The Social Good of Bubbles – Part II

Written by Tiffanie Bederman (LinkedIn profile)

In my last post I discussed the need for a concrete definition of “bubble” if we’re to use the concept for trading/investing (as opposed to cocktail party hyperbole) and listed a few famous bubbles. These so-called bubbles (here I’m using the term to imply a rapid increase in price and a subsequent, dramatic decline) can roughly be attributed to three sometimes concurrent causes:

New/Unexplored Frontier or Industry

  • South Sea Company
  • Railway Mania
  • Automobile Manufacturing
  • Tech Bubble/Dot-Com Boom

Enabling Financial Conditions or Innovation

  • Tulip Mania
  • Railway Mania
  • Beanie Babies
  • Subprime Mortgage Crisis

Fraud or Morally Questionable Business Practices

  • South Sea Company
  • Railway Mania
  • Black Tuesday
  • Tech Bubble/Dot-Com Boom
  • Subprime Mortgage Crisis

Good Bubbles

From this framework, we can see that some bubbles are the natural byproduct of an emerging industry. With the exception of the South Sea Company – who’s original intention was to reduce the British national debt under the pretense of exploring the new world – all of the bubbles in this category created or revolutionized an industry.

Railway Mania created a vast network of tracks across the UK. Automobile manufacturing created the industry we know today – you’d never drive a Duryea (the first company in the US to build gasoline fueled vehicles), but four years after they got their start, Oldsmobile started building cars as well. In the tech bubble, everyone loves to remember who’s IPO in 2000 raised $82.5mm, but let’s remember that Amazon’s* IPO had been just a few years earlier in 1997. At $18/share they had raised $54mm. One sold dog food over the internet. The other sold books.

In nascent markets, valuations must be based not just on a company’s future performance but also on estimates of the entire industry’s growth and the company’s ability to perform in turbulent, continuously evolving conditions. When looked at holistically these valuations can reach exorbitant levels that can perhaps be attributed to hubris – market participants all believing *their* horse is the winning horse.

Price > Intrinsic Value ≠ Bubble

According to Shiller, “Gold itself is a sequence of speculative bubbles, starting in ancient times, and still continuing after thousands of years.” Proponents of gold will likely want to argue with this assertion, but consider for a moment that less than 15% of gold mined goes towards fabricated products. Out of the ~$7.7 trillion of gold ever mined, over $6.5 trillion is either held as an investment by central banks, institutions, or individuals or held as jewelry, so let’s stop claiming that “gold has industrial applications” when estimating its value. Gold has value because people have decided that it has value.

For those who disagree with my gold analysis, consider the slightly more complicated diamond market. According to a 2011 report published by Bain, “Per carat, the cost of mining a natural colorless diamond runs about $40 to $60, and the cost to produce a synthetic, gem-quality colorless diamond is about $2,500.” Cutting a 1 karat stone costs between $10 and $100 (linked article provides a good breakdown of the market). Ultimately, these will sell for anywhere from $1k to over $20k, depending on the four C’s, GIA registration, retail outlet (Tiffany’s vs, etc.

Other examples of similar stores of value are gemstones, geological findings, baseball cards, collectible coins, antiques, classic cars, stamps… the list goes on.

No sane trader would short gold or diamonds or collectibles based solely on these analyses. As a post-barter society, we’ve agreed to use objects as stores of value, gold and diamonds included. Cash objects store agreed upon values directly translatable to dollars, euros, etc. History, though, reminds us that cash objects are not the equivalent of money – just ask anyone who has old lira or 500 rupee notes stashed under the floorboards. Bank accounts are arguably the most literal definition of stores of value. The bank gives its customers space in their databases. Customers give the bank money with the expectation of being able to get at least the same amount of money back in the future. But I digress.

Thoughts on Current Markets


As of January 23rd, 2018, there are 1,476 cryptocurrencies listed on for a total market cap of $526 billion. For traders who believe that cryptocurrencies are a bubble, the more interesting question they should be asking themselves is “what type of bubble is this?” Is the emerging industry the cryptocurrencies themselves or is it the much broader category of blockchain technology? More specifically, recalling P2P e-commerce, are cryptocurrencies simply the Beanie Babies of blockchain, or are they more like the tech bubble producing some huge winners and a plethora of losers? Which one(s) are Amazon and which ones are Additionally, will financial regulations enable the development of the market or will new regulations stifle cryptocurrencies?

My opinion: the intrinsic value of cryptocurrencies is not dependent on traders or investors watching financial markets from the comfort of their home or office. It also should not be dependent on Silicon Valley trying to circumvent financial regulations. The value of cryptocurrencies lies in their ability to store value when surreptitiously crossing borders or when compared to currencies going through phases of hyperinflation (would you rather own Venezuelan bolívares or Bitcoin** for the next 30 days?). It’s for travelers who’d rather pay exchange rates and transaction costs than carry large sums of cash, it’s for refugees, it’s for criminals, it’s for individuals who want to electronically send money immediately when the Fed wire is closed. Perhaps someday we’ll be able to get rid of our bank accounts and buy a car at a dealership with Bitcoin but for an immediate investment thesis rather than a science fiction novella I have to assume this isn’t the primary use case.

