If you can stomach major volatility not knowing whether or not you will make any money at the end of it...yes! This is not a stock. This is an ETN. You can be up 20% one minute and down 20% the next. Factors of price could include but are not limited to: War, Obama, Oil Discoveries, Dollar, The World, Space, CBS Show Cancellations, More War, Less War, and the Endangered Species List.
No amount of information you will find here is going to help you predict when to buy or sell in this stock if you don't already know why you came here. The same people who predict a price crash are married to the people who predict oil over $100 this year.
