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 2010 (perhaps a portfolio manager believes these stocks are an appropriate benchmark for his or her performance): a. Compute the rate of return on an equally weighted index of the three defense stocks for the year ending December 31, 2010 . (Negatlve amounts should be lndlcated by a minus slgn. Round your enswer to 2 declmel pleces. Omlt the "\%" slgn ln your response.) b. If the index value is set to 100 on January 1,2010 , what will the index value be on January 1, 2011 ? (Round your answer to 2 decimal pleces.) c. What is the rate of return on the index for 2011 ? (Round your answer to 2 declmal pleces. Omlt the "\%" slgn In your response.)
