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 Chinese meat processor Zhongpin (Nasdaq: HOGS) are stinking up the place today, falling as much as 13.2% on modest trading volume.

So what: Zhongpin has no news to report today, nor are we hearing market-changing reports on the Chinese economy. Country Style Cooking (NYSE: CCSC) and other regional sector peers are holding steady today.

Now what: Chalk this one up to "just another movement," folks. Trading was very light until the shares fell far enough to be newsworthy for that very reason, and nothing has changed in the company, around it, or for business prospects ahead. Zhongpin is busy borrowing money to expand faster, which is a turn-on for some investors and a warning sign for others. With a PEG ratio just north of 0.5, there seems to be more risk than reward priced into the stock right now.
