Wow, the price moved UP with massive volume on 12/4/09.
Pretty typical of a pump and dump actually. Short selling would have lowered the price with that sort of volume.

I wonder if it was the spencers selling. As you point out, it's virtually the entire O/S at the time, so it had to be insiders or some massive turnover of the float. That's almost $1 million/day in shares traded for 6 days in a row. Someone made a boatload of money and someone, or more likely a number of people lost a ton.
