CAPM equation
E(Rj) = rf + b[E(Rm) - rf]
0.14 = rf + 1.5(0.12-rf)
0.14 = rf + 0.18 - 1.5rf
-0.04 = rf - 1.5rf
-0.04 = (1-1.5)rf
-0.04 = -0.5rf
rf = 0.08
rf = 8%
Expected return= risk free rate + Risk premium = 11 rate of return on stock= Riskfree rate + beta x( expected market return- risk free rate)
The CAPM relates the expected return on a security to that of the overall market portfolio. A highly volatile security will have a high covariance with the market portfolio. Since beta equals the covariance of the security with the market portfolio divided by the variance of the market portfolio, the result is a high value of beta. When this high value of beta is plugged into the CAPM formula, all else not changed, the required return on the security (ra) is going to increase, implying investors require a higher return to hold a highly volatile security. t
It is discussed in efficient market hypothesis, meaning that you can not beat the market. Capital market line is drawn as a tangent on the curve representing both risky and non risky portfolio. At the point where tangent is drawn represents a model portfolio akin to market. All portfolio above this point has a higher risk reward ratio.

As a well-informed investor, you naturally want to know the expected return of your portfolio—its anticipated performance and the overall profit or loss it's racking up. Expected return is just that: expected. It is not guaranteed, as it is based on historical returns and used to generate expectations, but it is not a prediction. The expected return of a portfolio will depend on the expected returns of the individual securities within the portfolio on a weighted-average basis. A well-diversified portfolio will therefore need to take into account the expected returns of several assets. KEY TAKEAWAYS To calculate a portfolio's expected return, an investor needs to calculate the expected return of each of its holdings, as well as the overall weight of each holding. The basic expected return formula involves multiplying each asset's weight in the portfolio by its expected return, then adding all those figures together. In other words, a portfolio's expected return is the weighted average of its individual components' returns. The expected return is usually based on historical data and is therefore not guaranteed. The standard deviation or riskiness of a portfolio is not as straightforward of a calculation as its expected return. How to Calculate Expected Return To calculate the expected return of a portfolio, the investor needs to know the expected return of each of the securities in their portfolio as well as the overall weight of each security in the portfolio. That means the investor needs to add up the weighted averages of each security's anticipated rates of return (RoR). An investor bases the estimates of the expected return of a security on the assumption that what has been proven true in the past will continue to be proven true in the future. The investor does not use a structural view of the market to calculate the expected return. Instead, they find the weight of each security in the portfolio by taking the value of each of the securities and dividing it by the total value of the security. Once the expected return of each security is known and the weight of each security has been calculated, an investor simply multiplies the expected return of each security by the weight of the same security and adds up the product of each security. Formula for Expected Return Let's say your portfolio contains three securities. The equation for its expected return is as follows: Ep = w1E1 + w2E2 + w3E3 where: wn refers to the portfolio weight of each asset and En its expected return.
Yes. That's what it means. The "beta of 2" is a comparison to the market portfolio. The volatility measure is usually annualized standard deviation and the "market portfolio" is commonly the S&P 500 Index, but should be a broad index that is similar to the securities in the portfolio. The market portfolio used for a portfolio of international securities could be the MSCI EAFE Index, for example.
Generics' share of the prescription drug market was expected to increase from 22 percent in 1985 to more than 66 percent by the turn of the century.
In the world of finance: BETA is a measure of the volatility, or systematic risk, of a security or a portfolio in comparison to the market as a whole. Beta is used in the capital asset pricing model (CAPM), a model that calculates the expected return of an asset based on its beta and expected market returns.
Like the best portfolio theory for today's market is based on the Dynamic Market Environment theory.
The CAPM relates the expected return on a security to that of the overall market portfolio. A highly volatile security will have a high covariance with the market portfolio. Since beta equals the covariance of the security with the market portfolio divided by the variance of the market portfolio, the result is a high value of beta. When this high value of beta is plugged into the CAPM formula, all else not changed, the required return on the security (ra) is going to increase, implying investors require a higher return to hold a highly volatile security. t
