Leveraged ETFs for Long Term Trading

In practice you cannot afford ever to have a margin call because it will force you to sell out at a low essentially. That means restricting the amount of leverage you take and in fact you probably want it to be half or less than the theoretical maximum you think you could take. Another decent option for leverage particularly for somebody that's holding something long term are the wisdom tree funds which are moderately levered. The most popular one for gold I know is called UGL.
