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.
Beta is calculated by using regression analysis; one should think of beta as the tendency of a security's returns to respond to swings in the market. A beta of 1 indicates that the price of a security will move in tandem with the market; a beta less than 1 means that the security will be less volatile than the market.
