The energy debate rages on as oil and gas futures bounce around with 30% corrections. Which side of the energy debate are you on? Bears say that oil and gas prices are coming back down to earth. Speculators and hedge funds bid them up, global demand is slowing and alternative forms of energy will soon replace the fossil fuels we've come to depend upon. Bulls argue that oil and gas supplies are dwindling at the same time that the emerging market economies (China, India, Brazil and 20 others) need more. As their middle class population builds they too will want cars, air conditioning and electricity and demand will increase. Most oil reserves are in countries with unstable governments and when geopolitical events get ugly, prices tend to skyrocket.

I'm a long term energy bull -- 10% of my money has been in energy stocks for the last several years and today I maintain that allocation for two reasons. First, I believe in five years, oil and gas prices will be higher than they are today. Second, owning energy is a great hedge against other asset classes like stocks, the US dollar, and inflation.

No one knows which way energy prices will go next week or month so I continually rebalance my portfolio. As my energy stocks rise, I trim them and when they fall, I add to them. If my portfolio goes to 12% energy, I sell them back down to 10% and vice versa.

Now comes the easiest part – which stocks do I pick? Easy you say? Yes – because I don't worry about stock picking due to a miraculous new invention I'll discuss below. I own three energy stocks: the U.S. Oil & Gas Exploration & Production Index (NYSE:IEO), the U.S. Oil Equipment & Services Index (NYSE:IEZ), and S&P Global Energy (NYSE:IXC). Through these three stocks, I own about 200 energy stocks in precise allocation percentages to parts of the energy sector, weighted according to my own preferences – 60% is in IEO, 30% is in IEZ and 10% is in IXC. Why pick stocks when I can own them all? Here's what I mean.
