Case Study of Cost of Capital at Ameritrade 1-a How can the CAPM be used to estimate the cost of capital for a real business investment decision? CAPM results can be compared to the best expected rate of return that investor can possibly earn in other investments with similar risks, which is the cost of capital. Under the CAPM, the market portfolio is a well-diversified, efficient portfolio representing the non-diversifiable risk in the economy. Therefore, investments have similar risk if they have the same sensitivity to market risk, as measured by their beta with the market portfolio. So, the cost of capital of any investment opportunity equals the expected return of available investments with the same beta. This estimate is …show more content…
Then we noticed that in exhibit 4, the period of historical data is from 1992-1996. However , the stock of Waterhouse Investor Srvcs only last to Sep 1996, in order to compare the data in the same time horizon, we select the period of 5 years, started from Sep 1991 to Sep 1996. We use ri=(Pt-Pt-1+Dt)/Pt-1 to calculate the monthly return rate of stocks. When the stock split, ri= (x/y*Pt-Pt-1+x/y*Dt)/Pt-1 We chose VW portfolio of NYSE, AMEX, and NASDAQ rather than EW of NYSE, AMEX, and NASDAQ because the value-weight portfolio can reflect the real market situation better. We use the equation ri=(Pt-Pt-1+Dt)/Pt-1 to calculate the monthly return of stock of Charles Schwab Corp, Quick & Reilly Group and Waterhouse Investor Srvcs. Then we have two methods to calculate the Beta of Equity for each company. The first method is using equation COV(Ri,Rm)/Var(Rm) to get the Beta. Then we use BAsset=E/(E+D)*BE+D/(E+D)*BD to calculate the Beta of Asset. We assume that the debt of these companies is risk free, because debt represents only a small fraction of the firm’s value. Here are the answers: | COV (Ri,Rm) | Var Rm | Beta | D/V | E/V | Asset Beta | Charles Schwab | 0.001899719 | 0.000746187 | 2.545901945 | 0.08 | 0.92 | 2.342229789 | Quick & Reilly | 0.001902394 | 0.000746187 | 2.549486932 | 0.00 | 1 | 2.549486932 | Waterhouse Investor Services | 0.002690693 | 0.000746187 | 3.605922579 | 0.38 |
The table below shows the equity betas for the firms presented in the case (using Jan-92 to Dec-96 equal weight NYSE/AMEX/NASDAQ as market portfolio):
Here we choose VW NYSE, AMEX, and NASDAQ data as market returns, because it’s value weighted and more reliable. The results show CSC’s equity beta = 2.27, QRG’s equity beta = 1.79.
Given these approximations, the CAPM model would total the risk-free rate and the market risk premium times beta to arrive at a cost of equity of 9.68%, which reflects the investors’ expected return from investing in shares of the company.
Cost of capital is what it will cost the firm, on the margin, today, to secure its financial resources for further growth.
Cost of Equity = Risk free rate + (Market return – risk free rate) X beta
Risk free rate + Equity Beta * (Expected return on market - Risk free rate)
* We assume the cost of capital to be a stated annual rate to facilitate calculations;
Since the company is newly listed in stock market, no sufficient historical data for the calculation of beta, so we selected the comparable companies Charles Schwab Corp (Discount Brokerage), Quick & Reilly Group (Discount Brokerage) and Waterhouse Investor Srvcs (Discount Brokerage). Because the operating business scope and the brokerage revenue percentage to total revenue for these companies are similar to the Ameritrade, we just use these companies’ historical data for the calculation of Ameritrade’s beta. *Note: Although E*Trade (Discount Brokerage) has the similar business scope with the Ameritrade, we excluded this company since the company strategy is not to be a discount brokerage.
In theory, CAPM is an asset pricing model which states that assets are priced commensurate with a trade-off between undiversifiable risk and expectations of return (Dempsey, 2013). It is based on certain assumptions like Modern Portfolio Theory, Arbitrage Pricing Theory (APT) and Efficient Market Hypothesis (EMH) where investors are assumed rational under the Market Rationality.
Beta is a measure of the market risk of a security or a portfolio in comparison to the market as a whole. It is used in the Capital assets pricing model (CAPM), which calculates the expected return, and assets based on its beta and expected market returns. The market beta is set at 1.00 and every stock is calculated by value line based on past stock price volatility. A beta of less than 1 indicates that the security will be less volatile than the market whereas a beta greater than 1 indicates that the security price will be more volatile than the market.
The CAPM model was developed by Sharpe (1964) to explain how capital markets set share prices. (Pike and Neale) In result of research by Sharpe (1964), Litner (1965) and Black (1972) the Capital Asset Pricing Model (CAPM) states “the relationship between beta (measure of volatility on portfolios/assets) and expected returns is linear, exact, and has a slope equal to the expectation of the market portfolio excess return”. CAPM makes the assumption that markets are efficient therefore suggesting that operators within the market have rational expectations, this assumption leads us to the first weakness of CAPM (Vernimmen, 2011). However, when estimating the cost of capital, CAPM is seen to be preferred compared to other asset pricing models simply due to its simplicity. In a survey conducted by the Association for Financial Professionals (2011) it was found that when estimating the cost of capital 87% of all firms and 91% of publicly traded firms used CAPM.
This paper examines key elements of a cost of capital policy to facilitate objective management and allocation of corporate funds. In order for a company to make long-term investments to grow, whether that is new equipment, new products or other assets, managers must be aware of the cost of acquiring any of these assets. The obvious objective for these managers is to earn more than the cost of capital and in doing so will increase their company’s market value. If they fail to adequately estimate their cost of capital and their long-term investments fall beneath the cost of capital, their company’s market value will decline as a result. This ongoing battle of managing and calculating the cost of capital and
Capital asset pricing model was developed by Sharpe (1964) and furthered through the works of Lintner (1965), Mossin (1966), Treynor (1965) and Black (1972). This model calculates expected/required rate of return for any risky financial asset. Capital Asset Pricing Model formula is shown in figure 1.1. Essentially, this represents investors need to be compensated for their time value of money and risk. Beta is measure of volatility and will be further examined in later stages of this essay. For example, if our particular company has a high standard deviation of the rate of return, an investment in the company might appear
So, E (ri) is the cost of equity and the premium an investor should expect for taking on the additional
We use the Capital Asset Pricing Model (CAPM) to determine the cost of equity. As
