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 Pentair (NYSE: PNR) jumped 14% today when the company announced it would combine its business with part of Tyco (NYSE: TYC)

So what: The new company will contain Pentair and Tyco's flow control business, making a dominant force in the industry. The company will be 52.5% owned by Tyco shareholders and 47.5% owned by Pentair shareholders.

Now what: The market is reacting to a potentially strong partnership that will retain the Pentair name. Tyco is in the process of breaking itself up and this is a piece of that strategy. The all-stock deal won't be a drain on Pentair's balance sheet and it could be a boon to earnings. Pentair thinks the deal could add $0.40 per share to earnings in 2013 and $5 per share by 2015, so this may be a great buying opportunity.
