Uses and Iimitations of the CAPM
Introduction
Graham and Harvey surveyed the CFOs of 392 U.S. firms and found that when estimating the capital of assets,73.5% of respondents use the CAPM.( Graham, J. R., and C. R. Harvey,2001) It is a model which uses simple formula to evaluate asset pricing and investor behavior. This model is absolutely the method with most investors used, but many financial experts raise an objection to the veracity of this method in the recent years. Later in the main body of the essay will discuss these questions. In the first part of the essay will introduce the CAPM and the main factor of this method. Secondly, is the discussion of the uses and limits of the CAPM while evaluating the potential investment of a firm 's

(Hillier, Ross, and Westerfield, 2010)And they use CAPM to compare stocks ' expected return estimated by CAPM to buy the cheapest stock. Beta coefficient is the most difficult estimated value in CAPM and this is the most important value in CAPM which used to measure the market risk of an asset. Beta is 1 when the percent of change of share price and market price are the same. When the Beta is larger than 1. For example, beta is 2.0 means when the market price increase by 10% then the share price will increase 20% and vice versa. Therefore, investors can invest their money in those stocks with lower beta when the market price decrease and invest in stocks with beta larger than 1 when the market price increase. This model is widely used in Investment. Beta is calculated with historical data and the length of data is also very important to the variance of beta. The longer the time the more stable the variance is. However, if the term is too long, the change of business operation, market, technology, competitive force and the feature of the market will affect the value of beta. Besides, many popular index funds give investors a chance to hold diversification at low cost.
Limitation of CAPM while estimating the potential investment of a firm 's share from investors ' point of view. The assumptions of CAPM is the limitation of this
For example if ABC Goods had 1 million shares and they all cost R10 their market cap would cost R10million that is basically the cost of the company and how much you can offer to buy the company and the shareholders should be okay with it and it can also refer to the total amount of the stock exchange
The estimates of cost of capital for equity 6.14% are making by using the capital asset pricing model (CAPM) to generate forecast of DDM and RIM. This method is defined by the sum of risk free rate plus beta that multiplied with a risk premium. Particularly, the beta, which is a quantitative measure of the volatility of company stock relative to the unstable of the overall market, found in JB HI-FI case at 0.56 (JB HI-FI financial statement 2016). It
Fama and French findings shocked the modern portfolio theory and their study was nick named "Beta is Dead". With respect to CAPM they found that stocks with high betas did not have consistently higher returns than low-beta stocks. Furthermore, Fama and French concluded that a high book value to market value was the most important variable related to predicting high stock returns on small cap stocks. These findings were published in a 1992 paper titled "The Cross-Section of Expected Stock Returns".
Cost of Equity (Ce) was calculated based on the CAPM formula. 30-year T-bond was used as a long-term risk-free security to get the risk-free rate, since Marriott used the cost of long-term debt for its lodging cost-of-capital calculations. The market premium 8.47 was the arithmetic-average spread between the S&P 500 returns and the short-term US T-bills between 1926-1987. This market premium is consistent with the current academic suggestions and it was used in all calculations of this exercise.
Over the previous five years, the return of the ProIndex fund have outperformed the S&P 500 index, as the 5-year-return is nearly 3 times than the benchmark and the annualised return is nearly 2 times than the benchmark. It means ProIndex fund has a significant increase in value within that period. However, the ProIndex Fund has a higher standard deviation which means it is more risk than the S&P 500 index. Especially for the annualised standard deviation, it is approximately 10% higher than the benchmark. The correlation coefficient between the ProIndex and benchmark is about 0.65 which means both two variables are positive changing consistently, but there are still some other factors which have impacts on the relationship between two variables as the correlation is less than 1. Furthermore, the higher beta, 1.0132, which is more than 1 and it may be one of the reasons for high risk as well since it is more sensitive to the market change. It means that the ProIndex fund would increase by 1.0132% if the market increased by 1%.
The advice I would give to others who are doing simulation is trying to understand other functional areas in addition to your main functional one. I realized that after learning the other functional areas, I make more contribution to the team and help get the team in the right direction. Of course, each member first needs to concentrate and make good decision in their own functional area. However, understand each area and their interaction would provide the whole picture and guide decisions to the right direction. The other advice is each member needs to spend considerable of time to prepare such as watching Capsim videos for the simulation so that they can avoid mistakes, especially in the early rounds.
The lives of all individuals are impacted by social policies that have been created and written in the past and this impact will continue as historical social policies are updated and with each future social policies that is created and written. The impact of social policy is significant because, “Although social policy may address individual needs, it also typically benefits the host society” (Chapin, 2014, p.2). In other words, each social policy does not directly impact each individual in society, but overall social policies impact the entire society in some form or another. “Social policies are the rules, laws, and regulations that govern the benefits and services provided by the government and private organizations to assist people in
The following essay will expand on the usefulness and flaws of CAPM and other asset evaluation frameworks and in the end showing that despite all the evidence against CAPM it is still a useful model for determining asset investments.
