RE:where / why I'd say there are discouraged sellers. Since the stock doesn't move down despite the seliing then this means there are buyers takiing a position.
Are there 100 shares offers and buys? Somebody testing the market perhaps to see if they can accumulate? Possibly. Most of the shareholder are in a wait and see position. Since there are 300 million shares out, the trading is actually very very light. So the buyers must be very small buyers. Bigger buyers are not convinced.
