"We're adding Brazil's Vale S.A. (NYSE: VALE), the world's leading iron ore producer, to our model growth portfolio," says growth stock expert Stephen Leeb.

In his The Complete Investor, he explains, "This outstanding company offers investors simultaneous stakes in two key areas: iron ore-a commodity essential to any and all infrastructure projects-and Brazil's appreciating currency, the real.

"When it comes to understanding the importance of a commodity such as iron ore, the tale starts with China. Even with China's GDP growth again approaching double digits, the Chinese government continues to aggressively promote growth, offering consumers incentives to buy cars and investing in infrastructure, from roads to bridges to sewers to energy plants.

"The health care picks in our growth portfolio should prosper whatever the outcome of the raging health care debate," suggests growth stock specialist Stephen Leeb.

In The Complete Investor, he explains, "That's because they're leveraged to demographic realities, and in particular to the tide of aging baby boomers," Here, he reviews on portfolio holding -- Teva Pharmaceuticals (NASDAQ: TEVA).

Leeb says, "Israel-based Teva Pharmaceutical is the world's largest manufacturer of generic drugs. Capitalized at $49 billion, Teva pulled in some $11 billion in revenues in 2008, with generic drugs contributing more than two-thirds of those sales.

"CVS Caremark (NYSE: CVS), the nation's largest U.S. drugstore chain, remains a buy in our model growth portfolio," says Stephen Leeb.

In his The Complete Investor, he explains, "Business at CVS has been resilient. In the second quarter, revenue growth was up 22% for its pharmacy benefits management (PBM) business and 17% for retail operations.

"Total sales, almost evenly divided between the two segments, rose 18% to $24.9 billion. Earnings of $886.5 million, or 60 cents a share, were 13% higher than in the year-earlier period and beat consensus estimates by a penny.

"One way to protect yourself in a difficult market environment is to buy shares in low-risk, blue chip companies; one outstanding examples is Microsoft (NASDAQ: MSFT)," suggest Kuen Chan & David Sandell.

In The Complete Investor, they explain, "The company is safe, strong, and able to grow even in a weak economy. It also has more than $25 billion in cash and equivalents and almost no debt."

"Microsoft is near ubiquitous in the computer world. Some version of its Windows operating system runs on roughly 90% of all personal computers, while its Office Suite programs have more than 550 million users.

"Wal Mart Stores (NYSE: WMT), the world's largest retailer, with $405 billion in revenues last year, has remained remarkably strong during the recession even as other retailers have floundered," says Stephen Leeb.

In his The Complete Investor, he explains, " Its low prices have lured more customers, while its product line-up emphasizes items seldom cut from consumer budgets, such as food and health care products." Here's his review.

"Its Wal-Mart stores draw an estimated 100 million people a week, explaining why the company dominates the U.S. supermarket industry, with a better than 25% market share. The company also sells under numerous other names, including Sam's Club.

"In the 2000s, as we've alternated between deflationary and inflationary worries, gold has been the only major investment to rise every year," says Stephen Leeb.

In his The Complete Investor, he explains, "We think that many miners are exceptional bets today. And among our favorite gold investments is one that we hold in our small cap value model portfolio: NovaGold Resources (AMEX: NG)."

"The case for mining stocks is that the price of gold rises faster than miners' costs, allowing margins to increase.

"Overall, we believe quality technology stocks offer above-average growth potential and attractive valuations," says Gregory Dorsey.

In Stephen Leeb's The Complete Investor, he explains, "International Business Machines(NYSE: IBM) has plowed ahead despite a daunting economic and business environment; we are adding the stock to our Growth & Income Portfolio."

"For prudent investors in this challenging economy, most of the major technology companies are financially solid, often with little or no debt and lots of cash on their books. This makes them good long-term vehicles even if the economy remains off the rails for a prolonged period.

"Over the next five years the energy patch should offer some of the best investments around, and one standout is Schlumberger (NYSE: SLB)," says Stephen Leeb in The Complete Investor.

"Schlumberger, by a wide margin, is the best and most dominant. Its services range from well testing to pressure pumping to seismic testing, and it's No. 1 in virtually every area it occupies.

"Some of its operations, especially those that maintain the health of existing wells, are highly recession-resistant.

"Software giant Adobe Systems (NASDAQ: ADBE) has joined our model Growth Portfolio," says Stephen Leeb. Here's his assessment of the tech firm in The Complete Investor.