I am not going to lie this class was my hardest it felt like I didn’t know what was going on at all time. It not like I wasn’t learning anything in there is just that I didn’t really get the class at all. Every time went on Capsim to do work I never get anything do because I didn’t know what I was doing. Is not like I didn’t like the class the class I just us doing the Capsim online was hard for some people because they didn’t know what to do. Next semester I think the class should be thought like microeconomic because more people we will it better. Another idea I was thinking was we could do a field trip to some business meetings even though I know students in college don’t do feel trip. The feel trip will give us an ideal of what a real
There is a sense of complexity today that has led many to believe the individual investor has little chance of competing with professional brokers and investment firms. However, Malkiel states this is a major misconception as he explains in his book “A Random Walk Down Wall Street”. What does a random walk mean? The random walk means in terms of the stock market that, “short term changes in stock prices cannot be predicted”. So how does a rational investor determine which stocks to purchase to maximize returns? Chapter 1 begins by defining and determining the difference in investing and speculating. Investing defined by Malkiel is the method of “purchasing assets to gain profit in the form of reasonably predictable income or appreciation over the long term”. Speculating in a sense is predicting, but without sufficient data to support any kind of conclusion. What is investing? Investing in its simplest form is the expectation to receive greater value in the future than you have today by saving income rather than spending. For example a savings account will earn a particular interest rate as will a corporate bond. Investment returns therefore depend on the allocation of funds and future events. Traditionally there have been two approaches used by the investment community to determine asset valuation: “the firm-foundation theory” and the “castle in the air theory”. The firm foundation theory argues that each investment instrument has something called intrinsic value, which can be determined analyzing securities present conditions and future growth. The basis of this theory is to buy securities when they are temporarily undervalued and sell them when they are temporarily overvalued in comparison to there intrinsic value One of the main variables used in this theory is dividend income. A stocks intrinsic value is said to be “equal to the present value of all its future dividends”. This is done using a method called discounting. Another variable to consider is the growth rate of the dividends. The greater the growth rate the more valuable the stock. However it is difficult to determine how long growth rates will last. Other factors are risk and interest rates, which will be discussed later. Warren Buffet, the great investor of our time, used this technique in making his fortune.
The final model used to compute the cost of capital was the earning capitalization model. The problem with this model is that it does not take into consideration the growth of the company. Therefore we chose to reject this calculation. The earnings capitalization model calculations were found this way:
The efficient market hypothesis has been one of the main topics of academic finance research. The efficient market hypotheses also know as the joint hypothesis problem, asserts that financial markets lack solid hard information in making decisions. Efficient market hypothesis claims it is impossible to beat the market because stock market efficiency causes existing share prices to always incorporate and reflect all relevant information . According to efficient market hypothesis stocks always trade at their fair value on stock exchanges, making it impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices. As such, it should be impossible to outperform the overall market through expert stock selection or market timing, and that the only way an investor can possibly obtain higher returns is by purchasing riskier investments . In reality once cannot always achieve returns in excess of average market return on a risk-adjusted basis. They have been numerous arguments against the efficient market hypothesis. Some researches point out the fact financial theories are subjective, in other words they are ideas that try to explain how markets work and behave.
The capital structure of a firm is the way in which it decides to finance its operations from various funds, comprising debt, such as bonds and outstanding loans, and equity, including stock and retained earnings. In the long term, firms seek to find the optimal debt-equity ratio. This essay will explore the advantages and disadvantages of different capital structure mixes, and consider whether this has any relevance to firm value in theory and in reality.
Stock market prediction is the method of predicting the price of a company’s stock. It is believed that stock price is lead by random walk hypothesis. Random walk hypothesis states that stock market price matures randomly and hence can’t be predicted. Pesaran (2003) states that it is often argued that if stock markets are efficient then it should not be possible to predict stock returns. In fact, it is easily seen that stock market returns will be non-predictable only if market efficiency is combined with risk neutrality. On the other hand it is also been concluded that using variance ratio tests long horizon stock market returns can be predicted....
The Modern portfolio theory {MPT}, "proposes how rational investors will use diversification to optimize their portfolios, and how an asset should be priced given its risk relative to the market as a whole. The basic concepts of the theory are the efficient frontier, Capital Asset Pricing Model and beta coefficient, the Capital Market Line and the Securities Market Line. MPT models the return of an asset as a random variable and a portfolio as a weighted combination of assets; the return of a portfolio is thus also a random variable and consequently has an expected value and a variance.
