In addition to price-weighted and value-weighted indexes, an equally weighted index is one in which the index value is computed from the average rate of return of the stocks comprising the index. Equally weighted indexes are frequently used by financial researchers to measure portfolio performance. The following three defense stocks are to be combined into a stock index in January 2016 (perhaps a portfolio manager believes these stocks are an appropriate benchmark for his or her performance): Price Shares (millions) 190 450 330 Douglas McDonnell Dynamics General International Rockwell 1/1/16 $105 68 97 1/1/17 $111 64 86 1/1/18 $124 78 102 a. Compute the rate of return on an equally weighted index of the three defense stocks for the year ending December 31, 2016. (A negative value should be indicated by a minus sign. Do not round intermediate b. If the index value is set to 100 on January 1, 2016, what will the index value be on January 1, 2017? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Answer is complete but not entirely correct. Index value 6.20 X
