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 network company F5 Networks (Nasdaq: FFIV) fell 11% today after the company's earnings beat expectations.

So what: Wait a second -- it beat expectations and shares are down? Yes, revenue was only in line with estimates at $290.7 million and fed fears that the company's growth may be slowing.

Now what: If you prefer to look at the bottom line, earnings per share of $0.97 after one-time items beat estimates by $0.06. I think the market is overreacting here, and for those long-term investors looking for a chance to buy in, this is a great opportunity. Management is expecting continued sales growth next quarter, and F5 is still solidly profitable.
