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 if Inergy (NYSE: NRGY) are up 17% today after the company agreed to sell its retail propane business to Suburban Propane (NYSE: SPH) for $1.8 billion.

So what: Inergy will get $200 million in cash, $600 million in common units, and up to $1 billion in senior notes for the business. Shareholders will get their corresponding share of 13.7 million common units of Suburban following their registration with regulators.

Now what: Inergy's market cap is still just $2.5 billion after the deal, and this will give the company a chance to pay down some debt if it chose to. I am also concerned about what the loss of 600,000 customers will mean to future earnings and the company's dividend payout. I'll take a wait-and-see approach to the stock because I would like to see what the direct impact will be and what management will do with the money.
