The GameStop affair is like tulip mania on steroids

It’s eerily similar to the 17th-century Dutch bubble, but with the self-organising potential of the internet added to the mix writes Dan Davies in The Guardian

  

Towards the end of 1636, there was an outbreak of bubonic plague in the Netherlands. The concept of a lockdown was not really established at the time, but merchant trade slowed to a trickle. Idle young men in the town of Haarlem gathered in taverns, and looked for amusement in one of the few commodities still trading – contracts for the delivery of flower bulbs the following spring. What ensued is often regarded as the first financial bubble in recorded history – the “tulip mania”.

Nearly 400 years later, something similar has happened in the US stock market. This week, the share price of a company called GameStop – an unexceptional retailer that appears to have been surprised and confused by the whole episode – became the battleground between some of the biggest names in finance and a few hundred bored (mostly) bros exchanging messages on the WallStreetBets forum, part of the sprawling discussion site Reddit. 

The rubble is still bouncing in this particular episode, but the broad shape of what’s happened is not unfamiliar. Reasoning that a business model based on selling video game DVDs through shopping malls might not have very bright prospects, several of New York’s finest hedge funds bet against GameStop’s share price. The Reddit crowd appears to have decided that this was unfair and that they should fight back on behalf of gamers. They took the opposite side of the trade and pushed the price up, using derivatives and brokerage credit in surprisingly sophisticated ways to maximise their firepower.

To everyone’s surprise, the crowd won; the hedge funds’ risk management processes kicked in, and they were forced to buy back their negative positions, pushing the price even higher. But the stock exchanges have always frowned on this sort of concerted action, and on the use of leverage to manipulate the market. The sheer volume of orders had also grown well beyond the capacity of the small, fee-free brokerages favoured by the WallStreetBets crowd. Credit lines were pulled, accounts were frozen and the retail crowd were forced to sell; yesterday the price gave back a large proportion of its gains.

To people who know a lot about stock exchange regulation and securities settlement, this outcome was quite inevitable – it’s part of the reason why things like this don’t happen every day. To a lot of American Redditors, though, it was a surprising introduction to the complexity of financial markets, taking place in circumstances almost perfectly designed to convince them that the system is rigged for the benefit of big money.

Corners, bear raids and squeezes, in the industry jargon, have been around for as long as stock markets – in fact, as British hedge fund legend Paul Marshall points out in his book Ten and a Half Lessons From Experience something very similar happened last year at the start of the coronavirus lockdown, centred on a suddenly unemployed sports bookmaker called Dave Portnoy. But the GameStop affair exhibits some surprising new features.

Most importantly, it was a largely self-organising phenomenon. For most of stock market history, orchestrating a pool of people to manipulate markets has been something only the most skilful could achieve. Some of the finest buildings in New York were erected on the proceeds of this rare talent, before it was made illegal. The idea that such a pool could coalesce so quickly and without any obvious sign of a single controlling mind is brand new and ought to worry us a bit. 

And although some of the claims made by contributors to WallStreetBets that they represent the masses aren’t very convincing – although small by hedge fund standards, many of them appear to have five-figure sums to invest – it’s unfamiliar to say the least to see a pool motivated by rage or other emotions as opposed to the straightforward desire to make money. Just as air traffic regulation is based on the assumption that the planes are trying not to crash into one another, financial regulation is based on the assumption that people are trying to make money for themselves, not to destroy it for other people.

When I think about market regulation, I’m always reminded of a saying of Édouard Herriot, the former mayor of Lyon. He said that local government was like an andouillette sausage; it had to stink a little bit of shit, but not too much. Financial markets aren’t video games, they aren’t democratic and small investors aren’t the backbone of capitalism. They’re nasty places with extremely complicated rules, which only work to the extent that the people involved in them trust one another. Speculation is genuinely necessary on a stock market – without it, you could be waiting days for someone to take up your offer when you wanted to buy or sell shares. But it’s a necessary evil, and it needs to be limited. It’s a shame that the Redditors found this out the hard way.

The lesson for diagnosing a bubble

Tim Harford in The Financial Times

Here are three noteworthy pronouncements about bubbles. 

