"Our top stock pick for 2011 is a very speculative play, based on our conviction that at some point during the year, gold bullion will experience a strong run-up in price, perhaps reminiscent to the peak that occurred in January 1980," says Alan Newman.

"Gold and silver were top performers in 2010. In fact, they've been top performers over the past eight to 10 years. We believe this will continue in 2011," says resource expert Mary Anne and Pamela Aden.

The co-editors of The Aden Forecast explains, "As the year was drawing to a close, gold hit an all time record high and silver reached a 30 year high. It was super bullish action. And it's not over yet.

"Income-starved investors have flocked this year to master limited partnerships (MLPs); however these securities involve tax and bookkeeping hassles," notes fund specialist Mark Salzinger.

The editor of The Investor's ETF Report explains, "As a result, investing in MLP through an exchange-traded fund -- such as The Alerian MLP ETF (AMLP) -- has numerous advantages.

"Indeed, by holding a single ETF that aggregates income and returns, tax reporting is streamlined (typically on Form 1099, just like corporate dividends).

"The real magic behind lithium is that, pound for pound, this featherweight metal can store more electric energy than just about any other material," notes Nathan Slaughter.

The editor of The ETF Authority explains, "That has made lithium the battery maker's best friend. And portable electronics, power grid infrastructure and hybrid vehicles are a powerful 1-2-3 punch that could send demand soaring.

"Unlike gold, silver and other metals, it's virtually impossible to invest directly in lithium. There are no lithium trading pits, no futures contracts, and no way to take physical possession. Global X Lithium Fund (LIT), a recently launched exchange-traded fund, is the next best thing.

"The biggest opportunity for energy investors today is natural gas. And investors can buy 30 natural gas stocks with one ETF: the First Trust ISE-Reserve Natural Gas ETF (FCG)," says Ian Wyatt.

The editor of The 100K Portfolio explains, "There are many reasons for businesses, consumers, investors and politicians to be bullish on this commodity. Natural gas seemingly has everything we could want from an energy source - it's cheap, clean, and there is an abundance of it throughout our country.

"For this very reason, ExxonMobil, the world's largest energy company, is acquiring one of the leading natural gas companies in the country - XTO Energy.

The $41 billion acquisition will make ExxonMobil the single biggest producer of natural gas, solidifying the company's commanding position in the energy sector. Smart investors should follow Exxon's lead and look to gain exposure to natural gas today.

"Whenever inflation heats up, there's no better place to park your cash than in tangible commodities," says Nathan Slaughter.

In his The ETF Authority, he noes "Our favorite play on this sector is Market Vectors Hard Asset Producers (HAP), an ETF whose 300-stock portfolio provides one-stop shopping for six distinct commodity sub-sectors."

Despite a 46% gain since adding iShares MSCI Brazil (NYSE: EWZ) to his portfolio, global expert Keith Fitz-Gerald still sees upside potential. Here's the latest from Money Map Reporter.

"History tells us that the best gains come to those who have the courage to buy undervalued companies in the face of extreme pessimism – and that sounds a lot like right now. So while we may not be at the very bottom, we are nonetheless pretty darn close.

"The worst crisis of all time, in my view, is the critical global shortage of fresh water," says " Larry Edelson. In Money & Markets, the resource expert offers four water sector plays.

"The world's water crisis is now getting worse by the day. And the global financial and credit crisis is merely one reason why. Another is the ongoing modernization of major parts of the world, which is increasing demand for water, while at the same time polluting it.

"Yet another is major droughts around the world, including in our own back yard, where 60% of the U.S. is officially experiencing a drought.

"New technologies and techniques for better water supply management and improved conservation on the demand side could potentially avert a worldwide disaster. And as a long-term investment, water is one of my favorites. For both its tremendous social cause as well as its profit potential.
