It seems like Capstone has some great growth potential, and it is only a matter of time before it rises. Green energy is on the rise thanks to huge oil prices and people trying to find solutions to rising energy costs, and as an article on StockHouse.com states, it will only take one piece of good news to have this stock climb to its real potential. Recently, Lazard's analysts have put a buy rating on CPST with a $6 potential price tag on it (a 50% growth rating isn't too shabby at all), and CPST has been on a steady increase for the last few months. I would definitely recommend checking out this article on StockHouse.com which is all about CPST's potential success.
