The previous article along with the fact that they have lowered their operating costs from several millions to hundreds of thousands, patched up a law suit they were involved in, raised 150,000 euros, have a new CEO or president (i think), and a presence in China since 2012, or earlier, when they shipped 50 drive systems to first auto works for 200,000 dollars, also helps in solidifying this company. I believe the large jumps in share price can be attributed to large investors realizing the potential here and taking interest. Also, Enova is listed as competition to UQM which means they are a competitive force in the electric vehicle industry. And as was previously mentioned UQM has also seen a nice rise in share price....I like it, I like it alot.
