"Oil had a good year in 2010, rising 15 percent, and 2011 looks to be even better, as a stronger global economy pushes demand for resources higher," says Stephen Leeb.

The editor of The Complete Investor explains, "Oil service and equipment companies are the most leveraged way to play rising oil prices. Here's a look a Schlumberger (SLB) and National Oilwell Varco (NOV).

"First is Schlumberger, operating in more than 80 countries. The company is the world's leading supplier of energy technology, project management, and information solutions.

Oil is no longer flowing from the Deep Horizon well into the Gulf of Mexico, and investors are starting to take another look at the oil industry.

One oil stock that is standing out right now is Cameron International (CAM), which provides drilling systems and equipment -- like the now infamous blowout preventers.

Goldman Sachs just upgraded Cameron to a Buy rating and added the stock to its Conviction Buy List saying, "we expect Cameron to be one of the key beneficiaries of any renewed focus on oil services."

TheStreet.com's Jim Cramer says the stocks like to move higher along well-worn paths.

With the usual suspects rallying -- gold and oil -- it's important to remember how the oil rallies have unfolded in the past. You have to be able to recall the oil pecking order of the petroleum complex ramp.

First to move in the drilling complex is Transocean (RIG) (Cramer's Take), the wildest trader in the group. Then it is National Oilwell Varco (NOV) (Cramer's Take). Forget that both of these are the least affected by the day-to-day price of oil. The market's real stupid on these oil moves, and that's what happens. On the oil side it is Occidental (OXY) (Cramer's Take), which at least is closely correlated and can have a big move throughout the day.

"National Oilwell Varco (NYSE: NOV), a buy in our 'Wildcatters portfolio,' will see an outsized benefit from improving conditions in the global oil market," says Elliott Gue in The Energy Strategist.

"Rig technology is the crown jewel of National Oilwell's business; the unit builds key equipment used on land and offshore drilling rigs.

"The unit is currently benefiting from the boom in deepwater drilling activity -- one of the only drilling markets that continue to see growth.

"Equipment used on deepwater drilling rigs is far more complex and expensive than that used on land or shallow-water rigs. As a result, selling equipment into the deepwater market carries far higher profit margins for National.

"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).

• Collins Stewart downgraded Lloyds TSB Group (NYSE: LYG) to Hold from Buy following the acquisition of HBOS (OTC: HBOOY) as they expect short-term weakness in the stock.

TheStreet.com's Jim Cramer says the oil stocks' decline yesterday was exacerbated by a hedge fund's collapse.

"I think the collapse in the commodity stocks shows a worldwide recession."

"The decline in oil and oil service stocks, far more severe than the decline in the commodity, bodes for $80 oil and gas."

"Without a hurricane hitting rigs, the companies involved in the servicing and maintaining rigs will have severe earnings declines, at least according to their stocks."

These are three perfectly acceptable analyses of the action in the Oil Services HOLDRs (AMEX: OIH) (Cramer's Take) and in the oils in general yesterday in light of Gustav's failure to do any real damage and a continued expectation that economies around the world are slowing.

It's just that they are false takeaways. The single most material issue for the stocks -- not the companies -- was the collapse of Ospraie Management, which blew up and got blown out and took a ton of stocks down with it. The fact that this market is thin, that lots of players clearly knew this blowup was coming, and that the fund was no doubt leveraged up the wazoo (as all desperate managers tend to be) exacerbated the declines perhaps two- or threefold.

TheStreet.com's Jim Cramer says there's a big disconnect between the trade, orchestrated by the funds, and the real-world demand.

How can anyone actually own oil or natural gas through this relentless assault on price? I know when it was going up, the talk was that all of these new funds were indexing trillions to commodities and it was just going to stay there, and that's why there was a new level of oil demand.

Can those same accounts come in every day and take this relentless pasting no matter what the news? And do they believe the news, that they are losing money today because some storm went to Daytona and not to New Orleans?

Yesterday, I had Jim Hackett, the CEO of Anadarko Pete (NYSE: APC) (Cramer's Take) on "Mad Money at the Half," and he was flabbergasted at the activity in the futures pit and how unrealistic it has become. He's focused on natural gas, where he says the demand at $8 by industry -- the glass makers and chemical companies and steel and aluminum users -- is voracious. But the futures themselves just keep going down, regardless of the demand.

TheStreet.com's Jim Cramer says don't blame the currency, it's all about supply and demand.

The dollar.

How often do we hear that this currency as the culprit of the m.o. of everything that the "sophisticated" types think is happening. It is almost conspiratorial:

• the Fed raises rates;
• commodity prices come in because they are a hedge against the weak dollar;
• oil fluctuates in price because of the dollar;
• the dollar controls stocks and bonds.

