Arbitrage: How Arbitraging Works in Investing, and with Examples

Arbitrage is the simultaneous purchase and selling of a single asset or a group of related assets in various markets through variations in the asset’s quoted price. It takes advantage of brief fluctuations in the cost of identical or comparable financial products on several markets or in various formats. Market inefficiencies give rise to arbitrage, which both takes advantage of and corrects them.

Recognizing Arbitrage

Any time a stock, commodity, or piece of money can be bought at one price on one market and concurrently sold at a greater price on another, arbitrage can be employed. The circumstance offers the trader the chance to benefit without taking any risks.

Arbitrage offers a way to ensure that prices don’t diverge significantly from fair value over an extended period. Technology improvements have made it very challenging to profit from price mistakes in the market. Many traders use automated trading programs configured to track changes in similar financial instruments. Any ineffective price structures are often addressed immediately, frequently within a few seconds, and the opportunity is lost.

Illustrations of Arbitrage

As a simple illustration of arbitrage, think about the following: On the New York Stock Exchange (NYSE), the stock of Company X is now selling for $20, while on the London Stock Exchange (LSE), it is currently trading at $20.05.

A trader can purchase the stock on the NYSE and sell the identical shares on the LSE right away to make a 5-cent profit on each share.

The trader can keep taking advantage of this arbitrage until the NYSE specialists run out of Company X’s shares or until the NYSE or LSE specialists modify their pricing to eliminate the opportunity.

A Complex Example of Arbitrage

Triangular arbitrage is used in Forex or currency markets as a tougher example. In this instance, the trader converts one currency to another and then transfers that second currency to a third bank before returning the third currency to the first.

Assume you are given the following conversion rates for your $1 million: USD/EUR = 1.1586, EUR/GBP = 1.4600, and USD/GBP = 1.6939.

There is a chance to make money by arbitraging certain currency rates:

  • Exchange dollars for euros: €863,110 equals $1 million multiplied by 1.1586.
  • Convert euros to pounds: £591,171 x 1.4600 = €863,100
  • Convert pounds into dollars: £591,171 × 1.6939 = $1,001,384
  • Take the original investment out of the total: $1,001,384 – $1,000,000 = $1,384
  • You would make an arbitrage profit of $1,384 from these deals (assuming no transaction fees or taxes).

How does arbitration operate?

Trading called “arbitrage” takes advantage of the minute price discrepancies between identical or comparable assets in two or more marketplaces. The arbitrage trader purchases the item on one market and sells it on another to profit from the price difference. This situation has more intricate permutations, but they all hinge on finding market “inefficiencies.”

Arbitrage traders, or arbitrageurs, often work for major financial organizations. It often entails trading a substantial sum of money, and the split-second chances it presents may only be recognized and taken advantage of using extremely sophisticated algorithms.

What Are a Few Arbitrage Examples?

The practice of purchasing and selling shares of stocks, commodities, or currencies on several markets to take advantage of the unavoidable fluctuations in their pricing from minute to minute is known as arbitrage.

However, other trade practices have also been called “arbitrage” in various instances. One tactic that is well-liked among hedge fund investors is merger arbitrage, which is purchasing firms’ shares ahead of a merger that has been announced or is anticipated.

Arbitrage: Why Is It Important?

Arbitrage traders improve the financial markets’ effectiveness while working to increase their profits. The price discrepancies between identical or comparable assets get less when bought and sold. While the higher-priced assets are sold off, the lower-priced ones are bid up. Arbitrage corrects price inefficiencies in this way while also bringing more liquidity to the market.

The Verdict Arbitrage is a situation in which you may simultaneously acquire and sell a product or asset that is comparable to another at different prices and make a profit without taking on any risk.

According to economic theory, arbitrage shouldn’t be possible because there wouldn’t be any chances for profit if markets were efficient. In actuality, arbitrage may occur, and markets can be inefficient. However, arbitrageurs try to bring prices back into line with market efficiency when they spot and then fix such mispricings (by buying them cheap and selling them high). As a result, any arbitrage possibilities that do arise are transient. There are several different arbitrage methods, some of which include intricate connections between various assets or securities.


  • Arbitrage is the simultaneous acquisition and disposal of an asset in many marketplaces to take advantage of minute price variations.
  • Trades in stocks, commodities, and currencies are all examples of arbitrage.
  • Arbitrage makes use of the inescapable market inefficiencies.
  • But arbitrage gets markets closer to efficiency by taking advantage of inefficiencies.