The Stock Market and Credit

With financial news labeling the stock market a bubble one has to wonder what type of bubble we’re in. Given the known universe of stocks, it can’t be a new or unexplored industry. With no major changes in regulations regarding leverage and no immediately perceptible financial innovations the second category seems unlikely as well. This leaves fraud or morally questionable business practices, which have no reason to have increased in recent history. While I believe a correction would be a reasonable market action (especially if/when inflation starts to tick up), I’m not anticipating Great Recession 2.0 anytime soon.*** The most likely driver of inflated asset prices in the current environment is central bank activity (ZIRP, asset purchases, etc), the effects of which are far more widespread than just the stock market. Barring any dramatic changes on the horizon in other asset classes or inflation, the freely available information regarding the nature of policies, and central bankers penchant for deliberate and widely telegraphed actions, it’s hard to believe there will be a dramatic devaluation.


While we can all acknowledge that Beanie Babies aren’t worth much more than their sale price regardless of their rarity, to this day they still sell for thousands of dollars. Money laundering? Some other nefarious scheme? The world may never know. The point is that they still retain at least some value. At the end of bubbles, all assets return to a widely accepted fair value.




Disclosures (23 Jan 2018):

* I’m long Amazon stock.

** I don’t currently have any positions in cryptocurrencies.

*** I’m long stocks in general. This is my opinion and not investment advice obviously.

The Social Good of Bubbles – Part I

Did the bubble just pop? Where are we going (and who’s driving this bus)? The word “bubble” gets thrown around a lot but not a lot of people have a good, working definition of what exactly a bubble is. A sound investment thesis requires a rational framework for valuing the asset in question, a timeframe for the reconciliation of the difference between price and value if any, and a sound understanding of the economic ecosystem that produces different types of price action.

So let’s explore bubbles.

What is a bubble?

“An economic bubble or asset bubble… is trade in an asset at a price or price range that strongly exceeds the asset’s intrinsic value. It could also be described as a situation in which asset prices appear to be based on implausible or inconsistent views about the future.”

Wikipedia – Economic Bubble

“A speculative bubble [is] a situation in which news of price increases spurs investor enthusiasm, which spreads by psychological contagion from person to person, in the process amplifying stories that might justify the price increases, and bringing in a larger and larger class of investors who, despite doubts about the real value of an investment, are drawn to it partly by envy of others’ successes and partly through a gamblers’ excitement.”

– Robert Shiller, Irrational Exuberance

Combining these two definitions, we can think of a “bubble” as a period of time in markets when price significantly exceeds intrinsic value for reasons driven by cultural dynamics and/or emotions.

Price vs. Value: Going back to Finance 101, intrinsic value is the sum of the present value of all future cash flows. For securities like bonds, this is straightforward – take the present value of all of the coupons, add the present value of the principal to be paid back at maturity to get the expected current price of the bond. A similar calculation can be applied to dividend-paying stocks by calculating the present value of expected dividends, but one in six companies currently in the S&p 500 don’t actually pay a dividend (you didn’t think this was all about Bitcoin, did you?). These are companies like Google, Amazon, and Facebook (with market caps of $750B, $580B, and $530B respectively) so investors presumably think they’ll gain some sort of value in the future by owning shares.** There exists a grey area in estimating these future cash flows – this grey area is what creates a market. Some participants estimate that the price of the asset will go up, others estimate it will go down – otherwise no trading would occur. An even grayer area exists when the fundamental nature of the contract changes, as occurred in some of the bubbles listed below.

Psychology: Economics assumes that all market participants act in a way to maximize their individual utility. For better or for worse, reality is far messier. A discussion of the underlying reasons behind bubbles is outside of the scope of this article, but some interesting areas for further study include crowd psychology, mass hysteria, and the greater fool theory. As Peter M. Garber points out in Famous First Bubbles, “[p]sychological state of mind is not a measurable concept, especially years after an event. It does, however, provide a convenient way of explaining some phenomena in the market that cannot otherwise be explained” (p.4).

When the financial media talks about bubbles, they are usually using the term to imply an impending collapse in price as well. This can be a collapse in an individual entity, an industry, or an entire economy. More on this in the next post.

