[Astex] reported a good 1st quarter and if they have three more quarters like this one, the stock, now trading at $2, should be up around 30%. Solid revenue growth for 3 straight years. Past performance does not [guarantee] future gains, but I think [Astex] is on the right track to maintain growth.
