Despite its phenomenal growth, the Vietnamese stock market remains small in many ways. This is in part what allowed a Vietnamese trader to manipulate stock prices recently. In fact, between September 1, 2015, and May 13, 2016, Do Thi Cam Thuy used 29 different trading account in order to manipulate SPI shares prices. Fortunately, the fraud was found and she was fined $26,000 for civil fine and an additional $408,000 worth of profits she made by manipulating SPI share prices. Even though this may, at first glance, sound like a worrying news, there are two important things to consider. The first one is that that kind of action has no impact for a long-term investor, and the second one is that this illustrates the good job the State Security Commission of Vietnam is doing fighting fraud.