I am not an unsophisticated player. I recognize that the dollar has some importance when investing in strong currency countries and when the translation to the dollar occurs, a la the amazing results in a company like a Eli Lilly (NYSE: LLY) (Cramer's Take) or a Schering-Plough (NYSE: SGP) (Cramer's Take) or a H.J. Heinz (NYSE: HNZ) (Cramer's Take).

But the dollar and oil? Okay, I hear the intellectuals, but how about the empiricals: oil went from $119 to $148 while the dollar was steady against the Euro. Do the facts matter? What happens if they get in the way of the intellectuals' stories.

MOST NOTEWORTHY: Shire Plc, J.C. Penney and VisionChina Media were today's noteworthy upgrades:

• Deutsche Bank raised J.C. Penney (NYSE: JCP) to Buy from Hold after channel checks indicated recent sales trends have improved. The firm finds the risk/reward compelling at current levels with a $46 target.
  
• Oppenheimer upgraded shares of VisionChina Media (NASDAQ: VISN) to Outperform from Perform following the recent pullback, after channel checks indicated the company is seeing greater traction with larger advertising clients.

OTHER UPGRADES:

• National Oilwell Varco (NYSE: NOV) was upgraded to Sector Perform from Underperform.
  
• Goldman added US Steel (NYSE: X) to the Conviction Buy List.

It has been a rocky year for Wall Street, but even amid the uncertain market conditions there are some companies that are playing with a lot of cash. In addition, they know how to wisely use their funds, which makes them strong enough to beat any challenge.

One important factor that determines the stability of a company is its corporate cash flow. CNNMoney is looking at stocks with both healthy cash flow and a surplus of cash, which helps them avoid tough situations where they may need to raise their capital (check out its slideshow of these five picks). Another element that CNNMoney takes into account when picking companies is their ability to reinvest cash in ways that assure them a nice profitability.

Let's look at some of the companies that CNNMoney likes:

TheStreet.com's Jim Cramer says the Weyerhaeuser and Bristol-Myers stories slipped under the radar yesterday.

Did anyone even see that Weyerhaeuser (NYSE: WY) (Cramer's Take) made this great trade with International Paper (NYSE: IP) (Cramer's Take), getting out of the commodity container board business and pulling in $6 billion to reduce debt? To me, anytime you get out of a commodity business you lift your multiple, even if the rest is constrained by the housing-related lumber business.

Or how about the story that Bristol-Myers (NYSE: BMY) (Cramer's Take) might sell its baby-food business for a big chunk of change, another $6 billion.

Hmm, $12 billion in shuffles, both good for the shufflers, and no one really cares.

That's the problem with the endless focus on the financials, something I know I am falling prey to, too. Because of the focus, for example, I also missed that Caterpillar (NYSE: CAT) (Cramer's Take) traded back to $68 and change after trading up to $75, a terrific opportunity.

"Value stocks are those whose prices are relatively low compared to their fundamental value, as measured by factors such as earnings and net worth," notes Mark Hulbert.

"Value stocks can be considered all-season stocks, as history shows that they can perform well in both up and down markets." Here, the editor of The Hulbert Financial Digest also offers a list of value stocks that recommended by the most advisors who have also beaten the broad market over the last decade on a risk-adjusted basis.

"Value stocks are to be distinguished from so-called growth stocks, which have relatively high price-to-earnings and price-to-book ratios.

"Consider first how value stocks perform during bear markets. Believe it or not, they on average actually tend to make money. It's not only that they lose less money than the overall market, they actually gain.

"Take the 2000-2002 bear market, for example, during which the overall stock market declined by 48.6% (as measured by the dividend-adjusted version of the Dow Jones Wilshire 5000 index (97199001:Dow Jones Wilshire 5000 Composite Index

"In contrast, according to data compiled by University of Chicago finance professor Eugene Fama and Dartmouth University finance professor Kenneth French, the average value stock over this time gained over 80%.

CNN/Money is good enough to put out the top performing stocks of 2007 list. Most of the companies are fairly familiar, but leading the pack for the S&P 500 is National Oilwell Varco (NYSE: NOV), a stock almost no one has heard of.

The company has been in the right place at the right time. It makes equipment for the oil and gas exploration industry. With the global need for energy rising, NOV is a near-perfect investment.

The firm is not only growing due to a strong industry environment. It is also making what Wall Street thinks are some smart acquisitions. It announced it would buy oilfield service company Grant Prideco (NYSE: GRP) for $7.4 billion in cash and stock. Because the companies are in similar fields, chances are the duplicate costs can be taken out to improve operating margins.

In the September quarter, NOV net income doubled to $366 million, which beat analyst estimates. Backlog for its products also hit a record.

But, the success of National Oilwell Varco points out that in the market, it is better to be lucky than good. The odds that the company could have done so well if oil were at $30 a barrel are probably low. The demand for exploration would be substantially less. The need for drilling equipment would be modest.

National Oilwell Varco had a great year. If oil prices move down, Wall Street should not count on it again.
