Types of Arbitrage

Arbitrage can help traders use temporary price differences. The basic idea is simple: buy at a lower price and sell at a higher price.

• Pure arbitrage uses market price differences.
• Retail arbitrage involves reselling physical products.
• Risk arbitrage depends on future events.
• Convertible arbitrage uses bonds and shares.
• Merger arbitrage focuses on company deals.
• Dividend arbitrage works around dividend dates.
• Futures arbitrage uses cash-futures price differences.

Suppose the same asset is available for ₹45 in one market and ₹52 in another.

A trader may buy it for ₹45 and sell it for ₹52. The difference is ₹7 per unit before considering other costs.

That is the basic idea behind arbitrage.

An asset should normally have similar prices across markets. However, prices can temporarily move apart because markets react differently to demand, interest rates, company events, and other factors.

An arbitrage trader tries to spot this difference before it disappears.

The key point is speed. Once more traders notice the price difference, buying and selling can bring the prices closer together. The opportunity can then disappear.

This is why arbitrage may sound simple but can be difficult to carry out in practice. A trader has to find the price difference, check the costs, and execute the required trades at the right time.

Arbitrage trading is not limited to one method. The approach changes depending on what is being bought and sold and why the price difference exists.

Here is a quick view:

Pure arbitrage

Pure arbitrage means buying the same asset at a lower price in one market and selling it at a higher price in another.

For example, if an asset costs ₹45 in Market A and ₹52 in Market B, the price difference is ₹7 per unit. Trading costs and price changes can reduce this amount.

Retail arbitrage

Retail arbitrage involves buying a physical product at a lower price and reselling it at a higher price.

For example, a product bought for ₹500 and sold for ₹650 has a ₹150 price difference. Delivery charges, platform fees, and other costs reduce the final amount.

Risk arbitrage

Risk arbitrage depends on a future event, such as a merger or acquisition.

A trader may buy shares of a target company if they trade below the announced deal price. If the deal succeeds, the gap may narrow. If it fails, the trader may face a loss.

Convertible arbitrage

Convertible arbitrage uses price differences between convertible securities and the related company shares.

A trader may buy a convertible bond and take an opposite position in the shares. Share prices, interest rates, credit quality, and liquidity can affect the result.

Merger arbitrage

Merger arbitrage focuses on announced mergers and acquisitions.

A target company’s shares may trade below the deal price because the transaction may face delays or fail. Traders try to benefit if the price gap narrows when the deal is completed.

Dividend arbitrage

Dividend arbitrage involves trading around dividend dates.

The share price may adjust on the ex-dividend date, so receiving a dividend does not automatically mean extra profit. Traders consider both the dividend and the related price movement.

Futures arbitrage

Futures arbitrage uses price differences between the cash and futures markets.

If the futures price is high compared with the cash price, a trader may buy in the cash market and sell the futures contract. The opportunity depends on the price gap remaining large enough after costs.

Arbitrage tries to benefit from a price difference.

For example, if an asset costs ₹100 in one market and ₹105 in another, the price gap is ₹5 per unit. A trader may buy at ₹100 and sell at ₹105.

However, the ₹5 difference is not guaranteed profit. Trading costs and price movements can reduce the final amount.

A visible price gap does not always turn into profit.

Brokerage, taxes, exchange charges, low liquidity, and fast price movements can reduce the available gain. In merger or risk arbitrage, the deal may also get delayed, changed, or cancelled.

Traders should calculate all costs before acting on an arbitrage opportunity.

Arbitrage looks simple because the basic idea is to buy at a lower price and sell at a higher price. But real trades can be more difficult. Prices can change quickly, and trading costs can reduce profit. Some strategies also depend on mergers, dividends, or futures prices moving as expected. So, traders need speed, proper research, and a clear understanding of the risks. A price difference does not always mean guaranteed profit.
