"Population growth will likely spur increased demand commodities," says ETF expert Doug Fabian. In Making Money Alert he looks at PowerShares DB Commodity (NYSE: DBC).

"World population growth trends suggest massive numbers of new global citizens on the way -- citizens that are going to require essentials such as food, clothing and shelter.

"For investors who want to ride this population wave, I offer you the PowerShares DB Commodity Index, an exchange-traded fund that seeks to track the performance of the Deutsche Bank Liquid Commodity index.

This post is part of a special annual report -- Top Stock Picks '09 -- in which TheStockAdvisors.com asked 75 leading newsletter advisors to select their favorite investment for the new year.

As his top idea for 2009, fund expert Doug Fabian eyes Powershares DB Crude ETN (NYSE: DXO). In his Successful Investing newsletter, he looks at "an aggressive fund" that moves double the underlying index.

The advisor continues, "I like oil at its year-end 2008 bargain prices. One way to invest in oil and ride its likely rebound during 2009 is to buy the PowerShares DB Crude ETN.

"This is a two beta or double long exchanged traded note. This is an aggressive position and should only be used with more speculative capital.

"In late 2008, oil was trading 60% below its 200-day average, a very rare occurrence. Indeed, oil has fallen 70% from its 2008 highs.

"DXO seeks daily investment results, before fees and expenses, which correspond to twice the daily performance of the Dow Jones U.S. Oil & Gas index. If the Dow Jones U.S. Oil & Gas index moves up 2%, DXO will gain 4%. This ETN could recover strongly in 2009."

"For those who want to 'go green' there are new opportunities to tap the environmental trend by adding cutting edge, alternative energy ETFs to your portfolio," says Doug Fabian, editor of Successful Investing.

"ETF providers are starting to latch onto the green theme. Two fund families, PowerShares and Market Vectors, have created their own classes of clean energy ETFs. A pair of ETFs has been launched in the narrow but potentially profitable niche of solar energy.

"The Claymore/MAC Global Solar Energy Index ETF (NYSE: TAN) is designed to track 25 companies in the solar power industry. Sectors included in the ETF are equipment producers, companies that concentrate on selling electricity, and suppliers of materials or services, installation, integration or finance. TAN currently invests in companies such as MEMC Electronic Materials, Suntech Power Holdings, and LDK Solar Co. Ltd.

"Van Eck Global launched the Solar Energy ETF (ASE: KWT). That solar energy ETF seeks to replicate the price and yield performance of the Ardour Solar Energy Index, which includes companies that generate at least 66% of their revenues from solar energy. The four top holdings are First Solar, Germany's Q-Cells and Solarworld AG, and Norway's Renewable Energy.

"If you've ever read the great E.M. Forster and his seminal novel A Passage To India, you are probably already acquainted with the riches of India's culture," notes leading fund expert Doug Fabian.

In his Successful Investing, the advisor explains, "Now thanks to two new exchange-traded funds, it's going to get easier than ever to get acquainted with the financial riches of India's equity markets."

"WisdomTree Investments launched what it calls the investment industry's first exchange-traded fund focused on India. The fund, called WisdomTree India Earnings Fund (NYSE: EPI), began trading on Feb. 22. Rival ETF provider PowerShares is right behind with its PowerShares India Portfolio (NYSE: PIN).

"WisdomTree India Earnings Fund invests directly in local Indian securities by selecting from a universe of approximately 150 profitable companies that are included in the WisdomTree India Earnings Index.
