Over the long run yes. But if you are able to trade in an out over a short period of time sucessfully, BOIL and UGAZ can make you some much quicker profits. These ETF's make great temporary hedges when you think UNG is in oversold territory. Just sell em on a big pop and book profits. So can GASL if your thinking nat gas related companies are underpriced. Just be careful when the market is overbought, because when the market goes down, most companies are drug down with it.
