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.
Alpha is a measure of the active return on an investment, the performance of that investment compared to a suitable market index. An alpha of 1% means the investment's return on investment over a selected period of time was 1% better than the market during that same period, an alpha of -1 means the investment underperformed the market. Alpha is one of the five key measures in modern portfolio theory: alpha, beta, standard deviation, R-squared and the Sharpe ratio.
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%.
