Green bowel movements are very common and usually no cause for concern. People generally expect their stools to be a consistent brownish color, but it doesnât take much to cause that to change. Any change in stool color can be very alarming, but the cause is almost always benign.
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. Beta is also known as the beta coefficient.
In finance, the beta (Î² or beta coefficient) of an investment indicates whether the investment is more or less volatile than the market as a whole. 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. Volatility is measured as the fluctuation of the price around the mean: the standard deviation.
