In the Indian stock market, arbitrage is the practice of simultaneously purchasing and selling stocks in different industry sectors to profit from the price disparity. As an example of arbitrage, a stock may be bought at a discount on the National Stock Exchange (NSE) and afterwards sold at a premium on the Bombay Stock Exchange (BSE). This is possible with the use of complex algorithms and trading systems, but it is typically seen as a high-risk tactic. The article delves into the concepts of arbitrage, its functioning, and the conditions that govern it. Additionally, it explores the associated risks involved in engaging in arbitrage within the stock market.

Defining Arbitrage

The practice of concurrently purchasing and selling stocks in several marketplaces is known as arbitrage in the Indian stock market.

  • The goal is to capitalise on the price discrepancy.
  • It is a strategy for generating income by taking advantage of the price difference between two or more markets.
  • Due to the simultaneous purchase and sale of the same securities in many markets, it is risk-free trading.
  • Considering how difficult it is to spot and take advantage of arbitrage opportunities, it is widely regarded as a high-risk technique that can be used by both individuals and institutional investors.

Risks of Arbitrage in the Stock Market

Arbitrage in the share market carries a number of risks, including:

  • Timing Risk: Arbitrage chances can vanish fast. So, timing is essential. The chance could be missed if a trader is unable to complete it quickly enough.
  • Liquidity Risk: It may be challenging to complete the trade at the intended price if the market in which the investor is trading equities is not liquid.
  • Market Risk: The direction of the market as a whole could abruptly alter, which could have an effect on how much stocks cost to trade.
  • Regulatory Risk: There is always a possibility that the regulatory process may alter, which could have an impact on the capacity to carry out arbitrage transactions.
  • Execution Risk: There is a chance that trades won’t go through as expected. Technical problems, mistakes, or other unforeseen circumstances may be to blame for this.
  • Margin Risk: Arbitrage deals are typically made on margin, which means that investors are borrowing money to make the trade. As a result, the probability of losses is raised.
  • Brokerage: Making a lot of trades is necessary for arbitrage trading. As a result, brokerage fees are expensive, which may hurt profitability. Arbitrage in the stock market is seen as a high-risk tactic that needs a great deal of expertise, knowledge, and resources to perform successfully.

Working of Arbitrage

Arbitrage, as used in the stock market, means taking advantage of price disparities between several marketplaces or segments. This can be achieved simultaneously by purchasing and selling the same stock in other markets or by simultaneously purchasing and selling comparable stocks that are most likely to move in the opposite direction. An investor might observe, for instance, that a stock is selling for less on the Bombay Stock Exchange than on the National Stock Exchange. The investor can purchase the stock on the NSE and sell it at the same time on the BSE, earning money from the price differential.

Buying and selling equities that are related to one another and are anticipated to move in opposing directions is known as ‘statistical arbitrage’, and it is another example of arbitrage. For instance, an investor might purchase a stock in one industry and simultaneously sell a stock in another industry that will probably be impacted by the same market conditions. Investors usually use very advanced algorithms and trading systems to quickly find and take advantage of arbitrage possibilities. Arbitrage trades are typically executed on margin, which means that investors borrow funds to complete the transaction. Losses are now more likely as a result.

Arbitrage Requirements

Yes, some requirements must be fulfilled to carry out profitable arbitrage trades in the stock market. These consist of:

  • Difference in Market Price: The most fundamental need for arbitrage is that there must be a price discrepancy between the various markets or market segments in which the stock is traded.
  • Market Efficiency: Only in imperfectly efficient marketplaces do arbitrage opportunities arise. In other words, there would be no chance for arbitrage if the value of a stock were the same in all markets.
  • Liquidity: The marketplaces or segments in which the stock is being traded must be liquid to carry out arbitrage trades. This means that a sufficient number of buyers and sellers must be willing to exchange the stock at the specified price.
  • Timing: It is essential since arbitrage opportunities might vanish quickly. To benefit from the price differential, investors must be able to spot opportunities and place trades swiftly.
  • Margin: Arbitrage trades are typically executed on margin, which requires investors to borrow funds. As a result, the probability of losses is raised.
  • Regulatory: An environment that permits the execution of arbitrage trades must exist.
  • Brokerage: Making a lot of trades is necessary for arbitrage trading. As a result, brokerage fees are expensive, which may hurt profitability.

Overall, arbitrage trading requires a high level of skill and is not recommended for beginners because of its demanding requirements. To execute it successfully, a lot of talent, information, and resources are needed.


Arbitrage stands as one of the oldest financial strategies, requiring traders to closely monitor market activities and fluctuations in asset prices. Profiting from trading stocks and other commodities becomes feasible when identifying arbitrage opportunities. However, executing successful arbitrage trades is challenging and demands significant expertise. The dynamic nature of the stock market’s volatility leads to ever-changing arbitrage opportunities, requiring continuous observation. Additionally, completing trades at the intended price can be challenging due to the market’s sensitivity to even minor changes in circumstances impacting stock values.
