Triangular Arbitrage Meaning, Principles, Mechanics, Limitations


In comparison to the classical quick arbitrage transaction, such an operation can produce disastrous losses. Many exchanges and inter-dealer brokers allow multi legged trades (e.g. basis block trades on LIFFE). However, individual investors could also take advantage of arbitrage by investing in an arbitrage fund, a particular type of mutual fund. They can be a good choice for investors wanting to profit without taking on a lot of risks, but due to the nature of arbitrage trading, the actual returns can be unpredictable. Arbitrage, in principle, is a risk-less way of making a profit as transactions happen simultaneously and because there is no holding period. However, it isn’t as simple as it sounds – high transaction fees, price fluctuations, and the fact that traders must complete these transactions fast can eliminate already marginal profits.

  1. Traders still face execution risk, counterparty risk, and liquidity risk in trading.
  2. We have to determine the systematic factors by which portfolio returns are explained.
  3. In triangular arbitrage, traders convert one currency into another, then into a third currency, and finally back into the original currency, creating a triangle of currency transactions.
  4. Pure arbitrage is also possible in instances where foreign currency exchange rates lead to pricing discrepancies, however small.

These, transaction costs, taxes, and other costs provide an impediment to this kind of arbitrage. Similarly, arbitrage affects the difference in interest rates paid on government bonds issued by the various countries, given the expected depreciation in the currencies relative to each other (see interest rate parity). This curve can be used to view trends in market expectations of how interest rates will move in the future. In arbitrage-free pricing of a bond, a yield curve of similar zero-coupon bonds with different maturities is created. If the curve were to be created with Treasury securities of different maturities, they would be stripped of their coupon payments through bootstrapping. The yield of these zero-coupon bonds would then be plotted on a diagram with time on the x-axis and yield on the y-axis.

Triangular Arbitrage

The equation also includes an error term to account for features specific to that security, which cannot be explained by the broad factors. Importantly, APT is also based on a statistical model, which assumes that asset return can be described by a factor model. Here, each factor has a ‘beta’ attached to it, which indicates how sensitive the security is to that particular factor. Essentially, ‘beta’ shows the extent to which the returns on that security rise or fall for a specific change in that factor. What do the theories of an 18th century Scottish economist and philosopher have to do with the price of consumer goods, financial assets like stocks and bonds, and even how to use Airbnb to make money from a property you don’t own? There are many different arbitrage strategies that exist, some involving complex interrelationships between different assets or securities.

As arbitrageurs keep buying and selling the good, the price will eventually adjust to the point where there is no longer an arbitrage opportunity. Arbitrage is generally thought of as a risk-free investment strategy, but this is not always the case. While arbitrageurs aim to profit from price discrepancies, they also face the risk of losing money. Advances in automation and artificial intelligence (AI) technology are transforming the way arbitrage is performed, making it more efficient and profitable than ever before. This is facilitated by the ability of computers to process vast amounts of data at remarkable speeds, allowing them to spot inefficiencies in the market and exploit arbitrage opportunities before they’re evident to human traders.

By exploiting inefficiencies and correcting price disparities, arbitrageurs play a vital role in maintaining market balance, whether in the financial markets or in more unconventional areas like real estate and ticket scalping. This involves capitalizing on the price difference between a company’s stock before and after a merger, acquisition, or other significant corporate event. Traders aim to benefit from the price movement resulting from the event’s outcome. Arbitrageurs flock to financial markets because they’re flush with opportunities, and the results of their activities often benefit market participants. For example, arbitrage helps minimize slippage—the difference between the expected price of an asset and the actual price that a trade takes place—by reducing price disparities across markets. Price discrepancies across markets are generally minute in size, so arbitrage strategies are practical only for investors with substantial assets to invest in a single trade.

Doing merger arbitrage means you have to lock up your money for a longer period of time plus take on the risk that the merger doesn’t materialize, or you aren’t able to resell your shares at the value you’d aimed for. In conclusion, CSR and sustainability play a significant role in defining a firm’s systematic risk and therefore its position within the APT model. By contributing towards enhancing a firm’s reputation and lowering its risk of financial penalties, both CSR and sustainability can potentially decrease a firm’s beta and enhance its appeal to investors. As a result, firms are increasingly turning to these strategies to optimise their financial performance. When delving deeper into the practical application of Arbitrage Pricing Theory (APT), its substantial impact on financial markets and investment portfolios become clear.