Famous Bubbles

Tulip Mania

Tulips, a luxury item, were traded in futures transactions conducted mainly at taverns. After speculators suffered losses in 1636, government officials change the contracts to benefit buyers. Some academics argue this was not a bubble.
Era/Economic Environment
Dutch Golden Age, Middle of the Thirty Years War
Peak Early 1637
Where Netherlands
Ground Zero Speculators
Widest scope
Wealthy merchants and craftsmen
Enabling Financial Condition(s)
The conversion of all futures contracts to options contracts in late 1636
Trigger (if any)
Buyers did not show to a routine auction
no critical influence on the prosperity of the Dutch Republic


South Sea Company

A scandalous, kleptocratic scheme devised by Tory leader Robert Harley to reduce British national debt.
Era/Economic Environment
“a time of prosperity and opulence”; end of the War of the Spanish Succession; heavy IPO issuance across Europe
Peak Aug 1720
Where Great Britain
Ground Zero Politicians
Widest scope
Unknown – presumably limited to speculators/investors who had access to London’s stock trading activities (mostly held at Jonathan’s Coffee-House at the time)
Enabling Financial Condition(s)
Rumor mongering, bribery, national pride, New World trade excitement, subscription share model of purchasing stock (leverage)
Trigger (if any)
SSC management selling shares, a decline in all stocks in London and internationally, first payment date for shares purchased on installment plans
Impeachment/imprisonment of some of the government officials and company officers involved; financial ruin for many speculators


Railway Mania

Economic expansion fuels speculative investments in both legitimate and illegitimate railroad endeavors.
Era/Economic Environment
Booming British economy with a literate middle class looking for investment opportunities after the Bubble Act (created after the South Sea Bubble) was repealed in 1825
Peak 1846
Where Great Britain
Ground Zero Industrialists
Widest scope Unknown
Enabling Financial Condition(s)
Lax regulatory environment (“laissez faire capitalism”), new investors seeking dividends (“dumb money”), subscription shares (leverage)
Trigger (if any)
Rapidly decaying economic environment (for more information look up the Irish Potato Famine)
“A giant and very speculative undertaking that succeeded”. Many households lost their investments/savings, but the UK gained over 6k miles (approx 10k km) of track.


Black Tuesday

Excessive (leveraged) speculation, now-criminal banking practices, and fraudulent investment schemes in a time of great economic prosperity leads to spectacular market crash and the Great Depression.
Era/Economic Environment
Roaring 20s – economic prosperity in the Western world
Peak Oct 1929
Where US
Ground Zero Stock Market
Widest scope World
Enabling Financial Condition(s)
Economic and technological booms
Trigger (if any)
Lackluster economic data, LSE crash triggered by the incarceration of key investors, unstable trading activity, margin calls on highly levered positions, tightening Fed policy, Hawley–Smoot Tariff Act
the Great Depression


Automobile Manufacturing

By 1930, according to wikipedia over 1,800 automobile companies had been created and subsequently disbanded in the United States alone. Not a bubble, per se, but an example of many investors chasing innovation and returns.
Era/Economic Environment
Early 20th Century
Peak Arguable
Where US
Ground Zero N/A
Widest scope N/A
Enabling Financial Condition(s)
See Black Tuesday
Trigger (if any)
Great Depression
Industry consolidation leaving “the Big Three” major companies in the US


Beanie Babies

Stuffed bears retailing for $20 were valued at hundreds of thousands of dollars in the 90s.
Era/Economic Environment
90s Economic Boom
Peak 1999
Where US
Ground Zero
Teachers and Housewives in Chicago
Widest scope Unknown
Enabling Financial Condition(s)
Ebay – the emergence of P2P commerce
Trigger (if any)
Prices did not increase as expected after a routine retirement announcement
No widespread economic impact; the current value of the stuffed animals is unclear. Recent eBay auctions show “Princess Bears” still selling for as much as $15k. Presumably these are fraudulent transactions or naive buyers.


Tech Bubble / Dot-Com Boom

Description Excited about the internet, investors piled cash into anything claiming to be even remotely related to technology.
Era/Economic Environment 90s Economic Boom
Peak 2001/2002
Where US
Ground Zero Silicon Valley
Widest scope Investors worldwide
Enabling Financial Condition(s) The internet

Result/Aftermath Trillions of dollars lost, “nearly 5,000 Internet companies [were] either… acquired or shut down in a massive sector consolidation.”


Housing Bubble (US) / Subprime Mortgage Crisis

Description Mistrusting stocks after the tech bubble, investors pile into real investments. Securitization and lax lending standards fueled the fire.
Era/Economic Environment Strong economic growth
Peak 2007
Where US (similar bubbles happened worldwide)
Ground Zero Housing Market
Widest scope Anyone with a real estate investment
Enabling Financial Condition(s) ABS/MBS
Trigger (if any) Weak economic growth, unservicable debts (e. g. option ARMs)
Result/Aftermath The Great Recession

2017 in Review

Happy New Year, hope you had a good holiday.

A few questions for 2018:

  • Will equities continue to rally?
  • Similarly, will the yield curve invert and herald the next recession?
  • Whatever happened to inflation?
  • What forces will dominate oil prices in the upcoming year – Saudia Arabia/OPEC, shale production, alternative energy, or something else?
  • What effect will tax reforms really have on the market?
  • What will end the credit rally?
  • Bitcoin?
  • More broadly, which cryptocurrency will become dominant?
