The following three defense stocks are to be combined into a stock index in January 2013 (perhaps a portfolio manager believes these stocks are an appropriate benchmark for his or her performance). Assume the index is scaled by a factor of 10 million; that is, if the total value of all firms in the market is $5 billion, the index would be quoted as 500.

Douglas McDonnell	360		$	65		$	69		$	83
Dynamics General	450			52			46			60
International Rockwell	170			81			70			86
