I am working on a project which involves comparing my calculated divisor against the actual dow divisor on Feb 1st 2007. I’ve tried the DJ website and other financial sites for hours but have been unsuccesful finding the divisor for the closing day on 2-1-2007.

My calculation comes out to:

\*\*.124824833829 \*\*

2-1-07, 1581.99 _(sum of stock price of all 30)_/x = 12,673.68 _(given index value)_

Any finance dopers happen to know the exact official divisor given by DJ for the DJIA for that date so I can compare?

It should be in the Wall Street Journal for that date.

(with no cite) – which matches your number.

The divisor changed on April 2 of this year

> The price adjustment of Altria Group Inc. (MO) due to a distribution of Kraft Foods Inc. (KFT) shares will be effective for the open of trade on trade date April 2, 2007.
> 
> As a result, the new divisor for the DJIA is: 0.123051408

But your best bet is probably a trip to a library to grab the 2-1-07 Wall Street Journal.
