Agree One up...at 18.5 cents it was worth a look for a medium-long term hold based on growing revenues and turning of profits.
But don't forgot this company's revenues come from retails outlets and sales of rather simple manufactured devises such as solar water pumps and licensing of hot water systems. All of these revenue streams would allow easier entry by competitors...so they future is not a simple as "its solar and its going to boom." There are many other solar water heaters going around and those pumps could be easily copied in China.
Not sure what happened in Germany to spark this interest...maybe its just one instititional taking large long-term stake and the rest is hype. Look how many posts on HC there were in the six months before yesterday...4...so not many people have been following this stock long-term.
I think some degree of caution is required if you are playing this stock for a short-term gain...suppose its a question of how long they will keep buying in Germany.
