Dow bubble?

Dow is "collection" of 30 shares. This way they call it Dow30.

As you all know, back in 1999-2000 the Dow hit all time high.

Recently, Dow hit again, and made new all time high.

However, if we study carefuly the market price on each company in Dow back in 1999-2000 and now, we will see something strange.

Only 10 companies now are traded at higher price than in 1999-2000, and one (MCD) is on similar level.

Here is the list:

1. American Express Company
2. Boeing Co.
3. Citigroup, Inc
4. Caterpillar Inc
5. Johnson & Johnson
6. 3M Co
7. Altria Group Inc
8. The Procter & Gamble Company
9. United Technologies Corporation
10. Exxon Mobil Corp

And finaly MCD:

1. McDonald's Corporation - at about same level

So hows that? 1/3 of the index is going, but then, this means 2/3 is down. So then why Dow is up? Probably because of capitalization and so on.

I am very curious about S&P 500, but this has to be made with a program and I have no time of it right now.
