For 25 years, Steven Halpern, editor of TheStockAdvisors.com, has surveyed the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is one of 100+ ideas in the Best Stocks for 2008 report.

"The commodity bull market has a long way to run," says Martin Weiss, editor of Money & Markets. "And while individual stocks are inherently more risky than funds, they also have more potential upside. And one area with a lot of upside potential is silver. As such, my top speculative pick for 2008 is Silver Wheaton (NYSE: SLW).

"Silver should ride a tidal wave of fundamentals higher in 2008. Above-ground stockpiles are getting very low, new mine production is lagging, industrial demand is surging and jewelry demand is growing in both China and India.

"And then there's the demand from silver exchange-traded funds, such as iShares Silver Trust (NYSE: SLV), which held over 161 million ounces of silver as of December 7, and keeps growing. India doesn't have a silver ETF yet but should have one in 2008 -- that will bring more demand to bear on the market.

"Silver Wheaton gets 100% of its revenue from silver, and has outperformed both gold and silver this year. It purchases silver from operating mines at a set rate, less than $4 per ounce, insulating it from rising costs. Its production should come in at 13 million ounces in 2007 and rise to 25 million ounces by 2010. Finally, Silver Wheaton has 362.2 million ounces in proven and probable silver reserves.

"The stock isn't cheap, but it is outperforming both gold and silver. And I expect precious metals to head much higher in 2008. Overall, I consider this a red-hot silver play."

With gold turning down from its recent highs, some have questioned whether the 6-year bull market in metals may be ending. According to Mary Anne and Pamela Aden, the evidence points to the opposite conclusion. Indeed, they note, "Gold and silver have everything going for them and their rises have a lot further to go."

Here, the resource experts and co-editors of The Aden Forecast explain the six key factors they see that are pointing to higher metals prices.

The first two reasons are spending and money. They explain, "The world is swimming in money and that's the fuel that's been driving money assets and commodity prices up. But the magnitude of what's currently happening has never been seen before in world history."

The Adens points out that the U.S. is the world's largest debtor nation and "the government keeps spending money it doesn't have."

Since the government doesn't want to cut spending or raise taxes to reduce its debt, they note, "It simply produces money to cover its expenses, which is what governments throughout history have always done, and this amount is also huge."

In fact, in just over the past year, they observe, the amount of paper dollars that've been created is equal to half the value of all the gold that's ever been produced worldwide over the past 2,000 years, which is about $2 trillion. And it's not just the U.S. "Other countries are pumping out money like mad too. In Europe, for instance, money has been growing at the fastest rate in 17 years."

In my recent posts, I have been reviewing the most popular sectors for the coming year, according the the newsletter advisors who participated in the Top Picks from 2007 report. In my last post, I highlighted stocks in healthcare, tech, and telecom. Today, I want to review the resource sectors -- energy and metals -- that remain very popular among advisors, despite being out-of-favor in recent trading.

First, let's look at the metals, where gold remains a popular choice. Sy Harding chose ASA Bermuda, a closed-end gold fund, Curtis Hesler selected Yamana, and Martin Weiss opted for Kinross.

Pamela Aden selected the bullion tracking exchange-traded fund, the streetTracks Gold Trust; Mark Leibovit also chose streettracks Gold. Meanwhile, Mary Anne Aden chose the iShares Silver Trust.

Outside of the precious metals, Tom Bishop chose copper play, Taseko Mines, while Neil Macneale selected steel stocks.

Equally as volatile as metals -- and currently out-of-favor -- has been energy. The energy sector has been high on the list of Top Picks for the past 4 years. This year, however, there is a noticeable shift.
