[edit] Indexes vs. Indices
According to the Journal of Financial Economics: "'Indices' as the plural of 'index' is appropriate for mathematical terms, but the plural of 'stock index' is 'stock indexes.'"
I have made appropriate changes.
I've heard some significant figures, e.g. John Templeton, say flatly that all stock market indexes are ethical indexes with respect to the buying public's minimum criteria to trust *any* stock - and that over time all indices in all industries must emulate the ethicals in applying mechanical criteria such as scenarios (so-called 'mark to future'). That standards for the index may go down over time but the buying public will not want sudden surprises on scale of Enron. Biggest noise on this subject is Ron Dembo.
If that's even remotely true, ethicals and mechanicals require much much more space than industry indices.
Warren Buffet is more of a disclosure bug...
- Can someone explain how the index figures are calculated? adamsan 15:56, 31 Dec 2004 (UTC)
[edit] inflation-correction
I'm a newcomer, so I'm just writing this as a suggestion.
I use the US as an example here. Stock prices are in US$, and so are the various indexes/averages of them. Values of an index from (very) different times are commonly compared. The purchasing power of the US$ has declined a lot over time. So, sound representation of an index is showing it in terms of purchasing power, i.e., after inflation-correction.
I suggest that this point be strongly incorporated into the article "Stock market index".
[edit] The formulars
Can anyone give some of the basic formulars used in indexing and assumptions made.
I think a pro and cons sectios would also be beneficial.Kendirangu 08:37, 14 June 2007 (UTC)
[edit] For an encyclopedic entry, this one is subpar!
The author of this article has presumed that the readers are graduates of economics and financial analysis and has drowned the theme with jargon. Instead of giving a simplified explanation as to how and what factors the indices depend on and how is this reflected on the state of economy as a whole!
Someone please do a rewrite! —Preceding unsigned comment added by 122.163.180.237 (talk) 01:26, 9 September 2007 (UTC)
[edit] Citation for awards?
There's a whole section of this entry that lists awards for indexes without any mention of the awarding body... Mlwalla (talk) 20:32, 27 December 2007 (UTC)
[edit] Rampant use of: [citation needed]
Some statements are so outlandish that they cannot be made without some sort of citation. Especially this one: "However, empirical tests conclude that market indexes are not efficient" Whose empirical tests? Where? When? How do I know those tests weren't bulls*-t etc.? —Preceding unsigned comment added by ToyotaPanasonic (talk • contribs) 02:47, 14 January 2008 (UTC)
