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.
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.
