I could be naive, but it looks like someone waited until mom and dad left the house at 15.30 and then began to pound the stock down on low(er) volume.

It definitely looks like it was a calculated move to force the share price to support levels and rake in the shares as the stop-loss orders were hit. Monday will tell us if they did enough technical damage to drop us down through $3, but I don't think that is the case. I'm pretty sure the bottom is in. Of course, that and $2 will buy you a cup of coffee at Starbucks...
