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 bookseller Barnes & Noble (NYSE: BKS) were bound in red today as they slipped as much as 15% in intraday trading after the company announced fiscal third-quarter results.

So what: In the expectations game, B&N was a loser this quarter. Though earnings per share of $1.00 were within the company's guidance range of $0.90 to $1.20, it was well short of the $1.13 that Wall Street was looking for. Revenue of $2.3 billion was also slightly softer than expected. But the disappointments only started there.

The company also announced that it's suspending its dividend, a move that investors can't be happy about, particularly as more investors are looking to dividends to fuel their portfolios. And we all know how much investors like guidance, right? Well, B&N isn't giving any. Thanks to the Borders (NYSE: BGP) bankruptcy, B&N decided that it'd hold off issuing guidance for now.

Now what: I'm getting a picture of Ice-T running madly through the woods, trying his best to survive in the classic B-movie Surviving the Game. You're obviously rooting for him, but the odds are heavily stacked against him. For B&N, it's got its Nook e-book reader and, though still unprofitable, B&N's website is at least growing quickly. But (Nasdaq: AMZN) will continue to bear down on the bookseller, both on the book front and the e-reader front -- where Kindle dominates with a 67% market share. And it will increasingly have to battle Apple (Nasdaq: AAPL) as well, as the iPad is a competitor to the Nook and the company's e-bookstore has already grabbed a 9% share of the e-book market.

In the end, Ice-T made it. You kind of knew that would happen because it's Ice-T and he's generally a tough so-and-so. But this isn't a movie, and though I'm not calling for the disappearance of B&N, I'm also not betting on a shining future.
