The Rise of Hedge Funds: Exploring Their Impact on Financial Markets


Hedge funds are significant players in financial markets given the size of their capital bases and the frequency of their trading. According to a report by Hedge Fund Research, Inc., as of the end of 2020, hedge funds managed approximately $3.6 trillion in assets globally. There have been various estimates of the percentage of equity volume that is controlled by hedge funds. One widely cited estimate is that hedge funds account for around 5-6% of total equity trading volume in the US. However, this figure can vary widely depending on the specific market, the time period being considered, and the methodology used to estimate hedge fund ownership. It’s important to note that hedge fund activity in financial markets can have a significant impact on stock prices and market volatility, even if hedge funds do not control the majority of the volume. Some of these impacts include market liquidity, risk and efficiency, and can be both positive and negative for financial markets.


Market Liquidity 

Hedge funds are large and active players in nearly every financial market, including equities, publicly traded credit, options, futures, commodities, etc. Simply put, given that they are such large players in various markets, it helps increase liquidity in these markets. Additionally, they are typically more active in trading than other types of investment firms, increasing opportunities for market participants to buy and sell financial products.

Contrary to what critics may think, short selling can be a positive for market liquidity. Short selling involves borrowing shares and selling them with the intention of buying them back at a lower price. Short selling can increase liquidity by increasing the supply of shares available for trading.

Additionally, some hedge funds act as market-makers, providing bids and offers for securities to other market participants. This can help to ensure that there is always a buyer or seller available, which can increase market liquidity. Citadel Securities is one of the leading market-makers in the world.

Liquidity is a very important feature of well-functioning financial markets. Liquidity is essential for businesses and governments to access capital. When markets are liquid, they can issue securities to raise capital quickly and efficiently. This helps to ensure that businesses can access the funding they need to grow and invest in new projects. Additionally, liquidity is important for governments because it gives them access to debt markets to sell securities to fund deficits. Further, liquidity is important to help funds of all types manage risk and improve market stability.


Price Volatility 

Hedge funds often take large positions in specific securities, which can lead to increased price volatility. Hedge funds can take concentrated positions. Additionally, many hedge funds may take the same or similar positions, resulting in a higher concentration than may be understood. When certain positive or negative market events occur, concentration can result in high price volatility as hedge funds try to get out of a concentrated position. A great example of price volatility is the GameStop short squeeze.

Hedge funds also engage in algorithmic trading. Hedge funds often use sophisticated algorithms to execute their trades. These algorithms can react quickly to changes in market conditions, which can contribute to sudden price movements. Further, hedge funds often engage in speculative trading, which involves buying and selling securities based on expected future price movements. This can contribute to price volatility as other market participants may react to the hedge fund’s speculative positions. 

Different types of price volatility can be both positive and negative, as they create trading opportunities for other investors or cause market disruptions.


Market Efficiency 

Market efficiency is all about the ability of a security to realize its intrinsic value. Hedge funds’ goal is to efficiently and as correctly as possible figure out the intrinsic value of a security and realize that price. Hedge funds often have access to a wide range of information and resources to help them do just that. They can identify mispricings in the market, which can help correct pricing inefficiencies and improve market efficiency.

Additionally, hedge funds are often involved in arbitrage strategies, which involve taking advantage of pricing discrepancies between different markets or securities. By buying undervalued securities and selling overvalued ones, hedge funds can help correct pricing inefficiencies.

Hedge funds are also often activist investors, which means that they take an active role in managing the companies in which they invest. By engaging with company management and advocating for changes that improve efficiency and profitability, hedge funds can help improve market efficiency.


Risk Management 

While some individual hedge funds can be negative for financial risk, on the whole, hedge funds that engage in proper risk management help reduce overall market and system risk in financial markets. Hedge funds often use a variety of investment strategies and invest across multiple asset classes, which can help diversify their portfolio and reduce risk. This diversification can also help reduce systemic risk in the market by spreading risk across a wide range of assets.

Hedge funds often employ risk management strategies, which can help identify and mitigate potential risks. These strategies can include stress testing, scenario analysis, and risk monitoring, among others. Risk management helps hedge funds preserve their investors’ capital, helping reduce risk in other parts of the economy. Since some of the largest investors in hedge funds are pension funds, risk management helps pension funds stay afloat in bad markets, reducing systemic risk in financial markets.

One tool for risk management is hedging. As the name suggests, hedge funds often use hedging strategies to manage risk. Hedging involves taking positions in securities or derivatives that are negatively correlated with the assets in their portfolio. This can help offset potential losses and reduce risk by keeping their investors’ money safe from negative market events.


Market Manipulation 

On the negative side, bad actors at hedge funds can engage in market manipulation. Market manipulation refers to the deliberate attempt to influence the price or value of a security or asset to benefit oneself or one’s clients. There have been many high-profile attempts and accusations of market manipulation by hedge funds. It’s important to note that not all hedge funds engage in market manipulation. Hedge funds, like any other market participant, are subject to regulatory oversight and can be held accountable for illegal behavior.
