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 recreational products company Brunswick (NYSE:BC) popped as much as 11% after reporting its fourth-quarter earnings results.

So what: It was a mixed quarter for Brunswick, which recorded a 9% rise in revenue to $829.8 million as it squeaked by with a $0.02 profit. Relative to Wall Street's estimates, the company was shy by more than $19 million in sales but eclipsed the consensus EPS estimate of a loss of $0.07 by a wide margin. Furthermore, Brunswick's 2013 guidance calls for EPS in the range of $2.20-$2.45 and revenue to increase by 3%-5%. Wall Street's current estimates are for EPS of $2.24 on a 1% improvement in revenue.

Now what: Even with an in-line estimate for 2013, I still can't say I'm particularly excited about Brunswick's prospects. Domestically, higher taxes on upper-income earners are going to drag on boat purchases for which Brunswick is a major parts and accessories supplier. In addition, Europe is in little shape to mount a comeback and will continue to drag on Brunswick's results. Based on its latest rally, I'd call shares more than fully valued here.
