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 gas engine-maker Briggs & Stratton (BGGS.Q) were cooling off today, falling as much as 13% after missing the mark in its quarterly earnings report.

So what: Briggs & Stratton said that earnings per share came in at just $0.89, below the $1.04 Wall Street expected. Revenue was also down 11.5%, to $637.3 million, and the company lowered its full-year guidance, as well. The engine manufacturer now expects EPS of just $1.16-$1.33, below estimates of $1.37. Management blamed "soft demand across international markets" for the reduced expectations. Weather was also a factor, as CEO Todd Teske said that a cold and wet start to spring delayed outdoor equipment purchases, the end market for B&S engines.

Now what: After starting out the day down 13%, shares battled back to trading just 5% by mid-day, so the market may not be seeing this as a catastrophe.  Shares are reasonably priced after the drop, and it seems like the current headwinds are just temporary. I'd like to see revenue moving in the right direction first, but I wouldn't write off Briggs & Stratton just yet.
