I'm watching GOHE and after market closed, I see this....

 

At the price of 0.03889, almost 4.5mil shares executed, $174,254.70 worth. Total volume for the day was 18mil. That's 25% position of total volume traded today. 

Can this be an institutional investor? 
Is this what marketmakers do at the end of the day for all the orders they received since market open?
