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 casino operator Caesars Entertainment (NASDAQ:CZR) jumped 10% today, when the company announced a new CFO.

So what: The company appointed Donald Colvin, an executive from Nevada utility NV Energy, as its new CFO and executive vice president. Seriously, that's all that happened.

Now what: There's no reason to buy Caesars on this news, unless Colvin has a way to rid the company of $20 billion of debt. What may be lost in the jump later in the day is that Caesars hit an all-time low early in the day today, showing how little confidence investors have in the long-term trajectory of the company. I'm definitely not a buyer here, and certainly don't think a new CFO changes the investment thesis in Caesars.
