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 Capstone Turbine (CPST) dropped as much as 11% today after reporting fiscal fourth-quarter earnings.

So what: Revenue rose 18% from a year ago, to $35.4 million, and the company lost $4.1 million, or $0.01 per share, in the quarter. Revenue was slightly lower than estimates, and earnings per share were even with expectations. 

Now what: The only other note is that Ardour Capital downgraded the stock to hold, but I don't see anything alarming in the quarter. Capstone is making progress on its way to profitability, and next year may be the year it turns the corner. No reason to change your investment thesis today, although this Fool is waiting to see a positive bottom line before buying in.
