not the types of companies you'd want to rely upon as predictors of US market success.
Sounds EXACTLY like good predictors of the U.S. economy.
This besides the fact that I don't think this is what the dow does / should relect in any case. or the alternative methods of determining what's included such as total market capitalisation, most widespread share holder allocation, fasted risers, faster fallers
The fact that they will go bamkrupt DUE TO THEIR MISMANAGEMENT will cause them to disappear from the stockmarket eventually or at least minimise their impact in any case.
They just want to sell a positive story and you have bought this at face value.
