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 restaurant operator Brinker International (NYSE: EAT) climbed as high as 11% on Monday after the company's quarterly results topped Wall Street expectations.

So what: Brinker's third-quarter profit jumped 12% as increased traffic boosted same-store sales, prompting analysts to increase their growth expectations on the stock. Smaller fast-casual chains like Chipotle Mexican Grill and Panera have taken a big bite out of Brinker's market share in recent years, but today's results suggest that its Chili's and Maggiano's franchises are at least starting to hold some ground.

Now what: Based on the recent positive sales, traffic growth, and cost improvements, management reaffirmed its longer-term profit goals. "These factors combined with returning value to shareholders through share repurchases make us confident we'll deliver on our promise to double EPS by 2015 to $2.75 to $2.80." Of course, with the stock setting a new 52-week high today -- up about 50% from its September lows -- much of that optimism might already be baked into the price.
