6. There are two ways to calculate the mean of a series of data. The arithmetic an, written in the form i 1 takes the sum of that series and divides by the number of data points. A geometic mean, on the other hand, takes the product of a group of n data points, where each is raised to the exponent 1/n, Using a geometric mean and natural logarithms gives less weight to outliers than an arithmetic mean. Using the...
Calculate the arithmetic mean, the geometric mean, sample standard deviation, and correlation coefficient of the Bonds and Small Cap Stocks. To really test your skills, calculate the expected return and risk of a 30% Bond & 70% Small Cap Stock portfolio. Estimate the weights of each asset class where you think the Minimum Variance portfolio (MPV) be located on the risk & return graph.
