Well in that case, we've been discussing that here for quite a while. There was a conversion of a conv. dibenture last summer (at .0006 I believe), and many of us believe they have not bled all of them in. They weren't all necessarily dumped into the float last few rounds of upward movement since their conversion.
Many, or few could have been absorbed with the volume, or they could have just been manipulating it the whole time.
Clearly there is a big shareholder that puts shares out to be sold at will, however, they seem to have enjoyed pulling their orders at key supports and letting it move up again.
Company has net cash from first quarter alone, so increasing the O/S is an unlikely scenario. It's not dilution, imo. The amount of "active" shares trading in the float, however, is a different argument
