- DEFINITION of 'Beta'. 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.Also known as beta coefficient.. beta of less than 1 means that the security will be less volatile than the market. A beta of greater than 1 indicates that the security's price will be more volatile than the market. For example, if a stock's beta is 1.2, it's theoretically 20% more volatile than the market.

Historical Geology/Radioactive decay If the beta decay is negative, it means that an electron is emitted from the atom, then a neutron has to be converted to a proton, and the atomic number is increased by one, changing the atom to a new element; the isotope number stays the same, but the mass of the atom is reduced.f the beta decay is positive, it usually means a proton is turned into a neutron by capturing an electron from the atom's innermost shell; this reduces the atomic number by one, changing the element, but the isotope number stays the same and the emission is a neutrino.

Beta (finance) In finance, the beta (β) of an investment is a measure of the risk arising from exposure to general market movements as opposed to idiosyncratic factors.The market portfolio of all investable assets has a beta of exactly 1.n example of the first is a treasury bill: the price does not go up or down a lot, so it has a low beta. An example of the second is gold. The price of gold does go up and down a lot, but not in the same direction or at the same time as the market.

beta test In software development, a beta test is the second phase of software testing in which a sampling of the intended audience tries the product out. Beta is the second letter of the Greek alphabet. Originally, the term alpha test meant the first phase of testing in a software development process. The first phase includes unit testing, component testing, and system testing. Beta testing can be considered pre-release testing..

What is Beta Decay? Beta decay is a form of radioactive decay in which the nucleus of an atom undergoes a change which causes it to emit a beta particle.The other types of radioactive decay are alpha decay and gamma decay.n beta minus decay, an excess neutron becomes a proton, and the nucleus emits an electron and an antineutrino. The electron is the beta particle, while the antineutrino is a particle with some unusual properties.

Beta Decay Definition Beta Decay Definition: Beta decay refers to the spontaneous radioactive decay where a beta particle is produced. There are two types of beta decay where the beta particle is either an electron or a positron. β- decay occurs when an electron is the beta particle. An atom will β- decay when a neutron in the nucleus converts to a proton by the reaction.

Definition of 'Beta' For example, if a stock's beta value is 1.3, it means, theoretically this stock is 30% more volatile than the market. Beta calculation is done by regression analysis which shows security's response with that of the market. By multiplying the beta value of a stock with the expected movement of an index, the expected change in the value of the stock can be determined. For example, if beta is 1.3 and the market is expected to move up by 10%, then the stock should move up by 13% (1.3 x 10).

Beta Home > Investing > How To Invest > Financial Glossary > B > Beta. The measure of an asset's risk in relation to the market (for example, the S&P500) or to an alternative benchmark or factors. Roughly speaking, a security with a beta of 1.5, will have move, on average, 1.5 times the market return.

- Beta particle. A beta particle, sometimes called beta ray, denoted by the lower-case Greek letter beta (β), is a high-energy, high-speed electron or positron emitted in the radioactive decay of an atomic nucleus, such as a potassium-40 nucleus, in the process of beta decay.

Ch. 5 Statistical Measurement Tools Beta is calculated by using regression analysis; one should think of beta as the tendency of a security's returns to respond to swings in the market. A beta of 1 indicates that the price of a security will move in tandem with the market; a beta less than 1 means that the security will be less volatile than the market.

Definition of beta particle Definition of beta particle. 1) Electron emitted from the nucleus when a neutron decays to a proton and an electron. 3) a charged particle emitted from the nucleus of some atoms as part of those atoms' radioactive decay. Positively charged beta particles are positrons and negatively charged beta particles are electrons.

Beta Beta is used in finance as a measure of investment portfolio risk. Beta in this context is calculated as the covariance of the portfolio's returns with its benchmark's returns, divided by the variance of the benchmark's returns.he letter beta was derived from the Phoenician letter beth. The letter β had the largest number of highly divergent local forms. Besides the standard form (either rounded or pointed,), there were forms as varied as (Gortyn), and (Thera), (Argos), (Melos), (Corinth), (Megara, Byzantium), (Cyclades).

Why value of beta for same company is different on different websites? Bi or beta, is the measure of a specific stock's market risk and shows that stock's volitility relative to the market. Beta is not always constant; it changes sometimes. The most common calculation for beta is to run a regression of the security's past returns against the past returns of the market (above formula).The most current and up-to-date beta would most likely be found in the newspaper in the business section where all the stocks are listed.It would probably be listed with the other stats, like P/E (price earnings). If not found there, try the finance section of Yahoo for a specific company.nswers. Best Answer: The formula looks like this: Ri = Rrf + Bi(Rm-Rrf) Can be read as: R sub i equals R sub rf plus beta (Bi) times R sub m minus R sub rf where R sub i is the required return, R sub rf is return on a risk-free investment, R sub m is the return on the entire market and (Rm-Rrf) is the risk premium.

Beta Beta. A measure of a security's or portfolio's volatility. A beta of 1 means that the security or portfolio is neither more nor less volatile or risky than the wider market. A beta of more than 1 indicates greater volatility and a beta of less than 1 indicates less.or example, Standard & Poor's 500 Index (S&P 500) has a beta coefficient (or base) of 1. That means if the S&P 500 moves 2% in either direction, a stock with a beta of 1 would also move 2%.

What is beta coefficient? Best Answer: A measure of the way in which the price of a stock is correlated to the movement of the market as a whole. The term beta is used to describe a calculation of price volatility. Beta compares a stock’s historical price volatility with the volatility of the market that it is in.

While beta does say something about price risk, it has its limits for investors looking for fundamental risk factors. Beta Beta is a measure of a stock's volatility in relation to the market.By definition, the market has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market. A stock that swings more than the market over time has a beta above 1.0.EE: Beta: Gauging Price Fluctuations. Here we shed some light on what the measure means for investors.

- A crude form of math was first invented by the Sumerians in the sixth century BC. Because the Sumerians had developed a settled, agricultural civilization, they needed math as a way to measure plots of land, tax individuals, chart the sky and develop a lunar calendar.
