#CAPITAL ASSET PRICING MODEL CAPM PLUS#

Two plus two will not make it four in the aggregation of risks, as shown by famous author Markowitz. In considering the portfolio, not only returns are to be considered as in the case of single investments but their risks also. Using the CAPM (Capital Asset Pricing Model)model, please compute the expected return of a stock where the risk-free Rate of return is 5%, the beta of the stock is 0.In valuation of investments, one has to consider his assets in the portfolio as a part of his total investments.

It creates a theoretical relationship between risk and the rate of return from a portfolio.

CAPM (Capital Asset Pricing Model) considers systematic risk, as the unsystematic risk can be diversified.

If the Shares prices fall and outweigh the dividend yield, a stock market can provide a negative rather than a positive return.Īdvantages of CAPM (Capital Asset Pricing Model)

Market Return – The stock market return can be calculated as the sum of the average capital gain and the average dividend yield.

So the expected return might also differ.

Beta – The value of beta changes over time.

Risk-free rate – The yield on the government bond is used as a risk-free rate of return, but it changes on a daily basis according to the economic circumstances.

In CAPM (Capital Asset Pricing Model), values must be assigned for the risk-free rate of return, risk premium, and beta.

Transaction cost in the financial market is assumed to be low cost, and the investors can buy and sell the assets in any number at a risk-free rate of return.

While making the investment decision, investors consider only a single period horizon, not multiple period horizons.

So if a portfolio has a higher risk, the investors expect a higher return. They would want to invest in a portfolio that has low risk.

For example, if the investor gets a return of 20% and the risk-free rate is 7%, then the risk premium is 13%.Īssumptions for the CAPM (Capital Asset Pricing Model) Model It is the return that an investor expects above the risk-free rate of return to compensate for the risk of volatility that a person is taking by investing in the stock market. The risk premium is calculated using the formula stock market return minus Risk-free rate of return.

For example, if the company security has a beta of 1.5 and the stock market moves up by 10%, then the security moves up by 15 % and vice versa. If the beta of company security is more than 1, the security has high volatility.

For example, a company has a beta of 0.5 this means that if the market has an upward movement of 10%, the company will have an upward movement of 5% and vice versa. If a security’s beta is less than 1, it means that the security is less volatile in comparison to the market.If a security’s beta is equal to 1, if the market moves upward by 10%, the stock having beta equal to 1 will also increase by 10% and vice versa.One can measure this risk with a beta.īeta measures the volatility of a security in comparison with the market as a whole. For example, interest rate rises suddenly or fluctuations in the trading price of a security impact the entire market. It occurs due to external factors that affect an organization and is uncontrollable in nature. Systematic risk is a risk that is not diversifiable. For example, workers have gone on a strike, customers’ commitments are not fulfilled, the regulatory framework conflicts with government policy, etc. This risk arises due to the internal factors prevailing in an organization. Unsystematic risk is a diversifiable risk. Risk can be classified as systematic risk and unsystematic risk.

As in this situation, the investors have to reinvest their future income, yield, or the final return of principal in lower-yielding securities. Reinvestment risk emerges for the investor when the yield of the bonds falls. Default risk occurs when companies or individuals fail to repay their debt obligations. For a security to be risk-free, it should not have default and reinvestment risks. Government bonds are known as risk-free securities. Risk-free is the minimum rate of return that an investor will receive if they invest in risk-free security. Now let’s understand these key terminologies of the formula: Risk-Free Rate Beta (Ba) = A measure of the variability of a company’s stock price in relation to the stock market overall.Risk premium ( R p) = the return that equity investors demand over a risk-free rate.Risk-free rate (rrf ) = the rate of return for a risk-free security.Cost of equity (Ke ) = the rate of return expected by shareholders.Cost of equity = Risk-free rate + Beta X Risk premium
