Back in July, I caught wind of yet another psychic medium ârealityâ show in development. This one seems tailor-made for Hollywood. Or, should I sayâ¦ âtyler-madeâ? The eight-episode hour-long series âfollows 19-year-old âcelebrity mediumâ Tyler Henry, as he balances his unique abilities with trying to be a regular teenager.â Heâs 20 now.
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.
beta particle. an electron emitted from the nucleus of an atom during radioactive decay of the atom. Beta particles have a range of 10 m in air and 1 mm in soft tissue. Also called beta ray. See beta rays.
