It started in August 2020 with GameStop. Then AMC and Blackberry Limited. And now Tupperware, Yellow, and Rite Aid are the latest companies to be turned into meme stocks. While meme stocks can see their prices increase over 1,000% (GameStop) and some meme stock companies have seen their stock prices remain higher over time, the volatility in meme stocks is incredibly high and many of the companies that become meme stocks have seen their stock go even lower after a meme stock rally (or have been delisted like Bed,Bath & Beyond), leaving retail investors with nothing. Ultimately, meme stocks are incredibly risky because they are at the whims of investors’ emotions rather than true predictors of value (i.e., earnings, new product development).
As a Financial Professional (FP), it is important to understand a client’s motivations if they want to pursue a meme stock (or meme stock ETF) and how these align with their plans and goals. Even clients who aren’t interested in investing in meme stocks may use meme stock rallies to predict the stock market’s near- and medium-term performance. This too can be misleading as investor sentiment and market realities can be terribly misaligned. Understanding why meme stock rallies occur and how they can affect the overall market can help FPs guide their clients through market volatility—including upswings that may be unrelated to fundamental economic indicators.
Trying to define or explain a meme can be a surprisingly difficult task. Memes, at their core, are representations of the current zeitgeist—trends, products, people, and ideas can all become memes. Ultimately, there are two key characteristics that underlie memes—they are driven by social media, and they require some level of virality. Meme stocks, specifically, are the combination of memes and the stock market—they are stocks that have become popular (gone viral) because of social media. The companies that gain meme status are usually failing and/or have low stock values. Another important component of meme stocks and something that falls squarely on the investment side of the social media-stock market overlap: the stock usually has a high level of short interest (shares that have been sold short and have not been covered/repurchased). Short interest can increase in a stock because investors expect the price of the stock to decrease—this is how they make money on the (short) sale of shares they have borrowed.
In short selling, the seller only makes money if the stock price is lower than what they originally borrowed shares at and shares must be “returned” to the lender by an agreed upon date. This means that if stock prices increase above what the stock was borrowed at, the short seller loses money (the difference between the higher price and the borrowed price). When there is a large amount of short interest (usually anything above 10% of a company’s shares), there can be a short squeeze—this is when short sellers try to buy shares as quickly as possible to cover their positions and avoid further losses.
Meme stocks are a relatively new phenomenon—the first meme stock was born in August 2020 when Reddit users decided to start rallying behind GameStop. At its peak, GameStop’s short interest was just under 142%1—that means the same shares were being shorted multiple times. This level of short interest can destabilize stock markets in the face of a short squeeze as losses snowball and short sellers panic and cover their positions, which only further increases the stock’s price, exacerbating losses and the associated panic. The short squeeze on GameStop’s stock resulted in the loss of billions of dollars for institutional investors and forced one hedge fund out of business.2
The stock market rally behind the GameStop short squeeze was initiated and encouraged by users on the social media site, Reddit. The push for the rally was emotional—some cited nostalgia for the company while others got involved because they wanted to punish institutional investors. As the price increased, more investors jumped on the bandwagon, driving the price up further. In other words, the sudden and continued increase in prices for GameStop shares was not driven by any news or recent developments around the company, it was driven by emotions.
Meme stocks are fascinating because they should rarely happen. According to the efficient market hypothesis, asset prices reflect all available information—this means that if a stock is expected to rise in value, this is reflected in its price. Another way to think of this is, if a stock is undervalued, investors can purchase it with the plan of making a return when the price goes up—but this very act of purchase drives the price up, bringing the asset to its true value. While there are market anomalies that go against the efficient market hypothesis, these are usually corrected quickly, making it very hard for any retail or institutional investors to consistently beat the market over time.
In 2022, meme investing took a downturn with the rest of the market. The meme ETF3 (ticker: MEME), started in December 2021 by Roundhill Investments, dropped from $70 per share to $25.4 Further, many of the meme stocks that had dramatic price increases in 2021, saw prices drop sharply, with some ending below where they were before meme investors started a rally. Even those that did maintain a higher price level did so at prices significantly lower than what they peaked at. Many analysts thought that meme stocks had run their course and were a trend unlikely to be continued. And that did seem to be the case through 2022, but recently there has been a resurgence. The meme ETF has gone back up and even outperformed the S&P 500.5 And a new crop of fan-favorite stocks has appeared, including Tupperware,Yellow, and Rite Aid.6 Shares for these companies have risen as much as 800% in the past few weeks, despite all three of them having given indications of failing.7
This resurgence has led some analysts and hedge fund managers to declare the landscape of the stock market permanently altered8—suggesting that short-selling has become even more risky as retail investors can cause billions of dollars in losses just because. This means that analysis and research can suggest a reasonable course of action, such as short selling because of an expectation share price will decrease (e.g., Yellow signaled it planned to declare bankruptcy), and that action can result in major losses because of chatter on social media platforms. Even just the threat that meme investing could resurge after a lull adds a dimension of risk that will make many institutional investors uncomfortable with short-selling specific stocks.

Roundhill Investments introduced the meme stock ETF, MEME, in December 2021. The ETF is a portfolio of 25 stocks, where securities are included based on a “meme score.” This score is calculated as the number of times a firm is mentioned on pre-specified social media sites over a 14-day period and with additional weight given to a company’s short interest. The portfolio is rebalanced twice a month. For more information, see: https://www.roundhillinvestments.com/etf/meme/
