Yes, it is possible that a risky asset may have a negative beta.
Given that beta measures "relative risk" to a particular market, index, etc., a negative beta suggests that the the particular asset class performs well when the given market (the market/index to which the beta was computed) performs poorly (negative coorelation).
Using the phrase "risky asset" only suggests that the asset's ability to return value to the investor is volatile.
For example, a new set of ETFs released in November 2008 track the Case-Shiller housing index. The first, UMM (NYSE), goes up when home prices go up. The second, DMM (NYSE), goes down when home prices go down. If we assume that the Case-Shiller index is the basis for beta computations, one would expect UMM's beta to be positive (2.0 since the securities have leverage of 200%) and DMM's beta to be negative (-2.0).
At the end of the day, negative beta opportunities are good in that they provide a way to diversify out different types of risk in a portfolio holding multiple asset classes.
In the context of the Capital Asset Pricing Model how would you define beta? How are beta determined and where can they be obtained? What are the limitations of beta?
A beta coefficient measures the sensitivity of an asset's returns to the returns of a benchmark, typically a market index. In finance, it indicates how much an asset's price is expected to change in relation to a 1% change in the benchmark. A beta greater than 1 suggests higher volatility and risk compared to the market, while a beta less than 1 indicates lower volatility. Investors use beta to assess the risk profile of investments and to make informed portfolio decisions.
The Capital Asset Pricing Model (CAPM) is a financial model that establishes a relationship between the expected return of an asset and its systematic risk, measured by beta. It suggests that the expected return on an investment is equal to the risk-free rate plus a risk premium, which is proportional to the asset's beta and the market risk premium. CAPM is widely used in finance for asset pricing and portfolio management, helping investors assess the potential return of an investment relative to its risk.
In finance, the Beta (β) of a stock or portfolio is a number describing the correlated volatility of an asset in relation to the volatility of the benchmark that said asset is being compared to. This benchmark is generally the overall financial market and is often estimated via the use of representative indices, such as the S&P 500
The portfolio consists of four stock: A, B, risk-free asset and the market. The weights will be 0.25 each and the portfolio beta = (0.25 x 0.8) + (0.25 x 1.2) + (0.25 x 0) + (0.25 x1) = 0.75 Akshita Mehta
The amount of systematic risk in a particular risky asset, relative to an average risky asset, is measured by its beta coefficient. A beta greater than 1 indicates that the asset is more volatile than the market, meaning it has higher systematic risk, while a beta less than 1 suggests it is less volatile and carries lower systematic risk. If the beta is exactly 1, the asset's risk is equivalent to that of the average risky asset. Systematic risk reflects the inherent market risk that cannot be diversified away.
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.
The negative sign in beta represents the inverse relationship between the return on an asset and the return on the overall market. A negative beta suggests that the asset tends to move in the opposite direction of the market, indicating that it is likely to perform well when the market declines and vice versa. This negative correlation can be valuable for diversification purposes in a portfolio.
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.
In the context of the Capital Asset Pricing Model how would you define beta? How are beta determined and where can they be obtained? What are the limitations of beta?
The asset beta reflects the risk of the firm's underlying assets, independent of its capital structure. When the debt-to-equity ratio rises, the firm's financial leverage increases, which may affect the equity beta but not the asset beta itself. The asset beta remains constant because it is based on the business's operational risk and market conditions, rather than the financing mix. Therefore, while the equity beta adjusts to reflect the higher financial risk, the asset beta remains unchanged.
Beta rays do not have a negative charge. Beta particles (electrons or positrons) emitted during beta decay can have a negative or positive charge, depending on whether it is an electron or a positron. The negative charge is carried by the electron beta particle.
Normally, Asset Beta takes account of only business risks while Equity Beta takes account of both business and financial risks. For further information, get hold of a good corporate finance textbook.
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.
beta
Beta radiation can have a negative charge (β-) or a positive charge (β+). Negative beta particles are electrons, while positive beta particles are positrons.
The difference between a beta plus and beta minus particle is the electrical charge. The charges are equal, but opposite. The beta minus particle is an electron with a negative charge, while the beta plus particle is an anti-electron or positron with a positive charge.
