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 Vantage Drilling (AMEX: VTG) fell 10% briefly today when the stock ran out of steam from its long run higher.

So what: Shares have been rocketing higher on a bunch of good news recently, and it looks like the rally is just running out of steam. Yesterday, the company even released news of a drilling contract in Southeast Asia worth $77.9 million, so it doesn't look like time to panic.

Now what: I really don't see anything but positive news coming out of Vantage lately, so this could just be the pullback I was waiting for when shares bounced on Monday. Director Su Hsin-Chi has even been buying millions of shares, showing support for the company from insiders. A pullback like this is pretty normal after the run Vantage has been on and could be viewed as a buying opportunity for investors looking to jump in.
