Tiffany's: Over-expanded, brand cachet destroyed, jewelry is going to be among the toughest retail segments in the coming few years. There's very little price flexibility with the rapidly rising cost of gold, silver, and platinum. I'll look for international sales/reputation to protect this firm a bit, but barring that, Tiffany's has the potential to be among the hardest hit of the retailers, especially if they continue to open or operate stores in markets that will be crushed by the negative wealth effect of the housing market collapse.
