PureCircle is the dominant player in the Stevia space, globally, as that's all they do and they have a business to scale to the size required by the Coke's of the world. But their share price has more than caught up with their mid-term potential IMO. I still haven't sold my position, but then I tend to hold shares a very long time (5+ years). I think there is still great long-term upside if you have the patience.
Other Stevia plays you might want to check out are S&W Seed (SANW on NASDAQ) and Evolva (EVE on the Swiss Exchange). There are likely more, but those are the two I know & follow (but don't have a position in).
Good luck to you.
