Down day or up-day. Most of the float is bought up(about 75%) and only about 8M free-floating. Very few of the people holding selling which is why there is no volume. Every move is more dramatic as the liquidity is almost nil in the stock. When someone wants to buy a significant block(as today from the opening through now), the stock goes up 1.5% on just 250,000/shares. The same for someone who wants to sell a singinficant amount of 10,000 or more, stock goes down 1.5% if not more, which is why one can easily forsee a potential big downward move on almost no volume and then a quick double in the following weeks/months.
