Hmm.
I hear your frustration. I have taken a 25% hit on ZVTK right now (I am trying to look at the bright side of this - a lot of stocks went down 30-40% in one day this past week. We took a 25% loss over the entire week. Some of my BIG BOARD stocks are down 10-15%).
That, to me, shows a lot of RESISTANCE to decline by interested investors.
Engel seems to care about his investors too. He has been answering their emails, taking their phone calls...and he has got to have more important things to do with all of the negotiations for TV time and selling mass quantities of bulbs.
-------
Note that he has been putting out PRs on a regular basis denoting IMPORTANT events (like starting the new ad campaign, going from Pinks to OTCC). I have heard the word "fluff," but those aren't fluff - they are significant improvements in this company at this early stage. I WANT to know those things. So do the other investors.
I am also sure that he has some concern about the stock price, but probably not as much as you might think - since he is the one in the driver's seat. He KNOWS if this stock is going places or not. He KNOWS the sales figures.
If you are really concerned with this, I recommend sending him an email. If you do it in a professional manner, I would think he would respond.
My guess is that he would wait for a significant milestone before announcing a sales figure - like 30 full days or the end of January.
