4 Firms and economic uncertainty 2: IBM and Dell (examples from class) This exercises ask you to compute the summary statics describing the distribution of IBM and Dell that we have seen together in class. Table 2 shows you the expected return of IBM and Dell in three different economic scenarios (Recession, Normal Times, Economic Boom), and the respective probability that each scenario will take place. Table 2: Returns and probilities of different economic scenarios 1. What is the expected return of IBM? What is the expected return of Dell? 2. What are the Variance and Standard Deviation of IBM? What is the Variance and Standard Deviation of Dell? 3. What is the covariance between the returns of IBM and Dell? 4. What is the correlation between the returns of IBM and Dell? 4 Firms and economic uncertainty 2: IBM and Dell (examples from class) This exercises ask you to compute the summary statics describing the distribution of IBM and Dell that we have seen together in class.
