It's quite simple really. They sold a truckload of shares really cheap to institutions. The mm's run up the price so those same institutions can sell their really cheap shares at really high price to retail buyers. When all the shares are unloaded, this goes back to 6 or below. Happens all the time. Pretty much all those shares purchased by the institutions have been sold to unsuspecting retail buyers. Everyone is happy except for the ones who paid a 50% premium for this highly risky stock.
