- A beta of 1.0 means the stock moves equally with the S&P 500.
- A beta of 2.0 means the stock moves twice as much as the S&P 500.
- A beta of 0.0 means the stocks moves don’t correlate with the S&P 500.
- A beta of -1.0 means the stock moves precisely opposite the S&P 500.
What does low negative beta mean?
A beta value that is less than 1.0 means that the security is theoretically less volatile than the market. Including this stock in a portfolio makes it less risky than the same portfolio without the stock. For example, utility stocks often have low betas because they tend to move more slowly than market averages.
How can Beta particles be negatively charged?
In negative β- decay a neutron in the nucleus is transformed into a proton, an electron and an antineutrino. Hence, in radioactive decay process, the negatively charged emitted β- particles are the electrons produced as a result of the decay of neutrons present inside the nucleus.
Do negative attracts positive?
The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all things are made up of charges. Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative).
Is a negative beta defensive?
If beta is less than one, the returns on the company stock are less volatile than the market return. A company stock with beta less than one is called a defensive stock.
What happens when beta positive?
A positive beta value indicates that stocks generally move in the same direction with that of the market and the vice versa. Also see: volatility, CAPM, NSE Nifty, alpha.
What is positive beta decay?
In positron emission, also called positive beta decay (β+-decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but…
Is beta the type of radiation with a negative charge?
Beta particles (β) are small, fast-moving particles with a negative electrical charge that are emitted from an atom’s nucleus during radioactive decay. These particles are emitted by certain unstable atoms such as hydrogen-3 (tritium), carbon-14 and strontium-90.
