# Arbitrageurs are investors who try to profit from market inefficiencies.
Many arbitrageurs take advantage of inconsistent prices for the same asset in different markets by simultaneously buying the asset at a lower price and selling the same asset at a higher price in different markets. Risk arbitrageurs, on the other hand, try to profit from price differences during mergers and acquisitions before the deal closes.
There is often confusion in this area of finance. For example, many people may know that arbitrageurs seek price differences between stocks by buying undervalued shares on one exchange while shorting the same amount of overvalued shares on another exchange. This leads people to think they can capture so-called "risk-free" profits because prices on both exchanges will converge. But this financial activity is fraught with risk.
Therefore, it is worth emphasizing that although this is true for certain trading situations, arbitrageur trading is by no means risk-free. Many arbitrageurs focus on merger arbitrage, which is fraught with various risks.
Another basic misconception relates to the practice that was once illegal for a long time and that arbitrageurs could face legal risks if they participated - not just hefty fines, but possibly even jail time. Historically, in risk or merger arbitrage, arbitrageurs often obtain inside information in order to stay ahead of others before a merger is announced. They may have contacts with law firms, investment banks, and accounting firms, or make calls to major companies that may be expanding. The purpose is to obtain critical information (usually for a fee) that allows arbitrageurs to trade ahead of any public announcements.
In the 1980s, several insider trading cases, including that of arbitrageur Ivan Boesky, led to the passage of the Insider Trading and Securities Fraud Enforcement Act of 1988, which increased penalties and required the U.S. Securities and Exchange Commission (SEC) to strengthen insider trading enforcement. In 2000, the SEC introduced Regulation FD (full disclosure), further limiting the information available to arbitrageurs. Any important information must be disclosed widely and publicly, rather than shared privately with a few.
This brings us to another aspect of the arbitrageur's job: Although it is commonly believed that the arbitrageur's job ends when a merger is announced (and cashed out after the underlying stock rises), in fact, the modern arbitrageur's job often begins at this time.
So, what exactly are arbitrageurs doing? Let's start with merger arbitrage, which has become the basis of plots for several Hollywood movies over the years.
Also known as risk arbitrage, merger arbitrage involves exploiting the price difference between the target company's share price and the acquiring company's proposed offer. When a merger is announced, the target company's stock price is often lower than the quoted price, reflecting the uncertainty or risk factors associated with the deal. Arbitrageurs often take action at this time, believing that the merger is more likely to be approved and that the target company's share price will eventually converge with the quoted price. They exploit this price gap by buying the target company's stock at a lower market price and then selling it at a higher offer price when the deal closes.
Once a merger or acquisition is announced, arbitrageurs start tracking the details of the deal. Their role is somewhere between a financial researcher and an investigative reporterassuming they report to just one public company. Arbitrageurs are discerning whether the trade will go through smoothly.
Their first step usually involves obtaining the relevant companies' annual and quarterly reports and 10-K filings to assess their financial health. The better the company's financial health, the more likely it is that the deal will close. Arbitrageurs also gather research from brokerage firms about both companies and their industries. Online databases and services greatly simplify this process. They also want to understand the industry and the rationale behind the deal. A strategically sound merger is not only a valuable addition to a portfolio, but is also more likely to be completed successfully.
The AT&T/Time Warner (announced in 2016; closed in 2018) and Disney/Fox (announced in 2017; closed in 2019) mergers present significant arbitrage opportunities. Both mergers faced legal challenges and regulatory scrutiny over concerns about media concentration. Delays allow arbitrageurs to track developments at every turn a court case here, a regulatory ruling there while calculating the likelihood that these trades will succeed.
Arbitrageurs are often financial generalists and must learn quickly because they may be focused on trading two manufacturing companies one day and move to a natural gas company focused on complex proven reserves and pipelines near the Black Sea the next. At every turn, arbitrageurs are trying to assess their companies’ potential rewards, risks and likelihood of the deal completing. Only after this can the arbitrageur determine which stocks to buy and what hedging strategies to adopt if the trade fails.
Between deal announcement and completion, the following issues may arise:
Attention to these risks makes merger arbitrage an ongoing process. Arbitrageurs may track the case's progress in Delaware courts. On the other hand, they may keep a close eye on global economic indicators and regulatory changes that could impact the success of a deal. Arbitrageurs will also constantly contact industry experts, legal advisors and other arbitrageurs to obtain information on any developments, market trends and changes in investor sentiment, and adjust strategies if necessary.
Here are some of the ways arbitrageurs try to profit from price differences that occur in different markets:
IMPORTANT NOTE: When an asset is listed on multiple markets, the price of the asset may not always be the same.
Let's look at an example of an arbitrageur at work. Suppose Company Traders can buy shares on the NYSE and then immediately sell the same shares on the LSE, making a profit of 5 cents per share, minus any transaction fees. Traders exploit this arbitrage opportunity until the NYSE professionals exhaust Company X's inventory, or the NYSE or LSE adjusts prices to eliminate the opportunity.
The rise of cryptocurrencies provides another opportunity for arbitrageurs. As the price of Bitcoin climbs, arbitrage opportunities arise from price differences across multiple global exchanges.
For example, Bitcoin trades at a premium on cryptocurrency exchanges in South Korea, a price difference known as the “kimchi premium” compared to trading in the United States, primarily because of the high demand for cryptocurrencies in these regions. Crypto traders profit from the price gap between these two locations in real time.
Arbitrageurs play an important role in the functioning of capital markets because they exploit price inefficiencies to make prices more accurate than they would be without intervention. When arbitrageurs buy an asset in a cheaper market and sell the same asset in a more expensive market, their actions often cause prices in the two markets to gradually converge. This results in prices being essentially equal across all markets.
In short, arbitrageurs help resolve pricing inefficiencies and inject liquidity into the market.
Arbitrageurs often use trading software designed specifically for algorithmic trading. This software is capable of processing real-time market data, analyzing the data, and quickly executing trades after processing. Additionally, many arbitrageurs use systems that are tailored to fit their specific trading strategies. These systems are typically equipped with powerful processors and high-speed internet connections to minimize trade execution time. Cloud computing and data analytics are critical in this process, as traders often need to store, process and analyze large data sets as they search for arbitrage opportunities across global markets.
Arbitrageurs face the risk that the expected convergence of asset prices may not materialize or take longer than expected, which could result in losses. Additionally, delays or failures in executing trades can also erode profit margins. In addition, in terms of liquidity risk, arbitrageurs also face the risk of not being able to buy or sell assets quickly at expected prices, which is related to thin market trading volumes. To reduce these risks, arbitrageurs often spread their investments across different arbitrage opportunities to avoid suffering significant losses in one area. They also use sophisticated risk management tools and techniques, including real-time monitoring systems and stop-loss orders, to limit potential losses. Many arbitrageurs also engage in hedging strategies to offset potential losses from market fluctuations.
High-frequency trading plays an important role in modern arbitrage strategies. High-frequency trading involves using complex algorithms to execute large numbers of orders at extremely high speeds. As with arbitrage, high-frequency trading allows traders to take advantage of brief price differences that may only exist for a fraction of a second between different exchanges or different securities. These algorithms can analyze market conditions, execute orders, and close positions in the blink of an eye, often before the market has a chance to correct these inefficiencies.
Arbitrageurs look for inefficiencies in the market and profit from them. These inefficiencies often relate to different quotes for the same asset on different exchanges. However, it may also mean delving into market movements, such as mergers and acquisitions, to profit from price differences in those deals.
Arbitrageurs usually work for large financial companies with huge resources, and their work helps to increase liquidity and make market prices more equal.
