Arbitrage Trading

Arbitrage trading has grown profitable for sharp investors looking to invest and profit from price inefficiencies across different markets. In recent years, arbitrage trading in India has caught a huge attention. With the fast-changing financial landscape in the country, its domestic markets are now getting integrated with their global counterparts like never before.

What is Arbitrage Trading?

The term "arbitrage trading" is the practice of selling and buying an identical asset or related securities simultaneously but in different markets or forms, aiming to gain from the price differences that may only be momentary. The strategy allows locking in these price differences and deriving risk-free profits due to temporary mispricing of the assets.

How Arbitrage Trading Works

The essence of arbitrage trading lies in the one-price law, which states that following the deduction of transaction and conversion fees, identical assets should have the same price in all markets. However, these may indicate price differences, giving room for arbitrageurs because of market inefficiencies, liquidity differences, and information gaps.

To execute an arbitrage trade, traders first identify the mispriced asset across different markets or securities. At the same time, they sell the asset in the market where it is overvalued and buy it in the market where it is undervalued. In the process of price convergence, the arbitrageur closes the positions he is holding by locking in a risk-free profit equal to the difference in prices and fewer transaction costs.

Types of Arbitrage Trading

Generally, arbitrage trading incorporates different approaches. The common types of arbitration trading include the following:

  1. Cash-and-Carry Arbitrage: The investor buys the asset on the market for a lower price. When the futures market has a higher price for the same asset, the investor will separate the profit earned in between.
  2. Convertible Arbitrage: This strategy taps into the price anomaly window when one convertible bond trades cheaper than another convertible bond and its linked stocks. This is a long hedge strategy where the trader is uncertain if they ought to invest in an undervalued convertible bond, and they have sold the accompanying stock to make the most of the pricing anomaly.
  3. Statistical Arbitrage: This strategy uses complex quantitative models to identify and take advantage of temporary mispricing between related securities or portfolios based on historical correlations and statistical relationships.
  4. Merger Arbitrage: It is the condition under which a particular company, acquiring or merging with another company, makes traders profit by making a bet on the difference between the target company's stock price and proposed acquisition price in case the deal is completed.
  5. Index Arbitrage: This type of arbitrage is where arbitrageurs seek to capitalise on the price differentials between a stock index and its underlying component stocks or related derivative instruments (but not limited to futures or exchange-traded funds (ETFs)).

Arbitrage Trading in India

Long and short, financial instruments, derivatives, and the increasing importance of institutional investors have generated a boom in arbitrage trading. India's well-known arbitrage trade tactics result from mark-to-market (MTM) price disparities, which push the spot's needless movement to the perfect goal.

Separating equities and derivatives trading exchanges, such as the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE), into separate entities would open up arbitrage opportunities, assuming price inefficiencies exist between these platforms. Other earning opportunities in India are on dual-listed stocks, which show a difference in price as the same company shares are traded under two different exchanges. Traders, therefore, could take advantage of these price variances and make simultaneous purchases and sales across exchanges, thereby capturing the price differences.

Apart from this, with the advent of exchange-traded funds (ETFs) and index funds in India, index arbitrage strategies also obtained scope for implementation. In such a case, the trader may take an offsetting position in the two markets and, hence, realise gains on the temporary mispricing between the ETF or index fund and its underlying basket of securities. 

Strategies for Successful Arbitrage Trading

The concept of trading arbitrage might look very plain in theory. Still, to make this trade successful, a well-defined strategy has to be embraced with due consideration accorded to risk management. A few essential strategies for arbitrage trading include:

  1. Speed and ExecutionArbitrage trading is generally a practice of essence in time, given that the nature of price inefficiencies is typically short. The trader requires fast trading platforms with sharp executions to capture fleeting opportunities.
  2. Risk ManagementArbitrage trading is low in associated risk but lacks one. The execution slippage and market price volatility, with possibilities of liquidity constraints in different markets, may determine the quantum of profit—sound risk management techniques, including position sizing and stop-loss orders, back this.
  3. Diversification: If we compare the different types of assets and the various arbitrage techniques, we will surely obtain better returns and, consequently, better risk management. Products like shares, which are included in the asset class bonding, as well as commodities and currencies, may be exposed to traders.
  4. Automation and Algorithmic Trading: The recent rise of algorithmic trading has become very popular among those who trade based on arbitrage. Those systems regularly discover and immediately execute their other assets exchange alternatives with hardware applications that far surpass any human speed.
  5. Regulatory Compliance: Some rules are named by regulatory bodies, such as the SEBI (Securities and Exchange Board of India), and there are also many guidelines for trading arbitrage in India. A trader must adhere to the rules and guidelines strictly because those rules if broken, expose him to the threat of penalties and allow him to engage in legal battles to save himself.


In Indian trading, the arbitrage phenomenon is very important as it provides a trader with the risk of manipulating the market imperfection and pocketing a very low-risk profit. The possibility of having immense money at the end of the day seems profitable. Yet, it also requires complete acknowledgment of the market’s mechanism, capable risk management, and the ability to execute orders extremely fast. The line between Indian financial markets and their foreign equivalents may be further blurred to become one unity later. Consequently, this can lead to even more locations for arbitrage trading, providing more benefits for clever traders looking for an alternative investment to diversify their portfolio.
