I agree with the lack of response on good news. But I believe they sold those shares that they registered there in the first days after the announcement. We will know on the next earnings report, but that is a long wait with no price action on the stock. 2225 shares sold in the first 1/2 hour of trading today, What's up with that? I am guessing that a large move is happening here shortly and I hope it is to the upside for a break out.
Since the semi-annual report in mid-March, I count 12 positive announcements related to ROSG. This includes patents, new tests, up-grades and partnerships. Since then, share price has moved up about 40 cents (3.30 to 3.70). Granted, none of the announcements had any dollar amounts associated with them, but still, it seems like anything positive is being significantly discounted. At about 3.3 cents average per "positive" it would seem we're in for a long wait until we get back to the last secondary price.
What would help? If management announced that all of the shares they had planned to sell on the open market (to fund continuing operations) had been sold. Without that overhang, perhaps investors would see it as the bottom is in.
