You said, " Management does not try to push the stock up... Infact I think that Refr does not do enough promoting. This is why the stock always goes down becuase they will not say anything for months. "
A few month ago I saw a report on REFR on CNBC and called the company to ask some technical questions regarding their product. The engineer(it was a lady) who answered my questions about the material used for Smart Window (the question was regarding the toxicity of the material, there is none) seemed quite annoyed at my phone call. I requested some literatures about the company and its product, which she said she'd be happy to send. It has been 2~3 months and I still did not get them. I even identified as a prospective investor in REFR.
Perhaps they are not interested in promoting their stock. I used the money (the portion I had set aside for REFR; 1/2 million) to buy MMCN instead, which gave me very detailed company and its product information.
I am still interested at their product, however, I was disappointed with REFR's investor relations.
