Beta of portfolio containing stocks and risk free assets
What is the beta of a risk-free portfolio?
The Beta of a risk-free asset is zero because the risk-free asset’s covariance and the market are zero.
How do you find the beta of a risk-free asset?
Subtract the risk-free rate from the market (or index) rate of return. If the market or index rate of return is 8% and the risk-free rate is again 2%, the difference would be 6%. Divide the first difference above by the second difference above. This fraction is the beta figure, typically expressed as a decimal value.
What are the betas of the market portfolio and the risk-free asset?
Risk-free assets have a beta of 0 and the market portfolio has a beta of 1.
How do you find the beta of a stock portfolio?
Beta could be calculated by first dividing the security’s standard deviation of returns by the benchmark’s standard deviation of returns. The resulting value is multiplied by the correlation of the security’s returns and the benchmark’s returns.
Can a risky asset have a beta of zero?
Yes. It is possible, in theory, to construct a zero beta portfolio of risky assets whose return would be equal to the risk-free rate. It is also possible to have a negative beta; the return would be less than the risk-free rate.
What is the beta of a stock?
Beta is a way of measuring a stock’s volatility compared with the overall market’s volatility. The market as a whole has a beta of 1. Stocks with a value greater than 1 are more volatile than the market (meaning they will generally go up more than the market goes up, and go down more than the market goes down).

How do you calculate asset beta?
Unlevered beta (also called asset beta) represents the systematic risk of the assets of a company. It is the weighted average of equity beta and debt beta.
Formula.
| Unlevered Beta (βA) = | Equity Beta (βE) |
|---|---|
| 1 + (1 − t) × D/E |
How do you find the beta and alpha of a stock?
Calculation of alpha and beta in mutual funds
- Fund return = Risk free rate + Beta X (Benchmark return – risk free rate)
- Beta = (Fund return – Risk free rate) ÷ (Benchmark return – Risk free rate)
- Fund return = Risk free rate + Beta X (Benchmark return – risk free rate) + Alpha.
What is the portfolio beta of your portfolio?
The beta of a portfolio is the weighted sum of the individual asset betas, According to the proportions of the investments in the portfolio. E.g., if 50% of the money is in stock A with a beta of 2.00, and 50% of the money is in stock B with a beta of 1.00,the portfolio beta is 1.50.
What is the beta of a portfolio which consists of the following?
The beta of a portfolio is a weighted average of the betas of the assets in the portfolio. Since the risk-free asset has a beta of zero, increasing the weight of stock A and decreasing the potion in the risk-free asset will increase the beta of the portfolio. A portfolio is comprised of two stocks.
What are the betas of the two stocks?
Essentially, beta expresses the trade-off between minimizing risk and maximizing return. Say a company has a beta of 2. This means it is two times as volatile as the overall market. We expect the market overall to go up by 10%.
What is the role of beta in portfolio theory?
Beta forms the core of the CAPM, which is used to calculate the cost of equity, which is an important input for valuation of a stock. Higher the Beta higher is the compensation that investors will expect from the stock and vice versa.
What factors determine the beta of a stock?
Three factors that affect Beta values
- Nature of the business. Usually, the earnings of a company keep on fluctuating with time due to the business cycles. …
- Financial leverage. Financial leverage is described as the debt portion of the financial structure of a company. …
- Operating leverage.
Does beta measure systematic risk?
Beta is the standard CAPM measure of systematic risk. It gauges the tendency of the return of a security to move in parallel with the return of the stock market as a whole. One way to think of beta is as a gauge of a security’s volatility relative to the market’s volatility.
What does β beta mean in risk management?
The beta (β) of an investment security (i.e., a stock) is a measurement of its volatility of returns relative to the entire market. It is used as a measure of risk and is an integral part of the Capital Asset Pricing Model (CAPM). A company with a higher beta has greater risk and also greater expected returns.
What does a high beta mean for stocks?
A stock that swings more than the market over time has a beta above 1.0. If a stock moves less than the market, the stock’s beta is less than 1.0. High-beta stocks are supposed to be riskier but provide higher return potential; low-beta stocks pose less risk but also lower returns.
