary of government control of the money supply, are rooting for that outcome. That said, how many investors are holding cryptocurrencies for any purpose other than the expectation that someone else will pay a higher price at some point in the future? Arguments for the future value of cryptocurrencies bring back fond memories of the price-to-eyeballs metrics used to justify the market cap of businesses such. Nonetheless, the price of bitcoin rose by 1,369 in 2017.4 even if we assume that bitcoin has merit as a libertarian alternative to government-sourced fiat currency, its hard to justify todays 1,500 different cryptocurrencies. Many of these were launched with the singular goal of making the originator of the cryptocurrency wildly wealthy in an ico (initial coin offering). Its harder still to justify the myriad exchanges, which offer only a receipt indicating the purchaser owns cryptocurrencies on their platform, many of which have been essays hacked, costing customers billions. As for the platforms that offer lofty interest rates to those who lend them cryptocurrency, little doubt exists many of these operators intend to convert your cryptocurrency into their own kleptocurrency. And now, bitcoin futures permit leveraged investments in one of the most volatile assets ever created. The speculative nature of the cryptocraze cements, in our minds, its bubble status.

In hindsight, using our simple definition, the tech bubble was indeed a bubble. More importantly, many observers in the midst of the bubble correctly perceived it for what it was (Asness, 2000). At the beginning of 2000, the 10 largest market-cap tech stocks in the United States, collectively representing a 25 share of the s p 500 Index—Microsoft, cisco, intel, ibm, aol, oracle, dell, sun, qualcomm, and hp—did not live up to the excessively optimistic expectations. Over the next 18 years, not a single one beat the market : five produced positive returns, averaging.2 a year compounded, far lower than the market return, and two failed outright. Of the five that produced negative returns, the average outcome was a loss.2 a year,.6 a year less than the s p 500. Eerily similar to the new economy dogma of the dot-com bubble is todays cryptocurrency craze. It boggles the imagination to hear people speaking of investing in bitcoin, an electronic entity that offers no hope of future operating profits or dividends, is little used as a surrogate for money in transactions (trading volume is well over 100 times as large. Will bitcoin and a handful of other cryptocurrencies settle in and become a stable store of value, akin to gold or sovereign currencies?

Over the first quarter of 2018, tesla has been an excellent example of a micro-bubble. Teslas current price is arguably fair if most cars are powered by electricity in 10 years, if most of these cars are made by tesla, if, tesla can make those cars with sufficient margin and one quality control and can service the cars properly, and. To us, that seems an unduly optimistic array of assumptions, especially given the magnitude of Teslas debt burden. Such an argument ignores the deep pockets of competitors and the common phenomenon of disruptors being themselves disrupted by newcomers. Absent the unfolding of this rosy scenario, teslas current price would require remarkably aggressive assumptions to deliver a positive risk premium. For investors who agree with this assessment, tesla constitutes a single-stock micro-bubble.3 This example also illustrates a key point about bubbles: Because the current price is acceptable to the marginal buyer and seller, there will always be a cohort that says, This is no bubble!

Sector and broad market bubbles are much rarer events. In this context, a bubble occurs in a sector or a market for which an implausible set of circumstances must prevail in order for the sector or market to collectively deliver a positive risk premium relative to bonds or cash, even though sufficiently aggressive assumptions. The tech, or dot-com, bubble is the poster child for a broad market bubble. At the height of the bubble, aggressive assumptions were required to believe the entire us stock market would deliver a positive risk premium relative to then-prevailing bond and cash yields (Arnott and ryan, 2001). For the tech sector, in particular, to deliver a positive risk premium compared to the 6 bond yield at that time, most tech stocks would have had to produce rapid growth far into the future, even though few could have succeeded unless their fiercest competitors.

True, the students in their experiments were trading in laboratory settings, not real markets, but the studies have been repeated with seasoned investment professionals, with similar results. As Smith later remarked (Altman, 2002 It took me several years to realize that the textbooks were wrong, and the people in my class were correct. More recent research shows how investor expectations around greater fools and future price movements are strongly influenced by recent market returns, further encouraging the formation of bubbles. Greenwood and Shleifer (2013) studied six sources of survey data of investor expectations for future market returns. They showed that investors behave with strong extrapolative tendencies: following periods of strong market returns, investors become used to strong performance and extrapolate it into their expectations of future market returns.


