Second, there is a lot of nonsense in the commentary. Many observers impart a moralizing tone. Some castigate hedge fund shorting, while others laud the “democracy” of finance. Both judgments are wrong.

For instance, why are value investors who buy cheap stocks heroes, but those who sell expensive stocks pariahs? In both cases, their actions nudge stocks toward their fundamental equilibrium. Surely both are good financially and economically.

As for economic or financial democracy, well, they are oxymorons. Democracy rests on the principle of one adult, one vote, whereas capitalism is based on the principle of one dollar, one vote. Capitalism and democracy sit uneasily alongside one another, but market-based systems of resource allocation should never be confused with, nor aspire to be, “democratic.” Allocating resources democratically is inimical to market economies, in extremis it is communist.

Third, a common misperception of the GameStop phenomenon is conveyed, unsurprisingly, by the name of the key trading platform involved, Robinhood. The implicit reference is that of a mechanism to steal from the rich and give to the poor. Yet the myth of Robin Hood, the legendary figure, is not the underlying principle of the Robinhood user. Initiating a short squeeze is probably not theft (we’ll return to that point shortly) and for certain no altruism is involved.

Rather, greed, and vengeance are more apt descriptions for much of what is going on. And, to borrow from Gordon Gekko, “greed is good,” at least when it comes to economic decision-making. More politely, economists refer to it as “self-interest,” but that is a semantic distinction without a difference. And, if the chat boards are anything to go by, some GameStop buyers were motivated by vengeance, a desire to extract pain from Wall Street.

Fourth, there is nothing wrong with hedge funds (or anyone else) being squeezed out of their shorts. It is a regular occurrence and rarely draws much attention. But market manipulation is another matter. To the extent that the actions of GameStop stock buyers were organized and coordinated, they could have crossed the line into illegal market manipulation. Indeed, the U.S. Securities and Exchange Commission defines market manipulation as an action that “artificially affects the supply or demand for a security (for example, causing stock prices to rise or to fall dramatically).”

Legally, there is much to unpack. Almost certainly lawyers and regulators will scrutinize what has just happened for any wrongdoing. Manipulating markets is a crime irrespective of whether the manipulators are buying or selling.

It is, however, also perfectly acceptable to convey legitimate market information—as opposed to rumor or falsehoods—to others, including on social media platforms. Reddit users did nothing wrong in alerting others that large short positions existed in GameStop and other securities. No one may dispute the legitimate use of any medium, such as Reddit, to convey factual information on which others may act in financial markets.

Fifth, there is considerable hypocrisy from various commentators about the ethics of short-selling. Those who take pleasure in the short squeeze of hedge funds apparently have forgotten how the media heralded The Big Short as the voice of sanity and virtue during the global financial crisis. How quickly attitudes toward shorting have changed.

Sixth, the GameStop episode has revealed how the financial services brokerage industry has changed. Information today flows freely and instantaneously to any willing participant in markets. Valuable information is no longer the privilege of the professionals. Low- or no-commission trading on platforms like Robinhood creates vast new opportunities for market participation. Some users may have been tantalized by moral tales of financial pitchforks skewering the lords of finance, but vengeance is unlikely to be the sole or even primary motivation for most of those now gaining direct access to the world of finance.

But with access comes responsibility, if not to others then to one’s own personal finances. There is precious little evidence that trading, per se, creates opportunities for sustainable wealth enhancement. Free market access to the uninitiated is akin to handing over the car keys to those with no experience behind the wheel. Accidents happen in finance as much as anywhere else.

If no other lessons are drawn from this experience, the financial services industry and its regulators should promote and offer early and continuing personal finance education. Savings, investment, and diversification are sound ways to manage personal finances, but acquiring those skills and knowledge ought to precede, not follow, access to the instruments of finance.

The GameStop episode also risks creating the false belief that trading is a legitimate way to make money. That is unlikely. For every story of a GameStop windfall there are many untold ones of losses. Short-term trading not only poses risks to the health of one’s financial portfolio. It may be addictive as well, an observation we make based on experience of family and friends.

Finally, the events of the last week exposed Robinhood investors to a risk they had not known, one that lurked out of sight, deep in the plumbing of the financial system. Specifically, as the price volatility of a security jumps, the clearing houses that facilitate the transfer of cash for stocks require more collateral from the broker to cover their risk of settling both sides of the trade.

In the case of GameStop and other stocks that were caught up in last week’s frenzy, the required excess collateral for Robinhood put at risk its financial standing. Robinhood was therefore forced to restrict trading in those stocks, exposing an army of retail buyers to significant losses.

In short, GameStop buyers may have felt they ran only price risk, when in fact they also faced illiquidity risk. Yet the revelation that markets, even for stocks, can become illiquid may ultimately send a powerful and welcome message—one of prudence and “buyer beware” that tempers future excesses. The plumbing of finance may not be glamorous, but it exists to facilitate market functioning. It may also play a beneficial role as a “sand in the wheels” mechanism, reminding traders of the risks inherent in wild stock rides.

GameStop offers useful lessons. But they are not about altruism. Nor are they about oxymoronic notions of financial democracy. GameStop was mostly about the usual suspects—greed and excessive positioning. Few lessons may be better than “buyer and seller beware.” Trading is risky business. Awareness requires knowledge. With greater access to markets, the industry and its watchdogs ought to redouble the access for all to sound financial education.

With greater knowledge, the game may not stop, but it might turn out better.
