The Types and Strategies of Arbitrage Trading

Arbitrage is a powerful trading concept that capitalizes on the price discrepancies in different markets to make a profit. By buying low in one market and selling high in another, arbitrage traders are able to pocket the difference without a net investment. The idea behind arbitrage trading is relatively simple, but it requires meticulous planning and swift execution. In this article, we will explore into the different types of arbitrage and discuss several trading strategies associated with it.

There are several types of arbitrage trades:

1. Classic Arbitrage

Classic arbitrage refers to the practice in investment and financial markets where an asset or security is bought in one market and simultaneously sold in another market at a higher price, thus considered risk-free profit for the arbitrageur. Classic arbitrage leverages the price differentials of a specific asset between different markets or in different forms within a market.

The prerequisites for classic arbitrage are threefold: the same asset does not trade at the same price on all markets (the “law of one price” is temporarily violated), two assets with identical cash flows do not trade at the same price, and an asset with a known price in the future does not trade today at its future price discounted at the risk-free interest rate (or the asset has significant costs of storage; as such, it is not a riskless arbitrage).

However, these opportunities are often hard to find and require relatively sophisticated trading systems, and the systems need to process large amounts of data in real-time to detect arbitrage opportunities.

2. Retail Arbitrage

Retail arbitrage is a type of arbitrage that involves purchasing a product in one market, typically at a lower price, and then selling it in another market (often online) at a higher price. The goal is to capitalize on price differences between different markets.

A common example is purchasing a product at a discounted rate from a retail store and then selling it online through marketplaces such as eBay or Amazon at a higher price. The profit is the difference between the two prices, less the costs associated with the sale (such as shipping and platform fees).

The benefits and risks of retail arbitrage revolve around supply and demand. The primary risk lies in the possibility of being unable to sell the product at a high enough price to cover the initial cost and make a profit. Another risk is overestimating the demand for a product and being left with unsold inventory.

3. Merger Arbitrage

Merger arbitrage, also known as risk arbitrage, is an investment strategy that speculates on the successful completion of mergers and acquisitions. An investor that employs this strategy is known as an arbitrageur.

The primary risk in merger arbitrage is deal risk, should the deal fail to close due to antitrust concerns, financing issues, or a range of other reasons. The deal spread is the gross return to the merger arbitrageur in the event the deal successfully closes.

Merger arbitrage is typically not the domain of individual investors as it requires significant resources and expertise, including the ability to understand merger contracts in detail. Many hedge funds employ teams of lawyers and industry experts to help evaluate deal risk and merger arbitrage opportunities.

4. Convertible Arbitrage

Convertible arbitrage is a type of equity long-short investing strategy often employed by hedge funds. It involves the simultaneous purchase of convertible securities and the short sale of the same issuer’s common stock.

The premise of the strategy is that the convertible is sometimes priced inefficiently relative to the underlying stock, for reasons ranging from illiquidity to market psychology. In particular, the negative convexity of the issuer’s callable convertible bond may not be appropriately priced by the market.

Under this strategy, as the price of the underlying common stock falls, the investor shorting the stock should benefit from the decrease in the price of the shorted stock. Conversely, as the price of the underlying stock rises, the investor benefits from the appreciation of the convertible security. Thereby, the investment strategy seeks to yield significant returns with reduced volatility.

5. Triangular Arbitrage

Triangular arbitrage is the process of trading out of the first currency into a second, into a third, and then back into the first currency in a short amount of time. The purpose of triangular arbitrage is to take advantage of a discrepancy in prices and make a profit without any net cash flow. In other words, there is no investment or withdrawal of funds.

In the foreign exchange market, triangular arbitrage is a method that uses offsetting trades to profit from price discrepancies among different currency pairs. This arbitrage strategy involves three trades: exchanging the initial currency for a second, the second currency for a third, and finally the third currency back to the initial.

While theoretically profitable, in practice, significant barriers to successful triangular arbitrage exist in the form of transaction costs, market liquidity, and competition.

