Buying an equal number of shares does not track the DJIA either. Apple closed at 126.6 the day it replaced ATT. ATT closed at 33.48.

I struggle to see why that is a problem? You will need to rebalance the portfolio, yes.

The DJIA replaced each share of ATT with a share of Apple on a ledger. Without additional investment or buying and selling other assets, there's no way to replicate that in a portfolio due to the difference in share price. Essentially, the DJIA pumped in an ~300% increase in equity value on the ATT shares...or divided among thirty companies a 10% profit.
