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: China MediaExpress (Nasdaq: CCME) shares jumped 10% early Monday after the company released earnings.

So what: Revenue was up 118% to $57.0 million and net income increased by 167% to $31.1 million, as China's appetite for advertising grows. Great headline numbers but earnings per share increased only 44.6% as the diluted share count nearly doubled.

Now what: Traction in its inter-city bus network accounted for most of the company's growth as the network expanded during the quarter. I like what China MediaExpress is doing, and with a price/earnings ratio below 10 and $170 million of cash on hand, the company is in solid value range. I am concerned, however, about the increasing share count -- I will sit out this stock run and wait for a better entry point when the stock cools off.