For example, a gallup survey showed that investors increasing their expected market return from 12 in mid-1998 to 16 by early 2000. By the end of 2002 this number had fallen. Under certain conditions (i.e., following times of high prices and low yields investors will raise their estimates of future market returns. Of course, this is exactly the opposite response of what a time-varying risk premium model or an even simpler Shiller pe (price-to-earnings) valuation tool would suggest. Furthermore, greenwood and Shleifer showed that investors put their money where their mouths are: mutual fund flows into the equity markets correlate quite strongly with the investor expectations captured by the surveys. Clearly, investors allow their return expectations to drift from reasonable models of fair valuation, and instead expect future buyers to pay even higher prices for stocks with already sky-high valuations, which, of course, they do—until they dont—and the market collapses. Its a bubble because, our view is that the market constantly creates single-asset micro-bubbles, isolated examples of extreme mispricing which require severe right-tail outcomes to justify the assets price.

Sadly, these hypotheses and models lack a key attribute of scientific method: they are unfalsifiable. No practical difference exists between an inefficient market and an efficient market in japanese which risk premia vary in this fashion. That said, we do have some observations on investor behavior and expectations. Vernon Smith won the nobel Prize for his groundbreaking work in experimental economics, including experiments that showed bubbles and crashes occurring in normal economic settings. Smith showed that even though investors share the same information, they do not come to the table with common expectations. As a result, even when market participants are all aware of a formula-based value for an asset, they will overpay or underpay relative to a known fair valuation. The academic phrasing Smith, suchanek, and Williams (1988) used—agent uncertainty about the behavior of others—can more commonly manifest as the self-evident presumption of a greater fool.

Prices adjust until the marginal investor becomes willing to assume both market risk and assorted factor-related risks. The markets willingness to bear these risks varies over time. In this view, high valuation levels dont represent mispricing; the risk premia just happen to be sufficiently low so as to justify the prices. These models benefit from being constructed on a post hoc basis to be consistent with market events. Fair enough, because a useful model needs to be consistent with observable data. But the models often shift problems in the observable data, such as puzzlingly high volatility in price-to-dividend ratios, into unobservable nooks and crannies. In other words, perhaps bubble-like prices can be perfectly essay rational as long as we accept curiously high volatility in the curvature of investors utility functions.

and 2) are sustained because investors believe they can sell the asset. Notably, there are markets in which few, if any, buyers care about discounted future cash flows to value the asset. In order to identify a market bubble, we need to strongly believe our definition applies. Borderline calls dont qualify. Most academics, especially adherents of neoclassical finance, will dismiss our arguments. After all, for every seller, theres a buyer—because some investors like an asset at the prevailing price, the market must be efficient! Impressive economic models, which include variants on investor utility or additional sources of risk, have been developed to allow a risk premium model to explain bubbles, crashes, and puzzles, such as excessive volatility in price-to-dividend ratios.2. The efficient market hypothesis has been stretched to fit observed market behavior, by allowing cross-sectional and intertemporal variations in risk premia.

1, the relentless rise in the us stock market since its low in 2009 has been dramatic. Us stock market valuations now exceed all historical valuation levels, except for those hit at the peak of the dot-com craze. This raises an obvious question for investors: Today, in early 2018, and has been the case over the last year, is the us stock market in another bubble? The more important question then becomes: How should investors react? We recommend four actions investors can take in response to the current bubble conditions, which should actually allow investors to benefit from the bubble. What Constitutes a bubble? To address these questions, lets begin by offering a definition of the word bubble. We all hear the word thrown around short carelessly and often, but it lacks a formal definition.

Key points, the word bubble is tossed around with abandon. We offer a rigorous definition for the word, and then test the definition against current markets. Several bubbles are evident today, most importantly a tech bubble, eerily similar to—albeit narrower than—the new economy dogma of the dot-com bubble. We also see a bubble brewing in cryptocurrencies and micro-bubbles in select stocks such as Tesla. Investors can take action to protect their portfolios and potentially benefit from the bubble by reducing exposure to bubble assets; seeking out exposure to anti-bubbles, where assets or markets are irrationally cheap; investing in value-based smart beta strategies especially in European and emerging markets; and. Finally, we must be patient. Bubbles typically continue longer than expected, until they suddenly pop. The market can stay irrational longer than you can stay solvent.
