Well, if one does not, like Under Armor who skipped ICR XChange conference this year, rumors will go out. Quote StreetInsider “Under Armour (UA) Sinks On Fears Of Back-End Weighted ’08 Earnings”
January 17, 2008 11:01 AM EST Shares of Under Armour, Inc. (NYSE: UA) are under heavy pressure this morning which is being attributed to comments from Wachovia from the ICR Xchange about the company’s 1st-half 2008 marketing spend and back-end weighted 2008 earnings growth.
The firm said, “While UA is not presenting at the conference, we have learned that the company is planning to run a 60-second Super Bowl advertisement, and believe 1H08 marketing expenses relating to the launch of the cross trainer footwear product could cause 2008 earnings growth to be significantly back-end weighted. We believe total marketing spend for 2008 will be in the 12%-13% range, but a disproportionate amount could come in 1Q08.”
Oh, boy, why did you try to hide from investors (analysts), Kevin. You see even beaten down guys like Crocs and Heelys are there 
Seriously, I think Under Armor has the most to lose in the slowdown of US consumer, because their sales is much more concentrated in the US (the football or baseball gears).