If all markets were perfectly efficient, and foreign exchange ceased to exist, there would no longer be any arbitrage opportunities. But markets are seldom perfect, which gives arbitrage traders a wealth of opportunities to capitalize on pricing discrepancies. Pure, “textbook” arbitrage is considered low- (or no-) risk because it doesn’t involve additional capital; it’s merely buying in one market and selling in another. However, arbitrage in the real world usually entails large-volume trades as well as leveraged capital, timing variations, and other factors that increase risk. These inefficiencies create temporary discrepancies in exchange rates, which savvy traders can exploit to generate risk-free profits. An example of arbitrage is when somebody buys a stock on one exchange for ten dollars and immediately sells it on another exchange for eleven dollars.

In sum, arbitrage is vital for asset pricing and the balance of markets within the framework of Arbitrage Pricing Theory. It’s an underlying principle that ensures price consistency and market efficiency by exploiting price discrepancies. Furthermore, in an arbitrage-free market, all risk factors are encompassed in the prices of assets, making APT a highly effective asset pricing model. As traders exploit arbitrage opportunities, they indirectly contribute to the adjustment of asset prices. The act of buying low and selling high eventually leads to a balance, with the prices of identical or similar assets aligning across different markets.

The macroeconomic factors that have proven most reliable as price predictors include unexpected changes in inflation, gross national product (GNP), corporate bond spreads and shifts in the yield curve. Other commonly used factors are gross domestic product (GDP), commodities prices, market indices, and exchange rates. The arbitrage pricing theory was developed by the economist Stephen Ross in 1976, as an alternative to the capital asset pricing model (CAPM). Unlike the CAPM, which assume markets are perfectly efficient, APT assumes markets sometimes misprice securities, before the market eventually corrects and securities move back to fair value. Using APT, arbitrageurs hope to take advantage of any deviations from fair market value. Arbitrage is the act of buying something at a low price and then selling it at a higher price.

Factors Affecting Triangular Arbitrage

This also has the effect of regulating certain arbitrage activities, because if arbitrageurs were to exploit their positions unethically, they would be in violation of this legislation. In terms of assumptions, CAPM makes stronger assumptions including that investors have homogeneous expectations and hold the same market portfolio of risky assets. APT, however, allows for heterogeneity among investors and does not assume that all investors hold the same portfolio. principles of arbitrage With the evolution of technology and its rapid improvements, financial processes and transactions that were previously reserved for banks and financial institutions have become available to individuals and companies alike. Nowhere is the influence of advanced technology more evident in finance than in the area of arbitrage. The Combined Index Portfolio has the same betas to the systematic factors as the ABC Portfolio but a lower expected return.

In an ideal financial environment, comparable assets or securities should have similar prices, barring any discrepancies due to unique properties or characteristics. Differences in pricing and valuation can exist for similar assets in different markets. Understanding the contrast between APT and CAPM also provides insight into different investment strategies. On the other hand, Arbitrage Pricing Theory allows for the possibility of multiple risk factors influencing the returns. It does not merely focus on the beta (market risk), but it considers several unspecified systemic risk factors.

The principal risk, which is typically encountered on a routine basis, is classified as execution risk. This transpires when an aspect of the financial transaction does not materialize as anticipated. The former, counterparty risk, is characterized by the failure of the other participant in a substantial transaction, or a series of transactions, to fulfill their financial obligations. Liquidity risk, conversely, emerges when an entity is necessitated to allocate additional monetary resources as margin, but encounters a deficit in the required capital. Earning interest in this way is nowadays rarer, especially when both markets are aware of each other’s exchange rates and as markets try to bring any imbalances to an equal level.

For instance, companies that implement sustainable practices, such as reducing their carbon footprint, may dodge potential penalties from environmental regulations. Avoiding these penalties could result in decreased betas for these companies due to lower risk exposure. Consequently, they could provide lower expected returns, making them more appealing to risk-averse investors. The APT asserts that an asset’s expected return should equal the risk-free rate plus a risk premium. This risk premium compensates the investor for the asset’s sensitivity to each non-diversifiable risk factor.

However, there are other risks to consider, such as execution risk, technological risks, and market risks, which can impact profitability. Successful execution of triangular arbitrage relies on factors such as market liquidity, transaction costs, market volatility, and the speed of execution. The goal is to identify instances where the combined exchange rates of these three transactions result in a profit after accounting for transaction costs. Statistical arbitrage relies heavily on complex mathematical modelling, with an aim to profit from pricing inefficiencies identified through statistical analysis.
