Here is what i think happens during the afterhours. Someone puts in an order to sell with no limit and then follows with an order to buy at 3$ and bingo you have a 5 dollar stock selling 100 shares for 3 dollars. This shows up as stock going down 2$. The purpose of this shenanigan is to make people think the stock is tanking and so the next day they put their shares up for whatever they think they can get with no lower limit and the wolf sweeps in and buys it up. I don't know that if this is what happens but, something goes on here and I wish someone smarter than me would explain what is happening.
agree, some one trying to lower the pps so that they can pick up more tomorrow, well before Jan. earnings report which may propel the stock up. i wouldn't worry about 200 shares signifying any thing other than your stated theory.
