That list is entirely misleading, of your non-asterixed list:
- Allied Signal purchased Honeywell (but adopted their name) and is currently a $72B company.
- Alcoa is still a $20B company.
- American Can became Primerica, which was the foundation of Citigroup which is a $150B company.
- Bethlehem Steel was mostly shuttered but is still operating under foreign ownership.
- Dupont is still a $60B company.
- Kodak we all know, but still a $1B company.
- GM had its issues but still employs over 200,000 people directly and is a $55B company.
- Goodyear is still a $7B company.
- Vale Inco is still a $75B company.
- International Harvester was merged into Navistar which is still a $4B company.
- International Paper still employs over 60,000 people and is a $21B company.
- OI is still a $5B company.
- Phillip Morris rebranded / merged to form Altria group which is an $80B company.
- We all know Sears' issues, but they're still a $4B company.
- Texaco's production operations were merged into Chevron ($250B company) and their retail operations were merged into Shell ($150B company).
- Dow Chemical bought Union Carbide for almost $10B and the combined company is today worth $60B.
- United Technologies is still a $100B company.
- US Steel is still a $5B company.
- Westinghouse bought CBS and rebranded to CBS Corp. ($35B company) and sold off its power business overseas and the rest of its electrics business to Toshiba.
- Woolworth rebranded to Foot Locker and is still worth $7B.
So maybe two on the list no longer exist, but the vast majority are still massive companies collectively employing millions of people with hundreds of billions (trillions?) in revenue. Their inclusion on or exclusion from the DJIA doesn't mean much about their competitiveness or their success.
