Jarvis, IMO April & May's PR's added a slew of new investors who believed, based on PR's, that STEH was about to land a major revenue deal and would therefore blast off (STEH was heavily touted to expect a ride to .75-$1.00). Once the "agreement" was released a lot of the stock got dumped (buy on rumor sell on news, penny market manipulation, and/or pump & dump strategy whichever you choose to believe).
We've seen a bit of the same action the last few weeks. A little bit of news, and a few PR's pumped the stock up a bit to the mid .20's. However, IMO, since we still haven't "seen" substantial revenue coming in, or a 2nd contract signed (after almost 3 months, how long does Universal need to test?), or the company reporting yet (hopefully VERY soon) the stock's being sold off again. IMHO, unfortunately, the stock will not go back to the hyped up June .30's-.40's until we SEE some "substantial" revenue and/or 2 contract.
