What is Arbitrage?
Arbitrage in India is an investment strategy wherein the investor exploits a variation in prices of the same financial instrument on different markets or exchanges. For example, a stock can be listed on BSE and simultaneously on NSE, and there may be slight variations in prices on both of these exchanges. Arbitrage traders can then buy on one exchange where it is cheaper and sell on another where it is priced higher, thereby locking in a riskless profit.
This is also practiced in India's commodity and Forex markets. The difference in prices of commodities like gold or crude oil, whether in the case of spot or futures, provides the avenue for arbitrage. Similarly, Forex traders take advantage of such avenues through the difference in the rate of exchange of currencies across different platforms or banks.
This is a popular strategy amongst Indian investors, with minimal risk and a short duration of trade. Apart from this, retail investors also take part in this form of trading strategy through arbitrage funds, which are a class of mutual funds that make the most of such price differences. By doing so, they help enhance the efficiency and liquidity of markets.
How Does Arbitrage Trading Work?
Arbitrage trading in India works by exploiting the price difference of the financial instrument across BSE and NSE or commodity markets, such as MCX. Suppose a certain stock is quoting ₹1,000 on BSE and ₹1,010 on NSE. In such a scenario, an arbitrageur can buy the stock on BSE and sell it simultaneously on NSE, thereby earning a profit of ₹10 per share. It relies on the use of sophisticated tools and complex algorithms to spot price discrepancies in an instant.
More often than not, it occurs over algorithmic trading platforms for which Indian traders use their own tools or those provided by the brokers for execution in the quickest time. This is because price gaps, due to market forces, usually get corrected within a few seconds. In the commodity space, arbitrage opportunities come from differences between spot prices and futures contracts on platforms like MCX. Forex arbitrage is also a common thing, where traders exploit rate differences in INR against foreign currencies across banks or online platforms.
Since transaction costs and taxes like the Securities Transaction Tax (STT) impact profits, low-cost brokers and an efficient platform are crucial in arbitrage. This trading strategy will help the trader make small but steady profits. The strategy also adds to market stability and price uniformity between exchanges.
When Does Arbitrage Take Place?
Arbitrage arises out of price differences that might occur for the same financial instrument across exchanges or markets. This usually happens during times of high market volatility, different demand-supply conditions, or immediately following major financial announcements such as budget declarations or company results.
This means that if a particular equity is listed on the BSE and NSE, it may be trading marginally differently in both markets because of a difference in liquidity or order flow. In the same way, arbitrage is common in the futures and spot markets for commodities such as gold, where prices fluctuate based on global trends and local factors.
Arbitrage opportunities come in a more frequent manner during market opening and closing hours. They also come when global markets (like the US or Europe) influence the markets in India. Traders must act quickly, as these inefficiencies do not last for a very long time. They get corrected as soon as participants exploit them.
1. Cash-Futures Arbitrage
This especially includes exploiting the price difference between the stock's spot price and its futures price. The trader buys the stock in the cash market - a typical example is NSE- and sells its futures contract on the same exchange to lock in the profit.
2. Index Arbitrage
It involves exploiting the difference between the actual index value -for example, Nifty 50- and the corresponding index futures price. Traders initiate by buying or selling the constituent stocks of the index and then proceed to take parallel trading positions in futures to gain from the two prices' convergence.
3. Cross Market Arbitrage
This is buying and selling the same stock listed on BSE as well as NSE. Price divergence due to differences in liquidity results in arbitrage opportunity.
4. Commodity Arbitrage
Traders take advantage of the difference between spot and futures prices of commodities like gold or crude oil on exchanges like MCX.
5. Forex Arbitrage
Involves exploiting the different currency rates, for example, INR/USD, across various banks, online forex platforms, or different time zones.
6. Crypto Arbitrage
Though falling under different regulations, traders of India buy and sell cryptocurrencies across WazirX and CoinDCX to redundantly exploit price differences.
What is Arbitrage?
1. Understand Market Regulations
Arbitrage traders in India must comply with SEBI regulations. Understanding legal frameworks, including taxes like STT and GST, ensures smooth trading without penalties.
2. Use Algorithmic Trading Tools
Speed is essential in arbitrage trading as price discrepancies are short-lived. High-frequency trading platforms help identify and execute trades quickly across BSE, NSE, and MCX.
3. Optimize Transaction Costs
Choose low-cost brokers to minimize fees and taxes. Reducing transaction costs ensures that narrow profit margins remain viable.
4. Focus on Liquid Assets
Liquidity ensures faster trade execution without price slippage. Focus on high-volume stocks, index derivatives, or commodities to enhance profitability.
5. Diversify Arbitrage Strategies
Explore multiple avenues like cash-futures arbitrage, commodity arbitrage, and cross-market arbitrage to spread risk and maximize opportunities.
6. Monitor Global Markets
International markets influence Indian assets, creating arbitrage opportunities. Stay informed about global economic developments.
7. Practice Risk Management
Even low-risk strategies like arbitrage carry operational risks such as trade execution delays. Employ stop-loss orders and position sizing to manage risks effectively.
8. Evaluate Arbitrage Funds
Mutual funds specializing in arbitrage can be a safer, low-effort way to profit from price differences, especially for new investors.
