Answer:The New Divisor for the price weighted index = 4.29 (rounded off to two decimals)
Explanation:
Able stock = $93
Baker = $351
Charlie = $74
Price Weighted Index Formula = sum of company share prices/number of companies
Price Weighted Index Formula = ($93 + $351 + $74)/5
Price Weighted Index = $425/5 = $85
The Price Weighted index before share split = $85 and the divisor is 5
Calculating the New Divisor for the Price weighted index
Let The new divisor for the price weighted index be α
Price of Barker stock after sare split = $351 x 1/2 = $175.5
Price Weighted Index = 85
Price Weighted Index= ($93 + $175.5 + $74)/α = $85
($93 + $175.5 + $74)/α = $85
cross multiply
$85α = ($93 + $175.5 + $74)
$85α = $342.5
α = $342.5/$85 = 4.29411765
α = 4.29
The New Divisor for the price weighted index = 4.29 (rounded off to two decimals)
