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 $4.40 that
day, while the index itself
moved about 105 points (to close at 10,875). What percentage of the
total movement in
the DJIA that day was accounted for by the movement in
Pfizer?
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
10,875?
