Oil could record a sluggish six-month period of sluggish prices, moving forward, particularly if the U.S. and global recoveries do not achieve projected GDP growth rates.

Still, investors should view the above as a good opportunity to acquire shares in promising oil plays, which is why I'm Reiterating my Buy rating for Ultra Petroleum Corp. (NYSE: UPL), first recommended on June 4, 2009 at a price of $46.00.

Readers of this space know that one of the preferred sectors is oil / oil services, and with the aforementioned in mind, Ultra Petroleum Corp. (NYSE: UPL) is worth a review.

In general, analysts expect good things in FY2009 from independent oil and natural gas producer Ultra Petroleum. Production should rise 20% in FY2009, following an equally-impressive 20% rise in FY2008.

Among all the negative economic data that came out last week was a positive surprise: retail sales were higher in January. A fluke or a glimmer at the end of the tunnel? That may depend on whether we see any positive surprises arising from items on this week's economic calendar:

• Consumer Analyst Group of New York Conference: Monday through Friday
• NY Empire Manufacturing Index (Feb. 2009): Tuesday, 8:30 AM
• NAHB Housing Market Index (Feb. 2009): Tuesday, 1:00 PM
• Fed's Bullard speaks before National Association of Business Economists: Tuesday, 1:00 PM

• Industrial production (Jan. 2009): Wednesday, 9:15 AM
• Fed's Bernanke speaks before National Press Club Luncheon: Wednesday, 12:30 PM

Seems that even this shortened week was full of news and happenings, in the U.S. and around the world. With Citigroup Inc. (NYSE: C) being bailed out by the U.S. government at the beginning of the week and China announcing fiscal and monetary stimulus plans, the Dow industrials finished in positive territory four days in a row.

But as analysts and pundits, as well as each and every economic release -- in the U.S. and around the world -- remind us, we are not out of the woods yet and the rally has really been a bear-market rally.

Investors looking to take advantage of such rallies, or at least feel they hold stable long-term holdings, can search this week's BloggingStocks' contributors' picks:

Apollo Group (NASDAQ: APOL) and Devry Inc. (NYSE: DV) -- It's often been suggested that educators do well in times of recession and high unemployment as workers look to improve or change their education to get a better job. Leo Fasciocco thinks these two are poised for a breakout.

Dollar Tree Inc. (NASDAQ: DLTR) reported stronger-than-expected earnings this week and also hiked its forecast. Not surprisingly, cash-strapped consumers turn more and more to discounters. Dollar Tree may continue to benefit from the economic downturn and the stock could also experience a short-squeeze rally.

TheStreet.com's Jim Cramer says if the commodity were going to fall further, it would have done so by now.

Has natural gas hit bottom? One thing that has endlessly plagued this market is the belief that there is no bottom to oil or natural gas.

I think that we are seeing some stickiness in oil in the $50s. I am looking for that to be challenged and held today and tomorrow when inventories are broadcast. But more important, I think there is a place where natural gas is having trouble going down now because it is too cold. We are in the season where natural gas should have fallen more before it got here, because without some sort of unseasonably warm snap, we will now believe that nat gas is permanently above $5 and change, where a whole host of prudent companies, like Equitable (NYSE: EQT) (Cramer's Take) for yield and Ultra (NYSE: UPL) (Cramer's Take) for growth, make a lot of money.

We have more than a couple of ways to play this. Equitable has a decent dividend, one of the rare natural gas E&P companies with one of those. Equitable's finding costs are less than half the current pricing. The conservatives can play it with the Chesapeake (NYSE: CHK) (Cramer's Take) preferred; nice upside while you wait. Another way is Anadarko Pete (NYSE: APC) (Cramer's Take), run by industry stalwart Jim Hackett, who came on "Mad Money" recently and said that his company's oil and gas mixture is equal to about $10 a barrel but the stock is only at $37, and I suspect that it could go back to its $35 price if the oil futures stay this gloomy.

TheStreet.com's Jim Cramer says these stocks rise because they're doubly blessed. Integrateds fall because they aren't.

So many people have been puzzled why the major integrateds have not moved with the last $30 rally in oil's spot price. The answer?

They can't take advantage of it.

They either didn't believe, and therefore didn't drill, or they have been so in the crosshairs of sovereign lunacy that they haven't been able to. They didn't have the rigs or they judged that the rigs were so expensive that, like 1980, they would look like dopes when oil came back to $40-$50, where many thought it would. (Go back and check even last year's research for price targets, most of which were from the oil companies' themselves.)

Or maybe it didn't matter anyway. So many of the contracts these companies have signed with governments around the world are either being abrogated or just outright confiscated that you have to ask yourself "Who can invest under those scenarios?" Exxon (NYSE: XOM) (Cramer's Take) in Venezuela. Shell (NYSE: RDS.A) (Cramer's Take) and now BP (NYSE: BP) (Cramer's Take) in Russia. You can't continually invest billions and then write it off because the contracts you wrote don't mean anything.

