Mary Anne and Pamela Aden are among the advisory world's top authorities on metals and resources.

In a recent Q&A session, the editors of The Aden Forecast answer the most common questions that they are asked by readers as to the current state and future outlook for the precious metals markets.

In addition, the sisters answer what they say is the most frequent question they receive: "What is the best way to buy gold." Here, they offer a review of five strategies for investing in gold, including their top picks among stocks, closed-end funds and ETFs.

"There's no question these are dangerous times and the financial world is in uncharted waters," caution resource experts Mary Anne and Pamela Aden.

In The Aden Forecast, the sisters offer an exceptional in-depth discussion on inflationary vs. deflationary foreces, their outlook for precious metals, and their top gold and silver positions for long-term investors.

"The global financial system is on very thin ice, teetering on collapse. Global central banks clearly are literally pulling out all the stops to revive lending and the world economy.

"Will these efforts work? Will they be enough? Those are the most important unanswered questions of the day and only time will tell, but we should know much more in the critical month or so ahead. Why?

"The Fed is spending money at an astronomical rate. It's creating this money out of thin air by monetizing bad debts and whatever else it has to. Remember, this is on top of all the other ongoing government expenses and it's extremely inflationary.

"Normally, there is a lag of about a year or so between money creation and inflation but eventually, what's recently happened will result in massive inflation, a much lower U.S. dollar and a soaring gold price.

"The bottom line is this, if the banks start to lend again, then the economy will be on the road to recovery and inflation. But we know the banks are scared and they're being extremely cautious, for good reason.

Using a proprietary "volume reversal" trading strategy, Mark Leibovit has been consistently ranked among the top newsletter timers. In his VRTrader, he looks at the outlook for stocks, oil, gold & silver -- and offers his choice for exchange-traded funds for traders to play these markets.

Leibovit explains, "The stock market's decline, besides being huge, is relentless. Every rally was met with selling and fresh lows were soon hit. The Dow crashed through the March and January lows and is now trading at its lowest level since September 2006.

"Apparently, that 1500 point rally off the March low was just a giant head fake. The Dow is now down 19% since last October and the S&P is down 18%, approaching bear market territory."

"Breadth is dismal, and down volume is ten times greater than up volume. Sector action is terrible. Seven of the nine market sectors are down more than 2.5%. Ouch! Financials have done it again and have set a new five-year low. Oil spiked through previous records setting a new record high.

"The precious metals also showed strong gains today with gold up 32.80 to 915.10. We cleared the June 9th high of 907.20 touching 909.50 opening up potential to 931.00 (May 21 high).

"Keep your gold for the long-term; it's today's best investment," says Mary Anne and Pamela Aden in The Aden Forecast. "Despite normal ups and downs, we strongly believe you'll be glad that you held hold onto your gold."

"Gold, silver and most of the gold shares are about the only markets to show gains so far this year. Everything else is down, and in many cases down sharply. Gold has recently been hitting new, or multi-year highs against the euro, the Dow Industrials, bonds and oil.

"In other words, it's stronger than these other markets. Gold is outperforming them and the percentage gains are greater in gold compared to all of the other markets.

"Simply put, gold is where you want to be. Silver is good too. These are the best markets. That's why we've consistently stressed keeping a large part of your investments in gold, silver and their shares.
