Here is something I posted last week. I think Edwin sells shares as he needs the money and I think whoever is buying is selling soon after they receive the shares, for a quick profit.
--------------------------------------------------
1. Dilution in our case is not the same as a secondary market offering.
2. Company identifies potential outside funding.
3. Company and potential outside funders agree on a price per share (typically discounted from the market value).
4. Company directs transfer agent to issue stock certificates (could take up to a week).
5. Recipient of shares then deposits those shares into a brokerage account (could take several days to get deposited and clear). Those shares are now free to be traded.
6. Recipient directs broker to sell (if they so desire).
So my feeling is that it takes some time between when Edwin decides he needs money and when the to high-volume selling occurs. Thus, there might be a disconnect of several days between dilution showing on the share structure and when the shares are sold.
Conclusion--Edwin doesn't wake up in the morning, decide he needs money, and sell shares on the market that day. Since we are getting T/A updates approximately weekly, when we see the dilution taper off, and then we see volume taper off, then we might be able to conclude dilution has stopped.
