The Market Vectors Gold Miners ETF (GDX) attempts to replicate as closely as possible the price and yield performance of the Amex Gold Miners Index.

GDX is in a bull market with both the long-term support line and the 200-day moving average at near $40. Although this is a volatile performer, bouncing 10 points between the high and low of its bull channel, the volatility gives us a second chance to buy this stock at a good price.

"There is a very interesting situation developing in the oil and gas industry," says Mike Turner. In the Trade of the Week advisory, he looks at the Oil & Gas Ultra ProShares (NYSE: DIG).

"Even though global economies are not rapidly recovering (although they do seem to be on a positive upslope), and even though there seems to be a bit more supply than demand in the energy markets, oil and gas stocks continue to move higher. What's behind this move?

"Oil has become the inverse proxy to the U.S. dollar. As the dollar weakens, the price of oil is moving higher. With the burgeoning debt piling up in the U.S., the dollar looks to be under pressure to move lower for the foreseeable future.

"Brazil has long been our favorite of the BRIC countries," says Carl Delfeld. In his Chartwell Global Wealth Letter, the advisor looks at two favored Brazilian equity ETFs.

"Brazil seems to have confounded its critics, who view it as a boom and bust economy; the country has been upgraded to investment grade status by Moody's.

"The US ratings agency cited the resilience of the Brazilian economy to the financial crisis for the upgrade of its sovereign debt ratings one notch to Baa3, its lowest investment grade rating.

"This elevation of quality is well earned after years of reform in the country that led to lower inflation and a stronger currency as well as lower levels of government debt.

"Chinese markets have been absolutely soaring this year," says long-standing income expert Carla Pasternak.

In her High Yield Investing advisory, she suggests, "The China Fund (NYSE: CHN) - ranked in the top 1% of funds in the Pacific/Asia ex-Japan category for the latest ten-year period -- should be an excellent way to play this growth story over the long term."

"China's massive stimulus spending and interest rate reductions have succeeded in igniting domestic demand.

I'm issuing a Buy for the United States Natural Gas Fund (NYSE: UNG), but there are several qualifiers, so pay attention.

First, UNG, currently trading around $11.50, a low-cost way for the typical investor to invest in natural gas as a commodity, is a high-risk play. Don't Buy UNG if you're a moderate-risk of low-risk investor.

"It's time to take some profits and play defense for a while," says Glenn Rogers, adding, "Fortunately, we can hedge our bets by taking some profits and building cash reserves and reinvesting in more defensive securities."

In The Internet Wealh Builder, the advisor suggests, a trio of conservative dividend-focused exchange-traded funds.

He explains, "Everybody I talk to these days is nervous, although for different reasons. Some are nervous because they feel left behind. They sat on the sidelines and missed the incredible rally we've had since March. Now they're afraid they won't have a chance to participate because the market has been refusing to correct.

"Others are nervous because they made a pot of money in the rebound and they're afraid they could lose it all in a replay of last year's meltdown. Meanwhile, there some relatively low-risk ETFs where you could park some money while we see how all this plays out.

Investors hoping to ride the climate change bandwagon have had a roller coaster ride over the past two years. Greentech stocks soared with the oil spike in 2007 and 2008, then crashed with stock market and commodity price declines in 2009. Since then, some of the most obvious stock plays have strongly rebounded. Many solar stocks have posted high double-digit gains since rebounding off year-to-date lows in March 2009.

The leading solar panel manufacturer, FirstSolar (NASDAQ: FSLR) has appreciated by 45% from lows of near $100 to a closing price of $154 on October 14. "I wouldn't be stepping into buying these stocks right now," says Pacific Crest senior analyst Mark Bachman, who covers solar stocks. Still, he rates FirstSolar as a market perform and considers it the best solar stock at present on his coverage list.

"Silver may become the next commodity China runs up in price, just as it's done with oil, copper and uranium," exp,ains Peter Krauthis.

Here, the 20-year gold market veteran -- and newest member of The Money Map Reporter team -- looks at the outlook for silver, and the best way to invest in the metal: iShares Silver Trust (NYSE: SLV).

