Beta Beta (UK /ˈbiːtə/ or US /ˈbeɪtə/; uppercase β, lowercase β, or cursive ϐ; Ancient Greek: βῆτα bḗta or Modern Greek: βήτα víta) is the second letter of the Greek alphabet. In the system of Greek numerals it has a value of 2. In Ancient Greek, beta represented the voiced bilabial plosive /b/.

- Positron emission or beta plus decay (β + decay) is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino (ν e). Positron emission is mediated by the weak force.

- What is '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), which calculates the expected return of an asset based on its beta and expected market returns.

- The Beta is defined as a measure of the volatility of a stock relative to the overall market. A beta of less than one indicates lower risk than the market. A beta of more than one indicates higher risk than the market. NASDAQ.com uses the S & P 500 as the underlying index to measure the overall market for beta.

What is âbetaâ? Beta is a measure of how a particular stock's price moves relative to the market as a whole. It is usually described as a measure of volatility. There are individual stock betas and industry betas. A beta of one indicates that the stock's price moves exactly with the overall market. For example, if the market goes up 20%, the stock price goes up 20%. Market down 10%, stock down 10%. This is, of course, calculated over a period of months and does not necessarily hold true on a daily basis.

- What Causes Vaginal Yeast Infections? Having small amounts of Candida on the skin and inside the mouth, digestive tract, and vagina is normal. A healthy immune system and some good bacteria keep the amount in a person's body under control. But yeast in the vagina can sometimes overgrow and lead to symptoms of a yeast infection.

Beta decay In β+ decay, or positron emission, the weak interaction converts an atomic nucleus into a nucleus with atomic number decreased by one, while emitting a positron (e+) and an electron neutrino (ν e).n nuclear physics, beta decay (β -decay) is a type of radioactive decay in which a proton is transformed into a neutron, or vice versa, inside an atomic nucleus. This process allows the atom to move closer to the optimal ratio of protons and neutrons.

- A beta particle is either an electron or a positron emitted by an atomic nucleus in beta decay, which is a type of radioactive decay. The phenomenon of beta decay involves a c … hange within the atomic nucleus of an atom.eta particles are actually electrons (-e) or can be  positrons.The mass of one electron or beta particle is  9.1095*10-31 kilograms or  0.000548597 AMU which is about 1/20 … 00 times the mass of a  proton or neutron.

3 Options Trades on Volatile Stocks Beta is the secret weapon behind these trading ideas. View All. Beta is more than just a fraternity word or a phase in software or web development that happens before the official launch. In investing vernacular, it’s a way of measuring how volatile an individual stock is relative to the broader market. With greater risk of volatility comes the potential for greater reward — if the market moves 3% higher, for example, a stock with a beta of 2.0 theoretically should advance 6%. But of course, this also is true if the market declines 3%. Ouch.

Ch. 5 Statistical Measurement Tools 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. 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. Many utilities stocks have a beta of less than 1.

Beta A beta is any software still under development that is made available to a select few to test, examine, and report problems they face. Beta testing allows developers to find problems they may have missed and fix them before the program is released. Closed Beta vs. Open Beta. Often there are two beta testing phases, open beta and closed beta. An open beta also known as a public beta is beta testing open to any user, who is known as a beta tester. Closed beta is beta testing only available to a select few individuals or only company employees. How to be a beta tester Many games (especially online games) in the final stages development have an open beta for several months that allows anyone interested in the game to play and report problems.

Beta decay Beta decay is a consequence of the weak force, which is characterized by relatively lengthy decay times. Nucleons are composed of up or down quarks, and the weak force allows a quark to change type by the exchange of a W boson and the creation of an electron/antineutrino or positron/neutrino pair.

What does BETA stand for? (ie. yahoo answers beta) What does it mean?? A beta version or beta release usually represents the first feature complete version of a computer program or other product, likely to be unstable but useful for internal demonstrations and previews to select customers. Some developers refer to this stage as a preview, as a technical preview (TP) or as an early access.

Alpha and Beta: CNBC Explains Beta, on the other hand, is based on the volatility—extreme ups and downs in prices or trading—of the stock or fund, something not measured by alpha. But beta, too, is compared to a benchmark, like the S&P 500. You can think of beta as the tendency of a security's returns to respond to swings in the market.

Sample Size Calculator Beta: The probability of a type-II error -- not detecting a difference when one actually exists. Beta is directly related to study power (Power = 1 - β). Most medical literature uses a beta cut-off of 20% (0.2) -- indicating a 20% chance that a significant difference is missed.

Beta (finance) In finance, the beta (β or beta coefficient) of an investment indicates whether the investment is more or less volatile than the market. In general, a beta less than 1 indicates that the investment is less volatile than the market, while a beta more than 1 indicates that the investment is more volatile than the market.
