Value line and nikkei dow jow use which methode to compute holding period return? a) arithm. mean arithm mean b) geom. mean geo m. c) arithm. geom. d) geom. arithm. Really important question.
D
They are both price weighted index, So lets say… b
price weighting can’t be geometric?

value line is unweighted index (equally weighted) - dont know if it is geom or arith since equally weighted can be both types?
hpr?

cfaisok, calculating the index value is not related to holding period return (HPR), so I’m not sure I understand the question. HPR is index value at year end minus index value at beginning divide by index value at beginning, but that’s not something Value Line or Dow Jones do. They calculate the index value throughout the trading day, which is basically the arithmetic average of prices, nothing to do with HPR. Comments?
I don’t even know what value line is.
Nikkie and Dow Jones are both price index, so they use arithmetic averages, adjusting for denominator.

Should be: value line aritmetic Nikkey dow jones Geometric Based on how the index is calculated
But if we are calculating the change in the index say year on year, we need mean computation method? While value index and price index is calcualted using arith mean, equally weighted ones can be calculated using both the approaches…
value line is equally weighted

It is between A&D. Equally weighted- calculated both ways- GM and AM. I don’t remember what value line uses.

just looked it up, it’s D: p 46, Reading 53. I am really happy, that i am not the only one beeing clueless 
Thanks for help anyway. Memorize the questition for exam…
it’s just one sentence, they want us to memorize ! Awful.
