I was also impressed by Friday's action. Watch SBSH on level 2's. At times they create the smallest of spreads, I think to drive selling at the bid, which is where a buyback needs to happen.
Also, at one point yesterday, when price drops were about to take us below 3 cents, SBSH jumped the bid size up to a huge number. Often, these tricks are fakeouts, but nonetheless, it encourages a big seller that there is an available buyer for a big dump. They would not of done this otherwise, as it also halts a price crash if their only motive was to tank the stock.