6. Pure Arbitrage

Pure or spatial arbitrage is an inter-market arbitrage of the same product if its price is not the same in different markets. The opportunity to enter spatial arbitrage arises when a price discrepancy occurs between markets, and the arbitrager could make a risk-free profit by simultaneously purchasing the asset at a lower price and selling it at a higher price.

Spatial arbitrage can occur in various markets, including stocks, currencies, and cryptocurrencies. The critical point is that these discrepancies usually only last for a short period because the price in the lower-priced market will tend to increase due to increased demand, and the price in the higher-priced market will tend to decrease due to increased supply until the prices equalize.

As the world becomes more and more interconnected, these opportunities are becoming less frequent. Automated trading systems have also made these opportunities less common, as they are capable of spotting and exploiting arbitrage opportunities much faster than human traders.

Pros and Cons of Arbitrage

Arbitrage is an intriguing aspect of the financial world. However, like all financial strategies, arbitrage comes with its pros and cons that investors need to understand before diving in.

Pros of Arbitrage

• Unambiguity: The beauty of arbitrage, in its purest form, is that it offers an investor a risk-free return, whereas most types of investments carry some form of risk.
• Less uncertainty: Unlike traditional strategies that depend on whether the market will rise or fall, arbitrage takes advantage of the market inefficiency, without any prediction.

Cons of Arbitrage

• Costs: There is a high entry barrier in the form of expensive automated trading systems, which could be out of reach for many investors.
• Execution risks: If one of the trades fails to execute correctly, the strategy may end up being a losing one.

3 commom Arbitrage Trading Strategies by traders

Here are three types of arbitragestrategies commonly used by traders:

1. Risk Arbitrage Strategy

Risk arbitrage, often known as merger arbitrage, takes advantage of the fact that the stock of a company being acquired usually trades below the price that the acquiring company is paying. This happens because there’s always a risk that the deal won’t go through, often due to regulatory issues.

Traders buy shares of the target company after the deal is announced and then wait for the acquiring company to buy them at a higher price. If the deal goes through, they make a profit. However, if the deal fails, the stock will likely fall back to its pre-deal price, leading to losses.

This strategy involves careful research to understand the likelihood of a deal being completed. It’s also essential to keep in mind that even if a deal seems likely to go through, unforeseen events can always derail it.

2. Fixed Income Arbitrage

Fixed income arbitrage is a hedge fund strategy that profits from the interest rate differentials between various fixed-income securities such as government bonds, treasury bills, and swaps. Traders identify two or more fixed income securities that, based on historical trends and market analysis, should have a specific price relationship.

Typically, one would short the overpriced security and go long on the underpriced, expecting that the prices will converge eventually. This strategy can be risky because even if the analysis is correct, prices can remain divergent for a long time, leading to potential losses.

3. Covered Interest Arbitrage

Covered interest arbitrage is a strategy that takes advantage of the difference in interest rates between two countries. It involves borrowing in a low-interest-rate currency, converting the borrowed amount into a high-interest-rate currency, and investing it in risk-free assets in the high-interest-rate currency country.

To mitigate exchange rate risk, traders typically use a forward contract to sell the future amount they will receive from the investment at the current forward rate. If the forward rate is favorably set relative to the spot rate, the trader can lock in a risk-free profit.

Covered interest arbitrage helps ensure that exchange rates and interest rates are in equilibrium. If they are not, traders can profit from the discrepancy until their actions drive the market back to equilibrium.

In Conclusion

Arbitrage strategies offer the potential for risk-free profit by exploiting price differences in different markets or different forms of an asset within a market. However, they require significant resources, sophisticated trading systems, and in-depth knowledge and experience in the markets.

Arbitrage strategies are commonly employed by hedge funds and other institutional traders rather than individual investors due to the complexity, speed, and resources required. However, the principles of arbitrage can still be useful for individual investors to understand as they reflect fundamental concepts about market pricing, risk, and return.
