A US Treasury bill has a beta of 0 while the overall market has a beta of what?

Beta is the measure of a security's volatility compared to the volatility of the market as a whole. Therefore, the market as a whole has a beta of 1.


How can you measure volatility using beta?

You can use Beta to measure market volatility because of beta is the elasticity of a stock change as a result of a change in the market. That is, Beta of a sotck is found by comparing the senstivity of a stock's return to the fluctuations in the market.Beta is found by dividing the product of the covwariances of the stock and market retun by the variance of the market.The bench marks of betas are as followed:a risk free investment such as a Tbill (that is guaranteed a return) will have a beta of 0.A portfolio with risk equivalent to the market has a beta of 1.Given those two bench mark, you can gauge at the volatility of the stock/investment by comparing its beta with those two extremes.


Does a risk free asset have a beta of one?

No, a risk-free asset does not have a beta of one. In finance, the beta of an asset measures its sensitivity to market movements, with a beta of one indicating that the asset moves in line with the market. A risk-free asset, such as a Treasury bond, has a beta of zero because it is not correlated with market fluctuations and carries no risk of default.


What does it mean by positive beta in finance?

A positive beta means that the asset generally follows the market. A negative beta shows that the asset inversely follows the market; the asset generally decreases in value if the market goes up and vice versa.


If a stock has a beta equal to one?

A beta of 1 indicates that the security's price will move with the market.


Does beta measure nondiversifiable risk?

Yes, beta measures the sensitivity of an asset's returns to market movements, representing the nondiversifiable risk (systematic risk) of an investment. A beta of 1 indicates that the asset moves in line with the market, while a beta greater than 1 implies higher volatility, and a beta less than 1 indicates less volatility than the market.


What is debt beta?

Beta of a debt is the ration of covariance of the debt return with the market return.If debts are traded then beta of the debt is estimated by regression.


If portfolio a has a beta of 1.5 and portfolio z has a beta of -1.5 what do the two values indicate?

Simple scenario: Taking into account beta of index is set at 1.0; Lets say market increases by 5% Beta of 1.5 would indicate that the particular portfolio would increase by 7.5% as for beta of -1.5, the portfolio would decrease by 7.5% Beta is a measure of sensitivity of market base on the reference index. Negative beta would mean that the portfolio is inversely proportional to market performance.


Why market beta is always 1 How is it calculated?

by calculations


Is Beta is the slope of the security market line?

yes


What does beta measures?

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.


2 Scenarios If market return is 5 percent stock's expected return is -2 percent If market return is 25 percent expected return is 38 percent What is its beta?

The beta is the relationship of a stock's expected return to the broad market's return. A "high beta" stock will have a beta over 1.00, and thus move up more than the market when the market is advancing, and decline more than the market when the market is declining. A "low beta" stock will decline less than the market, or advance less than the market, depending. The problem with beta is that it assumes a linear relationship, and what you describe here clearly is not. Your stock falls when the market rises a little, and rises more than the market when the market is advancing. To calculate beta, you should look at a longer term analysis of your stock and the market -- say, weekly observations over a year. Most betas are calculated using this length of data. But check formulas -- many different ones are out there. Also remember that beta is only one measure of a stock's performance. Alpha is the performance of a stock that cannot be explained by its beta and the broad market movement. And of course, all of this is a "hypothesis" of market behavior which is useful in understanding broad actions, but very weak in predicting individual stock behavior.