“Prices have reached what looks like a permanently high plateau.” That was Professor Irving Fisher in 1929, prominently reported barely a week before the most brutal stock market crash of the 20th century. He was a rich man, and the greatest economist of the age. The great crash destroyed both his finances and his reputation. 

“Those who sound the alarm of an approaching . . . crisis have somewhat exaggerated the danger.” That was a renowned commentator who shall remain nameless for now. 

“We are currently showing signs of entering the blow-off or melt-up phase of this very long bull market.” That was investor Jeremy Grantham on January 3 this year. The normally bearish Mr Grantham mused that while shares seem expensive, historical precedents make it plausible that the S&P 500 will soar from present levels of around 2,700 to more than 3,500 before the crash occurs. 

Mr Grantham’s speculation is striking because he has tended to be a savvy bubble watcher in the past. But as any toddler can attest, it is not an easy thing to catch one before it bursts. 

There are two obvious ways to diagnose a bubble. One is to look at the fundamentals: if the price of an asset is unmoored from the cash flow it is likely to generate, that is a warning sign. (It is anyone’s guess what this implies for bitcoin, an asset that has no cash flow at all.) 

The other approach is to look around: are people giddy with excitement? Can the media talk of little else? Are taxi drivers offering stock tips? 

At the moment, however, these two approaches tell a different story about US stocks. They are expensive by most reasonable measures. But there are few other signs of speculative mania. The price rise has been steady, broad-based and was hardly the leading news of 2017. Given how expensive bonds are, it is hardly a surprise that stocks also seem pricey. No wonder investors and commentators are unsure what to say or do. 

It seems all so much easier with hindsight: looking back, we can all enjoy a laugh at the Extraordinary Popular Delusions and the Madness of Crowds, to borrow the title of Charles Mackay’s famous 1841 book, which chuckles at the South Sea bubble and tulip mania. 

Yet even with hindsight things are not always clear. For example, I first became aware of the incipient dotcom bubble in the late 1990s, when a senior colleague told me that the upstart online bookseller Amazon.com was valued at more than every bookseller on the planet. A clearer instance of mania could scarcely be imagined. 

But Amazon is worth much more today than at the height of the bubble, and comparing it with any number of booksellers now seems quaint. The dotcom bubble was mad and my colleague correctly diagnosed the lunacy, but he should still have bought and held Amazon stock. 

Tales of the great tulip mania in 17th-century Holland seem clearer — most notoriously, the Semper Augustus bulb that sold for the price of an Amsterdam mansion. 

“The population, even to its lowest dregs, embarked in the tulip trade,” sneered Mackay more than 200 years later. 

But the tale grows murkier still. The economist Peter Garber, author of Famous First Bubbles, points out that a rare tulip bulb could serve as the breeding stock for generations of valuable flowers; as its descendants became numerous, one would expect the price of individual bulbs to fall. 

Some of the most spectacular prices seem to have been empty tavern wagers by almost-penniless braggarts, ignored by serious traders but much noticed by moralists. The idea that Holland was economically convulsed is hard to support: the historian Anne Goldgar, author of Tulipmania, has been unable to find anyone who actually went bankrupt as a result. 

It is easy to laugh at the follies of the past, especially if they have been exaggerated for the purposes of sermonising or for comic effect. Charles Mackay copied and exaggerated the juiciest reports he could find in order to get his point across. Then there is the matter of his own record as a financial guru. That comment, this time in full, “those who sound the alarm of an approaching railway crisis have somewhat exaggerated the danger”, was Mackay himself, writing in the Glasgow Argus in 1845, in full-throated support of the idea that the railway investment boom of the time would return a healthy profit to investors. It was, instead, a financial disaster. In the words of mathematician and bubble scholar Andrew Odlyzko, it was “by many measures the greatest technology mania in history, and its collapse was one of the greatest financial crashes”. 

Oddly, Mackay barely mentions the railway mania in subsequent editions of his book — nor his own role as cheerleader. This is a lesson to us all. It’s very easy to scoff at past bubbles; it is not so easy to know how to react when one may — or may not — be surrounded by one.
