Evaluate the General Motors stock. Download the last 1 year daily prices from finance.yahoo.com. Choose a set of intervals ("bins" in Excel) and make a frequency and relative frequency distribution of the observed daily returns (use Excel's FREQUENCY() ), and represent them graphically. Calculate the average return, standard deviation, variance, skewness and kurtosis, minimum and maximum of the distribution. Discuss: what does this distribution look like? Looking at the graph and the computed parameters, how does it compare to a normal probability distribution?
