"I continue to regard the dip in oil-levered and select energy stocks as a massive buying opportunity," says energy sector specialist Elliott Gue.

The editor of The Energy Strategist explains, "Among individual stocks, I see an opportunity with Baker Hughes (BHI), Schlumberger (SLB), Weatherford International (WFT). All of these companies garner just 5 to 10 percent of their revenues from the deepwater Gulf of Mexico.

In the wake of the incredible volatility of recent days, we turn to several leading financial newsletter advisors, asking "Where's the market going from here?"

Here's an updated assessment -- as well as some select investment ideas -- from Elliott Gue, Richard Moroney, Nicholas Vardy, Keith Fitz-Gerald and Mike Cintolo.

We begin with Elliott Gue, editor of The Energy Strategist, who asserts, "Don't panic. Selling into a panic-driven market is one of the worst and most costly mistakes you can make as an investor. I do not believe the fundamentals justify the downside in my recommended stocks, nor do I see this ballooning into an outright crash or collapse.

"Industrials stocks focus on the manufacturing, transport and construction of physical goods and heavy infrastructure," says Elliott Gue.

The contributing editor to Personal Finance explains, "The best in the sector share one key trait: powerful leverage to a global economic recovery led by growth in the emerging markets and renewed spending on basic infrastructure across the developed world. The S&P 500 Industrials has outperformed the broader market by 20% during the past year."

"Exxon's big acquisitions often serve as a blueprint for the rest of the industry," says energy sector advisor Elliott Gue, referring to its recent $41 billion acquisition of natural gas producer XTO Energy.

In Personal Finance newsletter, he says, "The landmark deal represents a major bet on the future of natural gas and sets the stage for a raft of similar acquisitions by energy majors in 2010." Here's a look at four favorites in the sector.

"Peabody Energy (BTU) remains a buy in our 'gushers portfolio'." says energy sector expert Elliott Gue.

In his The Energy Strategist, he explains, "Strong demand for coal from India and China is a growth story that will play out in 2010."

Gue explains, "Peabody reported its third quarter results and share prices have reacted positively. The weakness in US coal markets remains a challenge, but Peabody has taken steps to shore up profitability in the US, cutting back planned production and locking in contracts for 2010 at fixed prices.

"Highly leveraged casinos were among the first to be locked out of credit markets last year," says Elliott Gue, noting that one company that suffered greatly from credit conditions was Las Vegas Sands (NYSE: LVS).

Now, however, he see "strong propsects" for a recovery in the casino operator's future; he is particularly optimistic on the firm's Asian projects. Here's his review from Personal Finance.

"The economic downturn meant consumers reined in spending on leisure travel and gambling. Meanwhile, declining real estate prices near Las Vegas hit the local economy hard. Gaming revenues declined, and occupancy at Sin City's massive hotels plummeted.

"I'm adding Bucyrus International (NSDQ: BUCY) -- a maker of mining equipment -- to our 'Wildcatters Portfolio' as a play on coal," says Elliott Gue.

In his The Energy Strategist, the advisor explains, "With commodity prices recovering and Chinese demand for coal picking up once again, Bucyrus has likely seen the trough in its new equipment business."

"Bucyrus' top end-market is coal, which accounts for more than three-quarters of the firm's business. Coal mining equipment includes draglines, a sort of giant scoop used to scrape away the overburden (rocks and dirt) that covers coal.

"The oil-services sector remains my favorite long-term play in the energy industry," says sector specialist Elliott Gue. In The Energy Strategist, the advisor looks to industry-leader Schlumberger (NYSE: SLB).

Gue explains, "Oil services firms will benefit directly from the increasing technical complexity of oilfield development. International business is the primary driver for Schlumberger, which generated only 22% of its revenues from North America in 2008.

"The important question is, where do we sit in the cycle for international operations? In my view, the second half of 2010 will mark the beginning of a new uptrend.

"The US natural gas storage cycle is fairly straightforward: More gas is consumed in winter than in summer because natural gas is a key source of heat," explains Elliott Gue.

In his industry-leading The Energy Strategist, the energy sector specialist makes a bullish case for natural gas as well as contract driller Nabor's Industries (NYSE: NBR).

"The year started off with gas storage levels falling in line with the average. In late February or early March that all changed: Storage levels jumped and eventually broke to a new five-year high.

"I'm adding Itron (NSDQ: ITRI) to my diversified portfolio of stocks in the alternative energy space," says Elliott Gue.

In The Energy Strategist he explains, "The firm will benefit from both the HR 2454 bill (a cap-and-trade system designed to reduce U.S. greenhouse gas emissions) and the stimulus bill which included direct subsidies aimed at promoting efficiency and building a more intelligent electric grid.

"Itron is a leading play on energy efficiency and smart grid technologies, a key, near-term component of cutting carbon emissions.

"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.

"Canadian energy giants Suncor Energy (NYSE: SU) and PetroCanada (NYSE: PCZ) announced their intention to merge; Suncor, a holding in our 'Wildcatters Portfolio' will be the surviving entity," says Elliott Gue.

In his The Energy Strategist, he explains, "The combined firm will be the fifth-largest energy company in North America and the largest in Canada." Here, he explains why the new stock remains a buy.

"The combined firm will have more financial flexibility than Suncor did on its own. Debt ratios will be healthier, and the combined firm will also be able to redirect certain planned capital expenditures to higher return potential projects.

Energy sector specialist Elliott Gue sees opportunity in Transocean (NYSE: RIG), a leadin player in the deepwater drilling area. Here's the latest advice from The Energy Strategist.

"The market for deepwater rigs, however, has remained resilient and one drilling with direct leverage to deepwater rigs is US giant, Transocean, the world's largest offshore drilling company, with 136 rigs as well as ten under construction.

"Roughly 68 of those rigs are 'semisubmersibles,' and 39 are ultra-deepwater or deepwater rigs capable of drilling many of the complex plays being targeted around the world today.

"Earnings prospects for companies in the information technology (IT) sector are surprisingly resilient, and one of the best-placed and most recession-resistant IT stocks is IBM (NYSE: IBM)," notes Elliott Gue.

In Personal Finance, he adds, "In the recession of 2001, tech stocks were among the hardest hit groups in the S&P 500, but that was mainly a hangover from the technology bubble of the late 1990s that saw many big-cap tech firms soar to unprecedented valuation levels.

"The tech sector today bears no resemblance to what it was in the early part of this decade. The S&P 500 IT sector now trades at a slight valuation premium to the S&P 500 as a whole, and many of the largest names have impressive, cash-heavy balance sheets.

"Master limited partnerships have been among the market's most stable and reliable groups; but 2008 was a painful exception, with the benchmark index down nearly 37%, the worst performance in its 13-year history," says Elliott Gue.

In Personal Finance he now sees a "great opportunity" for investors to takes positions in this high-yielding sector. Here's a trio of favorite investment plays in the MLP arena.
