If you look back a little more than a year ago, you'll see this went to .40 from about .07 in a fairly short time. The .07 was due to peeps selling .02 shares that got issued for IR services as I recall. The .40 came from a few groups on ihub who became aware of the company and decided to buy in. At the time, we were under the impression that commercialization would begin first half of 2010. So you are correct that it doesn't take "official" information to affect the sp. However, it does take official information to sustain it, and to get it going, there must at least be anticipation that better things are imminent.
I personally think that all will be well in a few weeks. I believe those selling have a calendar deadline to be done this year, and once they stop, the trend will reverse, which will bring back the swing traders. Knowing the Mammoth funding is out there coupled with a little good news of progress will cause a really nice run for those here to enjoy it. The time to buy is now if you don't already have what you want.
