1. Download time series of daily and monthly prices for IBM for 1963-2009.
a. Are there any differences in skewness of daily and monthly returns?
b. Are there any differences in skewness of continuously compounded versus simple
c. Are there any differences in kurtosis of daily and monthly returns?
d. Are there any differences in kurtosis of continuously compounded versus simple
3. Do the followings for daily and monthly continuously compounded returns:
a. Plot the time series returns. What can you say about the picture?
b. Plot the histograms and tell what you infer about the true distribution of the stock returns. Hint: Is the return distribution normally distributed?
c. Do part a and b for simple returns. Compare the results with the ones for continuously compounded returns. Describe any notable features.
4. Download time series of daily and monthly prices for the daily S&P index for 1963-2009. Compute continuously compounded returns and plot time-series as well as the histogram. Compare to daily IBM return results in Q1.
5. Compute the sample auto-covariances and auto-correlations for both daily and monthly continuously compounded returns for k=1,...,22 for both IBM and the S&P index. Plot the autocorrelation functions. Do you see any differences between the S&P index and IBM?
