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 medical device company Insulet (Nasdaq: PODD) rose 14% today after the company released earnings.

So what: Revenue jumped 75% to $44.6 million, and loss per share dropped a penny to $0.29. Both results were worse than analysts were expecting, as was revenue guidance of $150 million to $154 million.

Now what: The losses keep mounting and for the full year. Insulet is expecting an operating loss of $39 million to $42 million. I just can't get excited about a company posting losses as far as the eye can see, no matter how fast revenue is growing. I'm going to stay away from this move today, and Insulet can wake me when it actually starts turning a profit.
