I came across this for you AG players:

Over the last two days, a group of us have been following Origin Agritech Limited (SEED), AgFeed Industries, Inc. (FEED), and Agria Corporation (GRO), among others. The moves have been big and fast, and I missed them, although some of my counterparts did not. I classify these as bull riding stocks: They are hard to get on at first, but thrill overtakes you immediately when you grab on. The trick with these is to hold on tight for a wild, bumpy, and exciting ride, and only hold on long enough to be a winner. If you hold on too long, you will surely be tossed to the ground, and stomped or gored. There are plenty of clowns on Wall Street, but none that will save you.
