Re: "If you were trying to dump your shares, this would be a way to manipulate the SP to keep S/P up while you dumped your shares."

I agree.

I just did simple calculations on the last 30 trades. Trades made that were under the average price amounted to 7150 shares per trade (on average). Trades that were for more than the average price amounted to 2565 shares each on average. I think a more refined analysis of trades would show even more evidence of manipulation intend to keep the price up while someone unloads.
