Beta, английский
- 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 meas

- 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. [more precisely, that stock`s excess return (over and above a short-term money market rate) is expected to move 1.5 times the market excess return).] according to asset pricing theory, beta represents the type of risk, systematic risk, that cannot be diversified away. when using beta, there are a number of issues that you need to be aware of: (1) betas may change through time; (2) betas may be different depending on the direction of the market (i.e. betas may be greater for down moves in the market rather than up moves); (3) the estimated beta will be biased if the security does not frequently trade; (4) the beta is not necessarily a complete measure of risk (you may need multiple betas). also, note that the beta is a measure of co-movement, not volatility. it is possible for a security to have a zero beta and higher volatility than the market.
