An arbitrageur is a type of investor who attempts to profit from price inefficiencies in the market by making simultaneous trades. Essentially, they buy and sell the same asset on different markets or in different forms to take advantage of the price difference. This practice, known as arbitrage, is considered low risk and can provide high returns.


The phonetic pronunciation of the word “Arbitrageur” is: ahr-bi-truh-zhur.

Key Takeaways

  1. An Arbitrageur is an investor who seeks to profit from price differences in diverse markets or in forms such as in securities, commodities, or foreign exchange. They leverage these disparities by buying at a lower price and selling at a higher price.
  2. Arbitrageurs help in maintaining efficiency in the markets. Through their activities, they can assist in ensuring that the prices of securities, commodities or currency do not deviate substantially from their intrinsic value for lengthy periods of time.
  3. While arbitrage opportunities can present lucrative situations, they are often short-lived, and require swift actions. They also often involve significant capital, research and technology to identify and exploit these opportunities before they disappear. Additionally, they also contain inherent risks as market conditions can shift rapidly.


An arbitrageur plays a significant role in financial markets as they help to ensure market efficiency by taking advantage of price discrepancies. They buy securities at a lower price in one market and sell them at a higher price in another, thus profiting from the price difference. This process, known as arbitrage, also assists in maintaining price uniformity across different markets as the arbitrageur’s activities work to eliminate pricing inefficiencies. Without arbitrageurs, markets might experience more significant pricing disparities, hampering their overall effectiveness and efficiency. Therefore, the role of an arbitrageur is considered vital to maintaining market equilibrium and integrity.


An arbitrageur plays a fundamental role in the efficient functioning of financial markets. An arbitrageur’s main purpose is to capitalize on price discrepancies in different markets for the same asset. So, they buy an asset at a lower price in one market and sell it at a higher price in another market, achieving a risk-free profit. This profit is made because of the ‘inefficiency’ in the markets, which fails to accurately set the same price for an asset globally. Their purpose, overall, is making money from these market inefficiencies, providing a mechanism that pushes the markets toward efficiency.Arbitrageurs also play an important stabilizing role in global financial markets. By exploiting arbitrage opportunities, they help to ensure that asset prices in different locations or platforms do not deviate significantly over a sustained period. This fosters market efficiency and price uniformity. Additionally, arbitrageurs’ activities provide liquidity, limit price volatility and help in accurate price discovery in the markets. Despite the potential for quick and ensured profits, it requires a high level of expertise, fast execution, and significant capital to effectively venture into arbitrage trading, hence why it’s primarily carried out by financial institutions and hedge funds.


Arbitrageur is a type of investor who aims to profit from price differences in different markets. Here are three real-world examples relevant to the term:1. Currency Exchange – A common example of arbitrage is in the foreign exchange market. An arbitrager might buy a large amount of US dollars in the UK where they might be cheaper, and then sell them in the USA where they can sell for a higher price. This is a form of Spatial Arbitrage.2. Stock Market – Arbitrage is common in the stock market. An example might be a trader who buys a share on the New York Stock Exchange for $50 and simultaneously sells it on the London Stock Exchange for $50.50. The difference in price presents a risk-free profit opportunity for the arbitrageur.3. Mergers and Acquisitions – In the world of mergers and acquisitions, an arbitrageur might buy stocks of a company being acquired while short selling the acquiring company’s stocks. The anticipation here is that the acquired company’s stock will increase, while the acquiring company’s stock will fall, thus giving the arbitrageur a profit from the price discrepancy. This is often referred as Risk Arbitrage or Merger Arbitrage.In all these cases, the aim for arbitrageurs is to take advantage of discrepancies in prices in different markets. They essentially buy an asset at a lower price in one market and sell it at a higher price in another, thereby making a profit without any net cash investment.

Frequently Asked Questions(FAQ)

What does the term Arbitrageur mean in finance and business?

An Arbitrageur is an individual or entity that exploits the price differences of a single asset or similar assets in different markets to make a profit. This practice, known as arbitrage, is considered low-risk and can include securities, currency, or commodities trading.

What does an Arbitrageur do?

An Arbitrageur capitalizes on price discrepancies in different markets. They buy at a low price in one market and simultaneously sell at a high price in another market, thus profiting from the price difference.

How do Arbitrageurs contribute to market efficiency?

Arbitrageurs help increase market efficiency by ensuring price uniformity across different markets. They exploit price differences which, in turn, decreases the price in the more expensive market and increases it in the cheaper market, until the prices become roughly equal.

Is Arbitrage risk-free?

While arbitrage is often considered a low-risk activity due to the simultaneous buy-and-sell nature of the transactions, it is not entirely risk-free. Risks include price changes occurring before the transaction is complete, transaction costs, and market liquidity issues.

What kind of trades do Arbitrageurs typically make?

Arbitrageurs often deal in a wide range of trades, including securities, commodities, currency, and derivatives arbitrage. They also participate in merger and acquisition arbitrage, taking advantage of price discrepancies between the current price and the final purchase price of a company’s stock.

What is required to be a successful Arbitrageur?

A successful Arbitrageur typically requires sophisticated trading systems to identify and exploit price discrepancies quickly. They also need a solid understanding of the markets, large amounts of capital, and the ability to act quickly on opportunities.

Do Arbitrage opportunities exist for average investors?

Generally, Arbitrage opportunities are swiftly identified and acted upon by professional Arbitrageurs, and are therefore difficult for average investors to spot and capitalize on. Also, the large capital required for arbitrage usually puts it out of reach for most retail investors.
