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 Harman International (NYSE: HAR) rose 10% in early trading after announcing earnings and a big order.

So what: Fiscal-third-quarter revenue rose 16% to $1.09 billion, and earnings per share were $0.74. Analysts had expected $1.03 billion in revenue and $0.67 in earnings per share. The company also won a $2 billion contract from its largest customer, BMW.

Now what: The excitement that investors had early this morning wore off, and shares are now up just 4% on the day. The earnings beat is really a bigger deal than the BMW order right now because the order won't go into production until 2014. It does, however, give Harman a little assurance for the long-term that its biggest customer is still on board. I like shares at this point because they're trading at just 13 times forward earnings and the company is on a solid growth path.
