Is the beta of a stock static or dynamic?
The Beta of a stock is always dynamic.
Why beta rays get negative?
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.
Why is beta the correct measure of a stock riskiness?
Beta measures a stock's volatility (the swings up and down in price). The market as a whole has a beta of 1.0, but each stock is determined a beta value from a history of it's stock movements. Riskiness equates to the stock losing value and high beta stocks are more prone to falling faster.
How can I calculate the portfolio beta by weighting individual stock's betas?
To calculate the portfolio beta by weighting individual stock's betas, you would multiply each stock's beta by its weight in the portfolio, and then sum up these values to get the overall portfolio beta.
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.
What type of charge does beta radiation have?
Beta radiation can have a negative charge (β-) or a positive charge (β+). Negative beta particles are electrons, while positive beta particles are positrons.
What would make a firm's beta increase?
The beta of a firm's stock is dependent on the volatility of the stock relative to the overall market. So if the stock's volatility increased relative to the overall market, it's beta would increase as well.
What is the difference between a beta plus particle and a beta minus particle?
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.
Is beta radiation usually positive or negative?
Negative: it can kill you!
What is a charge of beta?
A beta charge refers to the charge carried by a beta particle, which can be either a beta minus (electron) with a charge of -1 or a beta plus (positron) with a charge of +1. Beta decay is a type of radioactive decay process involving the emission of beta particles.
What are three types of beta decay?
There are two types of beta decay, and they are beta plus (beta +) decay and beta minus (beta -) decay. A post already exists on beta decay, and a link to that related question can be found below.
Are beta particles positive or negative?
Beta particles can be either positive or negative. It depends if an electron or a positrion is emited. Usually though, beta particles are negative as it is much more common for an electron to be emitted (though that does depend on the substance).
