it's a good question and there are many possible answers. First and most likely is that there is not enough exposure for the stock and it needs to be put on more peoples'/institutions' radar. Even though the press releases are a good start, the company can do something about this though to increase its exposure.
Oh, in addition, why it isn't holding .10; my take is that players who were only in it for a pop based on the orphan designation announcement are getting out now that they see that the stock hasn't yet cleared any previous resistances. It's understandable since their reasoning for entering their position did not yield the result they were looking for. Makes sense on their time frame. Personally though I feel that since there is no fundamental change to the company, there is no reason to exit if you have a long term horizon.