"When it comes to investing in tech, perhaps the most difficult task is to find one with a bona fide franchise, i.e., an ironclad grip on its market that keeps it largely immune to competition.

"Adobe -- also known as 'the PDF company' -- fits the bill. As most computer users know, PDF files are ones that you can read but can't change in any way-the content is controlled solely by the file's creator.

"With its strong balance Plum Creek Timber (NYSE: PCL) will be able to weather the real estate storm," says growth and income expert Stephen Leeb in The Complete Investor. Here is his look at the timber play.

"Plum Creek, which was added to our model portfolio in November, is the largest and most geographically diverse private landowner in the U.S. and owns more than 7.4 million acres of timberlands in the Pacific Northwest, the South, and the Northeast.

"The solar sector has been notably weak, including First Solar (NASDAQ: FSLR)," says Stephen Leeb. Despite the setback, the editor of The Complete Investor rates the stock a high risk buy.

"First Solar is one of the few whose earnings outperformed consensus estimates: its fourth-quarter results reported yesterday after the market's close were nearly 25% better than estimates.

"First Solar made $1.61 per share this past quarter; Wall Street was expecting $1.30 per share. Revenues were also ahead of estimates, although the company reduced 2009 revenue estimates by about 10%, citing short-term credit concerns for customers.

This post is part of a special report, A Dozen Ways to Play an Obama Building Boom.

"One theme that already seems likely to dominate the playbook for the Obama team is 'infrastructure plus' -- encompassing alternative energy, the environment, and health care," says Patrick DeSouza.

The contributing editor to Steven Leeb's The Complete Investor explains, "These priorities will translate into tremendous opportunities for well-situated firms in these areas." Here are some ideas:

"The Obama Administration is likely to link infrastructure with specific policy priorities such as alternative energies and environmental protection.

"In this way, it can launch public work ventures that create jobs while simultaneously fulfilling campaign promises to tackle climate change and resource degradation. Companies with crossover appeal-a foot in both infrastructure and environmental businesses– are the ones to look at.

"Fluor (NYSE: FLR) and General Electric (NYSE: GE) -- which are already holdings in our growth model portfolio -- both fit this bill, with diversified product lines that range from large-scale infrastructure engineering projects to alternative energy infrastructure to renewable power.

"The economic crisis began in the housing sector and will likely end there," says Stephen Leeb. In his top-notch The Complete Investor he takes a contrary look at two homebuilders.

"Though my view may sound contrarian to a fault, a close look at the housing market, especially given recent government actions, suggests a recovery will happen sooner rather than later and be stronger rather than weaker.

"When home prices decline, buyers pull back, afraid of buying too soon. This leads to further declines and further buyer reluctance. No surprise, then, that housing starts have fallen dramatically.

"Meanwhile, consumers, who had been borrowing money based on the value of their homes, found this source of credit drying up, which dealt a further blow to the economy.

"It is a vicious circle indeed. Ultimately, though, it will almost certainly end with more willing lenders and a stronger housing market as the huge amounts of money being flooded into the system start boosting balance sheets of potential lenders.

"The acronym 'BRIC-standing for Brazil, Russia, India, and China-is in vogue as shorthand for the emergence of the developing world.

"But we're herewith proposing an emended version: 'BRAC'-standing for Brazil, Russia, Australia, and Canada.

"That's because these four countries are the ones most brimming over with essential natural resource, with each one a net exporter of fuels and other natural products. In a world where resource shortages will only get worse, these countries will stand out from the pack.

"Don't get us wrong. China and India remain the largest and fastest growing emerging economies and still face exceptional futures.

"But their major resources are cheap labor, which will become less cheap as their economies keep growing. Indeed, labor costs in these countries already have begun to rise relative to the rest of the world.

"Meanwhile, continued gains in commodities mean that Australia and Canada are gaining relative to the rest of the world. It's hard to overstate just how important relative resource independence is in a world where resources are becoming ever more scarce and expensive.

"When it comes to oil services, the world's most dominant company by far is Schlumberger (NYSE: SLB)," says Stephen Leeb, editor of The Complete Investor. Here, he looks at this "extraordinary" company.

"The question isn't whether inflation will worsen-it's how to protect yourself. Major and obvious lifelines we've stressed include precious metal and commodity companies, especially ones able to boost production.

"For additional inflation insurance, look to what Warren Buffett likes to call 'great companies.' These have two crucial characteristics that allow them to take inflation in stride.

"First, a great company is so dominant in its market that it can pass rising costs along to its customers. And second, it's in a market growing faster than the world's economy.
