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: CenterPoint Energy (NYSE: CNP) popped 10% in intraday trading today on news that a gas line explosion yesterday resulted in no injuries and minimal damage.

So what: A Minneapolis gas line belonging to CenterPoint exploded shortly after the stock market opened yesterday. In the past year, three separate gas line explosions have killed 14 people and destroyed dozens of homes.

Now what: An evacuation of the Minneapolis neighborhood fueled fears of a repeat of the devastation that occurred last September in San Bruno, Calif., and the stock traded down yesterday. Fortunately, CenterPoint employees extinguished the fire little more than an hour after the explosion. The stock is recovering today on news that there were no injuries and little destruction, a positive relative to other recent gas line explosions.
