As of June 17, 2024, the most shorted stock was for, the American holographic technology services provider, MicroCloud Hologram Inc., with 66.64 percent of their total float having been shorted. This is a change from mid-January 2021, when video game retailed GameStop had an incredible 121.07 percent of their available shares in a short position. In effect this means that investors had 'borrowed' more shares (with a future promise to return them) than the total number of shares available for public trading. Owing to this behavior of professional investors, retail investors enacted a campaign to drive up the stock price of Gamestop, leading to losses of billions when investors had to repurchase the stock they had borrowed. At this time, a similar – but less effective – social media campaign was also carried out for the stock price of cinema operator AMC, and the price of silver. What is short selling? Short selling is essentially where an investor bets on a share price falling by: borrowing a number of shares selling these shares while the price is still high; purchasing the same number again once the price falls; then returning the borrowed shares at a profit. Of course, a profit will only be made if the share price does fall; should the share price rise the investor will then need to purchase the shares back at a higher price, and thus incur a loss. Short selling can lead to some very large profits in a short amount of time, with Tesla stock generating over one billion dollars in short sell profits during the first week of March 2020 alone, owing to the financial crash caused by the coronavirus (COVID-19) pandemic. However, owing to the short-term, opportunistic nature of short selling, these returns look less impressive when considered as net profits from short sell positions over the full year. The risks of short selling Short selling carries greater risks than traditional investments, and for this reason financial advisors often recommend against this strategy for ‘retail’ (i.e. non-professional) investors. The reason for this is that losses from short selling are potentially uncapped, whereas losses from traditional investments are limited to the initial cost. For example, if someone purchases 100 dollars of shares, the maximum they can lose is the 100 dollars the spent on those shares. However, say someone borrows 100 dollars of shares instead, betting on the price falling. If these shares are then sold for 100 dollars but the price subsequently rises, the losses could greatly exceed the initial investment should the price rise to, say, 500 dollars. The risks of short selling can be seen by looking again at Tesla, with the company causing the greatest losses over 2020 from short selling at over 40 billion U.S. dollars.

Over the course of 2020, U.S. short sellers generated a net profits of around 1.28 billion U.S. dollars from short selling Exxon Mobil stock. While a very large number, this pales in comparison to the net annual losses of from short selling of over 40 billion U.S. dollars for Tesla stock. Short selling is a process whereby investors effectively borrow a certain number of shares for a period of time, with the aim of selling them when the price is high, then repurchasing at a lower price in order to return them.

In 2024, ** percent of adults in the United States invested in the stock market. This figure has remained steady over the last few years, and is still below the levels before the Great Recession, when it peaked in 2007 at ** percent. What is the stock market? The stock market can be defined as a group of stock exchanges, where investors can buy shares in a publicly traded company. In more recent years, it is estimated an increasing number of Americans are using neobrokers, making stock trading more accessible to investors. Other investments A significant number of people think stocks and bonds are the safest investments, while others point to real estate, gold, bonds, or a savings account. Since witnessing the significant one-day losses in the stock market during the Financial Crisis, many investors were turning towards these alternatives in hopes for more stability, particularly for investments with longer maturities. This could explain the decrease in this statistic since 2007. Nevertheless, some speculators enjoy chasing the short-run fluctuations, and others see value in choosing particular stocks.

The smooth functioning of the stock lending market is essential for enabling short selling and maintaining effective arbitrage. Yet, little is known about how this low-transparency market responds to acute disruptions such as short squeezes. Short selling plays a central role in price efficiency, without which prices would disproportionately reflect the beliefs of the optimist. Cheap access to shares from lending institutions facilitates this process. The January 2021 short squeeze – centered around GameStop but involving a wider array of highly shorted equities – created extreme market conditions. While regulatory and academic attention has largely been focused on the squeeze’s effect on price volatility and more visible metrics of market quality, the squeeze’s effects on the stock lending market have not been thoroughly explored. Through an OLS regression framework, this paper analyzes how borrowing costs behaved across the highly shorted segment of the market, as compared to the non-shorted, broader market segment. The results show that during the squeeze, borrow fees increased, but only in the highly shorted group. In the post-squeeze period, borrow fees fell significantly, but again only within the highly shorted group. The stability of control group metrics supports the idea that the observed effects were concentrated solely within highly shorted equities. These results contribute to the literature on short sale constraints, bringing further implications for inefficiencies beyond what the existing literature had shown. Furthermore, this paper provides evidence that the lending market distortions brought on by a short squeeze may persist beyond the event window, interfering with effective arbitrage.

Consistent growth in assets under management (AUM) has immensely benefited the Hedge Funds industry over the past five years. Industry servicers invest capital they receive from a variety of investor types across a broad range of asset classes and investment strategies. Operators collect a fee for the amount of money they manage for these clients and a percentage of gains they are able to generate on invested assets. This business model helped industry revenue climb at a CAGR of 7.7% to $127.4 billion over the past five years, including an expected incline of 5.7% in 2024. Despite economic volatility in 2020 due to the pandemic lowering interest rates, an incline in the value of stocks in 2020 positively affected many hedge funds. The S&P 500 climbed 16.3% in 2020, which helped increase AUM. Although industry professionals question the relevance of benchmarking hedge fund returns against equity performance, given that hedge funds rely on a range of instruments other than stocks, the industry's poor performance relative to the S&P 500 has begun to raise concern from some investors. These trends have affected the industry's structure, with the traditional 2.0 and 20.0 structure of a flat fee on total AUM and a right-to-earned profit deteriorating into a 1.4 and 16.0 arrangement. As a result, industry profit, measured as earnings before interest and taxes, has been hindered over the past five years. Industry revenue is expected to grow at a CAGR of 3.1% to $148.5 billion over the next five years. AUM is forecast to continue increasing at a consistent rate, partly due to the diversification benefits that hedge funds provide. Nonetheless, increased regulation stemming from the global financial crisis and an escalating focus on the industry's tax structure has the potential to harm industry profit. Further economic uncertainty stemming from heightened inflation and persistently high interest rates is anticipated to dampen any large-scale growth for the industry as more hedge funds take a hawkish approach in their investment portfolio moving forward. Regardless, the number of new hedge funds is forecast to trend with AUM and revenue over the next five years.
