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.

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.

Workers’ compensation and other insurance funds businesses have experienced significant changes in recent years, largely driven by economic fluctuations and shifts in investment income. The crash of the US economy in 2020 due to pandemic-related restrictions placed immense pressure on the industry. Business formation plunged and unemployment soared, resulting in a diminished customer base for insurance funds and a steep drop in revenue. Regardless, the Federal Reserve's injection of liquidity into the financial system propelled stock prices upward, boosting investment income for insurance providers. This increase in investment income provided some relief for providers, enabling them to cover expenses and sustain profits despite revenue losses. The relaxation of COVID-19 restrictions spurred economic recovery in 2021, driving unemployment down and corporate profit up. This positive economic climate increased demand for insurance services and enhanced investment income due to robust stock market conditions. However, since 2022, inflation has wreaked havoc, causing businesses and organizations to slash investments in insurance funds amid soaring prices. More recently, rising interest rates have reduced downstream demand due to the emergence of recessionary fears, but revenue and profit have expanded because of growing returns on fixed-income products. Overall, revenue for workers’ compensation and other insurance funds has inched downward at a CAGR of 0.2% over the past five years, reaching $56.6 billion in 2025. This includes a 0.5% rise in revenue in that year. Looking ahead, providers are poised for moderate growth over the next five years. As the US economy stabilizes, with solid GDP growth and potential increases in business formation and employment, the customer base for insurance funds is likely to expand. These favorable economic conditions should bolster consumer confidence and investment in the stock market, leading to greater investment income for the industry. Nonetheless, larger players are expected to dominate, given their ability to invest in cutting-edge technologies like AI for predicting claim risks and optimizing business operations. Smaller providers may face intensified internal competition, prompting some to exit the market, while others could focus on niche offerings or invest in technological advancements to remain viable and competitive. Overall, revenue for workers’ compensation and other insurance funds is expected to expand at a CAGR of 1.3% over the next five years, reaching $60.3 billion in 2030.

The total global net assets of mutual funds registered in the United States amounted to approximately 25.5 trillion U.S. dollars in 2023, compared to around 5.53 trillion U.S. dollars in 1998. Mutual funds - additional information Mutual funds are investment funds in which the capital is pooled from a number of different investors and then used to buy securities such as stocks, bonds or money market instruments. Although investing in mutual funds, rather than direct investment in individual securities, still presents a certain degree of risk, it has become more and more common practice around the world. One of the biggest advantages of this type of investment is the fact that the fund assets are managed by professionals, who aim to eliminate some of the risk involved in investing in individual stocks and bonds through diversification of assets. As of 2022, there were almost 7,400 mutual funds domiciled in the United States. There are four main types of mutual funds, categorized by the nature of their principal investments, namely: stock or equity funds (whether domestic or international), bond or fixed income funds, money market funds and hybrid funds. In 2022, domestic equity funds were the most popular category in the United States, representing 46 percent of all mutual fund and ETF assets.

Trading conditions have been challenging for fund managers, as fierce competition has resulted in cost-cutting initiatives. In particular, actively managed funds have suffered from a substantial reduction in management fees. The ongoing price war in passive investment in the exchange traded funds (ETFs) market has exerted additional downwards pressure on margins. The COVID-19 pandemic, geopolitical tensions, inflationary pressures and elevated interest rates led to significant uncertainty and volatility in financial markets. This has negatively influenced the valuation of some securities, resulting in slumps in AUM and higher withdrawal requests. Overall, fund management services revenue is expected to weaken at an annualised 1.9% over the five years through 2024-25 to total $12.1 billion. This includes an anticipated hike of 4.7% in 2024-25, The rise of environmental, social and governance (ESG) and thematic investing has strongly influenced funds management revenue in recent years. Investors are increasingly looking to invest in funds that align with their social and sustainability goals, prompting fund managers to launch new funds and offer methods like custom indexing to meet demand. This trend has opened the door for fund management companies to carve out market niches. Products like ESG funds and custom indexing also come with higher management fees, offsetting margin declines from mounting competitive pressures. Profit margins are on track to climb thanks to increased investment in ESG that will support growth in funds management services. Fund management companies are set to allocate more resources to ensure compliance with sustainability claims amid the growing regulatory crackdown on greenwashing. The launch of the first-ever set of global sustainability reporting standards in 2024 standardised ESG-related disclosures and enhanced the credibility of sustainable funds. Emerging technologies like tokenisation and quantum computing, combined with the potential managed investment scheme reform in Australia, will revolutionise funds management in the coming years. These new forces and trends are why fund management revenue is forecast to expand at an annualised 2.9% through the end of 2029-30, to $14.0 billion.

They play an important role in household finances in the United States of today, most notably in retirement planning.

The nature of the fund as a collective investment vehicle provides increased diversification and ease of comparison to investors. The fact that they are managed professionally, and that the investment is pooled, enables participation in investments that would normally only be available to larger investors.

Fees are an inevitable part of a professionally managed fund, as is the inability to customize the investment. A common complains is also that the investor has less control over timing of the recognition of their gains.

When weighted components rise in value, this causes an increase in the overall value of the index they are weighted too. What trends are driving index performance?
