You are comparing two different sectors - consumer/mobile tech is characterised by fast money and fast results. Green tech and bio tech are characterised by slow money and slow results.

Green tech can become fast money once it's commercially ready, and has a pipeline of potential contracts which in turn becomes a pipeline of announcements to excite the market, drive up demand and SP.

One of the other companies you had previously mentioned, LER, is at the opposite end of the spectrum. I have known the company for over two years and know Ken the CEO quite well. They have great (potential) technology but there are many steps still required to validate it in a commercial sense. They have had 3 rights issues in that time and the can gets kicked further down the street. Because of this the announcements are few and far between and the SP has not gone as crazy as it should have. They are stuck in the slow money cycle. Emefcy looks to be ready to be a fast money stock from launch.
