I agree it's strange. Look at the trades listed right here on IHub for CSGH. So far, 266 trades and only 17 are sells. However, the price is up only 2.35%?????
These MMs also watch the fundementals of stocks. They see a big gainer downstream and often realize that they don't have any shares to sell. Then they get forced to 'trade' sellers shares for buyers and don't make a dime off of the spread. They play games to accumulate. This action could be some of that.
