"We sense a turn for the better coming in the oil sector," says Peter Way who tracks 'big money' investors for his Block Trader Oil & Gas Report. Here's his look at the "big block" traders.

"When we use the hedging analysis employed in our stock price forecasts, there are significant differences between some adjacent futures expirations. Here's the current picture:

"Front month (November) hedging suggests likely near-term higher prices. But the December contracts are likely to continue the past 3-month price decline – briefly.

"After that we could see crude rise over a few months into the $115-125 area or even higher, providing a bullish backdrop for most energy stocks. We sense a turn for the better coming in this sector.

"Several issues are selling at attractive prices now. Among major integrated producers, the standout prospect among the big oils is Petrochina (NYSE: PTR).

The Block Traders' Oil & Gold Monitor is a unique newsletter that focuses on big block trading activity by institutional buyers. Through a sophisticated analysis of market maker hedge positions, editor Peter Way determines forecasted gains for specific sectors and stocks. Here, he looks at some current market maker favorites in the oil & gas industry.

Peter Way explains, "The reality for crude oil price expectations are reflected by hedging on some $85 billion of crude oil future contracts. Every month in 2008 sees enough likelihood of prices at $80 and above to cause a brisk business in insurance at those levels. In short, the crude oil price picture is one of stability to strength from high levels. As with any natural resource, it's always safer to bet on shortage than oversupply."

Looking at big market maker activity in individual stocks and stocks, the advisor adds, "The value buildup in Exploration & Production companies is clearly already under way and is likely to continue. Expect to see E&P companies acquired by the major integrated companies. Expect to see Oilfield Services companies kept very busy as supply continuity issues grow more severe."

In his Block Trader Oil & Gas, Peter Way follows the big hedge funds and market makers to find out what they are doing. Here's a look at his top oil plays.

He observes, "The hedgers at the NYMEX are protecting their crude oil positions in ways that indicate they see continuing upward pressure on prices."

Based on this hedging activity, he states, "The outlook for the next 12 expiration months that the by major players at the crude oil table suggest little lasting price weakness, and a general level prevailing above $70 over the remainder of the year."

What are the best stocks to buy to bet on the trend for firm oil prices? To decide, Peter Way looks at the buying patterns of market makers -- the big boys on the trading floor.

From their positions, he notes, "Among the large oil producers, China's CNOOC, Ltd. (NYSE: CEO), Canadian Natural Resources, Ltd. (NYSE: CNQ), and Suncor Energy (NYSE: SU) all combine historically strong odds and payoffs."

In addition, he notes positive market maker activity among oil exploration & production stocks. He explains, "With significant quantities of low-cost reserves already found, and prospects for additional finds tied up, these companies inevitably will get acquired by bigger producers whose customer demands exceed their yearly reserve findings."

For many, he says, it's just a matter of time. Notable stocks in the stock, he adds, are Holly Corp. (NYSE: HOC), Carrizo Oil & Gas (NASDAQ: CRZO), Range Resources (NYSE: RRC), Southwest Energy (NYSE: SWN), Ultra Petroleum (NYSE: UPL), and Talisman Energy (NYSE: TLM).
