"Peabody Energy (NYSE: BTU), the largest private market coal firm in the world, had a great 2008," says Jack Adamo who has recently added the stock to the buy list of Insiders Plus.

"Peabody has extensive holdings in the U.S. and Australia, the latter serving the China/Asia Pacific markets. It sells steam coal for heating and utility use, and coking coal for steel making.

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."
