I have to tell you, information filters down in EVERY company. In this case I think we experienced "market jitters" and this is occurring prior to earnings to all stocks, just at different levels. Hope smart investors added to their positions.
I don't think I'd say "usually." There's been some nice earnings surprises in the retail sector lately. I see WSM as a good, long-term investment as they're one of the strongest retailers out there right now.
