Critically discuss the uses and limitations of the CAPM
Introduction
Capital Asset Pricing Model (CAPM) was developed in 1964 based on Modern Portfolio Theory. CAMP widely used in investment decisions and financial areas of the company. The main research of CAMP are the relationship between expected rate of return and risk assets in the stock market, as well as how the equilibrium price formation. In terms of the valuation of assets, CAPM primarily used to determine whether the securities market be mispricing. Capital Asset Pricing Model measure risk by non-diversified variance, it linked risk and expected return, any non-diversified risk assets can be described by the value of β, then calculate the expected rate of return. Rate of return required by investors is equals to the discount rate. The limitation of CAPM are: CAPM assumptions inconsistent with the actual; CAPM Should apply only to capital assets, human assets may not be traded; Estimated β coefficient represents the past of variation, but investors are concerned about the security volatility of future price; In the actual situation, the risk-free asset and the market portfolio may not exist.
Main Body
The advantage of CAPM is that it provide a clear and intuitively explicit forecast in regard to how to measure risk and the connection between risk and expected return(Fama & French , 2004).Accordance to the provisions of CAPM, Beta coefficient is used to measure an asset systemic risk, it is used to measure the
Capital asset pricing model or CAPM is a financial model that measures the risk premium inherent in equity investments like common stocks while Discounted Cash Flow or DCF compares the cost of an investment with the present value of future cash flows generated by the investment with the mindset being that if the cash flow is positive, then the investment is good. Generally speaking, CAPM is a model that describes the relationship between risk and expected return and DCF is a valuation method used to estimate the attractiveness of an investment opportunity. So what are the differences, advantages and disadvantages of each one? How
This essay will highlight the use of Capital asset pricing model ( CAPM ) to be considered as a pricing theory model for assets . CAPM model helps investors to analyse the risk and what expectation to keep from an investment (Banz , 1981) . There are two types of risk
In order to test the validity of the CAPM, we have applied the two-step testing procedure for asset pricing model as proposed by Fama and Macbeth (1973) in their seminal paper.
The analysis of this paper will derive the validity of the Fama and French (FF) model and the efficiency of the Capital Asset Pricing Model (CAPM). The comparison of the Fama and French Model and CAPM (Sharpe, 1964 & Lintner, 1965) uses real time data of stock market to practise its efficacy. The implication of the function in realistic conditions would justify the utility of the CAPM theory. The theory suggests that the expected return demanded by investors on a risky asset depends on the risk-free rate of interest, the expected return on the market portfolio, the variance of the return on the market portfolio, and
Eugene Fama from the University of Chicago and Kenneth R. French from the Yale School of Management's were done a research on examining the validity of capital asset pricing model (CAPM). It was published in 1992; and well-known as The Fama-French three factors model (TFM).
Capital Asset Pricing Model(CAPM) is introduced by Sharpe, Lintner, and Mossin and this model is derived by Markowitz mean-variance model theory. CAPM is applied to investment decision problems. CAPM is also about the understanding of an assets return and also the diversify of risk.
The main message of the Capital Asset Pricing Model (CAPM) attempts to find value in financial assets by connecting an asset's return and its risk. It is a simple analytical tool used to find a rather straightforward and simple question: How much risk is contained in this investment?
This summary provides a brief overview of Capital Asset Pricing Model (CAPM) as an alternative method for estimating expected returns. This paper also discusses the positive and negative effects of CAPM along with the risks of Beta and why this model has its share of drawbacks and critics in the marketplace. The first section will cover the basics of CAPM including its flaws and rewards. Next, the risks of beta and the strengths and weaknesses are discussed in conjunction with its relevance to CAPM and why it’s important to investors who are willing to take greater risks. Finally, an application is provided to show how beta affects CAPM from a financial manager’s perspective.
CAPM is a highly acclaimed theory of risk and return for securities in a competitive capital market. The path breaking theory won Sharpe, Markowitz, and Miller the Nobel Memorial Prize in Economics in 1990. CAPM establishes the Beta coefficient as a measure of the systematic risk of an asset. The systematic risk is also known as market risk. This risk cannot be eliminated. This systematic risk is uncontrollable. The unsystematic risks include the risk that influences a single company or a small group of company and the same is controllable and can be mitigated through diversification.

Over the past few decades, economists were continually developing a variety of asset pricing models. The first and the most important model is called Capital Assets Pricing Model, which was developed by William Sharpe, John Lintner and Jack Treynor (1964). It is based on the theory of composition and capitalization, which discussed the expected return and the relationship between risky assets in stock market. And now, Capital Asset Pricing Models becomes the pillar of multiple asset pricing models, and widely use in investment.

This essay will illustrate the practicability of the capital asset pricing model (the CAPM). Before 30 years ago, the capital asset pricing model was a significant development. This theoretical model has been used in many large companies. Yet, many economists argue that this model has its own drawbacks. In 1992, Fama and French said that the application of CAPM could be useless which against empirical tests of the CAPM. For instance, the CAPM was seen as an obsolete theory because of the limitation of its assumptions. Main assumptions can be categorized into six aspects. First, the CAPM assumption was built on that the capital market is always in equilibrium. This assumption is difficult to achieve in the real world. Second, there are a numeral of investors who hold the same period of their asset in the market and no considering of the outcome after the investment plan. However, there are too many investors in the market, it is impossible that their time of holding the asset could be exactly the same. Therefore, the second assumption is also unachievable. The third hypothesis is that investors have unrestricted of borrowing and lending at fixed risk-free rate which is also very difficult. The fourth of assumption is assumed that there are no transaction costs and taxes. But in fact, these factors are all existed in the real market. Then, the fifth and sixth assumption shows all investors have the same expectation on their investment portfolio. Obviously, these two
The evidence gained from examination done by Nimal and Fernando (2013) concerning Tokyo Stock Exchange (TSE) and the Colombo Stock Exchange (CSE) confirmed not only that beta is a useful tool in expanding deviations in market premium, but also that there is a relation between return and beta. However, the previous research done in the Japanese market by Yonezawa and Hin, (1992) did not confirm the validity of the CAPM. In their research, they checked monthly returns from January 1952 to December 1986 and concluded that limited diversification was the main cause of CAPM failure.
CAPM is a hugely popular model used in some capacity by virtually all major firms. The CAPM formula basically says that the expected rate of return on an asset is proportional to how much risk it contributes to the market portfolio. CAPM is represented by the formula: ri = rf + β(rm − rf), where ri is the required rate of return, rf is the risk free rate and β is the asset’s systematic risk. It says that the expected return of a security or a portfolio equals the rate on a risk-free security plus a risk premium. This figure essentially represents the cost of capital for a firm. It is an extremely popular model due to its simplicity and the ease with which it can be applied. There is however an increasing body of thought that the CAPM approach is in fact outdated and not a reliable model with which to evaluate cost of capital. Some of the chief arguments against CAPM are that it only holds under very unrealistic assumptions and another huge issue with CAPM is what is now known as the size effect.
