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 fertilizer company China Green Agriculture (NYSE: CGA) slipped as much as 18% in intraday trading on heavier-than-average volume.

So what: The only new "news" out today is a press release from the company stating that "its policy is not to comment on unusual market activity or rumors." This follows a 12% drubbing that the stock took yesterday. Perhaps investors were hoping that the company would fire back after the drop with something to bolster investor confidence. If that was the case, the company's note was sorely disappointing.

Now what: Potentially more irksome for the stock was the fact that investors' primary bugaboo -- the fraud accusations against the company -- were dragged back into the fore today as multiple pundits questioned why Chinese microcap Kingtone Wirelessinfo (Nasdaq: KONE) is set to ring the Nasdaq opening bell on Monday. Why would China Green Agriculture get dragged into this? Simple: Kingtone shares its CEO with China Green. If this sounds goofy, then you probably haven't been following the comedy that is China reverse-merger companies, because this kind of oddity has come to seem like par for the course.
