What is Arbitrage Trading?

Arbitrage trading is a strategy that usually takes advantage of price differences for identical or similar assets in different markets. Traders, often working for large financial institutions, purchase the asset in one market and sell it in another at the same time and profiting from the price disparity. This practice relies on identifying market inefficiencies and requires advanced software to capitalize on split-second opportunities. While markets are generally considered efficient, temporary discrepancies in supply and the demand create opportunities for arbitrage.

Currency and stock markets are particularly prone to such opportunities. However, these chances are short-lived, lasting only seconds or minutes, necessitating swift execution. Arbitrage can be lucrative, especially when dealing with significant sums, making it a favored strategy for hedge funds and experienced investors. It encompasses various types, including pure, merger, and convertible arbitrage, with global macro serving as a related investment strategy focused on economic disparities between countries.

Overall, arbitrage trading involves leveraging price differences between markets to generate risk-free profits by simultaneously buying and selling assets. It is executed through advanced software and is commonly practiced by institutional investors seeking to exploit market inefficiencies.

Types of Arbitrage

Pure Arbitrage

Pure arbitrage is an investment strategy that involves simultaneously buying and selling a security in different markets to exploit price differences. It occurs when an asset is traded in multiple markets, creating temporary price discrepancies.

For instance, if a stock is priced at $1.05 on the NYSE and $1.10 on the London Stock Exchange, an investor can buy it for $1.05 and sell it for $1.10, making a small profit. Pure arbitrage can also occur in foreign currency exchange rates.

However, with advancements in technology and digital trading, identifying and resolving pricing errors has become faster, making pure arbitrage less common.

Merger Arbitrage

Merger arbitrage which is also known as risk arbitrage, is a strategy that involves profiting from the merger or acquisition of publicly traded companies. Traders buy shares of a target company, anticipating that the stock price will rise as the deal progresses towards completion.

The target company’s stock typically trades at a slight discount to the announced deal price due to the risk of the deal falling through. Traders aim to sell their shares at a higher price once the merger is successfully completed.

However, there is a risk involved as the deal may not materialize or the shares may not be sold at the desired value. Shorting the target company’s stock is another variation of this strategy.

Convertible Arbitrage

Convertible arbitrage is an investment strategy that involves taking advantage of price discrepancies between convertible bonds and the underlying company’s stock.

Convertible bonds are a type of corporate debt that can be converted into shares of the company at a later date. By simultaneously holding long and short positions in the convertible bond and the stock, investors can profit from differences in their prices. If the bond is considered cheap, investors may take a short position on the stock and a long position on the bond.

Conversely, if the bond is considered overpriced, investors may take a long position on the stock and a short position on the bond.

How Arbitrage Works

Arbitrage is an investment strategy where traders exploit price differences for the same asset in different markets. Nowadays, sophisticated algorithms are used to discover and capitalize on these opportunities. Price discrepancies often involve different geographic locations or information delays, such as in foreign exchange or stock trading. Institutional investors and hedge funds may employ statistical arbitrage, using algorithms to identify temporary price mismatches between related securities.

However, arbitrage requires large amounts of money and multiple transactions to generate significant returns, making it an expensive approach. While markets are not perfectly efficient, the small price differences and the quick disappearance of arbitrage opportunities limit its profitability.

Tips for Arbitrage Trading

  • Exchange-to-exchange trading involves buying in one exchange and selling in another, but be cautious as a small price difference may not always indicate an arbitrage opportunity.
  • Analyze the bid price (buying price) and offer price (selling price) in different exchanges to determine which one is higher.
  • Consider transaction costs in the share market, as high costs can negate any gains from arbitrage.
  • In futures arbitrage, monitor the price difference between the cash or spot market and the futures contract, known as the basis. Higher basis provides better trading opportunities.
  • Keep an eye on the cost of carry (CoC) associated with holding a position until the futures contract expires. Negative CoC occurs when futures trade at a discount to the cash market, allowing for reverse cash and carry arbitrage.
  • Explore buyback arbitrage when a company announces buying back its shares, as price differences may arise between the trade price and the buyback price.
  • Consider arbitrage opportunities resulting from price disparities between the cash and derivatives markets when a company announces a merger.


Automated systems are commonly utilized for arbitrage trading due to the fleeting nature of price differentials. While identifying arbitrage opportunities may be relatively straightforward, manually capitalizing on them is challenging and necessitates substantial investments.
