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 Canadian electric utility CH Energy (NYSE: CHG) surged 13% today after the company agreed to be purchased by Fortis for what amounts to $65 per share.

So what: The deal, which is expected to close by early next year, will involve no layoffs assuming CH Energy shareholders approve it. Fortis has agreed to assume $500 million worth of CH Energy's debt.

Now what: It's always odd when the purchaser trades above the potential buyout price. Currently at $66.15, there's almost a 2% premium to Fortis' buyout offer, which sometimes implies the potential for a bidding war. I personally don't see that happening and think shareholders might be getting a bit overanxious at this level. With little upside left in the stock, I'd say it might be time to let this one go.
