Maybe this surfaced before, but I see today that DIA traded from 111.15 up to 112.32 and DJX was 111.02 to 112.41 (as of 2:21 pm EDT). Right now my monitor shows DIA up .99 and DJX up 1.36. Any reason why these two dow measures don't track more closely ? I understand there is a dividend payout consideration for DIA's, but on an intraday basis, shouldn't they be closer in price action ?
