How come in the answer they use the ending market period to calculate return?
To me, the correct method is to do a weighted average of the stock price changes using the Market Cap at 1/1/09 as weight.
The problem says no stock splits or dividends, so the only reason for a difference between the price change and the market cap change is an acquisition or a spinoff, neither of which would cause a value weighted index to apprecaite.
I got equally weighted as very narrowly beating out price weighted.
thanks for any help in advance.作者: Darien 时间: 2011-7-13 13:27

This example is directly out of the book...the book would be better than anyone else telling you how to do it.作者: ll11 时间: 2011-7-13 13:27
Where is the example in the book? Do you mean Reading 32, page 208? the example here has market value changing by the price change.作者: lcw77 时间: 2011-7-13 13:27
Logically, something is wrong in both the book example and the mock exam.
If there are no changes in shares outstanding, mathematically the price change and market value change would be the same - but it's not!
I'm gonna go with their 'total market cap' approach from the book if this comes up on the exam!作者: zwjy 时间: 2011-7-13 13:27
At risk of being shot for not consulting the book first -- I was reviewing this today, and i see how they determined that market cap > price weighted, but how did they calculate equal weighted rate of return?作者: lcai 时间: 2011-7-13 13:27

I think it is more just to show the example than anything else.作者: mar350 时间: 2011-7-13 13:27
Equally weighted : 13.72%, why value-weighted (13.5%) will result in the largest return ?
And price-weighted = 63.9/56.41 - 1 = 12.37% ?作者: mp3bu 时间: 2011-7-13 13:27

Sum up the returns, divide by 5.作者: susana 时间: 2011-7-13 13:27
For the price column? would that not be price weighted?作者: oneboy 时间: 2011-7-13 13:27
I got 13.72 aswell but for equal you equally weight the price weighted returns not the market cap ones作者: former 时间: 2011-7-13 13:27

Why changes in prices (%) are used to calculate ?
Shall it be : (8.2+26.0+13.2+9.1+12.1) / 5 = 13.72% ?
