•Six Flags. (SIX) The amusement park operator defaulted on debt on June 24, S&P says, just ahead of the critical summer vacation season. Six Flags shares are down 44% this year. Meanwhile, rival Cedar Fair's (FUN) results have exceeded expectations, and its stock is up 6%.

So far, benefits to Cedar Fair have been indirect, says James Hardiman, analyst at FTN Midwest Securities. In some parts of the country where Six Flags and Cedar Fair compete directly, such as California and the Washington, D.C., area, Cedar Fair may benefit by being better able to afford promotion, he says.

Cedar Fair also benefited indirectly by buying Geauga Lake, a park near its Cedar Point park in Sandusky, Ohio, from Six Flags in 2007 and closing the amusement park portion in time for summer. Plus, it's unlikely Six Flags can afford to lure visitors by building the same jaw-dropping rides Cedar Fair can, he says. "The gap with Six Flags will only widen," Hardiman says....

^^The building rides part may be true, however, a.) SF already built a gluttony of rides in the early and mid-90's anyway, and b.) SF deals are far better than what CF provides!!

Interesting article. In this economy and market for your stock to have done 6% is a very good sign. Most companies and the overall index are down.
