Introduction to International CAPM

Investing in any asset has risks that can be minimized by using financial tools to determine 澳洲幸运5开奖号码历史查询:expected returns. The 澳洲幸运5开奖号码历史查询:capital asset pricing model (CAPM) is one of these tools. This model calculates the 澳洲幸运5开奖号码历史查询: required rate of return for an asset using the expected return on both the market and a 澳洲幸运5开奖号码历史查询:risk-free asset, and the asset's correlation or sens🐼itivity 🐈to the market.

Some of the problems inherent in the model are its assumptions, which include: no 澳洲幸运5开奖号码历史查询:transaction costs, no taxes, investors who can borrow and lend at the risk-free rate and investors who are rational and 澳洲幸运5开奖号码历史查询:risk averse. Obviously these as🍸sumptions are not fully applicable to real-world investing. Despite this, CAPM is useful as one of several tools in estimating the return expected on an ൩investment. 

The unrealistic assumptions of CAPM have led to the creation of several expanded models that include additional factors and the relaxing of several assumptions used in CAPM. 澳洲幸运5开奖号码历史查询:International CAPM (ICAPM) uses the same inputs as the CAPM but also takes into account other variables that influence the 澳洲幸运5开奖号码历史查询:return on assets on a global basis. As a result, 澳洲幸运5开奖号码历史查询:ICAPM is far more useful than CAPM in practice. However, despite𝓡 relaxing some assumptions, ICAPM does have limitations that ꦓimpact its practicality. 

Understanding ICAPM Calculations

Since ICAPM introduces additional variables or factors to the CAPM model, investors first need to understand CAPM's calculations. CAPM simply states investors want to be compensated for:

  1. The 澳洲幸运5开奖号码历史查询:time value of money, which they expect to be more than the risk-free rate and
  2. Taking 澳洲幸运5开奖号码历史查询:market risk so they require a premium over the return of the market, less the risk-free rate, times the correlation with the market.

ICAPM expands on CAPM by further saying that in addition to getting compensated for the time value of money and the premium for taking market risk, investors need to be paid for 澳洲幸运5开奖号码历史查询:direct and indirect exposure to foreign 🐓currency. ICAPM allows investors to add currency effects to CAPM 𒊎to account for the sensitivity to changes in foreign💮 currency when investors hold an asset. This sensitivity accounts for changes in a currency that directly and indirectly affects profitability and, thus, returns. 

For example, if a company domiciled in the United States buys parts from China and the U.S. dollar strengthens relative the yuan, then the costs of those imports goes down. This indirect currency exposure impacts the profitability of a company and the returns generated by the investment. To determine these effects, investors need to calculate the difference between the expected future spot exchange rate and the 澳洲幸运5开奖号码历史查询:forward rate and divide that difference by today's 澳洲幸运5开奖号码历史查询:spot rate, the result of🌸 which is the foreign currency risk premium (FCRP). Then, mu♋ltiply that by the sensitivity of the domestic currency returns to changes in foreign currencies. ICAPM provides investors with a way of calculating expected returns in local currency terms by accounting for variables as stated below:

 Expected Return = RFR + β ( R m R f ) + β ( FCRP ) where: RFR = Domestic risk-free rate β = Beta R m = Expected return of market R f = Risk-free rate R m R f = Premium for global market risk measured in local currency FCRP = Foreign currency risk premium \begin{aligned} &\text{Expected Return} = \text{RFR} + \beta ( \text{R}_m -\text{R}_f ) + \beta ( \text{FCRP} ) \\ &\textbf{where:}\\ &\text{RFR} = \text{Domestic risk-free rate} \\ &\beta = \text{Beta} \\ &\text{R}_m = \text{Expected return of market} \\ &\text{R}_f = \text{Risk-free rate} \\ &\text{R}_m - \text{R}_f = \text{Premium for global market risk measured} \\ &\text{in local currency} \\ &\text{FCRP} = \text{Foreign currency risk premium} \\ \end{aligned} Expected Return=RFR+β(RmRf)+β(FCRP)where:RFR=Domestic risk-free rateβ=BetaRm=Expected return of marketRf=Risk-free rateRmRf=Premium for global market🅠 risk measuredin local currencyFCRP=Foreign currency risk premium

Assumptions

While ICAPM improves upon the unrealistic assumptions of CAPM, several assumptions are still required for the theoretical model to be valid. The most important assumption is that international 澳洲幸运5开奖号码历史查询:capital markets are integrated. If this assumption fails and international markets are segmented, then there will be pricing discrepancies among assets with similar 澳洲幸运5开奖号码历史查询:risk profiles but💛 in different currencies. As a result, segmented markets will cause investors to make higher allocations to specific assets in specific countries, resulting in inefficient asset pricing. ICAPM also assumes unlimited lending and borrowing at the risk-free rate.

Practical Uses

ICAPM's usefulness in stock select🍸ion and portfo🏅lio management is only as good as understanding the assump🎀tions as stated above. Despite these limitations, portfolio selection can be influenced by the model. Understanding the impact of currency movements on a particular company's operations and profits will help investors choose among two assets with similar characteristics in different countries. 

For example, if an investor in the U.S. wants to calculate the expected return from holding asset A and compare that to the expected return from holding asset B, he needs to determine the inputs for the last two components of the model, which are to determine the direct currency impact and the indirect currency impact. The first two variables in the equation will be the same for both assets. Therefore, the practical usefulness of the ICAPM is in understanding how one currency affects a company in the foreign country and how translating it to the investor's local currency will impact the return on the asset.

For example: An investor is deciding to invest in one of the following a𓆉⭕ssets:  

  • Company A: Japanese company that derives all of its profits and input costs in yen
  • Company B: Japanese company that derives all its profits in U.S. dollars but has input costs in yen

Both assets have similar betas, or sensitivity to changes in world 澳洲幸运5开奖号码历史查询:market portfolio. In a 澳洲幸运5开奖号码历史查询:macroeconomic environment where the U.S. dollar is weakening relative to the yen, an investor will determine that the profits for company B would decline, as it would cost more U.S. dollars to buy the products. As such, the req👍uired return would increase for company B, rel🍎ative to company A, to offset the additional currency risk. 

The Bottom Line

ICAPM is one of several models used to determine the required return on an asset. Used in conjunction with other financial tools, it can assist investors in selecting assets that will 澳洲幸运5开奖号码历史查询:meet their required rate of return. ICAPM, like CAPM, makes several assumptions, including that global markets are integrated and efficient. If this assumption fails, then stock selection is critical; allocating more resources toward investments in countries that have a currency advantage should result in alpha. Currency adv🐎antages tend to disappear quickly as exploited market inefficiencies close, but the fact that t🐲hese inefficiencies occur argues that active portfolio management is key to providing superior returns over the market portfolio.
