Talk:Dow Jones Industrial Average
This phrase "Opening of the Dow Jones" seems to be used very loosely. Could it be made somewhat more explicit? Whose figure is used? I complain because [1] effectively says that there's no such thing as the "opening" of the Dow - instead it's the NYSE that opens, and the Dow is just computed from that. For the time calculation, how about less ambiguity like referring directly to 9:30am New York Time (if that's correct), or something? 130.194.80.156 08:32, 20 June 2008 (UTC)
- Nearly every finance-page lists the value for the DOW's "Opening". No matter how it is defined internally, that's simply the value used for the calculation. --Hermann 22:58, 3 July 2008 (UTC)
- Nearly every finance-page lists a different DJ opening value. Channel N24's teletextpage, which you added to this page for manual use, only shows one decimal place, as does channel Pro7. If I use that value in my offline calculator, I get coordinates which are different from irc.peeron.com. Channel n-tv shows 2 decimal places, but yesterday (2008-09-17) they were slightly different from irc.peeron.com, leading to very different coordinates. This either means that there are multiple correct coordinates for every day (which I think is not a good idea) or that only the official implementation's coordinates (i.e. the finance.google.com opening value, which seems to be identical to finance.yahoo.com's) may be used.

- Ack, and as we found out the hard way, the value is still being adjusted after its initial posting. -- Relet 20:00, 18 September 2008 (UTC)
- The comic itself reserves space for two decimal places. Do sources agree on the value of these at least? Let's find out how that opening value is actually calculated. -- Relet 20:49, 30 September 2008 (UTC)
- I don't know what n-tv lists as opening price, but it differs so blatantly, that it must be something different. Possibly the dow jones index at the opening of the European stock market? -- Relet 21:06, 30 September 2008 (UTC)

Here are lists of historical prices of the DJI from various sources: Anybody find a difference? -- Relet 21:01, 30 September 2008 (UTC)
- http://finance.google.com/finance/historical?q=INDEXDJX:.DJI
- http://finance.yahoo.com/q/hp?s=^DJI
- http://money.cnn.com/quote/historical/historical.html?symb=DJI <- not actually listing opening prices on that page. Still looking for a better link. :\
N-tv differing wildly from everything: http://www.derivate.n-tv.de/showpage.asp?pageid=72&inbwnr=387 <- "Eröffnung" means opening.
- Opening differs between Yahoo and Google for August 24 2010! --Fasanen 09:23, 26 August 2010 (UTC)
- Where did you see this? Here are the values that were retrieved automatically for 2010-08-24 by my "source" with the corresponding timestamps (DJ local time):

- I visited the Yahoo link above. It displays an opening of 10170.86 for 2010-08-24. --Fasanen 06:34, 27 August 2010 (UTC)
- that's obviously a mistake/bug then :o) it's not uncommon, that's why my source waits for three different sources to agree before giving out the opening value... --Crox 16:49, 27 August 2010 (UTC)
