## Does the risk-free rate have a beta of zero?

Assuming a Beta=0 is the same as to say that the r=Rf. Then, the security under valuation has the same expected earnings as a risk free asset. Finally, the only asset with a risk free rate is assumed to be government bonds. The beta can well be 0 or negative if the expected earnngs are below the risk free rate.

## What asset has a beta of 0?

Beta of 0: Basically, cash has a beta of 0. In other words, regardless of which way the market moves, the value of cash remains unchanged (given no inflation). Beta between 0 and 1: Companies that are less volatile than the market have a beta of less than 1 but more than 0. Many utility companies fall in this range.

## What does a zero beta mean?

A zero-beta portfolio would have the same expected return as the risk-free rate. Such a portfolio would have zero correlation with market movements, given that its expected return equals the risk-free rate or a relatively low rate of return compared to higher-beta portfolios.

## Can an asset have negative beta?

Yes, beta can be negative. To see how and why, consider what beta measures: the risk added by an investment to a well diversified portfolio. By that definition, any investment that when added to a portfolio, makes the overall risk of the portfolio go down, has a negative beta.

## What is a good beta?

A beta greater than 1.0 suggests that the stock is more volatile than the broader market, and a beta less than 1.0 indicates a stock with lower volatility. Beta is probably a better indicator of short-term rather than long-term risk.

## How do you interpret beta?

Interpreting Beta A β of 1 indicates that the price of a security moves with the market. A β of less than 1 indicates that the security is less volatile than the market as a whole. Similarly, a β of more than 1 indicates that the security is more volatile than the market as a whole.

## Is a high beta good or bad?

A high beta means the stock price is more sensitive to news and information, and will move faster than a stock with low beta. In general, high beta means high risk, but also offers the possibility of high returns if the stock turns out to be a good investment.

## What is a beta risk?

What Is Beta Risk? Beta risk is the probability that a false null hypothesis will be accepted by a statistical test. This is also known as a Type II error or consumer risk. In this context, the term “risk” refers to the chance or likelihood of making an incorrect decision.

## What does a beta of 1.5 mean?

Roughly speaking, a security with a beta of 1.5, will have move, on average, 1.5 times the market return. [More precisely, that stock’s excess return (over and above a short-term money market rate) is expected to move 1.5 times the market excess return).]

## What is a good portfolio beta?

For example, a portfolio with an overall beta of +0.7 would be expected to earn 70% of the market’s return under normal circumstances. Portfolios, however, can also have betas greater than 1.0, such that a portfolio with a beta of +1.25 would be expected to earn 125% of the market’s return and so on.

## Can you have negative beta in CAPM?

Interpret the CAPM, II When the covariance is negative, the beta is negative and the expected return is lower than the risk-free rate. A negative-beta asset requires an unusually low expected return because when it is added to a well-diversified portfolio, it reduces the overall portfolio risk.
