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. Beta is a measure of an investment's relative volatility. The higher the beta, the more sharply the value of the investment can be expected to fluctuate in relation to a market index. For 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%.
