Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of luggage-maker Tumi Holdings (TUMI) fell as much as 10% today, before finishing down 6%, despite beating earnings estimates in its quarterly report.

So what: Despite solid gains in nearly every metric, investors seemed to say "not enough" to the maker of luxury travel bags and accessories. Net sales climbed 22%, while EPS was five times higher than a year ago, at $0.15 per share, and comparable store sales also grew by 11%. EPS figures beat the $0.12 that analysts had expected, and management raised adjusted EPS guidance to $0.70-$0.73, in line with expectations.

Now what: The market's reaction to the earnings news was likely a result of its high price tag, now at a P/E of 41. But, if the company maintains its current growth rate, this number will come down quickly, and the company, known for products such as a bulletproof suitcase, seems to be making a name for itself in the industry. It's also expanding quickly through new stores. For investors looking for a piece of a fast-growing company in the luxury goods industry, today's pullback presents an enticing opportunity.
