Computational Problems 4-1 Assume that the DJIA closed at 10,875 one day recently, and the divisor was 12493117 a. What is the sum of the prices of the 30 stocks in the index, given this information? b. Assume that one stock in the index, Pfizer, moved 54 40 that day, while the index itself moved about 105 points (to close at 10,875). What percentage of the total movement in the DJLA that day was accounted for by the movement in Phizer? c. Now assume that one of the 30 stocks had a 2-for-1 stock split that day, declining from $47.50 to $23.75. What would the new divisor have to be to keep the index unchanged at 10,8752