TheStreet.com's Jim Cramer says as crude goes higher, it makes more and more sense to go for other energy options.

Every day that oil goes up, there is a new set of technologies that had formerly been priced out of the market that comes back to life. Let's take wind. Wind, in itself, just seems so stupid. It needs, well, wind. Much of our country doesn't have enough wind to make this economic. There are only certain regions that can really benefit.

But when oil is at $130, SO WHAT! The parts of the country that have a lot of wind are nuts not to do wind. Wind, when properly integrated into the grid, costs 4 cents a kilowatt. The issue has been shortage of everything that goes into a windmill, because nobody in the chain thought it was worthwhile to mass-produce them. So even though the cost is low, no companies felt it was worth it because the market seemed so niche.

In other words, it was the wind supply chain that was the problem, because we only thought in terms of gigantic plants that created energy. But with nuclear not an option -- never will be in this country, if you ask me -- natural gas falling out of favor post-Katrina as being unreliable, and coal simply intolerable because of the climate problems, wind has become the most natural fuel of all.

TheStreet.com's Jim Cramer says lots of companies now thrive with crude up here.

Oil's not a tax on everything -- it's a tax on the consumer. That's what I come down to when I see the charts this weekend and ponder what's happening in so much of industrial America.

Company after company that I examine -- the new techs, as I call them -- actually benefit from higher oil prices. Or they can pass them on with ease, because of the worldwide demand being so strong.

Take all of the companies involved with making a Boeing (NYSE: BA) (Cramer's Take): Boeing itself, Alcoa (NYSE: AA) (Cramer's Take), Honeywell (NYSE: HON) (Cramer's Take) and Precision Castparts (NYSE: PCP) (Cramer's Take) being good examples. Each of these is necessary because the new Dreamliner burns lots less fuel, and with fuel the biggest airline cost, it stands to reason that higher energy prices make the plane more desirable even at a higher price point.

Or how about all of the companies involved with process and flow control and efficient motors: Parker-Hannifin (NYSE: PH) (Cramer's Take), Emerson (NYSE: EMR) (Cramer's Take), Eaton (NYSE: ETN) (Cramer's Take) and Flowserve (NYSE: FLS) (Cramer's Take). Those work higher with higher energy prices. CSX (NYSE: CSX) (Cramer's Take), Burlington Northern (NYSE: BNI) (Cramer's Take), Kansas City Southern (NYSE: KSU) (Cramer's Take), Union Pacific (NYSE: UNP) (Cramer's Take) and Norfolk Southern (NYSE: NSC) (Cramer's Take) are smaller energy users than trucks, and they ship plenty of ethanol and fertilizer.

TheStreet.com's Jim Cramer says natural gas producers are having a great year, and Anadarko may be the best of the bunch.

Marcellus Shale. Ghana. Brazil. Wherever the oil and gas is. Wherever the chances to boost output.

That's Anadarko (NYSE: APC) (Cramer's Take).

Fifteen percent growth or higher for many years. That's Anadarko.

Creating value for shareholders. That's Anadarko.

IPO of Western Gas. That's Anadarko.

And more important, it is not ExxonMobil (NYSE: XOM) (Cramer's Take).

Anadarko is one of six companies, including Apache (NYSE: APA) (Cramer's Take), Southwestern (NYSE: SWN) (Cramer's Take), XTO Energy (NYSE: XTO) (Cramer's Take), Chesapeake (NYSE: CHK) (Cramer's Take) and Devon (NYSE: DVN) (Cramer's Take) (El Paso (NYSE: EP) (Cramer's Take) is threatening to join them!) that are believers.

TheStreet.com's Jim Cramer says it's not a strong-dollar sell -- the story here is still too good.

Why did natural gas go down last week? What was that? Inventories were down. The commodity price was up. The fuel itself is green. It is better than ethanol and it is being used to fuel an increasing numbers of cars and trucks.

The whole move down had to have been triggered by something, right? Yeah, how about the fact that the stocks were up a lot and were due for some profit-taking.

Recall that the real "reason" they went down is that the dollar "got strong," and that was supposed to trigger commodity deflation; natural gas is a commodity and is therefore going to go down. (Barron's made this very case this weekend, oblivious to the facts, but loving the theory.)

This kind of thinking is just so stupid that it shows you can get chance after chance after chance to own the fuel that can take care of the nation if we just let it. Of course, the stocks began to come back later in the week as threats of supply cut-offs of crude -- they came true this weekend -- made natural gas declines virtually impossible, despite the "sense" that it peaked. So the money has came back and I believe will continue to come back.
