10/15/09 Stockholm, Sweden – Now that Wall Street hearts are a-flutter with Dow 10,000, it’s worth taking a moment to figure out what the Dow Jones Industrial Average actually tells us about its components. The Dow is a share price-weighted average, meaning that when the index is figured out the companies with larger share prices carry more weight.
This means that the companies currently with the largest share prices make up a greater portion of the Dow’s weight than other companies with a lower share price. These large share price companies include IBM (nearly 10 percent of the Dow), 3M (over 5 percent), and Chevron (over 5 percent), among others.
The Dow components that have been hit the hardest, like Bank of America and Pfizer, now carry substantially less influence on the Dow as a whole. General Electric, for example, has only a 1.27 percent weight in the Dow.
It’s another example of how the ongoing parade of “encouraging” numbers seem to ring hollow when you dig a little. See The Reformed Broker for the full analysis and more insight into how the Dow broke 10,000 because IBM shares haven’t split very often.

how much is the dow up when you calculate its devalued dollar worth. at least we will be able to get a “big mac bowl of soup” next year.
