Expert Solution

A price-weighted index only considers the market price i.e. the index value is the sum of all the market values of stock present in that index and weights are assigned according to their respective market price upon total index value.

PRICE WEIGHTED INDEX ON JANUARY 13TH = (25+40+30)/3 = 31.667

split price after stock Z splits = Closing Price/ratio = 30/5 = 6

divisor at the beginning of January 14th = ( sum of all closing prices after split on 13th )/PRICE WEIGHTED INDEX ON JANUARY 13TH = (25+40+6)/31.667 = 2.242

PRICE WEIGHTED INDEX ON JANUARY 15TH = (27+42+8)/2.242 = 34.344

split price after stock X splits = Closing Price/ratio = 27/2 = 13.5

divisor at the beginning of January 16th = ( sum of all closing prices after split on 15th )/PRICE WEIGHTED INDEX ON JANUARY15TH = ( 13.5+42+8 )/34.444 = 1.844

PRICE WEIGHTED INDEX ON JANUARY 16TH = ( 14+44+10 )/1.844 = 36.876

RETURN FROM JAN 13 TO JAN 16 = (36.876 - 31.667)/31.667 = 16.449%
