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 food manufacturer Treehouse Foods (NYSE: THS) fell 10% today after the company gave weak earnings guidance for the fourth quarter.

So what: Management said it expects revenue to grow about 5% to $535 million and adjusted earnings per share to be between $0.84 and $0.87. Analysts had expected revenue to be $567.1 million and earnings to be $1.07 per share.  

Now what: The company said warm weather hurts sales of hot cereals and soups that normally sell well in the winter. Also, a higher percentage of sales to lower-margin dollar stores is having an impact on profitability. A miss like this isn't good news, but these seem like temporary problems due to very unusual weather so I think the sell-off may be a bit overdone today.
