c. Predict sales in 15 years.
Go to Yahoo!Finance and download data at the MONTHLY frequency for the stock Apple Inc. with ticker AAPL with starting date January 1, 1990 and end date August 4, 2016. Use the ADJUSTED CLOSING PRICE to create the monthly
RETURNS that are the percentage change of the adjusted closing price (NB: make sure to sort first the price from OLDEST TO NEWEST; the percentage return is 100 times the price change between the current and previous month divided by the
price in the previous month).
Based on the time series of the stock return, answer the following questions (NB: you should have 319 monthly returns):
Calculate the sample mean or average of the stock return:
Calculate the sample standard deviation of the stock return:
!!! For the questions below, use the values for the mean and std. dev. that you typed above (only the first 2 decimals)!!!
Assuming that the returns follow a normal distribution:
Calculate the P(return > 2.21):
Calculate the P(-12.37 x) = 0.9704:
