Being on the New York Stock Exchange isn't exactly the mark of a great company these days..it's very volatile, and I don't think that some investors are thinking straight. It raises a point that going public may not always be the best thing for some companies.
Six Flags seems to be turning things around, but it takes time and money and they are at the mercy of the stockholders, which isn't a good thing these days.
On the delisting, this may play to SFs advantage. Seeing the parks are doing well with attendance, it maybe the leverage it needs to get things uprighted properly.
It's a bummer to see this happen, but as Shapiro said, every company is taking a major blow around now. My Disney stock is lower right now than it was when I bought it nearly four years ago!
If I had the money to invest, I'd be putting some into Six Flags right now...
