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 Tellabs (NASDAQ:TLAB) jumped 16% today after the company announced a big special dividend.

So what: The company will pay a $1 per share dividend on Dec. 21 to shareholders of record on Dec. 14. The company also said that Interim CEO Daniel Kelly has been given the job permanently.

Now what: A big dividend is great for shareholders, but the reaction is a little overdone. The stock is up $0.48 as I'm writing, nearly half of the dividend that will be awarded. This may be a buying opportunity between now and the ex-div date, but I don't think it is at the current price. The market has overreacted wildly to these special dividends in recent weeks and many stocks have fallen after the euphoria wore off.
