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.
Statistical analysis of mutual funds requires a fundamental knowledge of quantitative measures, such as Beta, R-squared, Alpha, Sharpe Ratio, Expense Ratio, and Tax Cost Ratio: 1  Beta: Beta, with regard to mutual fund investing, is a measure of a particular fund's movement (ups and downs) compared to the overall market. For reference, the market is given a beta of 1.00. If a fund's beta is 1.10, this fund would be expected to have a return of 11% (1.10 is 10% higher than 1.00) in an up market but the same fund would be expected to decline 11% when the market declines 10%.
