"Prices for energy stocks, including the drillers, are bombed-out and should be aggressively accumulated now," says resource expert Eric Roseman.

Here, the editor of The Commodity Trend Alert explains, "The absolute worst thing we can do is sell now." Here's his outlook on energy and drilling and a trio of buys.

"The pain felt by commodity bulls should abate shortly; this mind-blowing expansion of credit will ultimately fuel inflation to much higher levels. Eventually, long-term interest rates will rise sharply in the United States as the government grows hungrier to finance its out-of-control spending habits.

"What we're seeing now is a market that has gone from being obsessed with inflation just two months ago to one now worried about rapid deflation or an environment of declining prices. Combined with bad economic news overseas, the U.S. dollar has seen a violent reversal exacerbating the plunge in raw materials. It's been a brutal sell-off and the worst decline I've seen since mid-2006.

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.

Jim Farrish, founder of Money Strategies, is a leading expert on sector investing; his approach combines technical and fundamental analysis within the framework of investor psychology.

In the latest from his SectorExchange.com, he says, "This week's spotlight is the energy sector with a focus on the current trend, what the outlook is and what strategy to take looking forward." Here's his latest, along with some ETFs to play this trend.

"Over the last six weeks, the financial media has warned that 'consumption will decline as a result of the US recession.' But so far we have not seen any slowdown in consumption and may not based on recent studies.

"In fact, we have seen China and India absorb any lack of consumption by the US. The key here is not so much who is right and who is wrong, but how you manage your own positions within the energy sector.

If you don't yet own oil-services stocks, commodity and resource expert Eric Roseman says "You better. I'm expecting big returns for everything energy-related in 2007."

In his Commodity Trend Alert, he states, "Whatever you do, hang on to your energy investments. By the end of this year, you'll be lighting firecrackers on New Year's Eve. I'm that sure." Here, he looks at some of his favorites, which he consider "must own" oil service plays.

The advisor notes that corrections for the energy complex occur in every bull market, and that the most recent one is no different. However, he notes, "What's incredible is how bearish sentiment had become for oil since earlier this month; just six months ago, analysts and traders were forecasting $100 per barrel by spring. They then began to forecast $40!"

Roseman, however, has remained bullish through the correction and notes, "In addition to tight supplies, still at 86 million barrels of oil per day against 84.5 million barrels consumed."