"After 50 years of forbidding precious metals ownership, China's government is now taking the opposite path -- encouraging its citizens to invest in silver. Chinese investors can now buy silver bullion in 500 gram, 1, 2, and 5 kilo bars.

"Reflecting the stability and maturity of its economy and financial markets, Israel was recently upgraded to developed-market status," says fund expert Mark Salzinger.

In The Investor's ETF Report, he looks at iShares MSCI Israel Capped Investable Market ETF (NYSE: EIS), noting, "For a nation of just more than seven million people, Israel generates exceptional economic productivity."

"GDP per capita was recently $28,200, good for 49th in the world, very close to established developed markets like New Zealand and Italy.

With ever growing uncertainty whether our economy will face inflation or deflation in the months to come given recent government spending, what is certain is that no one wants to see their fixed income lose purchasing power. Unlike most bonds that pay out a fixed dollar amount in interest, treasury inflation protected bonds (TIPs) pay out a fixed amount over the consumer-price index (CPI), making them a popular choice for investor anticipating the economy to experience inflation. If inflation is higher than projected, the government adds to your principal on a TIP and makes up the difference!

Not only does owning TIPs allow one to keep up with monthly bills that are increasing in step with inflation, they are an important asset class to consider when determining an asset allocation strategy. TIPs enable one to further diversify a portfolio. Bonds are ideal for those not able to stomach much risk and TIPs in particular protect one's fixed income from eroding.

"We think that junk bonds -- bonds rated BB+ or lower by S&P or Ba1 or below by Moody's -- are worth considering as part of a diversified income portfolio." says Carla Pasternak.

In her High Yield Investing, she asks, "If you agree with us that one's person's junk may turn out to be your treasure, how do you invest?" She answers by offers a pair of junk bond fund ideas.

"SPDR Barclays Capital High Yield Bond ETF (NYSE: JNK) has a $2.2 billion portfolio of 140 junk bonds. Its holds junk bonds in only three sectors: industrials (75.8%), utilities (12.16%) and financials (8.72%).

"It pays a monthly distribution comprised entirely of earnings. JNK is best held in a tax-advantaged account as distributions are taxed at your marginal income tax rate.

"We're seeing tremendous opportunities in China, which should move up regardless of U.S. market gyrations," says Richard Schmidt. In Stellar Stock Alert, he offers his current favorite China plays.

In addition, Jim Trippon, editor of The China Stock Alert, discusses the latest addition to his model portfolio, China's largest life insurance company -- and one with large exposure to Chinese equities.

And finally, fund expert Jim Lowell -- editor of Fidelity Investor -- says, "Investors should be buying Chinese stocks, Hong Kong real estate and Taiwanese technology." He offers some favorite funds for China region exposure.

"While global climate change may be over-politicized, there's no disputing that the issue is real," says Larry Edelson. In his Real Wealth, he looks at two favorite exchange-traded funds that invest in the water sector.

He explains, "Food shortages and the lack of fresh drinking water are likely the most acute and immediate problems. For example, Northwestern India is running out of water, China is raising water prices to curb use and Mexico recently restricted the water supply amid a shortage.

"Domestically, unbridled use of groundwater in Arizona is a potential disaster. The problem is pipelines and canals don't extend far enough to deliver water to everyone. And unrestrained drilling in outlying areas is draining the supply.

"Coal accounts for more than 70% of China's electricity," says Tony Sagami. In Uncommon Wisdom, he looks to an ETF poised to benefit from long-term rising coal demand.

The advisor explains, "China's coal consumption is growing, and it is building coal-powered power plants at a breakneck pace.

"Why? Because they are much cheaper to build and operate than any other power-producing option. China is power starved, and coal is the main resource used for generating electricity in the country.

"I want to profit from a weak dollar," says Jack Adamo. In Insider Plus newsletter, he adds, "We will do it by adding two newly-launched ETFs -- one for silver, one for gold."

"The huge creation of money in the last year must go somewhere. The Fed is creating yet another bubble to offset the deflation in demand.

"Meanwhile, the U.S. dollar has weakened in almost exact proportion to the rise in stock and commodity prices. By keeping interest rates near zero, Central Bankers force investors to participate in the asset inflation unless they're willing to accept zero return on their money.
