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 Olin (NYSE: OLN) fell as much as 10% after reporting better-than-expected earnings. What gives? I've got no idea. All I see is good news.

So what: Digging into the numbers, Olin said revenue from its chlor-alkali business for producing detergents and bleaches (among other things) rose 47%. Overall revenue improved 30% to $529.1 million, while profit more than doubled to $0.52 a share. Analysts were expecting $498.8 million and $0.50 a share, respectively.

Now what: If there's a problem with this five-star stock -- and I'm not saying there is -- it's that dividend growth has gone nowhere over the past five years. Is that enough to keep you out of this stock? Did you sell today? Let us know what you think using the comments box below.
