This is a penny stock. The day traders take over the stage when news comes out first because they wake up earlier than us to get on the news. Day traders get hold of massive shares and sold them at the end of the day to make their profit. 
Long-term investors can't keep up to buy the number of shares that always seem available. They were discouraged to see there was always a large number of shares for sale. This is the pitfall of penny stocks.
